You need to learn all the fine points. Bezier points give you the most control over easing. There are built in tools you have to become familiar with to help do things like move all keyframes at once, or reverse their timing, etc.

Group, group, group, group, group. Everything contained within a group behaves according to that parent group’s coordinate system. Also – when setting up an animation, it really helps to make sure everything starts off at center screen 0,0 , then work the developed shapes from there. Place hand group in forearm group. Match the anchor point of the hand group to the end of the arm. Place the Forearm group in with the Upper arm group.

Set the Anchor point to the end of the Upper Arm. Animate the forearm and the forearm and the hand move together from the anchor point at the end of the upper arm. Animate the hand and it moves separately from both forearm and upper arm — BUT always remains attached to the forearm at the anchor point. Motion is different than AE. It will take some getting used to. However, I don’t believe there is very much you cannot do that you can do in AE, you just might have to go about obtaining your goals in a slightly different and usually simpler way.

The other thing to love about Motion: it’s not a subscription. Updates have been free since Sep 18, PM. I end up using “continuous” and “ease” more than bezier because of what I described in my OP. If I set the keyframes to bezier, I basically have to eyeball the bezier weights, and there is no way to specify a weight so it actually be comes an impossible task.

Even if I select the start keyframes and cmd drag to start a new bezier weight, depending on the value of the keyframes the weight added won’t be proportional to the amount of movement occurring in that parameter.

So, basically, bezier anim curves are more or less useless when there are keyframes on multiple transform properties. Super frustrating. I know there’s a keyframe weight value on the backend, why can’t I type it in to specify it? Motion is not AE. There’s no way to type in “expressions”. Well, there is There’s no such thing as a “weighted” keyframe There is a Custom Behavior that can be used to provide additive changes to an animation.

Similar additive changes can be made with a Link behavior and even multiplicative changes Try the Ramp behavior. You can set the Start and End Values of the animation. There’s a Curvature control but you still won’t get the amount of easing as you get with Bezier control. You can set the start frame and end frame of the animation from within the behavior.

There’s an Overshoot behavior that will let you create an animation that oscillates “bounces” at the end It will take you some time to become accustomed to it. It has more in common with Photoshop than AE.

I came to it via Photoshop. It actually replaced PS for me even before the stupid “subscription model” rolled out. You’re either going to have to take some time to adjust to the differences in Motion, or go back to AE if you simply must have a particular feature of keyframing.

I personally don’t use it, and have never fallen short of accuracy, maybe because my Motion sessions are all 50fps due to my shooting equipment being 50fps BTW, this may be a mistake from me, but should the session’s fps not be the same as the real footage’s, hence 50fps for me? Thank you. Sep 24, AM. Sep 24, PM in response to joelle In response to joelle Frame Rates in Motion are a “convenience”.

You can make your templates 10fps and there are a LOT of advantages to doing this. The template will look a little choppy in Motion, but you cannot tell the difference in FCPX — subframe keyframing allows for whatever keyframes you use at 10fps to interpolate to fractional frames positions in FCPX or so that is how I perceive it It may not make any difference.

I just always have subframe keyframes turned on. Sep 24, PM. In my 50fps Motion-only projects though yeah, I know Then I sometimes get choppy images if I slow these footages down too much.

Would it be any less choppy if I chose, say 30 fps as the actual fps for the project, i. If you’re dealing with video in a Motion project, your frame rate should match the video except fractional frame rates – take this opportunity to FIX your video with a modern frame rate [24, 25, 30, 50, or 60] – use the nearest whole number frame rate closest to the video.

Slowing video down is always going to be a problem if you don’t have the frames for it best results are to shoot at 60 to fps [or more]. The quality of slowing down video will also be dependent on actual photographic specs if you have a high shutter rate, you’re going to minimize natural motion blur and the differences between frames will be more noticeable. You might be able to mitigate some choppiness by turning on motion blur and picking a compatible Shutter Angle and Samples.

That may take some experimentation — or give WideTime a try. Posted on Sep 28, AM. Page content loaded. Sep 28, AM. Don’t think there is anything I’d like “to add” to this effect.

Custom FPS in FCPX? – Apple Community

 
To start the conversation again, simply ask a new question. They keyframe editor drives me nuts. The projects I am experiencing this on are very simple beginner projects with 1 group, 1 gradient, 1 filter, 1 text object, 1 behavior. Preparing video on my internal drive is pretty much out of the question.

Under structural applications, measuring and recording how a structure dynamically responds to these inputs is critical for assessing the safety and viability of a structure.

This type of monitoring is called Health Monitoring, which usually involves other types of instruments, such as displacement sensors -Potentiometers, LVDTs, etc. Within the last several years, several companies have produced and marketed sports watches for runners that include footpods , containing accelerometers to help determine the speed and distance for the runner wearing the unit.

In Belgium, accelerometer-based step counters are promoted by the government to encourage people to walk a few thousand steps each day. Herman Digital Trainer uses accelerometers to measure strike force in physical training. It has been suggested to build football helmets with accelerometers in order to measure the impact of head collisions.

Accelerometers have been used to calculate gait parameters , such as stance and swing phase. This kind of sensor can be used to measure or monitor people. An inertial navigation system is a navigation aid that uses a computer and motion sensors accelerometers to continuously calculate via dead reckoning the position, orientation, and velocity direction and speed of movement of a moving object without the need for external references.

Other terms used to refer to inertial navigation systems or closely related devices include inertial guidance system, inertial reference platform, and many other variations.

An accelerometer alone is unsuitable to determine changes in altitude over distances where the vertical decrease of gravity is significant, such as for aircraft and rockets. In the presence of a gravitational gradient, the calibration and data reduction process is numerically unstable. Accelerometers are used to detect apogee in both professional [29] and in amateur [30] rocketry. Accelerometers are also being used in Intelligent Compaction rollers.

Accelerometers are used alongside gyroscopes in inertial navigation systems. One of the most common uses for MEMS accelerometers is in airbag deployment systems for modern automobiles.

In this case, the accelerometers are used to detect the rapid negative acceleration of the vehicle to determine when a collision has occurred and the severity of the collision. Another common automotive use is in electronic stability control systems, which use a lateral accelerometer to measure cornering forces. The widespread use of accelerometers in the automotive industry has pushed their cost down dramatically. Tilting trains use accelerometers and gyroscopes to calculate the required tilt.

Modern electronic accelerometers are used in remote sensing devices intended for the monitoring of active volcanoes to detect the motion of magma. Accelerometers are increasingly being incorporated into personal electronic devices to detect the orientation of the device, for example, a display screen.

A free-fall sensor FFS is an accelerometer used to detect if a system has been dropped and is falling. It can then apply safety measures such as parking the head of a hard disk to prevent a head crash and resulting data loss upon impact.

This device is included in the many common computer and consumer electronic products that are produced by a variety of manufacturers. It is also used in some data loggers to monitor handling operations for shipping containers.

The length of time in free fall is used to calculate the height of drop and to estimate the shock to the package. Some smartphones , digital audio players and personal digital assistants contain accelerometers for user interface control; often the accelerometer is used to present landscape or portrait views of the device’s screen, based on the way the device is being held.

Apple has included an accelerometer in every generation of iPhone , iPad , and iPod touch , as well as in every iPod nano since the 4th generation. Along with orientation view adjustment, accelerometers in mobile devices can also be used as pedometers , in conjunction with specialized applications. Automatic Collision Notification ACN systems also use accelerometers in a system to call for help in event of a vehicle crash.

Many accelerometer-equipped smartphones also have ACN software available for download. ACN systems are activated by detecting crash-strength accelerations.

Accelerometers are used in vehicle Electronic stability control systems to measure the vehicle’s actual movement. A computer compares the vehicle’s actual movement to the driver’s steering and throttle input.

This can help prevent the vehicle from spinning or rolling over. Some pedometers use an accelerometer to more accurately measure the number of steps taken and distance traveled than a mechanical sensor can provide. Nintendo’s Wii video game console uses a controller called a Wii Remote that contains a three-axis accelerometer and was designed primarily for motion input.

Users also have the option of buying an additional motion-sensitive attachment, the Nunchuk , so that motion input could be recorded from both of the user’s hands independently. Is also used on the Nintendo 3DS system. The Sony PlayStation 3 uses the DualShock 3 remote which uses a three axis accelerometer that can be used to make steering more realistic in racing games, such as MotorStorm and Burnout Paradise. The Nokia sport features a 3D accelerometer that can be accessed from software.

It is used for step recognition counting in a sport application, and for tap gesture recognition in the user interface. Tap gestures can be used for controlling the music player and the sport application, for example to change to next song by tapping through clothing when the device is in a pocket.

Other uses for accelerometer in Nokia phones include Pedometer functionality in Nokia Sports Tracker. Some other devices provide the tilt sensing feature with a cheaper component, which is not a true accelerometer. A microphone or eardrum is a membrane that responds to oscillations in air pressure. These oscillations cause acceleration, so accelerometers can be used to record sound. Conversely, carefully designed sounds can cause accelerometers to report false data.

One study tested 20 models of MEMS smartphone accelerometers and found that a majority were susceptible to this attack. A number of 21st-century devices use accelerometers to align the screen depending on the direction the device is held e. Such devices include many tablet PCs and some smartphones and digital cameras.

The Amida Simputer , a handheld Linux device launched in , was the first commercial handheld to have a built-in accelerometer. It incorporated many gesture-based interactions using this accelerometer, including page-turning, zoom-in and zoom-out of images, change of portrait to landscape mode, and many simple gesture-based games.

As of January , almost all new mobile phones and digital cameras contain at least a tilt sensor and sometimes an accelerometer for the purpose of auto image rotation, motion-sensitive mini-games, and correcting shake when taking photographs.

Camcorders use accelerometers for image stabilization , either by moving optical elements to adjust the light path to the sensor to cancel out unintended motions or digitally shifting the image to smooth out detected motion. Some stills cameras use accelerometers for anti-blur capturing. The camera holds off capturing the image when the camera is moving. When the camera is still if only for a millisecond, as could be the case for vibration , the image is captured.

An example of the application of this technology is the Glogger VS2, [40] a phone application which runs on Symbian based phones with accelerometers such as the Nokia N Some digital cameras contain accelerometers to determine the orientation of the photo being taken and also for rotating the current picture when viewing.

Many laptops feature an accelerometer which is used to detect drops. If a drop is detected, the heads of the hard disk are parked to avoid data loss and possible head or disk damage by the ensuing shock.

A gravimeter or gravitometer, is an instrument used in gravimetry for measuring the local gravitational field. A gravimeter is a type of accelerometer, except that accelerometers are susceptible to all vibrations including noise , that cause oscillatory accelerations. This is counteracted in the gravimeter by integral vibration isolation and signal processing.

Though the essential principle of design is the same as in accelerometers, gravimeters are typically designed to be much more sensitive than accelerometers in order to measure very tiny changes within the Earth’s gravity , of 1 g.

In contrast, other accelerometers are often designed to measure g or more, and many perform multi-axial measurements. The constraints on temporal resolution are usually less for gravimeters, so that resolution can be increased by processing the output with a longer “time constant”.

Accelerometer data, which can be accessed by third-party apps without user permission in many mobile devices, [42] has been used to infer rich information about users based on the recorded motion patterns e. Additionally, millions of smartphones could be vulnerable to software cracking via accelerometers. From Wikipedia, the free encyclopedia. Device that measures proper acceleration.

Main article: Condition monitoring. Therefore, if one were to gather an immense number of carob seeds and form them into an enormous sphere, then the gravitational field of the sphere would be proportional to the number of carob seeds in the sphere. Hence, it should be theoretically possible to determine the exact number of carob seeds that would be required to produce a gravitational field similar to that of the Earth or Sun.

In fact, by unit conversion it is a simple matter of abstraction to realize that any traditional mass unit can theoretically be used to measure gravitational mass. Measuring gravitational mass in terms of traditional mass units is simple in principle, but extremely difficult in practice. According to Newton’s theory, all objects produce gravitational fields and it is theoretically possible to collect an immense number of small objects and form them into an enormous gravitating sphere.

However, from a practical standpoint, the gravitational fields of small objects are extremely weak and difficult to measure. Newton’s books on universal gravitation were published in the s, but the first successful measurement of the Earth’s mass in terms of traditional mass units, the Cavendish experiment , did not occur until , over a hundred years later. Henry Cavendish found that the Earth’s density was 5.

As of , the Earth’s mass in kilograms is only known to around five digits of accuracy, whereas its gravitational mass is known to over nine significant figures. Given two objects A and B, of masses M A and M B , separated by a displacement R AB , Newton’s law of gravitation states that each object exerts a gravitational force on the other, of magnitude. The above statement may be reformulated in the following way: if g is the magnitude at a given location in a gravitational field, then the gravitational force on an object with gravitational mass M is.

This is the basis by which masses are determined by weighing. In simple spring scales , for example, the force F is proportional to the displacement of the spring beneath the weighing pan, as per Hooke’s law , and the scales are calibrated to take g into account, allowing the mass M to be read off. Assuming the gravitational field is equivalent on both sides of the balance, a balance measures relative weight, giving the relative gravitation mass of each object.

Inertial mass is the mass of an object measured by its resistance to acceleration. This definition has been championed by Ernst Mach [19] [20] and has since been developed into the notion of operationalism by Percy W. In classical mechanics, according to Newton’s second law , we say that a body has a mass m if, at any instant of time, it obeys the equation of motion.

This equation illustrates how mass relates to the inertia of a body. Consider two objects with different masses. If we apply an identical force to each, the object with a bigger mass will experience a smaller acceleration, and the object with a smaller mass will experience a bigger acceleration. We might say that the larger mass exerts a greater “resistance” to changing its state of motion in response to the force. However, this notion of applying “identical” forces to different objects brings us back to the fact that we have not really defined what a force is.

We can sidestep this difficulty with the help of Newton’s third law , which states that if one object exerts a force on a second object, it will experience an equal and opposite force.

To be precise, suppose we have two objects of constant inertial masses m 1 and m 2. We isolate the two objects from all other physical influences, so that the only forces present are the force exerted on m 1 by m 2 , which we denote F 12 , and the force exerted on m 2 by m 1 , which we denote F Newton’s second law states that. Suppose that these accelerations are non-zero, so that the forces between the two objects are non-zero.

This occurs, for example, if the two objects are in the process of colliding with one another. Newton’s third law then states that. If a 1 is non-zero, the fraction is well-defined, which allows us to measure the inertial mass of m 1. In this case, m 2 is our “reference” object, and we can define its mass m as say 1 kilogram. Then we can measure the mass of any other object in the universe by colliding it with the reference object and measuring the accelerations.

Additionally, mass relates a body’s momentum p to its linear velocity v :. The primary difficulty with Mach’s definition of mass is that it fails to take into account the potential energy or binding energy needed to bring two masses sufficiently close to one another to perform the measurement of mass. Thus, for example, if the reference weight m 2 is taken to be the mass of the neutron in free space, and the relative accelerations for the proton and neutron in deuterium are computed, then the above formula over-estimates the mass m 1 by 0.

Typically, the mass of objects is measured in terms of the kilogram, which since is defined in terms of fundamental constants of nature. The mass of an atom or other particle can be compared more precisely and more conveniently to that of another atom, and thus scientists developed the dalton also known as the unified atomic mass unit. By definition, 1 Da one dalton is exactly one-twelfth of the mass of a carbon atom, and thus, a carbon atom has a mass of exactly 12 Da.

In some frameworks of special relativity , physicists have used different definitions of the term. In these frameworks, two kinds of mass are defined: rest mass invariant mass , [note 9] and relativistic mass which increases with velocity. Rest mass is the Newtonian mass as measured by an observer moving along with the object. Relativistic mass is the total quantity of energy in a body or system divided by c 2.

The two are related by the following equation:. The invariant mass of systems is the same for observers in all inertial frames, while the relativistic mass depends on the observer’s frame of reference.

In order to formulate the equations of physics such that mass values do not change between observers, it is convenient to use rest mass. The rest mass of a body is also related to its energy E and the magnitude of its momentum p by the relativistic energy-momentum equation :. So long as the system is closed with respect to mass and energy, both kinds of mass are conserved in any given frame of reference. The conservation of mass holds even as some types of particles are converted to others.

Matter particles such as atoms may be converted to non-matter particles such as photons of light , but this does not affect the total amount of mass or energy. Although things like heat may not be matter, all types of energy still continue to exhibit mass. The “relativistic” mass and energy concepts are related to their “rest” counterparts, but they do not have the same value as their rest counterparts in systems where there is a net momentum.

Because the relativistic mass is proportional to the energy , it has gradually fallen into disuse among physicists. In bound systems, the binding energy must often be subtracted from the mass of the unbound system, because binding energy commonly leaves the system at the time it is bound.

The mass of the system changes in this process merely because the system was not closed during the binding process, so the energy escaped. For example, the binding energy of atomic nuclei is often lost in the form of gamma rays when the nuclei are formed, leaving nuclides which have less mass than the free particles nucleons of which they are composed. Mass—energy equivalence also holds in macroscopic systems.

In general relativity , the equivalence principle is the equivalence of gravitational and inertial mass. At the core of this assertion is Albert Einstein’s idea that the gravitational force as experienced locally while standing on a massive body such as the Earth is the same as the pseudo-force experienced by an observer in a non- inertial i. However, it turns out that it is impossible to find an objective general definition for the concept of invariant mass in general relativity.

At the core of the problem is the non-linearity of the Einstein field equations , making it impossible to write the gravitational field energy as part of the stress—energy tensor in a way that is invariant for all observers. For a given observer, this can be achieved by the stress—energy—momentum pseudotensor.

In classical mechanics , the inert mass of a particle appears in the Euler—Lagrange equation as a parameter m :. After quantization, replacing the position vector x with a wave function , the parameter m appears in the kinetic energy operator:. In the ostensibly covariant relativistically invariant Dirac equation , and in natural units , this becomes:. A tachyonic field , or simply tachyon , is a quantum field with an imaginary mass.

The term ” tachyon ” was coined by Gerald Feinberg in a paper, [39] but it was soon realized that Feinberg’s model in fact did not allow for superluminal speeds. This process is known as tachyon condensation.

Well known examples include the condensation of the Higgs boson in particle physics , and ferromagnetism in condensed matter physics. Although the notion of a tachyonic imaginary mass might seem troubling because there is no classical interpretation of an imaginary mass, the mass is not quantized. Rather, the scalar field is; even for tachyonic quantum fields , the field operators at spacelike separated points still commute or anticommute , thus preserving causality. Therefore, information still does not propagate faster than light, [39] and solutions grow exponentially, but not superluminally there is no violation of causality.

Tachyon condensation drives a physical system that has reached a local limit and might naively be expected to produce physical tachyons, to an alternate stable state where no physical tachyons exist. Once the tachyonic field reaches the minimum of the potential, its quanta are not tachyons any more but rather are ordinary particles with a positive mass-squared. This is a special case of the general rule, where unstable massive particles are formally described as having a complex mass, with the real part being their mass in the usual sense, and the imaginary part being the decay rate in natural units.

An unstable particle is a state which is only approximately constant over time; If it exists long enough to be measured, it can be formally described as having a complex mass, with the real part of the mass greater than its imaginary part. If both parts are of the same magnitude, this is interpreted as a resonance appearing in a scattering process rather than a particle, as it is considered not to exist long enough to be measured independently of the scattering process.

In the case of a tachyon, the real part of the mass is zero, and hence no concept of a particle can be attributed to it. In a Lorentz invariant theory, the same formulas that apply to ordinary slower-than-light particles sometimes called ” bradyons ” in discussions of tachyons must also apply to tachyons. In particular the energy—momentum relation :. This equation shows that the total energy of a particle bradyon or tachyon contains a contribution from its rest mass the “rest mass—energy” and a contribution from its motion, the kinetic energy.

When v is larger than c , the denominator in the equation for the energy is “imaginary” , as the value under the radical is negative. Because the total energy must be real , the numerator must also be imaginary: i. From Wikipedia, the free encyclopedia. Quantity of matter. This article is about the scientific concept.
