In simple terms, it tells how fast an object moves. Speedis a scalar quantity - it has magnitude onlybut not direction. velocity Speed and velocity might seem the same, but they're not. I recently used this slow-mo technique on a highlights video downloaded from YouTube to draw my own conclusions about a specific play. distance speed × time And do the same for time: time distance/speed Speed vs. doubling speed seems to require a different multiple. More confusing is that the atempo setting seems to require reverse logic to setpts i.e. If you care to sync the audio speed with the video speed, things get a bit more complicated: ffmpeg -i input.mp4 -filter_complex "setpts=0.5*PTS atempo=2.0" -map "" -map "" output.mp4 If you use a larger value, the video will display in slower motion. The lower the PTS value, the faster the time-lapse video is generated. Velocity Formula Velocity is nothing but rate of change of the objects position as a function of time. It turns out all you need to do is pass in filter with a PTS ( presentation timestamp) value: Faster Video Speed ffmpeg -i input.mp4 -filter:v "setpts=0.5*PTS" output.mp4 Slower Video Speed ffmpeg -i input.mp4 -filter:v "setpts=2*PTS" output.mp4

One of my favorite TV sports illustration techniques is speeding video up (time-lapse) or slowing it way down (slo-mo replay) naturally I wanted to know how to manipulate video speed with ffmpeg.

I don't have their advanced TV software or hardware, of course, but I do have a love for ffmpeg, which allows me to do everything from clip videos to change video formats, create tacky highlight videos with emo techno music combine audio and video, and more. The gradient of a straight line 18.I watch a lot of sports and recently I've become fascinated with some of the methodologies they use to illustrate events within the game. : STD (Speed,Time, & Disrtance) Calculator : Office Products.
GCSE Physics Keywords: Gradient, Rise, Run, Distance, Time, Speed There are some CEA VIC numbers with multiple timings that differ slightly in their Vtotal, and thus in their refresh rates. This would have given us the same result.) (Note that you could also have used the formula: Average Speed = Distance travelled / Time taken The speed shown in this distance time graph is therefore 5 m/s. You can use it to accelerate (speed up) or slow down any video file, e.g., to make a slow-motion video.

Use the formula: Gradient = Rise/Run and sub-in the numbers Welcome to a free online tool for changing video playback speed. Then enter the time value and then select the conversion designation for the speed answer. Now move up the vertical side of the triangle a distance of 50 metres. In the Speed calculator, enter the distance value and conversion units designation. Starting at point A, we move 10 seconds along the base of the triangle, so the 'run' is +10 secs. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators. Now draw a right-angled triangle with two horizontal and vertical sides. These are quite far apart so that will make our gradient calculation more accurate. To find the speed of an object from a distance-time graph, we need to calculate the gradient (or slope) of the line.įirst choose two points that lie the line - say point A is (0, 0) and point B is (10, 50). Playback Speed Calculator - Audiobook Speed Calculator - Shows Sped Up Time Saved If I set the reading speed at 1.25, how fast does that make. Length: Hours: Minutes: Seconds: Playback Speed: Result: Calculated time: 1.25 speed. Calculating the speed from a distance-time graph Calculate the video or podcast length on the given playback speed.
