I recently used this slow-mo technique on a highlights video downloaded from YouTube to draw my own conclusions about a specific play. 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. 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. For example, the bowling speed of Wahab Riaz, a Pakistani bowler, is 144.8kmh -1.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.

Satellites are sent into an orbit around the earth while keeping in view escape velocity (11.2 Kms -1). With this calculator, you can: Calculate speed, given distance and time By inputting speed and distance, calculate time Calculate distance Compare the time with a different speed, using the advanced mode in the calculator. Open the Video Cutter in your browser using any device (phone, PC or tablet).The minute hand of a watch moves with a velocity of 0.0017 rads -1.Now if one reverses the car after stopping for a while at a speed of 20kmh -1, the velocity will be -20kmh -1. Velocity Formula Velocity is nothing but rate of change of the objects position as a function of time. Let the car be moving at 140kmh -1 in the south. There must be some speed (magnitude of velocity) with which the car is being driven and of course a direction also. When one is driving a car from the office back home. We use the concept of velocity in daily life a lot. After this, the upload time calculator will provide you with the estimation you need. Then enter your internet speed and choose the unit of measurement from the drop-down menu.

When a body is moving in a circle, it’s moving with angular velocity and it is directed towards the center of the circle. Here are the steps to follow: First, enter the size of the file you want to download then choose the unit of measurement from the drop-down menu. When a body is moving along a straight path, the velocity of the body is linear. The dimension of velocity is [ LT^\Big) V i n s = limit as Δ t approaches to zero ( Δ t Δ d ) Linear velocity: A: It is a very handy tool that helps you select the specific lens, lighting, frame rate, and memory settings to get the best video / images for your high-speed. It is defined completely by magnitude and direction. By definition, the time rate of change of displacement is called velocity.
