How can i burn in the current video playback percentage on to a video stream using FFMpeg
25 mai, par David ClewsI've taken alook at the drawtext filter in ffmpeg and it offers the ability to burn in the current local time directly on to the video stream. I would like this sort of behaviour but for a integer percentage value and the percentage symbol % after the actual value. I don't know if this is possible using FFMpeg on the command line. The formula should be something like.


ceil((t/duration)*100)

Does file size of an encoded video scales proportionally with FPS if a video is encoded in H265 ?
20 juin 2021, par user482594If I encode a raw 60fps video with an H.265 encoder, one with 30 fps and the other with 60fps, would the file size of a 60fps encoded video be as twice as big as 30fps H.265 video ? (assuming all other parameters are the same. e.g. Same CRF/twopass parameters)


In other words, if I happen to encode the same source video with 10 fps, would the outcome encoded video has about 1/6 the file size of 60 fps encoded video ?

FFmpeg : how to make output video has the same width, height, and SAR with input video
8 décembre 2014, par user2927954I have 2 videos : v1.mp4 and v2.mp4. I want to make a output video that is a copied-v2.mp4 video but has the same width, height, SAR with v1.mp4.
How could i do that by ffmpeg command ?I think about the command :
ffmpeg -i v1.mp4 -i v2.mp4 -filter_complex [1:v]scale={width_of_v1}:{height_of_v1},setsar={sar_of_v1}[out] out.mp4
but i do not know how to get those values : width_of_v1, height_of_v1, sar_of_v1
