Create video with correct FPS from video with incorrect FPS and file containing timestamps for each frame using FFMPEG
4 février 2023, par BojanI have a video file captured from web camera and using OpenCV in python. The nominal FPS of the web cam is 30 FPS, but because of the environment, the actual FPS varies and sometimes can go as low as 24 fps. The recorded video is created using OpenCV's
VideoWriter
, using MP4V FOURCC and always has FPS value of 30, which makes the video's duration incorrect if the actual FPS was not 30. I have a file which contains the timestamps when each frame from the web cam was read (generated using python'stime.time()
).

Question :

Using FFMPEG (or other software) can I use the timestamps information to create new video file (probably VFR file) and then convert it to CFR file ?

I am not sure what is the correct approach to create video file with correct time base.
Maybe I can split the video's frames and save them as images and then use the timestamps and the images to create VFR video, but I want to see if it is possible to do this in another, more elegant way.


Thanks in advance !
