• How to make multiple edits to a single video file, and then encode once in ffmpeg ?

  4 juin 2022, par Edesem

  I simply want to be able to do actions such as trimming videos and concatenate videos possibly mulitples times for one video file without encoding each time, and then finally at the end encode once. This would be similar to how normal video editors work where you can make all the edits first and then encode at the end ?

  


  Is this possible ? Alternatives ? Currently it is very inefficient and bad for quality that if I want to cut out some parts of a video I have to wait for it to reencode and then do the next edit one after the other.

  


  Thank you.

  


• FFmpeg does not always fully concat video ?

  25 juin 2014, par user3550401

  I’m trying to concat two video clips, sometimes i end up with only three fourths of the video, sometimes I only get one half, and sometimes i manage to get the whole thing. Anyone ever deal with this ? Here is my ffmpeg command :

  ffmpeg -i "concat:videos/clip1.ts|videos/clip2.ts"  -ar 44100  -b:a 128k -b:v 800k -vcodeclibx264 -bsf:v h264_mp4toannexb -f mpegts -t 120 videos/output.ts

  I just dont understand why sometimes it works perfectly and other times i only get part of the video.

• FFMPEG not turning a series of .ppm files into a video

  I don't have much of an idea of what i'm doing.
also i don't use stackoverflow so i still don't know what i'm doing xd

  


  I'm trying to do this : ffmpeg -framerate 45 -i screen_200x200_%d.ppm -c:v libx264 -r 30 -pix_fmt yuv420p output52234.mp4 and it's making this appear :
