Append black frames to video when audio is longer in ffmpeg
8 April 2018, by EdwardI’m trying to utilize ffmpeg as a video editor and this is mostly due to that the regular video editor dropped more frames than I was comfortable with.
ffmpeg -i "videoplayback1" -t 00:09:51 -i "audioplayback1" -t 00:09:54.38 -vcodec libx264 -crf 20 -acodec copy "playback1.mp4"
As you can see, I’m trimming the video shorter than the audio, but what I want is something that is the opposite of the
-shortest
command switch, to have the file continue for the duration of the audio-t
, and adding physical black frames for the remainder of that time.As it is now, the video is still clipped as if I was using the
-shortest
switch. I tried some-vf
andfilter_complex
but either I get errors, or that the audio is still chopped, the video frozen, but the duration is that of the longest-t
.How would I go about adding black frames for as long as the audio is playing?

-ss in ffmpeg causes black frames
26 April 2016, by DemonedgeI use ffmpeg to cut a video into clips. By this command:
ffmpeg -ss 00:00:00 -i video.mp4 -to 00:01:00 -c copy cut.mp4
Ffmpeg has to cut at key frames, thus when I concatenate each clip back to the entire video, there are some repeated frames at the beginning of each clip. Then I found this command:
ffmpeg -i video.mp4 -ss 00:00:00 -to 00:01:00 -c copy cut.mp4
By putting -i first solves the above problem, but it introduces some frozen frames when I concatenate my video clips back into the whole video. In fact, I saw it introduces some black frames at the beginning of each clip, so when I concatenate these clips back, there are frozen frames.
So is there any way that I can cut my video into clips accurately without introducing black frames or frozen frames in ffmpeg?
