ffmpeg terminal : How can I re-encode a video file using all the parameters copied from another video ? [closed]
5 décembre 2022, par LeverI have two videos A and B. How can I re-encode B using ALL the parameters of A ?
I would like to use both A and B as inputs, but all parameters are extracted from A, then B is re-encoded with the A-parameters including both video and audio. Is there a simple command to copy ALL the parameters of A ?


Thanks !


I know the typical parameters of a video includes the resolution, fps and so on. But it seems that I always miss something rather than get ALL the parameters to make A and B the same.


The background is that I need to concatenate about 100 videos, but only a few of which has lower quality than others. I don't want to re-encode all of them. Therefore I'm trying to re-encode the lower ones to match the others, and then I can use the file-level concatenation command avoiding re-encode all of them.

Cropping black bars in video with ffmpeg on ubuntu changes video size
9 décembre 2013, par pramodI have a source video size that's 720x576 with black rectangles on the top and bottom.
I want to remove the black rectangles and set the output video size to 640x352.
I tried
-vf cropdetect
and the value it gave was 640:192:0:80.However, putting that same value in
crop=<parameter></parameter>
changes the output video size.How can I fix this ?
E.g. :
ffmpeg -i all_the_best_test.mpg -s 640x352 -deinterlace -b 500k -minrate 500k \
-maxrate 500k -aspect 1.82 -force_fps -vcodec libx264 -me_method 10 \
-vf crop=640:192:0:80 -r 25 -acodec libfaac -ac 2 -ar 44100 -ab 96k -subq 6 \
