Using ffmpeg to trim HEVC video : correct duration, but output file size too large
29 novembre 2022, par ddessertI have a digitized 8mm 16fps HEVC .mp4 that I'm trying to split into clips using
ffmpeg(5.1.2) on MacOS terminal. The output file trims to the correct duration but the filesize is too large.

ffmpeg -ss 05:09 -i input.mp4 -t 02:19 -an -sn -dn -c copy output.mp4


input.mp4: 11:56 in duration and 8.24 GB in filesize (bitrate 674251 kbits/s).

output.mp4: 02:19 in duration and 5.15 GB in filesize (too large).

5.15 GB is the filesize I'd expect for a clip that is 05:09 + 02:19 in duration at
input.mp4's 674251 Kbits/s :

(05:09+02:19) * 674251 kbits/sec = 5.16 GB

I've tried various
-ss start_posand-t durationvalues with similar results. The output file is correctlydurationin time and unexpectedly (start_pos+duration)*bitrate in filesize.

I've consulted this ShotStack.io article on trimming with
ffmpegand this ffmpeg wiki section on cutting small sections from files. Neither specifically states that the resulting file size will be trimmed to match the duration of the clip, but I'd think that'd be useful.

Addendum :

My input file has only one keyframe at t=0.000s. Likely the root of all my problems.

ffmpeg stdout :

FFMPEG not exporting audio OR exports audio with still video
7 septembre 2021, par Zak44Trying to utilize ffmpeg to convert a mp4 to DNxHD, then wrap it in an MXF. The ultimate goal is to get this into Avid Media Composer. I've been having issues with this particular command, where no audio is ever exported :


ffmpeg -y -r 24 -i Test_fix.mp4 -vcodec dnxhd -vsync drop -b:v 36M -s 1920x1080 -threads 2 -vf colormatrix=bt601:bt709 -c:a aac -f rawvideo BLAH.mov


If I tweak the above command by removing the force of the "rawvideo" option I get audio, however the video then sits on the first frame and never advances :


ffmpeg -y -r 24 -i Test_fix.mp4 -vcodec dnxhd -vsync drop -b:v 36M -s 1920x1080 -threads 2 -vf colormatrix=bt601:bt709 -c:a aac -r 24 BLAH.mov


What exactly am I doing wrong ? Here is the output from running the second time :


ffmpeg -y -r 24 -i Test_fix.mp4 -vcodec dnxhd -vsync drop -b:v 36M -s 1920x1080 -threads 2 -vf colormatrix=bt601:bt709 -c:a aac -r 24 BLAH.mov
