Pas question de marché, de cloud etc...
10 avril 2011Le vocabulaire utilisé sur ce site essaie d’éviter toute référence à la mode qui fleurit allègrement

FFMPEG - 2-pass video conversion final file size is larger than expected
14 juin 2022, par Kevin KorbWe are converting files and the target filesize is important. For one version of the video it can not be above 750KB.


We are using the 2-pass encoding and specifying the target audio bitrate and target video bitrate, however the longer the duration of the video, the larger the file becomes and exceeds our 750KB target.




For example, our file is 53.3 seconds, we know our final target of
750KB. We like our audio at 48kbps (mono).


So we calculate our target (total) bitrate at : 750*8/53.3 = 112.57
total kbps Audio bitrate = 48kbps Video bitrate = 112-48 = 64kbps
video


We would expect the file produced to be 746.2KB. (112*53.3 / 8)


The file produced is 850k(ish).




Is there something that takes up space in the file that isn't video or audio that we need to take into consideration ?

FFmpeg synthesizes multiple videos, the final result is only sound, no picture display
6 juillet 2023, par Halifax1、I first converted mp4 to ts:


-i MyVideo.mp4 -vcodec copy -acodec aac -b:v 10000k MyVideo.ts



2、Then scale the ts and fill the empty space:


-i MyVideo.ts -vf pad=width=iw:height=ih:x=-1:y=0:color='White' -b:v 10000k MyVideo_transform.ts



3、Finally use concat to merge into mp4 files:


-i "concat:MyVideo_transform1.ts|MyVideo_transform2.ts" -acodec copy -vcodec copy -absf aac_adtstoasc -b:v 10000k $outputFilePath"



Finally use concat to merge into mp4 files。


I hope that the final merged result can see the video picture。
