Merge intro to Videos in bulk without re-encoding

[M00nsp3ll]

Hello,

I want to append my intro to videos in bulk without re-encoding but having trouble with it.

I tried ffmpeg - mp4box but the videos must be identical to succeed joining 2 videos without any problem, it gives black screen and just sound if the videos are not exact identical codec, frame rate etc.

software like mp4joiner (https://www.mp4joiner.org/en/) succeeded with the same videos without any problem. It uses also mp4box. As i researched forum Avidemux can do it too.



Could you please help me how to merge my intro to videos in bulk


The code i use with mp4box: (it dont work if the videos are not exact identical)

@echo off
SET INTRO="intro.mp4"
set /A nfile=0
for /R %1 %%v in (input\*.mp4) do (
MP4Box -cat %INTRO% -cat "%%v" "output\%%~nv.mp4"
set /A nfile+=1
)

Best Regards
Thanks

To merge, they must either be the same (encoding settings) to start with, or they must become that way, through re-encoding. Or you don't truly merge, but have a playback playlist.

Those are your options. Pick your favorite.

How can i encode Video1, exactly same like video 2 without video engineering knowledge? is there any trick or software to use?

P.s: mp4joiner does it as it seems. i just join 2 videos without loooking their encoding settings and it works. I just need to do it in bulk
