Add outro in batch to without re-encoding

[M00nsp3ll]

Hello,
is there any software which can add my outro or intro to multiple videos without re-encoding. i can do it with video joiners but i have to do it video by video.
Need a software which can join one file to all videos without re-encoding

Thanks,

Are all videos the same(same video propertis, video/audio codec, etc)? Then can you batch join the intro and outro with ffmpeg. If not then give up.
