Avidemux merge video5/8/2023 ![]() ![]() YAMP/MP4box is trying to jam everything into the one container, one after another, and is probably succeeding in some way - but the result is undefined. Even using the exact same codec with the exact same settings for each video won't necessarily guarantee videos that are exactly the same in the ways needed for them to be joined together. That's what the mp4 container is like.įor some reason, your videos aren't exactly the same. Imagine a mailing tube that can hold several posters - but only if they're exactly the same size, use exactly the same colours, printed on exactly the same paper, etc. As far as I'm aware, the mp4 container can hold multiple videos, just like a mailing tube - but, unlike a mailing tube, they must all be created using exactly the same parameters*. The real problem comes when it's time to put these all together. MP4 ASP, MP4 AVC, etc - again, using the poster analogy, you could consider these to be like standard poster sizes, e.g. As well as all these options, there are some standard "pre-defined" options, e.g. These correspond to all the different options you have when creating mp4-compressed video - different image sizes, framerates, frame types, methods and limitations of arranging those frames, etc, etc. To take the poster example further: posters can be various sizes, use various colours, be on different papers, have different borders, etc. It's not just a single format, but rather a description of the ways various things can be compressed. That leaves us with mp4, the compression format. ![]() Now, that out of the way, we can ignore the first one, the container type, for the time being. Think of it as the poster from the first point it's been designed to be carried around in a mailing tube - but, for convenience, often gets carried around in something else like a generic folio case (e.g.avi. Secondly, there's the mp4 compression format.posters), but not things that don't (e.g. Think of it like a mailing tube you can put certain things in it that fit (e.g. Firstly, there's the container format ".mp4".There's 2 different things that get called mp4. ![]()
