How to combine MP4 videos?

[KelliDrake]

Hello everyone! I'm a novice user so i'm still trying to figure things out every time using. But I'm actually stumped here. I wonder how I can combine MP4 videos. Can you show me how, please? I'd really appreciate your assistance.

Open the first video, then File menu/Append the second. The resolution must be the same.
If you want to use Copy mode, the codec settings must be the same, otherwise you have to re-encode.

I wonder how I can combine MP4 videos.

If you indeed mean "append", then you should also make sure that the number of audio tracks, the audio codec and codec settings, the sampling frequency and the number of channels for all audio tracks match perfectly as well.
