Hi - new user here. Is there a way to merge 2 videos together once they are saved on my desktop?
THANKS

Any video editor will do it, and you can tell it exactly *how* you want them merged too. OBS can do this too, with a scene for each video, and you switch scenes at the appropriate time. The tradeoff is that you lose a little bit of quality because it has to uncompress each one, do the merge, and then recompress the result. Each compression loses its own bit of quality.

Or if you *only* want to stick them together as if they were a single file that was erroneously split, there are tools that do that too. They can *only* stick them together end-to-end, fullscreen, because they're literally just concatenating the original bit-streams. But you don't lose any additional quality that way. Unfortunately, I wouldn't know what to google to find one; I only know that they exist and that's how they work.

Hi. How do I stitch together individual frames into one video. I recorded a powerpoint with each slide individually and now need to piece them all together (21 frames) into one video. Please help :) Thanks so much!

2 ways to do it:
  • Use a video editor, not OBS, to put all of the pictures on a timeline with the correct timing, transitions, and whatever else you want, and then export the video file from there.
  • Set up each picture as its own scene in OBS, with whatever transitions and other tools that you're going to need, rehearse it, and then "run the show", live in real time, while you record it.

If the recordings are the same resolution and frame-rate, you can join them together with mp4tools/mp4joiner. No re-encode required.
