Hello, I'm new to portal speedrunning and at the moment I'm trying to improve my time on the glitchless category.

I made a run with obs turned off but I recorded the demos: how can I watch the demos and record them with obs? Will LiveSplit work as if I'm actually playing?

I'd like to create a video proof of the run

Hello! Livesplit wouldnt work in this case, but that's ok, you can submit a run using the time from the demos. If you want to watch the run back, there is a tool in the resources section called the Startdemos Creator (as far as i'm aware it does not work for the steam version of the game if you happen to be using that). Follow the ReadMe file included in that tool and you should be able to play back the demos in one go and record it as well.

Thanks! It's working
