I've got all of my demos from my run and want to record them for my yt. I've done this with tf2 demos, using lawena. I'm 99% sure you can't use lawena with Portal. What's a good alternative for doing so? And does it have a queue option? (So I can add up all of my demos and record them)
use the command startmovie and run the demos using playdemo
This is a helpful guide i used when making a segmented run https://wiki.sourceruns.org/wiki/Source_Video_Creation
The only way to do it clean is to do what hat said. The clodo strat is that you record your game with OBS/XSplit/Mishira/Bandicam Playing many demos at a time isn't something I would recommend.
Inbounds runs that use Item Save Glitch to perform 02 skip will now be accepted to the leaderboards. Please provide demo proof for any such runs.
