1. Forget to hit Record/Start Streaming
2. Stream gets shitty and starts dropping frames, stop streaming and resolve to upload later
3. Try to upload to Twitch, realize its uploader doesn't support .mkv files
4. Try to convert it with VLC, which doesn't work
5. Find out that OBS has a Remux Video option which lets you convert to MP4. That works.
6. Finally set to upload, watch porn
Watch Bayonetta 2 Part 2 from spoonshiro on www.twitch.tv
