Ah, unfortunate, so I'll just grab the Twitch files, and if no Twitch files available the YT files, ok? I assume the YT vids are exported to YT from Twitch. Possibly you are not aware of this, with OBS you can stream to whatever platform and simultaneously record to HD in much better quality. The recorded better quality vid then can be uploaded to YT and to Twitch. Iirc Twitch Uploads are forever, unlike streams of unpartnered channels.
