I recently created a YouTube channel with the aim to post every single Doom TAS on dsdarchive.com. There's about 2,300 - 2,400 TAS demos to get through and I'm about 250 in so far, but more are coming! The unfortunate bottleneck is my monthly data limit preventing me from uploading more often.
All videos are posted in 4k 60fps. A small amount of demo smoothing is applied to mitigate slow-mo jitteriness and the sharp snappiness of many fully built demos. The red screen effect upon damage is disabled because some TAS runs take quite a bit of damage, including deliberate damage boosts, and I chose to prioritize being able to clearly see what is happening. Other screen colour effects from certain powerups are unchanged. Dsda-dooms advanced HUD is active and show a bit of extra info: current vs total kills, items collected, time taken, and secrets collected. Every video description includes a copy of the text file submitted by the TAS author alongside the demo and left exactly as-is, unless doing so was too big for the video description in which cases I've manually pruned them and stated this clearly. A download link to the demo file+original text file is included in every description, as well as a download link to the custom map pack if the TAS isn't for one of the official games. Where the creation date isn't mentioned in the text file, I've checked the creation date of the demo file itself and included this. Playlists are created arranging all the demos by their particular map pack and by their author.
It must be stated that Doom TASes do vary quite widely in quality, some are absolutely phenomenal and some fall short of non-TAS runs by a significant margin (to put it politely). While uploading I've made no attempt at distinguishing/ranking/rating them, but I'd happily point you to the "Movies" playlist for much of the really good stuff. Movies are any runs of more than 1 map, including full-game runs.
