Firstly. WebNations is a hack that profited off everyone's work. That account can stay dead.
With what you stated there are issues with how the person dumps their videos for their commentary that wouldn't line up with our dumps/encodes as they do things differently
which causes a/v to desync on our end (author commentary isn't lost to time, a backup of it exists), or they present it differently with pausing and whatnot (as you mentioned).
That's why we usually point to their encodes on their personal channels instead of providing ourselves. We would have to put in guidelines and a
request for how the author has to present their audio in advance to their submission if we want to do it cleanly.
Certain authors also stylize their work, so there's that as well.
Another thing we're waiting on to hit TASVideosChannel as seen on
Netflix Anime for instance is multi-track audio.
This will help reduce the amount of Sonic CD encodes for instance (different soundtracks), and allow split audio tracks in multi-game encodes such as the recently published
Pokémon coop diploma. But again it can land on the a/v desync issue.
A better method to showcase these, rather than bury them in the mass of encodes (and classify it as ours, even though it's their hard work) is to actually have a playlist that goes off to the author's YouTube, a highlight sort of thing.
The author created their commentary, so they should be the one to have their encode featured to their channel not ours.
I personally rather not steal off of others commentary like another hack that previously existed.
