Unleashed's data files are already huge, so uploading (and downloading) it would be a huge pain already, for those with slower connections.
There's also the issue of legality. Keep in mind that this port is essentially aiming to deliver a fully playable copy of Sonic Unleashed, on the PC, for free. I know Sega's been pretty lax with the fangaming scene so far, but this might raise some flags.
Hopefully you guys can work something out. I've conceptualized a possible solution, but then quickly realized it wouldn't work for anyone with the PS3 edition of Unleashed.
Although if you really did want unsolicited constructive criticism, whatever editor you're using shouldn't frameblend, ghosting on top of the Hedgehog Engine's motion blur -> youtube encoding can make things look really bad (unless it's a 60->30fps folddown which is a completely different story, and 60fps at 1080p is pretty hard to achieve for outright video capture anyway)
That would explain a lot then why it looks so blurry that way! Since my original source videos do not have that affect at all. Thanks for letting me know, huge saver right there. I wouldn't have though Vegas does that re-sampling like that.
In Vegas, if you right-click on a clip, you have the option of disabling resampling. Resampling is the cause of the "blurry" effect of the videos it encodes.
Resampling is for situations in when the framerate of the source video is lower than the framerate of the Vegas project, then resampling will create in-between frames to fill in the "gaps."
