does your submission require gpu for evaluation (inflation)?

yes

did you include the compression script? and want it to be merged?

no

additional comments

In theory it should still run on CPU in <30 min. The submission name is kind of true but doesn't really encompass what the model does. At least its not a ffmpeg settings tweak.

On an unrelated note, I think the problem with challenges that also have open source submissions is that people are incentivized to not submit until the last minute to prevent other people from tweaking some tiny thing and surpassing their score. I kind of wanted to see some cool submissions, but I'm assuming the reason there's none yet is because they're saving all of their competitive submissions. I think <0.50 is pretty easily possible as a slightly different architecture gets a score at least 10% better, so there's definitely a lot of room to go. I minimally obfuscated the exact model architecture so people can't trivially spend more compute and clog up the leaderboards with exact clones to try to get prizes.

The idea behind open submissions is to speed run the progress. The prizes are just symbolic and fun incentives.
There is a point to be made about credit though, I will try to make that more visible in the leaderboard.
BTW you can get even better than 0.50 with this strategy and some tricks ;)

Just to double check is the video supposed to look like this?
