I saw this run: https://www.speedrun.com/run/oy2kwwjy and I noticed it had no video proof, but instead had an image of the timer instead. I was wondering if this means that I could do the same, or if a need for video proof is just not needed in general.

If it is a reasonable time then it should be considered, however remember that that is a co-op run that is slower than the single player run, where co-op should within reason be able to be done faster than single. Unless you have proof of new routing methods faster than previous ones then an image probably won't be considered.

Thanks!
