Upscale

Postby Tsiahiv » Fri Jan 29, 2016 2:32 am

Wanted to upscale some footage from 480 to 720. Is it worth it? I tried to use l33tmeatwad's upscale script, but I can't really tell the difference or If I put it on correctly to begin with.

that's good. If you can't tell the difference then it looks good either way right ? :ying:

I don't know. What looks better ?

here is an example of what I work on currently:

it highly depends on what your intentions are, like what do you want to accomplish with the video ?
Does it look good in most scenes upscaled ? some scenes might look worse than others, some details are not meant to be upscaled and can look worse ...

Thanks. Yeah I was trying to upscale some Bleach and Naruto for some projects later on this year. Half the shows are in 480 and the other half is in 720p so it makes it a bit strange in terms of coherence. You're editing hentai? Lmaooo. I don't think it's possible to avoid the artifacts at this point.

yeah in this case it might be hard to avoid upscaling ...

Yes I do :awesome: In fact I just recently announced like 3 together (NSFW)

yeah some artifacts might remain. Be sure to try out some spatial denoiser. I'd suggest using KNLMeansCL it worked well for me so far.

Just a comment on the sources specifically, Naruto and Bleach in the early seasons when it was animated in SD tended to have a lot of light colored/blurry lines and neither source really upscales that great. My script works better with digitally animated shows that tend to have more defined lines and with older cel animated sources that don't have much grain/noise.
