![]() ![]() The negatives of upscaling video - it's slower, requires higher bitrate for certain level of quality Upscaling beforehand is only for the video. The upscaling algorithm does not affect the hardcoded sub directly, because the hardcoded subs will be applied at 1920x1080. Or maybe for anime you could use waifu2x, or anime4k or one of the GAN "AI" based methods You can use slower high scaling methods too if you wanted to. applying hardcoded sub at say 1920x1080Ģ) There are many threads and guides on "how to upscale". But the subs themselves will never look as good as when applied at the native playback resolution, because you're still scaling the rasterized low resolution subs vs. The benefit is the background video will look better too. "X:\Daves Folder\Sounds\VideoRedo Completed Sound Short.I understand but how do you do that? the subs are in an ass file so whatever it is better scaling methods or upscaled version as long as it's simple to do then it's fine.ġ) If you use a better playback scaling method, it will look "less bad." Maybe one of the madvr algorithms.
