![]() I was just looking for a good encode of FMA:B on Nyaa, and ended up reading the same things you did about it actually being animated in 540p originally. The ffmpeg steps are acceptable, it's the upscale that is a real bottleneck. If you have experience with tools like these, do you have any ideas to speed this up? With my current setup (Ryzen 3900X and GTX 1080-ti) it takes about a day per episode. Has anyone else done something similar with their collection, and if so, how did you do it?ģ. What do you think of the upscale? Are there any consistent and noticeable artifacts?Ģ. (You have to download the file to actually see it well, the google drive preview uses lossy compression) It seems to work pretty well, I've included a sample of the first OP done with this process: Copy audio and tracks over with something like mkvtoolnix. ![]() \ffmpeg.exe -framerate 24000/1001 -i \upscaled_frames\d.png -c:v libx265 -crf 18 -preset slow -tune animation -pix_fmt yuv420p10le Upscale the frames with waifu2x-ncnn-vulkan -s 2 -j 2:4:4 -n 1 -i \original_frames -o \upscaled_frames.Convert your copy of the episode into frames with ffmpeg.exe -i -vf "scale=iw*.5:ih*.5:flags=neighbor" \original_frames\d.png (Since the original master is 540p we can scale down by 50% without really losing detail, in fact this is what is really getting rid off the jagged artifacts).Download and set up waifu2x and ffmpeg.This post might be a little long and technical, but any feedback is appreciated!Īs is well documented, the Brotherhood Blu-rays use an upscaled 1080p transfer of a 540p master ( Source) Given the size of current TVs and monitors, the jagged artifacts can be distracting, so I wondered if this could be improved with AI up-scaling.Īfter doing a little research, I found a wonderful tool: waifu2x, and so I made a little pipeline to upscale the series: The Heroic Legend of Arslan (Arslan Senki).My Hero Academia (Boku no Hero Academia).Subreddits for similar and recommended shows/manga, and for other works by Hiromu Arakawa Use the links below to view only posts in a particular flair category.
