View Full Version : Best settings for High quality rendering without massive file sizes?

So I've finished my script ready to pipe it to ffpeg and render.
My question is, how do I get high quality renders without losing massive amounts of quality?

If you look at series on Netflix like Arcane or Blu-ray episodes of Tokyo Ghoul etc, each episode is 800MB-2GB max.
However they retain massive amounts of detail to the point of where film grain is extremely sharp.

However, the only way I am able to achieve the same levels of detail is Prores 422 at 2GB per minute of rendering (So 20GB+ for a 20min episode)
How can I achieve high detail at "low" sizes? Even at 40MB bit rate certain Blu-Ray's stay under 2GB per episode.

Just to be clear I am working on a series with 26 Episodes all around 20-24min. Currently they are rendering at 30MB bitrate for 1440p however again, file sizes just balloon if I want quality.



How do companies like Apple, Netflix and Anime studios get around this with their encodes? Would be a life saver to keep the 26 episodes under 60GB and not 200GB

Hmm Netflix quality is not that good. + Netflix uses VMAF metric to optimize file size / bitrate.

800-2GB of what video format? which resolution?
Have you tried a very slow preset and or tune grain in your encodes? What is your target video format?

2GB per anime HD episode is nothing special.

Depends on the content of the video, for example:
vspipe -c y4m script.vpy - | ffmpeg -hide_banner -i pipe: -c:v libx264 -crf 18 -preset slower -tune film -x264-params bframes=8:merange=32 video.mkv
If some parts get lost, try crf 16 or/and -tune grain
