Now you have to re-encode everything again. At the same time you'll practice...)
Without adaptive quantization, the video loses details. Of course, the bitrate is reduced, but due to a very strong decrease in quality. I would advise using --aq in any case,...
Yes. But a fixed GOP makes sense to use with small GOP values: 12, 15, 24, 30... Better use Auto GOP.
Top one - with aq, bottom - without. Undoubtedly, the upper one is much closer to the original, details and noise are kept, I personally would leave the upper version.
30-50%. Then there's no point in storing 4K. By removing details and natural noise, you make the film - plastic. It's better to store 1080p, but encoded with HEVC and...
For 4K La La Land, the minimum possible bitrate is 27 Mbps, in order to maintain an acceptable detailing, IMHO. Try this command line: **NVEncC64.exe --avhw cuda --vbrhq 160000 --codec...
there is no limit to perfection ...) --avhw not the best way for HEVC, try avisynth decoder **NVEncC64.exe --vbrhq 160000 --codec h265 --preset quality --output-depth 10 --lookahead 32 --no-b-adapt --no-i-adapt...
LoadPlugin("L-SMASH-Works\LSMASHSource.dll") LWLibavVideoSource("La La Land.h265", format = "YUV420P8") Crop(0, 328, -0, -328)
avisynth decode original more accurately, so with all this parameters you'll get more 10% file size, but 20% file quality
