Hi, I need to understand… if I edit a 3840x2160 (or other resolution) video and then save it with the preset: “lossless H.264” with: use hardware encoder, color gamut: full (jpeg), interpolation: Lanczos (best) In version 26.4.30, I get a video size of over 10 GB, while in version 22.12.21, the size is only 1.2 GB. Why does this happen? Are the settings the same? Has something changed in the lossless export mechanism between the versions? Extracting the frames from the two different saved videos and comparing them, no difference is noticeable. Sorry for the “Googled” translation. Thanks
In older versions you never would actually get lossless with hardware encoding because that was generally not available. You would just get something based on a request for the highest quality lossy. In a recent version, we added support for vtune=lossless on NVENC. You cannot usually visibly see the difference between visually-lossless (very high quality lossy) and truly lossless.
Thank you
