nvenc available but lossless greyed out - petrus - 25.01.2025
Hi, first of all, thanks for developing your software, I really appreciate that.
I'm using Hybrid on my Windows 11 machine with NVidia RTX 2070 SUPER graphics card. I can select and use NVEnc for encoding, so that's fine.
When I want to create a lossless encode and set Encoding mode to "Constant quantizer", the lossless option still stays greyed out. Also selecting profile high444 and setting encoder preset encoder to Quality makes no difference.
NVEncC --check-features returns "Yes" for lossless. Am I doing something wrong or missing something? Please let me know if you need more info. Will add Logs-section of Hybrid and also NVEncC's output here.

RE: nvenc available but lossless greyed out - Selur - 25.01.2025
Can't reproduce this here. => try latest dev
RE: nvenc available but lossless greyed out - petrus - 25.01.2025
Thanks for your reply! After installing the dev-version I'm able to select lossless for NVEnc h265. For h264 it is still greyed out.
RE: nvenc available but lossless greyed out - Selur - 25.01.2025
I'll look at it.
RE: nvenc available but lossless greyed out - Selur - 25.01.2025
Think I fixed it, uploaded a new dev version.
You need to call 'Config->Tools->Clear all cached tool infos' after installing the new dev (or deinstall the previous version with all its settings).

Hi, I cleared the cache tool info and also re-installed Hybrid-dev version. This seems to be the same installer as earlier today?
It has no effect for NVEnc h264, it's checkbox for lossless is greyed-out
RE: nvenc available but lossless greyed out - Selur - 25.01.2025
Strange, did I maybe delete the new and kept the old upload,..
=> to be sure, I repackaged the version I wanted to upload (where lossless works fine here) and reuploaded it as Hybrid_dev_2025.01.25-183450.
