Parameters to obtain more grain #552
Comments
Unfortunately, I found it difficult to keep the grains in NVENC encoding. --aq-temporal or simply increasing size might change but very difficult to avoid getting blurry. |
Hi, I found a solution. Much grain is kept with AQ spatial + AQ Strengh 15 for the same used bitrate. |
Yes, --aq-strength 15 is the strongest possible. I'm not sure with qvbr vs cqp, but generally cqp allows to follow temporal changes better, however bitrate spikes can occur and there is no control over the maximum bitrate. |
I have also tried many settings to try to maintain the grain of the video but without much result, what I was able to avoid a little was the blur. By deactivating the insertion of adaptive B frames and other parameters that affect the image such as temporal filters |
Hi, I'm new here. I'm using this encoder on staxrip 2.35. I have a video that has a certain bitrate and I need to re-encode it to permanently add forced subtitles. I tried CQP and QVBR mode, H.265 codec, Preset p7, output depth 8 and 10, both with and without AQ 0. Example paramenters :"--cqp 21 --codec h265 --preset P7 --output-depth 10 --aq" .I made sure to have the same bitrate as the source but the resulting file is a bit "blurry" which means it removes some grain. Are there any parameters that can help me? Thanks
