Hi… I have seen a strange problem that was in some releases like 2.6.0 to 2.6.4. This problem is present in all the releases from 3.1.0 to 3.2.9, but non in 3.0.11.
The problem is the pulsing or flashing or ghosting of Dione Robust v4 dtd4 when you process a file.
These are the files for comparison
This is the original interlaced file
This is the file processed with 3.0.11 (this is ok, without pulsing problem)
This the file processed with 3.1.0 to 3.2.9 (this have the pulsing problem)
@gregory.maddra Please enable NVenc for HEVC with the slowest setting (-preset p7) and -tune hq, so it reaches the quality of x265!
This is the only reason I have to use the command line instead of the GUI… Now that one video can fully utilize the GPU, VRAM is not such an issue anymore. The video quality is much better that way and the encoder could do around 9 FPS anyway on an RTX 3060 TI with 8192x4320 while tvai_up processes at <1 fps, so it wouldn’t be a bottleneck.
This makes a big difference in archiving as 8K-360-3D-videos don’t have to be archived with >100 Mbit/s to prevent artifacts when encoded with preset p7.
Yes, the AI work itself does use both. But it only uses a lower quality encoding when encoding with the GPU, even though it wouldn’t slow down the encoding at all using a higher quality setting which is sad because the potential encoding processing power (seperate chip) is unused and higher bitrates have to be used instead which results in higher file sizes.
Yes, NVenc HEVC quality is pretty bad. Even the AMD GPU accelerated h265 encoding from the integrated GPU of my 7950X is noticeable better which is why I use it instead of the encoding of the 4090.
Actually, NVenc HEVC would be just as good as x265 when using the preset p7 and tune hq (I analyzed several frames thoroughly) but Topaz defaults to medium which is p3, which is sad because it wouldn’t slow down encoding at all anyway (seperate chip)… It would just use more VRAM (1-2 GB at 8K).
I am not seeing any pulsing on my end, is this noticeable on your end when played in the browser from the drive file? Or do you only see this when played with a specific media player?
Here the problem is very visible. Is something like, when it’s difficult for the software to reconstruct details, it will go blurring the entire scene.
