You're sure ?
Jinc, Lanczos, ... are a part of MadVR and they deal with video filters.
These are scaling algorithms, they're not applying processing to the video as such. (no sharpness enhancements etc.)
The upcoming version of madVR will have the option to use debanding though, which is image processing that can smooth out gradients.
Hey, thanks for this explanation. Fills a knowledge gap.
To be clear, the quality of the hardware and software decoders should be the same with well mastered content. I have not encountered any problems with Blu-ray discs.
Well, I have
one in my collection where there might be an error with the hardware decoders, but I haven't investigated it fully - it may be a mastering problem.
But with TV recordings or poorly transcoded video, sometimes you might run into problems with macroblocking when using the hardware decoders.
I'm not sure what the source for this was (live TV?) but here's an example taken from a video that the hardware decoders show errors with, which someone posted on a forum a while ago - I keep a collection of sample videos that people have posted for testing things like this.
If you see problems like this where fast movement or flashing lights (this example had both) causes a lot of blocking/smearing of the image and you're using the hardware decoders, you may want to try using software decoding instead and see if it fixes things.
I rarely encounter this and prefer to leave hardware acceleration enabled so that high CPU usage does not interfere with playback.
I don't know how many pieces of IT documentation I've read that work along the lines of:Motherboard manuals come to mind. You're often not told how a feature works and what the pro's / con's of employing it are.
I know what you mean, that's very frustrating.
