View Full Version : info on vdub native noise reduction on capture

Hi there.

During my endless attempts at getting perfect captures with a relatively poor low spec system i noticed that i could use the noise reduction option in vdub's capture mode (under the video tab). Setting it to maximum caused ghosting in the caps, so i presume it must be some sort of temporal filter.

It would be nice to know which one it is exactly, as this may help me in deciding what the slider corresponds to. I know 'just use it and see if you like it' will be offered as a suggestion, but being able to put numbers on this by identifying the filter will speed this process. I also did a search but couldn't find anything specific.

Thanks.

** bump **

did anyone ever identify which filter this is specifically?

i tried this one last night as well and it does denoise very effectively on VHS

- it does look like a temporal filter (cause of ghosting when set too strong) but there are many more threshold gradients than "temporal smoother", which suggests it is not the same

anyone got the low-down?
