actual video colour range (PC or TV) into log file
No passthrough hmmm...... I had a quick look to the manual. At the rear side you find socket 10 Video/Audio Output. Maybe the VHS signal is there with - if you are lucky - some line sync stabilization in effect which prevents flaggig. You could connect from socket 10 to a capture device (PC card or ...

actual video colour range (PC or TV) into log file
AFAIK all consumer DVD recorders record in YV12 (YCbCr) color format with TV range, i.e. the range for Y is 16 .... 235 (luma) and the range for Cb and Cr is 16 .... 240 (chroma). Black is YCbCr=(16,128,128) and White is (235,128,128). How the analog VHS tape is converted and scaled to this range de...

Re: DGDenoise
I noticed another oddity: It crashes when I load the script an run it the first time -> Access violation. Then I have to change any of the DGDenoise parameters and from then onwards it works. I had this before, but got so much used to this oddity that I just used it that way ... assuming it's on my ...

Re: DGDenoise
It's perfect now, thank you
And yes it would be great if you would include the 32 bit .dll in the official slipstream. I am still using much of 32 bit avisynth, so far.

Re: DGDenoise
DGDenoise introduces a slight color shift towards lower values in the histogram, for color=true. Also, some color artefacts appear at the very bottom and right side of the filtered picture, like a bar of few pixels. Is this to be expected, or is it on my system only? Script for testing, for example ...

Re: DGDenoise
Nice new feature :salute: Just nitpicking: strength=0 or cstrength=0 throw an error. In case one wants to denoise luma or chroma only, zero should perhaps be allowed to disable the unwanted function. Any plans to add temporal denoising? Now I have to do this in an extra step using a 'legacy' filter....

The user could also add black borders back after cropping. Do I get credit for this workaround?

[RESOLVED] PVBob() requiring mod8 height?
Hi, Maybe I am missing something, but PVBob (standalone) seems to require that the picture height must be mod8, otherwise the bobbed picture gets messed up. I didn't find the mod8 requirement in the documentation of DGDecodeNV, so maybe it is a driver issue on my side only. Any thoughts? Thanks. Win...

Re: DGDenoise as prefilter
As a general rule, should I use "strong" denoise parameters to use it as reference for motion compensated denoising? Not sure whether there is a general rule. Your source seems to be low contrast so that motion vectors may not detect details. Perhaps try to feed a clear and high contrast image as a...

Re: DGDemux development
Hi,
Would it make sense to add the language identifier to the 'xxxxx PID yyyy embedded.ac3' extracted core filename, like 'xxxxx PID yyyy embedded eng.ac3', for example ?
Convenient luxury, I know.

Re: DGDemux development
Thank you. I wasn't aware that DGDemux is also useful for HD blu-rays.
Here comes my first suggestion for the GUI:
A basic preview of the selected .mpls., or a crosslaunch of a player of choice (specified in an .ini, for example)

Re: Audio out of sync for iPhone 11 videos
High priority is to first try to find out why the device is not using a standard rate. Perhaps it can't keep up and you need to sacrifice something. Or, worst case, consider an encoding process that converts the 29.77 stream to 29.97. Is the video file reported as VFR rather than CFR? The .mp4 file...
