Re: PVBob() requiring mod8 height?

I don't see any obvious coding errors. It's really interesting. Crop only the sides: crop(0,4,-0,-8) # NO PROBLEM PVBob() Crop only the top/bottom: crop(16,0,-24,-0) # NO PROBLEM PVBob() Crop all around: crop(16,4,-24,-8) # FAILS PVBob() Here's the kicker. We can try to eliminate width/pitch issues...

Oh, right, sorry Bullwinkle. :oops:

In case you didn't know, the answer is 3. That's log base 2 of 8!

Do I get credit for a workaround? The user could crop after PVBob().
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...

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.

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) :scratch:

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...

Re: 3D BluRay

With DGDecNV you can only decode and index the 2D (='base') view. For 3D decoding you would need DGMVCSource. The DGMVCSource package includes the file 'DGMVCSource.txt' with avisynth script examples how to use it. See for example 'Return Half SBS conversion'. I would however advise to use and study...
