If you have doubts about your source stream, you can use a deinterlacer that can avoid touching progressive frames, such as FieldDeinterlace, TDeint, etc. CUVID hw deint isnt one of them? :( You wrote "etc." may I know what are the next? Yadif or LeakKernelDeint can avoid touching progressive frame...

My main interest are documentary, so it is more complicated here to say if it is interlaced or not.

You cannot inspect every single frame ;) Something about MBAFF: MBAFF, or Macroblock-Adaptive Frame/Field Coding, is a video encoding feature of MPEG-4 AVC that allows a single frame to be encoded partly progressive and partly interlaced. Maintaining the quality of interlaced video can be a challeng...

Be careful with deinterlacing as complete majority of TV (HD) and movie European 25 fps content is progressive (99.9%), docus often times as well or mix of both and only sport, music and live feeds are usually interlaced. As admin said, quick visual inspection tells you all. I dont agree. Here in C...

Hehe, thanks for the offer, but I dont want buy the source code :) Maybe you could release it as open source. Of course with removed regisration routines. ;) I dont expect any type of support. You just could make available this x64 version of DGAVCDecDI for download and say "use at your own risk, wi...

Simple recompile of the current source code to x64 isnt possible?

Is or will be DGDecIM able crop in 2px steps??

Hello, I am also interested in use x64 version of DGAVCDecDI. Do you plan release any newer 32bit or 64bit version of DGAVCDecDI ? I ask because sometimes I need to use computer without supported nvidia graphic card so DGAVCDecDI is the only choice. I would be very thankful, if it could be updated o...

What API from SDK should I discuss with them ? Which API is responsible for the cropping feature?

I know this. But I use private gui which support cutting over DGDecNV and it is very comfortable for me. Make cropping via Avisynth would crack my automated processing

I dont like loose more pixel lines of the picture than it is necessary ;) For example if only 1px should be removed I have to remove 4px, it is too much. With 2px step I would be much more satisfied. Also it will be easier to get better pixel aspect ratio error after resize if I will have smaller st...

Understand.

I would ask them but dont have any personal contact on any nvidia guy.

Also I am not sure how properly compile the question. I dont know their cuda sdk and dont uderstand what part is related to cropping limits... If you will help me build correctly the question I will ask them

So if any of upcoming drivers will change to support 2px cropping you will add it, right?

Did you try ask nVidia guys why they have set limit to 4px cropping step? Do you think it is any kind of hardware architecture limit?

Hello Donald,

may I know why DGDecNV can cut only in 4px steps? AviSynth support 2px and even 1px if I am correct. Would be big problem to modify DGDecNV to support 2px cropping step ?

Thanks for reply!
