I'm amazed that it's so simple to implement and NVIDIA would allow something like that. If I'm honest, I thought they'd lock you to their PureVideo de-interlacer.

On a separate note, don't you have an FTP people can post to, or am I thinking of someone else?

So a word of warning to Vista users - don't use the two DLLs supplied in the package (nvapi.dll and ncuda.dll) as I think they are from Winxp and must be different to the Vista ones (which are already in system32). Looks like nvcuvid.dll is still needed.
There is simple solution : if OS=6.0 then use system32dlls else use dlls in main direcory

what the hell is going on

i test the new version with some orf hd test file (1280x720 50P)

First Pass: encoded 3618 frames, 19.61 fps, 4972.53 kb/s
Second Pass: encoded 3618 frames, 87.28 fps, 4994.29 kb/s

i used these settings:

Code:
x264.exe --pass 1 --bitrate 5000 --stats ".stats" --level 4.1 --bframes 3 --b-adapt 2 --direct auto --filter -1:-1 --subme 2 --partitions none --vbv-bufsize 50000 --vbv-maxrate 50000 --me dia --threads auto --thread-input --progress --no-psnr --no-ssim --output NUL "dga.avs"
pause 
x264.exe --pass 2 --bitrate 5000 --stats ".stats" --level 4.1 --bframes 3 --b-adapt 2 --direct auto --filter -1:-1 --subme 2 --partitions none --vbv-bufsize 50000 --vbv-maxrate 50000 --threads auto --thread-input --progress --no-psnr --no-ssim --output "video.mp4" "dga.avs" 
pause
can't belive it, but the encoded video works fine here

Your first pass is slower because of frame decision, second pass does not have to do this and is much faster because of your lowered quality settings.

You should maybe ask one of the x264 developers about this then, I looked at your settings and they are almost indentical for both passes, except for --me hex on second pass.

Simple : you're using --b-adapt 2, which is much slower in the first pass than on the second (since it does all it's magic in the first pass).

First time I've ever had a complaint that my software is too fast.

I am very happy to report that everything works flawlessly as far as I can find (flawlessly for my workflow anyway). Here's how it goes:

1. Process an M2TS file from a ripped blu-ray (in this case, The Girl Who Leapt Through Time) through DGAVCIndexNV
2. Create an AVS script to process the .dga
3. Open up my Premiere project that uses an MJPEG encode of the movie (made from the blu-ray, originally using the old DGAVCIndex
4. Replace the footage with the new AVS script
5. Everything is in it's right place and works perfectly (granted it's slow, but I mean, it's 1080p. I would never expect it to be)

I can export from Premiere in full 1080p and everything works great. What I had to do before was demux the m2ts file to a .h264 file, process that through DGAVCIndex, and then bring that into VDub to encode it to both MJPEG and to Lagarith (resulting in an enormous file, and the encode time was very significant), and then bait and switch between the two.

So basically, having this new workflow is going to save me a ton of HD space and a lot of time. Thanks a ton!

My #1 request: Linux support. There is CUDA for Linux. If any Linux devs are willing to help neuron2, then, since I don't believe he uses Linux at all?

Neuron2 - Will you add simple support for .MKV?
It would be great if I could import mkv generated by eac3to directly without demuxing.

Unfortunately Cuda Linux SDK doesn't contain the necessary video decoding functions, probably because the display driver doesn't support VP2 in any way.
