After 30 hours processing...

Post by Lugarimo » Thu Mar 12, 2009 10:45 am

NeatVideo has done nothing. The videos in question are 120min footages with a somewhat variable gaussian noise. I made a profile as usual, with 85% rating and I selected 100 frames in virtualdub and the result was perfect, so thru avisynth with all the necessary cropping/resizing etc. I opened the video, applied the profile with a radius of 3 so it doesnt take too long and selected x264lossless for the codec. It took 15 hours each to process the videos and the result is a two 9GB AVI files that are EXACTLY THE SAME AS THE SOURCE VIDEOS. Well, they aren't, with careful examination of a couple screenshots I noticed that some pixels are very slightly brighter or darker, slightly less entropy.

What the hell is going on here? Right now, I think I must've made a mistake in configuration, because I was tired and desperate for sleep while I was setting it up to process overnight while I would be sleeping. Still, I never would be so irresponsible to make a mistake as dumb as that one to waste 30 hours. So tell me, is there any issue involving processing a large amount of data with NeatVideo with little RAM? I got 1GB but only 200-400 or so available at the time, and I set the priority on virtualdub for the first video to Lower and the other to Even Lower so the first one finishes first.

Now, before I try again, do tell me if I have done anything wrong the first time, or any more details you need, cuz I don't wanna waste another 30 hours for nothing.

Thanks!

I guess it made/makes sense to check the whole setup in Avisynth on a small clip first. Please try that now. The problem may be in your script, in codecs you use, in NV settings you give it, etc. Make a small clip work first, then render the whole thing.

I did do a test on one video, but before I made the avs script. I'll do that now.

Ok, I processed 100 frames and saved to an AVI and the noise was not present. The output pane on VirtualDub also confirmed it was working, and while processing the entire video again, the output pane confirmed the filter was in action. When I opened the 9 GB AVI and browsed to the 100000th frame where the scene of my 100-frame test clip was located, noise was present like last time and I wasted 15 hours again. What the hell am I doing wrong? Some problem with adaptive filtration or something? Ugh!

The Demo plug-in is limited to 30 min of footage as specified in the featuremap, so I guess you observe that limit in action.

AAAHHHHH, no f***ing wonder! I guess this is what I get when I don't read the readme. I will definitely set up a PayPal account soon so I can use NV freely. Thanks.
