Sorry this reply is so late, hopefully you figured this out already but I wanted to reply so that people didn't end up confused by what they were seeing vs what you reported. Your clip is either Interlaced. Or Possibly a mix of Interlaced + Telecine as well. I found that out with 5 minutes of playin...

Have to agree, I don't see what this has to do with noise filtering at all. Unless you actually mean to imply NV arbitrarily treat such frame edges as noise, which is a horrible idea. Cropping is a basic process that could be done in pretty much any video application, long before it reaches NV in th...

Topic: Why is there banding in video after noise removed
Replies: 2

You can eliminate most banding by leaving your videos RGB, or possibly another 4:4:4 format (YV24?) Otherwise the only way to mask it is to add noise back in to the clip like has been mentioned. A good playback engine can actually handle banding pretty well if setup correctly, since videos are conve...

The first thing I noticed was - the wall is not black. It is brown? Also, this looks like a case of color banding. Which usually happens when converting from a higher chroma subsampling to a lower one (i.e RGB -> YV12) What was the source input format (I'm guessing RGB), and what was the output form...

I can understand this to a certain extend. But at the same time, I still have a hard time "accepting" such low numbers compared to what NV reports. Its interesting you bring up the filter chain. I can save out with no filters, to a lossless file (I decided it was better to do this than to ...

Random thoughts, trials & tribulations: rendering speed

This initially started as a question about how the benchmark stats are calculated.. But I expanded on it just by sharing my own experiences and there may be a question or two scattered amongst the wall of text this post turned into... I'm not necessarily complaining or anything, as I'm just kind of...

Take note if you are also rendering directly out to H.264/AVC then that will likely also drastically reduce your speed. encoding eats a lot of CPU, especially when encoding in HD. I always render to a lossless intermediate file, and then encode that file with x264. My renders through Vdub usually ta...

Yes, I've fiddled with auto complete before. I've also tried to use Auto-Fine Tune, but can't make sense of the thing. The profile will jump up and down all over the graph and in some cases previous samples become undone and revert to yellow/missing. Which doesn't quite make sense to me given the wa...

Well its not rocket science, exactly. The key to building a good profile is time and patience. In my case it becomes a cumbersome job because I tend to work with Episodic content (mostly Anime) like TV series and I am working on multiple files in one go. So its kind of a time sink to have to manuall...

I have a follow up question. I haven't done a lot of filtering / encoding work since my initial appearance here but I am getting back in to it, with a current project (a new Anime BD set I picked up). I have noticed with this series in particular, I have a lot of trouble filling in the first R/G/B a...

Why not add some simple logic to test for a boolean that will enabled/disable all filtering? You could have a GUI checkbox option "Disable all Instances of Neatvideo Temporarily". I know I say this without knowing your internal code structure, but you could encapsulate the filtering logic ...

The only way I could see to improve that, since you have to open the filters tab in Vdub, and then select NV, would be to just get rid of that initial dialogue box, and put everything into a tabbed main window that opens from the filter selection box. Having it remember the last tab you had opened a...
