Taking Neat Video to yet another level

Post by LeoB » Fri Mar 07, 2014 11:03 am

Hello, another matter often ignored when digitizing analog video sources are the picture edges.

When a VCR image is captured, the frame borders usually contain several pixels worth of redundant vertical and horizontal stripes at frame edge areas.

Now, when encoding captured AVI files into MPEG2 or 4 streams, you might have to use reduced video bit rates say 3 to 5 Mbits per second, to make the files fit into a single DVD, for instance.

As all such redundant frame content taxes the overall MPEG bit reservoir, thereby reducing the overall moving image quality (motion artifacts), it would be nice to have an easily manageable cropping tool for removing those frame border pixels prior to MPEG encoding.

Thank you for the suggestion.

The need for such a function is probably very important (in certain applications) but why should be a part of a noise filter?

Thank you,

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 the filter chain. That's where it belongs.

That has sod all to do with any filter, its all to do with the encoding settings.
