Taking Neat Video to yet another level
Posted: 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.
