TLDR - I would like to request the ability to view additional thumbnails containing the first and last non-black frame within a Comskip segment.
As we all know, Comskip is a best effort utility that occasionally needs some tweaking. The Edit Commercials UI has made it immensely easier to identify files that need a little TLC. However, I often find that the existing thumbnails do not show precisely where a "cut" took place.
Why is this important? I post process many of my DVR recordings. Using the generated .edl file, I remove commercials from these recordings. When I encounter .edl files containing inaccurate frame data, I manually edit the .edl files before I run my post-processing scripts. Thumbnails showing the first and last non-black frame within a Comskip segment will help identify which files may need a manual intervention.
