Aut scene separation - Cineform Intermediates

Recently, I have mentioned here that we have found now a workflow, where we are able to run a automatic scene selection for some of the proxys, generated by Gearshift (so, DV-avi or mjpeg-avi material). That works fine, and is based on AV-cutty.

We have performed now some tests with the Cineform Intermediates directly (HDV 1080-50i). It works also fine for HDV 1080-60i.

Together with the developer of AV-Cutty, we have been able to modify AV-Cutty, and a first automatic scene separation has been successful, based on 1080-50i.

Is there an interest to use AV-Cutty for such a purpose? Feedback please!

Please be aware that the download version does not include that modification at the moment!

Does this make clean brakes in the video rather than leaving incorrect trailing and leading frames resulting from the GOP? This was my problem when I experimented with cutting. It needs remove a whole GOP secetion at the cross-over.

To my opinion, GOPs are available in nativ m2t material only - but not in Cineform Intermediates. That is a VfW avi codec, where you have no GOPs at all - but only compression within the frames. So, editing of Cineform should not be limited to any GOP structure. In my tests the scene detection worked fine - no issue from that side, even if I have to confirm that my test possiblilities are limited to the m2t materil from VASST.

But more: with the test m2t material from VASST, I also had no issue to make a hard cut in the video material, even not with Vegas-5. Vegas is able to handle mpegs too.

There is now a download Version of AV-Cutty available, where you can test that by yourself. Cineform Intermediates seems to work fine with that verison 2.4a, please test it yourself too.
