Please assist with Progressive / Interlaced settings

[f@chance]

After hours of search I only found one reference to finding out if an AVI file is either interlaced or progressive and it pointed the poster to the discussion on deinterlacing.

In order to set the quality parameters in CCE for either progressive or interlaced, how can I tell if the AVI video stream is either interlkaced or progressive?

Thanks for any help.

In my opinion, the best way is simply to single step through the video and look at it. If you find sections where there is combing in every frame (horizontal panning or action scenes will show it), it is probably interlaced.

If you can't find any combing, it is probably progessive.

If you find a consistent pattern of 2 combed, 3 not, 2 combed, 3 not, it is probably telecined and you'll probably be able to reconstruct the progressive frames by applying IVTC.

Beyond that it gets complicated. If you want to know more, your best bet is to read everything you can find on the net about interlacing and telecine, and just start experimenting with filters like decomb.

Thanks Kedirekin for your quick reply. All I am interested in is the settings in CCE progressive flag and ZigZag versus Alternat for Interlace. Since I will play it back on a TV I don't mind the Interlaced part at this point. However as I am building a collection and have a progressive scan DVD player, once I find a suitable progressive scan display it would be nice to have progressive streams.

However the whole IVTC and decomb part can be a headache and I am not sure if it is worth the time expenditure.

I like the quick indication in DVD2AVI and hoped that something like this also exists for AVI files.

Thansk again,
