[DCP-o-matic] anamorphic video

Hi Carl, I have received a video in AVI container, DV codec, so, pretty standard. However, it is anamorphic, so no square pixels. Various media players on my machine detect it properly as 16:9, but DCP-o-matic 1.76.7 detects it as 720x576 (1.25:1) and squeezes it when choosing 'no scale'. No big deal to correct this manually in the scaling options, but maybe you can fix that. Since the media players display it correctly, there must be a flag the DCP-o-matic currently ignores when analyzing it. The same happens when importing 16:9 VOBs from e.g. DVDs. Hmm, I understand that there is some interpretation necessary. DCP-o-matic first follows Default Scale To in prefs. While that is correct, and some options chosen have to result in wrong aspect ratio scaling, I think that at least the 'no scale/no stretch' options should follow the original content AR, if it is clearly indicated in the file metadata. At least the content description should indicate that the files is flagged 16:9/anamorphic. Aside from what the fact that in this case I can create a proper upscaled video - there is no way I could create an unscaled version of this file with the correct aspect ratio. When I choose 16:9, it get's uprezz'd, when I choose unscaled, I get a square 720/576 in a flat frame, when I choose NoStretch, I get a square 1350x1080. There is no way I can assign a 16:9 reference to this file. I think the proper way to handle this is to find a 16:9/non-square pixel flag in the file and act accordingly, that is, display it stretched and with a 16:9/anamorphic indication. I think that fight for all necessary yet straightfordward arranging of scaling options will never end... - Carsten
