Normally one would do that in an external editor. BTW - this is not only a problem with SD footage like from DVDs or DV-video - there are also HD-formats with non-square pixels, e.g. HD-DV/HDV is 1440/1080, and I just took a short test with my Sony digital camera set to MP4 format - it says '1080' in the camera menu, but in fact creates a 1440/1080 file with non-square pixels. DCP-o-matic states it is 1,33:1 and previews it squeezed. Now again, I can 'just' get it right in DCP-o-matic using the 16:9 option, but that is the only way to do it. Also - in this case I KNOW it is 16:9 and non-square pixels - what if people do not know it and/or the preview image doesn't give a clear visual indication? Personally I would love to have individual H/V scale sliders, but I don't think this is suitable for the general public ;-) I guess it would be best to make DCP-o-matic use an existing AR-flag. Then - checkbox or not..., in content tab, or prefs? I guess I would want to have this handled in content specific options, so a 'per file' setting. At some point it could become important with bitmap files as well, although they are usually easier to correct externally. I have seen quite a few files with non-square pixels WITHOUT a proper flag, but I have hardly ever seen a file with a 16:9 flag set wrongly, so I think the risc is small this will cause real harm. And I think most people would like to have DCP-o-matic show these common content types - DV/HDV, and 16:9 DVD with the correct aspect ratio after import immediately. Like my fellow projectionist does ;-) - Carsten _______________________________________________ DCPomatic mailing list DCPomatic(a)carlh.net http://main.carlh.net/cgi-bin/mailman/listinfo/dcpomatic
