Problems Exporting 1920×1080 From HDV 1080i60
Posted by Eric Pautsch on March 13, 2009 at 7:58 pmHi Folks
I have a client who has an HDV 1080i60 1440×1080 timeline. My goal here is to export out a 1920×1080 29.97 8bit Uncompressed mov file. Once I look at the export there are several jump cuts throughout the program and audio goes out of sync – then goes back into sync. The times match.
I can’t seem to find out where the issue is here. The timeline is on a USB external drive and the export is going to another external USB 2.0 drive…could this be the issue?

March 13, 2009 at 8:16 pmWhy not transfer the proj. to a local drive and open – then export file to local drive and THEN, drop it onto whatever drive?

March 13, 2009 at 8:24 pmTry exporting with Export>Quicktime movie using “current settings” and see if you have the same issues. The resulting quicktime will indeed be 1920×1080 29.97. You can double check this by opening the mov in quicktime and hitting “command-i” to get the movie information. Unless 8-bit uncompressed is required, I would use this setting.
The USB drive probably isn’t the fastest place to store your media, but I don’t think it would cause sync issues.

You can’t playback an 8-bit HD file off anything short of a raid without dropping frames, much less a USB drive. It’s just that simple.

March 13, 2009 at 9:09 pmThanks guys! I’m not worried about playback but I can see those jump cuts as I slowing frame through the file I have so I know they are there. This is the second time around on this export. Thought the first time was just some hiccup. I’m at the client’s office who as no space left on his system. My thoughts were to export to a USB 2.0 and take it back to my place to encode.
This is to be encoded for Blu Ray so I need a 1920×1080 file uncompressed. If I export out as “current settings” wont the file still be HDV 1080i60 1440×1080??

March 13, 2009 at 10:13 pmOk…I’m a dumbass! The export needs to be 1920×1080 NDFTC, not 29.97. Thanks!

March 13, 2009 at 10:36 pmIf I were you, I would change the compressor in Sequence>>Settings to ProRes, re-render, then export a self contained QT using Quicktime Movie at current settings. The file will be ProRes, will export very fast, and although it will be anamorphic 1440×1080, that should not present an issue when encoding for BluRay.

March 13, 2009 at 10:41 pmThanks…Yeah….I thought of that but Im going to keep the status duo on blu ray 🙂 I think I only know of 2 titles that are 1440×1080. My new export looks fine now.

March 13, 2009 at 10:47 pmYou didn’t mention how you were planning to encode, but whether your QT is anamorphic or full raster should make no difference when encoding, it’s going to be 1920×1080 no matter what.

March 13, 2009 at 11:03 pmI know…call me crazy! I’ve never given a client a 1440 encode and I never will at this point. I’m using Cinevision for the encoding. 1440 is perfectly legal but I’ll stick with 1920×1080. Besides my menu designs will need to be different….Im a creature of habit. 🙂
