    Length difference of MC timeline and export

    Hello,

    I have a 29.97 1080 project. The length of my timeline is 1:23:50;28. However, when I export a quicktime reference, its length that I see using Cmd-I is 1:23:56. I render the QT reference using Sorenson, and the length I see (on Quicktime player, VLC) is 1:23:56. Why is the length different from the timeline?

    I sent this rendered file and an exported AAF to the sound designer, they see that it's in sync and the length is 1:23:56.

    Any explanation would really help.

    Re: Length difference of MC timeline and export

    Hey shayok,

    how many frames is your sequence? Maybe the 1:23:50,28 is not a 29,97 TC but rather a 30 fps TC. 1:23:50,28 on a 30 fps TC base would equal 150.928 frames. And that number of frames in 29,97 TC would be pretty much 1:23:56 in 29,97 TC.

    Maybe wrong display in Media Composer? Or maybe just some kind of wrong flag inside the Quicktime?

    Thanks Cutyes! I think you're exactly right. See screenshot: http://shayok.com/tmp/frame-rate.png

    I also see the frame numbers go 27, 28, 29, 0 as I scroll. Question is: how would it display as 29.97 fps? Is that even possible with the frame numbers?

    I believe it's 29.97, but in case I'm misunderstanding, could you please take a look at this screenshot: http://shayok.com/tmp/frame-rate.png

    Re: Length difference of MC timeline and export

    Since the separator in your time code is a colon, rather than a semi-colon, it indicates non-drop frame time code. This is a confusing relic of the past, but suffice it to say that changing the timeline to drop-frame time code (by making the separator a semi-colon), your timeline time should then be accurate to actual time. Go to the bin with your sequence and modify the time code start of the sequence by adding a semi-colon. See if this works.

    Apologies - please don't attach any meaning to the semi-colon. That's me typing. It doesn't appear anywhere on my Avid as far as I can tell: http://shayok.com/tmp/frame-rate.png

    Re: Length difference of MC timeline and export

    When I look at your screen shot, I see a colon separator in the Master Timecode window. This indicates non-drop frame time code, which will not be time accurate. In the bin with the sequence, modify the start time code of the sequence so that it shows a semicolon, rather than a colon. This should force it to drop-frame time code, which should give you time code that is time accurate.
