Lost frame when moving clips to subordinate timeline

[icreadence]

I have a video I am using for menus on a DVD. Since it loops the last frame is what a DVD will freeze on when going back to the beginning so it is important (and why I detected the problem).
The video has 8 DV files with moving paths and a color clip (pure) as the background (each clip is 12:00 seconds). I wanted to modify the audio as a whole so I created a new timeline with 9 tracks and cut/paste the video files (and color Clip) to the new timeline. Added this new timeline to the main timeline and found that at 11:29 there was a blank or black frame. This cause the menu to flash at the loop point.

The subordinate timeline is 12 seconds. The link comes into the main timeline at 12 seconds, only the last frame is blank. (I'm not sure what frame was dropped, the first, the last, or something in the middle, but there is a missing frame)

Has anyone seen this?

Hey from one MA guy to another. I had some spare time this afternoon and have been trying to duplicate your problem. Did pretty much what you said.. and rendered it out as one file then imported it into both DVD moviefactory and DVDit pro. It seemed to work fine in both cases.

More info: The file I created was a dv file. I usually let the authoring program make the mpeg file when it creates the iso. What file type are you creating? Could it be something seemingly trivial like the difference between a file rendered at 30fps and one at 29.97fps?

Also... In both programs I have the option of trimming the video and audio used in dvd menu videos. If you have a frame of black at the end... would it not be relatively simple to back up the out point one frame and not have to go through any of this?

I used msp8 sp1.

Let me know if any of this helps.

Non-linear editing is half art/half brain damage.

Thanks for the replay and investigation.
I was making AVIs in DV which I believe is 29.97 fps. I also did a DVD template MPG (IIRC is also 29.97). Both same results
My math shows that 12 Seconds is 359.64 (which should have resulted in 360 frames). This is close, but...
The issues are three fold.
1) the originals show up as 12 seconds. Only the main timeline and rendered video were 11:29
2) the loss of the last frame caused an awkward blank frame pause in the menu (Not normally a problem if I was just generating video since I would most likely have the last portion fade to black to make multiple videos transition seamlessly)
3) DVD Workshop only will accept motion menus of an integer number of seconds (any sub-second content gets cut off no mater what you do).

The workaround for now is to:
Add a frame of black in the beginning of the first menu then double the second menu and add a couple of freezed frames at the end of the second (this one loops).
This makes the first menu end exactly the way the second one starts and makes it an integer number of seconds. Now the second menu loops correctly.

This makes both transition/loop better.
