HDV adds 2 frames per minute when nested into DV
I know, I know, I’m cutting in the Devil’s codec….I know better, and I don’t care….for what I’m doing it works for me.
The questions is….For the show I work on, I cut all my sequences to 6 minutes in an HDV sequence, but when I nest the sequence into a DV sequence, 12 frames are added, every single time. No flash frames anywhere, just a consistant addition of 12 frames for every project I do.
Frame rate is the same, I just can’t figure out where the extra frames are coming from. Any ideas?

The 12 frames are messages from the video gods.
1) Don’t nest long GOP formats.
2) Don’t nest ever.

There are times to nest, and this isn’t one of those times. COPY/PASTE. Then render.

Again, instead of judging me for my work process, how about somebody provide an answer? Not all of us have the luxury of things like up-to-date software, capture cards, or properly configured computers (i.e. more than bare minimum RAM). My workflow, nor the need of why I do this when I need to, is not at question here.
Based on David’s comment, could the interpretation of the long GOP be the culprit?

I did suggest something.

Shane, I normally take high stock with your opinions or suggestions; in this instance though, that unsolicited suggestion includes re-keyframing about 35 photos and various other elements. Approximately 40% of the piece. 2 hours of additional work. ON THE OTHER HAND, i can nest the whole thing, render, and be done with it.
The question was not whether or not I should nest, but where I was getting the extra frames from once it was nested.
Turns out someone had unchecked the drop frame option at some time on another project, and it’s been carried over to a few other projects using identical sequence settings for a couple months now without notice.

You didn’t mention the keyframing issue. Is this solved, or can I offer another suggestion? Exporting a self contained file, then bringing that into the DV sequence.
But, it sounds like it is solved.
If you want GOOD suggestions, then please offer up the FULL details. Don’t shoot my idea down in a snooty way, as if I should have known that you have all that keyframing. How would I know?

12 frames, always 12 frames?
Could well be something to do with the GOP structure of HDV which as you probably know is a group of frames that requires the first and last frames of each group for reference.
In which case you’d have 2 options.
1) Follow Shane’s advice. (Change / convert it to a none GOP format).
2) Live with it, it’s the reason as you say its called the Devils format.
