Re: Sequence Grabber - can it record at 'random' frame intervals?

Currently for example, if these kinds of delays occur, they are filtered out - such that all frames come one after the other, in sequence, with the same delay between all frames....

any way to do this? or do I have to record media into the QT movie manually?

Assuming this is related to your vdig questions, your vdig can do this by setting the frame timestamps returned by VDCompressDone() correctly.


QuickTime simply displays the frame at the correct time -- make sure you implement VDSetTimeBase() as well.

Also, one long-standing SG/QT -- if the TimeBaseRate of the TimeBase is non-zero and you return a duplicate TimeValue, QT will crash and/or generate a corrupt movie.

You need to drop the frame in your vdig in this case -- however during preview the TimeBaseRate will be Zero and all yout timestamps will be the same.
