Just when you thought…

…all of the technical issues were over… For those keeping score, I sent out my short to get the DigiBeta and HDCAM versions made, however, I figured I could easily do the miniDV tapes myself. In theory, it is a straight forward process. And it actually ended up being easy to get it on tape, but to get it to actually look right. That was another issue.

The short was rendered at 24fps, and of course miniDV is a 29.97fps format. The solution is to run the short through a 3:2 pulldown to change the frame rate. Much easier said then done. Initially I was downrezing each frame to 720×480 (with an anamorphic squeeze) and loading it up into Quicktime Pro and then outputting to an AVI DV format. It worked. Or at least it seemed to until I looked closer. Quicktime wasn’t really doing a 3:2, but just doubling up the fourth frame. This looked bad on any shots that had slow camera pans. You could see the stuttering.

I couldn’t successfully get QT to do a 3:2 the right way. So, after many hours of tests of potential solutions, I settled on using Shake to create a 3:2 pulldown and save to an AVI DV straight from Shake, bypassing QT altogether. Since this software does a proper pulldown, it eliminated the stuttering.
