compression question
I’m trying to export a video as quicktime file. It was shot on 16×9 (D1/DV PAL Widescreen 16:9 (1.422)). The project settings are the same and so the frame size (720 x 576). For some reason the .MOV file turns out to be squashed (it looks 4×3 to me but I could be wrong), although I made sure that in the Export Movie Settings the pixel aspect ratio and frame size match the project’s settings, but no luck so far.
Any idea would be appreciated -

PPro and Quicktime are not friends. Try using square pixels and adjusting the frame size accordingly to get a QT that plays back wide screen. QT sometimes does not read the pixel aspect ratio of files comming out PPro. I’d avoid QT altogether anyway and use H.264 (.mp4 files.) Still have to do the square pixel adjustment for QT to play them back properly though = but netter quality and higher compression. Don’t use the H.264 codec inside QT – strange things happen.

“Don’t use the H.264 codec inside QT – strange things happen.”
Huh? That’s seems to be a odd bit of unexplained general advice. Is that meant for PC users? On the mac we use quicktime h264 in a wide variety of shapes, sizes and frame rates every day with no problem. Couldn’t actually get by without it. Did you mean as an editing format? Care to elaborate.

On a PC since CS4. In fact, when you chose the h.265 codec inside of Quicktime (in encoder), you are warned not to do it. So I export H.265 directly as .mp4 files. Quicktime can play back .mp4 files just fine EXCEPT that it does not see the pixel aspect ratio – thus the square pixel requirement. I have forced Quicktime h.264s and interestingly they don’t preserve the pixel aspect ratio either. I have never used PPro on a mac, so I can’t help you there. On the PC, I think Quicktime is dead or dying. H.264 alone is as good and FLV/F4V is becoming the web standard for video. At least in PC land.

1) Buy Quicktime Pro ($30.)
2) Load clip into Quicktime Player. Go to Window>Show Movie Properties>Presentation.
3) Click the “Conform Apeture To:” box. The setting will change from “Classic” to “Clean Apeture”.
4) Save.
