Exporting 960×720 Timeline to Video
Hi, I’ve been struggling to output an HVX200 shot video file (960×720) into a different resolution: 480×320 letterboxed. I not only don’t know how to do that, I don’t know how to get the file to look normal, without stretching. I’ve outputed from what feels like every possible way with the H264 compression.
I realize this has something to do with the square vs HD pixel issue. My questions is:
How do I output a correctly sized, letterboxed quicktime video from a 960×720 timeline?

Drop your HD sequence into a SD sequence and it will letterbox itself. Render that, and then exort via compressor or QT conversion to 320×240.

Oops, you said 480×320. What’s with that? That is neither 4:3 or 16:9.

Hi Bret, thanks for your response. Its a weird format I know. I just want it to be that way for a particular website. 480×320. Is it possible?

I tried it. It didn’t work. The image won’t fit a square pixel frame like NTSC. It is stretched vertically. I need a different method.

Since 480×320 isn’t a standard resolution, you’ll have to crop it while exporting. Compressor has the option to add a crop filter while exporting, but you might find it easier to use MPEG Streamclip. Just feed it the original Quicktime, select your resolution and select the “crop” option, and decide how much you’re going to crop from the sides.
How much to crop? Well, let’s see: the HVX-200 footage is 16:9 or 1.777, while 480×320 is 1.5. Therefore, a movie with 320px height and 16:9 aspect ratio should have 568px of width. You want 480px of width instead, so… well, now you know how much you should crop.
