I have a video I downloaded that has black borders on all 4 sides and I want to re encode with no borders. Does the Quicktime Player Pro have a crop filter?

I have QT Pro 7 and see no signs of a crop feature.

Bummer. It's just another one of those things that makes you wonder where the "Pro" in Quicktime Pro comes from.

Agreed. Most of the $30 features are hackable. Recording videos is cool, but I don't recall if that's Pro or standard.
 
Any progress?

Has anyone found a way to crop movies using a QuickTime filter? I have some that are 352x240, and I want to crop it to 320x240.
 
I've used the crop feature in ffmpegX with some success. Don't know if you wanted to stick with Quicktime only.
 
update to thread

With QuickTime Pro, you can assign a mask from Window -> Movie Properties -> click video track -> Visual Settings tab -> choose mask

Select an image of the same dimension as the movie, with a black box in the area you want to retain, the white borders will be cropped away. You can see a demonstration in this youtube video:

I hope I am not advertising here or anything. But I do this exact same thing with VisualHub which has a pretty good automatic cropping mechanism. It is $24 USD.

followup

I should add that I found an easier method for special cases (assuming only QT Pro, dedicated tools like previous post are probably more streamlined still).

During Export, if you use QuickTime Movie for the format, and click options, then click "Size", choose the target dimension, and then check "Preserve Aspect Ratio", and then "Crop" from the drop down, it will scale the movie to fill the image and then crop off what doesn't fit. (So for instance, choosing 640x480 on a 1280x720 image means it scales down to 480 high and then chops off the pillars to "pan-scan" HD 720P down to 4:3 SD ).

FYI, there's a similar size/aspect/crop sequence available if exporting to "raw" MPEG-4 instead of QuickTime Movie.

Of course, this only selects the middle of the image, the masking method lets you grab something off-center.
