Cropping and THEN effects?
Posted by Hamp Lund on April 4, 2012 at 10:48 amHello! I am wondering if there is a way to crop video and have the effects applied to the crop itself. The reason is to have effects that apply to the edges of the frame to be applied properly. Othewise the vignette for example is cropped out.

Could you clarify? I can’t seem to get any difference at all between cropping and trimming in this workflow, unless of course I’m not resizing the trim which I can’t believe he would be doing here.

April 4, 2012 at 1:42 pmActually I said it backwards, trimming the clip will not work, cropping the clip will work.
Here’s a clip that’s been trimmed.
Here’s the clip converted to a compound clip.
Here’s the clip with a simple border applied, easiest to see.
Compounds unfortunately don’t work as elegantly as nested sequences in this instance. Maybe I’m completely misunderstanding the problem, in which case, my apologies.
All the best,

April 4, 2012 at 1:44 pmI see what you’re saying. The OP was talking about vignetting which would work the way I suggested whether he was trimming or cropping.

April 4, 2012 at 2:08 pmAgain, that’s not what I’m seeing. Here the vignette is clearly more pronounced on the left and right, with no vignetting appearing at the top and bottom.
All the best,

April 4, 2012 at 3:36 pmSurely this is exactly what you’d expect since you’ve cropped (not trimmed) the image and not resized it to fit the frame. Cropping makes the image sit inside the frame – what you are seeing is the black bars top and bottom that you have chosen to put there, surely?
Your effects will obviously only affect the total image area and if that image area has black in it you’ll still see black. You’ve effectively composited your image over black so that’s what the effect will see.
Conversely here’s what happens if you use trim which of course fills the frame with your source image and hence leaves no black (once I’ve compounded the image and applied the effect – hard vignette and border applied):
And here’s what the image looks like before being compounded:

April 4, 2012 at 5:52 pmQuite right. My misunderstanding is the double use of the term crop in FCP. Shift-C is the Crop function, which has three separate meanings. In the trim function, which used to work with nested sequences because the sequence would adjust, compound clips do not work for this purpose unfortunately.
All the best,

You’re not kidding – it’s really hard for me to remember this new nomenclature. I have to refresh my understanding of Trim/Crop every single time. Somehow my brain can’t take in the notion that Crop now means “Crop plus Resize” to fit and Trim now means what Crop always used to mean. I even had to re-check before I typed that!
