Problems with cropping

Akina_Tanuki wrote on 8/27/2013, 5:47 AM
Hi,

I'm working in Vegas Movie Studio 12.0 and every time I crop a video track the unnecessary part doesn't just disappear - instead there is kind of a shadow on the place where the rest on the video used to be. So the bottom video track doesn't just shine through like it's supposed to - all the colors of the bottom video track are darker than they should be because of that shadow i can't get rid of.

If someone knows why this happens - I would be grateful for help.

Can you describe the tool and method you're using the crop this video?

Are the upper and lower video track just two separate tracks or have the been "parented"?

Is it possible to post a screen shot of your track motion (or pan/crop) screen including the keyframe timings? I wonder if you are highlighting the wrong keyframe track (and changing the wrong keyframe).

Actually, I'm just changing the width of the video.

No, they're just separate tracks.

Here's the screenshot.

The result always looks like that.

Oh, I just discovered it doesn't happen, if there isn't a coloring applied to the video. So maybe it has something to do with effects?

Not at all what I expected based on your description... :(

If you don't see it without the coloring applied, that might be it....Can you post a screen shot of the FX screen?

That is a nice chain of FX. I hate to ask for screen shots for all of them. Can you try unclicking each one, one-by-one and see if you can get rid of the dark shadow?

Nicely put, Markk, and a good suggestion.

I'm not 100% sure about this, but give it a try:

In your Video Effects window http://img196.imageshack.us/img196/5272/9r54.png click on the "Pan/Crop" box and drag it to the END of the fx chain.

I think the cropping cuts out the picture you want, but essentially leaves it on a "black" (with alpha = 0?) canvas shaped like your video frame. When you then start applying color curves and corrections to this image, it applies the effect to the whole frame -- not just the cutout. I think your effects are lifting your black and alpha (transparency) values above 0. But that's just my guess at it...

Apply all the fx to the whole image, then crop last, and I think it will work.

Yes, it worked! Thank you so much. The problem was caused by the gradient map and dragging the pan/crop box to the end solved it.

Thanks to all of you for helping.

Nice one Tim.
