What is the source of the footage? Was it shot with a camcorder that had a telephoto adapter affixed? It coud be vignyetting (sp) where the adapter barrel is captured in the frames....

Hi RalphM,
Source was Canon GL2. I just noticed after capturing all the clips, that the shadows do not appear on every clip. All the clips look great on the camera's LCD, but some in Vegas have that "spot light" type effect. Any ideas??

I once used a canon wideangle lens and had the same problem. Now with a sony lens with my VX2000, the problem is gone. Just zoom in and out...do you see any dark areas at the corners ?

Hi jd555,
It's kinda weird because there's really no rhyme nor reason as to shots that have shadows and shots that don't. I have several shots (some zoomed and some not) and the shadows appear kind of at random. But they don't fade in or out on a clip...they're either on that entire clip or they're not. This is wierd in that I have been using this camera for a while with Vegas 5 and this is the first time this has come up...and I didn't do anything different on this shoot...

Are you currently using any adapters,tele or wide lens ? Remove them and do a test shoot.

How big are the shadows? If you view on an esternal monitor/TV are they evident? Not an explanation, but I notice that Vegas displays even more of the frame than I can see in the LCD of my VX2000 or on a well adjusted RGB monitor. Maybe they will not be a problem in the rendered output when viewed on a TV???

jd - no adapters or anything like on my GL2.

Ralph - they're really kinda small...they make the frame look almost "spot light-ish" (if that makes much sense).

I'll try a test rendor and see what happens...for now my brain is abit fried so I I think a beer is on order, and I'll start fresh tomorrow. Thank sto both you guys for the help. I'll let ya know what happens.

The Vegas preview window displays the entire frame. Many camera's LCD screens don't and even studio monitors unless switched to Underscan don't either.
Relying on the TVs masking is a formual for problems. Many LCD monitors display almost the entire frame so viewers using one will see almost what you see in the Vegas preview window. Take care of the entire frame. That's whay I now make the effort to cleanup crappy edges or anything, anywhere on the frame that could look bad.

As to you're camera problem. Two things will affect this. Lens focal length and aperture. The first is changed by you as you zoom in and out the second is controlled by the camera unless you're in manual. Most likely the problem will show itself when you are shooting wide at max aperture i.e. low light.
This isn't that uncommon a problem, even getting a lens hood unscrewed a few turns could cause it so do some test shots and don't rely on what you see in the view finder. Not only isn't it showing you the whole frame they don't have a high enough contrast ratio to really notice things like fall off over the frame. Just about anything look great in those little LCDs which is why they don't have them on pro cameras.
