Hi there
I have just finished a video project that needs to be shown in a presentation in 5 days, I have a major problem with it.

I created a picture frame (jpeg) to go around my footage (some footage from dv, some old vhs) ..the problem I have is that when I render to tape and view my work from my dv camcorder on the TV...I get some distortions around the edges of the frame...the frame around the footage kinks, waves and bends slightly on different scenes of my movie....I hope you understand what I mean and hope someone can give me the reason and a solutuon.

Thank you.

I'm not sure how you're adding the picture frame to your project, but if I was doing the same I would save the picture frame as a PNG or TGA with an alpha channel where the other footage is to show through. Then it can be dropped onto the topmost track and should provide a very clean border. I do this all the time with letterbox bars.

Don't panic, it's probably the TV!
Try to get hold of a decent video monitor or watch it on the cameras LCD screen. If it looks fine on either of those but wavy on the TV its the TVs fault.

I agree with farss, it's almost certainly the TV. On a lot of consumer TV's, the picture will shrink on bright scenes because their power supplies aren't well regulated. All the more reason to buy a professional monitor. You may just have your TV cranked up too hot, try turning down the contrast control. (It's never made any sense, but the "Contrast" control affects the brightness or maximum white level of the picture, while the "Brightness" control controls the black level.)

Be sure you rendered with the broadcast colors filter on. You could have scenes that are too bright for a TV.

thnak you all for the help...i ran a test on my tv, played the footage, and turned the contrast right down and like magic it fixed itself...but obviously like that it was too dark to see...my original footage was obviously too bright (old vhs)..I have applied filters to take it darker but has not helped too much...anyway you live and learn !

A lot of people run their TV's too bright and with too much color saturation. Go to the following link and calibrate your TV to reference color bars (which you can generate in Vegas) so you know exactly what you're seeing is correct with reference to the industry standards.

I made some posts on this exact issue some time ago.

I ended up just having to size it until it's not distorted anymore.

You may notice that the distortion varies dependent on the size of the frame.

...that is what I ended up having to do.
