16:9 footage changes when effects added

I'm using Vegas 6, and footage from an XL2, shot 24pA , 16:9. I'm in a 24P DV Widescreen project. When I do anything to a clip, add an effect, use pan/crop, etc., it changes the aspect ratio. Seems to become 4:3 (but letterboxed 4:3, not full screen), or at least it looks right when I use the 4:3 setting on my external monitor, whereas if I leave the external monitor in 16:9, it's like it becomes doubly squeezed, making it 2:35.1 .

What's the remedy?

No ideas?


So, adding a velocity envelope to a clip doesn't make it happen, but everything else does.

Doesn't even matter if you change anything, simply adding an effect changes the clip.

After you add an effect, go into PAN CROP and make sure it is still set at 16:9 - sounds like something is changing this. Do you have the properties of the timeline set to widescreen / 16:9?

I'll try checking it.


Yes, it's a "DV Widescreen 24P" (that's the name of the Vegas template) project.

Doesn't matter if I actually mess with the pan crop tool or a regular effect, changes the ratio either way.

Yeah, really weird. So it says "default" as the pan/crop setting once an effect is applied to a clip. No matter what setting I change it to, still looks doubly squeezed, vertically, on that particular clip.

What's happening is that before you add effects, it goes out to your monitor frame unrecompressed -- which means it's going out exactly as it is on the tape. If you watched the tape, it would look the same -- stretched up and down.

But when you add effects, it recompresses the frames, and the video goes out as 4:3 with black bars instead.

Thanks for the compliment on the shorts.


So you're saying it's not really altering the video, just the way it looks? That once it's on tape/DVD/whatever it'll be fine?

Ok, so if I go to options/preferences/preview device, and uncheck "recompress edited frames", it doesn't resqueeze it, but now I can't see the changes except on the Vegas preview window! You mean I can't see my changes on my external monitor unless it's super squeezed? That's whack.

No, it's not altering the video. It doesn't change in your preview on Vegas. That's what the video actually looks like on tape, if you were to play it FROM tape. It sends it through firewire exactly as-is.

If you uncheck that box, you won't be able to see any changes on your preview monitor, because Vegas won't be doing an on-the-fly recompression of the frames over firewire, so the changes won't carry over.

If it bothers you, do something which affects the footage, even if it's only temporary. I don't know -- slide the track fader bar down to 99% opacity or something. A slight effect like that won't really be noticeable, and it shouldn't slow down playback much at all.

Just to clarify, though--the aspect ratio changes I'm seeing AREN'T actually happening to the footage, just to the preview of it?
