Rendered movie crossfades when it shouldn't

I'm having a problem with the result of a movie. After it's rendered and I play it back(whether it's on the dvd or watching it on the computer) there are scenes that are cutting back and forth between the actors and they are now cross faded.

I diligently check to make sure all the cuts are flat with no cross fades, and checked again afterwards and in vegas it all looks fine, but when it's rendered, many scenes have cross fades when there should be no fade at all.

Has anyone else encountered this problem or have any ideas?

I've been searching the archives and have yet to find anything.
 
Are they fades or dissolves?

How long do they last?

What kind of footage is it? (Progressive, interlaced, etc.)

What kind of timeline is it?

How are you rendering it?

(Be as detailed as you can; just saying "I'm using AVIs" or "I'm rendering for DVD" isn't enough info.)
 
1. They aren't supposed to be fades at all, they're supposed to be straight cuts, but many portions are giving the cross fade effect after rendering.

2. It's about a 1 frame cross fade effect that it's giving and again, it's just supposed to be a straight cut with no fade.

3. It was shot with a DVX100b at 24fps advanced

4. We use vegas pro 8. When played on vegas you don't see the cross fades. You just see the straight cuts as they are supposed to be.

5. DVDA template for MPEG2
 
1) What I mean is, what is the effect you're seeing? Crossfades or dissolves? A crossfade goes to dark and then comes back. A cross-dissolve doesn't, it blends the clips together for the duration of the dissolve -- you can see both at full illumination.

2) OK.

3) OK.

4) But what kind of timeline? 60i? 24p?

5) Not 24p?

What I suspect is happening is that you're editing on a 60i timeline and rendering for DVD at 60i, and the frame interpolation is causing cross-dissolves.

Your better bet is to edit as 24p and output for DVD using the 24p DVD template.
 
1. Okay, i guess it's a cross dissolve(apparently i make up my own terminology) it's the kind where it never goes dark, it's like 2 frames overlapping.

4. We used the 24p timeline. We actually did it just like you showed in the video tutorial(THANKS!)

5. Yep, we used the 24p and used the 24p DVD template

. . . . It looks like we may have found the solution David. Maybe.
In continuing to search the archives, I found something that sounded somewhat similar to our problem and somebody suggested that they: Right click, go to properties and select "Disable Resampling" - so we disabled the resampling on each scene in the timeline.

So we decided to give that a whirl and rendered it again. This time after doing that and rendering, when we play the rendered version back on the computer, the cross dissolves are no longer there. So right now it's looking like that may have solved the problem.

We are about to put it on DVD and we'll see how it plays on a TV.

Regardless I'll write back with the results in case this actually does turn out to be a resolution and someone else has a similar problem.

Keep your fingers crossed, we'll see what happens!
 
Hmmm. That isn't behavior you should be seeing no matter what your resample method is, if you're using 24p footage from the DVX, editing in 24p, and outputting to 24p for DVD.

Is there anything you're doing to the footage when you make the DVD in DVD Architect? Are you putting in chapter markers or anything?

The reason I ask is because if you do, it'll cause the MPEG to be resampled, and under default settings, it'll be resampled as 29.97 and probably will cause the results you're seeing.

However, you can go, in DVD Architect, to File>Optimize DVD>Video 1, and under Recompress Settings, change the framerate to 23.976.
 
Here's the thing. We used all the 24p settings you mentioned. When we rendered the first time and burned to DVD (same settings) and popped the DVD in and watched it on TV, I started noticing these cross-dissolved about 15 minutes in. They were worse in some scenes than others.

I thought maybe we had compressed too much, so I re-rendered the whole thing (same settings), then, before putting it into DVDA, we watched some of the MPEG2 on the computer screen. We saw the same problems occuring, in the same places.

So we did the research, saw the stuff about resampling, and changed our settings. Re-rendered. Watched the MPEG2 on computer. Saw no problems. I can't explain why.

We're about to put the DVD together and render in DVDA. We will change those settings you suggested just to be on the safe side.

Any thoughts?
 
Just to conclude this story 4 months later, clicking on "Disable Resampling" seemed to solve the problem as everything worked fine from then on.
