I think one piece of information I omitted is important. The segment in question, where the clouds are moving over the building, is not the beginning of the overall video. There is a scene preceding it.
See, I tried the “fade through black” transition and it caused the preceding scene to completely fade to a black screen before fading in the next one. While this did allow the building and sky to both fade in without the bleeding I saw earlier, it still is not exactly the look I need. It has that transitional black screen, hence the name “fade through black”…which could be fine in other places, but here I really just wanted the traditional crossfade. I also tried your other suggestions and the second one produced the same effect as the first. I couldn’t get the third suggestion to work.
Anyhow, your suggestion worked, in a sense: the building and sky both fade in and out without the bleeding. But, because it has that transitional black screen it doesn’t quite work in this situation.
Could it be that my workaround was the only to get that exact crossfade look I’m going for?

Well, here was my workaround.
Instead of trying to fade in those two still pictures at the same time, I simply rendered the segment (with no fades) as an m2t file. The result was a video clip that showed the building with clouds moving overhead…no fade in and no fade out.
Then, I inserted that video clip back into the timeline and applied fades to it at the beginning and ending. Rendering this time produces the clip with fades just like I wanted.
I prefer not to do that because I have this fear that every time I render video I am losing a bit of quality. Maybe this is an unfounded fear…I don’t know. Am I being too paranoid?

Steve,
I just tried the demo of Neat Video. You’re right, it’s pretty amazing!
-
Thanks, Steve. I downloaded that Image Restoration unit, but it didn’t have Noise Reduction in it. Did I make a mistake somewhere?
-
Yes, that’s the video I watched. But I can’t find the plug-in on the Boris website.

Well, it’s complicated.
The original project is interlaced 1) because the video was shot interlaced and 2) because certain pans across the still images are much smoother when interlaced (rendering as progressive causes some jittering).
It would obviously be easiest to render in SD from the original project, but the cropping gets messed up if I do that. The still pictures I am using no longer fill the screen; there are slight black edges on the left and right. The only way to solve that,as far as I can see, is to re-crop all the pictures.
There is one one final reason I need to nest. The original video has important things that are not in the safe area. By nesting, I can resize the entire thing to fit in the safe area.
Anyway, I tried your suggestion about making the original HD project progressive, and nesting it into a SD project also in progressive. All of the jaggedness is still there. So, I don’t know what the problem is, but it can’t be interlacing because there is no interlacing going on at this point.

The original video is 1440×1080 interlaced (upper field first). There are a handful of scenes shot with a Sony HD camera, but the video is comprised mostly of stills (to be technical, it’s comprised mostly of Photoshop files). These files are pretty large (generally about 5184×3456), BUT I have tried reducing the size of the pictures to about twice the project size and it made no difference in the choppiness of the video.
When Vegas prepared the video for the internet, it changed the aspect ration to 1920×1080 with a pixel size of 1.0 (I believe this is what YouTube prefers). It also deinterlaced it.
I have tried many solutions. Like I said, I’ve tried reducing the size of the pictures. I’ve tried rendering the video for YouTube using the MainConcept AVC – Internet 1080p template. I’ve tried rendering the video with a greatly reduced bit rate (CBR of 4,000,000). None of these things made a difference.
However, after watching other HD videos on YouTube, I noticed something. Whenever the camera pans in any of the videos I watched, there is the same stuttering that I see in my video. Obviously, this is a common problem. So my question is, can anything be done about it, or is that just a quirk of YouTube? Has anyone else in this forum noticed that pans get jittery when uploaded to YouTube?

Mike,
When you render to 720×480, what do you set the deinterlace method to?
-
Yes I always do progressive, as well, though I use 29.97 fps so the pans and zooms will be a bit smoother.
But as to the previous question, is there an acceptable amount of Moire effect? I assume so since I have seen it in professional video. Maybe I’m just being too picky; I do tend to be somewhat of a perfectionist. What is your opinion, J.F.?
-
I have used jpeg and png. However, usually I first edit the photos in Photoshop, so I just drop the Photoshop project files onto the timeline and Vegas uses them just fine.
I haven’t been able to detect any difference in quality between the different file types, honestly.
