Hi Nat,
Thank you very much for taking my question. Your detailed explanation on "aspect ratio" is much appreciated. I am studying your response now.
>>>What does the sequence line look like with just the clip on it and no zoom, and what format of clip are you using?
Without the zoom, the sequence is perfect! It's only after I add the zoom that the black bars appear. I am using mpeg2. I also tried the same clip using .avi and it had the same issue (black bars).
>>>When you zoom in on the sequence do the bars remain on the thumbnails?
Good question. Let me give it a try.........Yes, the bars remain present even when utilizing the magnification and/or magnification scroll option located on the bottom right.
>>>Note that the images here are only thumbnails generated from the clip and the bars may simply be an artifact created by the VP software as the zoom is processed for the thumbnails but I have no idea only that I have never noted this in Version 2.41 or (so far) V3.02
Yes you are correct. When I save the movie (File > Save Movie). The resulting movie plays perfect and the zoom works as intended. It's just that most times I can't watch or see how the zoom effects are presented in the sequence window (when I click "play") because the black lines are present in one thumbnail (sometimes all) or they take on a new form (washed out thumbnail) as the new screenshot image below shows. But otherwise, the processed "zoom effect" plays perfect in the final "mixed down" movie file. Unfortunately I am flying blind during the editing process as I can only guess what the outcome will look like before the final mix-down.
>>>Do they appear in the preview in the right hand pane as the zoom progresses?
Yes. In fact, they appear everywhere! In the clip preview, track view and large sequence window. See photo below.
>>>If they don't then I wouldn't worry too much as its probably a bug. I would try a later version of the software.
I utilize Windows 2000 operating system for my desktop video editing. The reason simply being is that the OS is a work horse and I do simple editing. VideoPad ver. 2.20 was the last version that was supported for windows 2000. Also, my system utilizes "two" monitors using a matrox dual monitor video card. However the video card is not the issue as the black lines appear if I'm using either one monitor or two. VideoPad version 2.20 works great except for the black lines in the "zoom effect".
Also, I have been sending you "black and white" images of screenshots. Below is another black and white" screenshot and a "color" screen shot as well. As you can see in the color screenshot, the vertical lines appear as well. In fact, depending on where I set the "in" and "out" points (in the zoom effect), the image may disappear completely (in the thumbnails on timeline).
As you can see (in the color screenshot - below with "zoom effect"), playing the "preview sequence" shows me exactly what you see - pretty much nothing. As a result, it's very hard to get an idea of what the final output will look like until I save the final movie. However, if I save the final movie file (final mix-down), the zoom effect works perfectly.
If I remove the "zoom effect" everything functions as normal whether it is a color or black and white image/video clip (see color screenshot with zoom effect removed). I just won't know what it will look like until then. All "zoom effects" were set with aspect ratio set to "none". I did try the other "aspect ratio" settings and the results were the same (black vertical bars). See the screenshots below.
