This is a likely a pixel aspect ratio mismatch between your
project and the footage you have captured. Try setting the
pixel aspect ratio, frame size, and frame rate of the VF
project so that they are the same as your source material.

I'd start with project settings of 640x480 with a PAR of
1.0.

Thanks Sonic,

Per your suggestion, I went to Video Factory, Files Menu,
Preferences and tried various combination of frame size,
frame rate and pixel aspect ratio. I would get different
shapes for the black preview window, but the displayed
video was unchanged, still taller than it was wide and only
filling a portion of the preview window with black bands on
the side(The source is 8mm video that is wider than it is
tall, like TV).

If I preview the captured video in Sonic Foundry Video
Capture it is also taller than wide even though it displays
correctly (wider than tall) during the capture process.
Since the symptom is already present in Video Capture, is
that the place where the correction is needed?

Thanks again.

that's possible. there are allowabe resolutions like 352x480 that are 'taller than wide'. before you encode, right
click on the video stream and uncheck "keep aspect ratio". then it will be able to scale to project size. in
capture, check the resolution you're capturing under 'format'

Lets back up: you are capturing at what size? with what
card? if its an MJPEG card (sounds like it is) then during
setup for capture you'll be able to access most of the file
size info and adjust it if you want.

Other option: load the file on the VF timeline, right click
on the video event- you'll have a display of the media
settings which should be correct. It is possible that the
pixel aspect will have to be set, and saved, so post the
file size and data here and I'll keep my antennae up-

Wow! You guys are good. Thank you for your quick and
helpful advice.

I still think the Sonic Foundry Video Capture program
introduces the “taller than wide” problem but I can now
correct for it in Video Factory.

If I play a captured clip in a third party program like the
Microsoft Windows Media Player or the ATI file player it is
taller than it is wide. This is why I think that the
source of the problem is in Video Capture.

However, per your suggestion I can open the clip in Video
Factory, then right click on the video stream in the
project window, then click properties, then uncheck Keep
Aspect Ratio. Then go to the file menu, click properties,
then set height and width. The displayed clip will now
respond accordingly. By the way, what are the correct
values to enter here? During capture a note in a window in
Video Capture says 320X480, 29.97 fps, Microsoft YUV.

Per Sonic’s questions about hardware. My video source is
an old Sony Hi8 video camcorder. My video card is an ATI
All-in-Wonder Radeon. My sound card is a Soundblaster
5.1. The video is plugged into the video card with an S
video connector. For every other application I was able to
plug the video card sound output into the sound card line
in. I don’t know why, but for Sonic Foundry I had to plug
the sound directly into the sound card instead. I have two
hard drives so I capture to a dedicated 40 gb, 7200 rpm
drive.

Thanks again.

320x240 is a good resolution to capture at if you are
creating streaming media or making videos for CDs.

Since you are capturing at 320x240, most likely the pixel
aspect of the footage is 1.0. I would set my VF project to
320x240 (use the mutlimedia template but change the frame
rate to 29.97.

Confirm that the project pixel aspect is 1.0 and you
shouldn't have to adjust anything in the event properties.
