why video size not full 720×480 (thin black bars on sides)
Hello
I’ve been using Vegas for over a year now but something keeps happening lately that I can’t understand, and I don’t think it used to happpen when I started using Vegas.
When I render my video with multiple tracks, the tracks that have graphics (e.g. gif or jpeg) on them that are 720×480 in size fill the entire 720×480 playback screen, but video tracks are not fully filling up the 720×480 playback screen, even though their properties inside the program show 720×480 in size and that’s the way I captured them from my digital8 camcorder via sony’s video capture right into my project media.
What results in the rendered video is a 720×480 playback frame which will be completely full when there are graphics that are of size 720×480, but when there is just video there is a blank space from the top to the bottom on each side of the screen which is about 5% to 10% of the width of the screen. I can’t tell if the edges of the actual video clip are cropped or if the clip is just getting “squeezed” horizontally.
I can usually resolve this by checking the box “stretch video to fill output frame size” but I don’t think this should be necessary, and may slightly alter the proportion of the actual video. I capture as full dv (avi files) and this is happening no matter what format I’m rendering (e.g. wmv, mpg).
It must be a global setting in the application or on the video tracks, or maybe something that isn’t working when I capture. I just can’t figure it out. I don’t think when I started using Vegas this was happening.
PLEASE HELP!

If the graphics are created in Pshop or other GFX editor, they should be created at 720 x 504 for correct fit, or 655 x 480. DV and MPEG are not square pixels, but your GFX editor is.

Even if I don’t have graphics there are still blank strips on each side of the video footage. I just mentioned the graphics to state that they seem to work corectly.

I have found that Vegas handles images really well. In some video editors you have to contend with square vs non-square pixels and change your pictures accordingly before you drop them onto the timeline. In Vegas I do the following on each image to make sure it looks good:
Put the image on the timeline.
Got to event Pan/Crop
Set “Maintain Aspect Ratio” and “Stretch to fill Frame” both to “yes”From there on all is well.

Then either the source, or the project isn’t set to DV. In other words, the source and project don’t match.
There is one other potential issue; it might be that you’ve got a black background and you’re mistaking the edges of the background as edges of the frame. Right click the window to change your background color to grey or white; see if that fixes your issue.Douglas Spotted Eagle

The source video may actually be 704×480. When placed in a 720×480 project there will be thin black bars on the sides.
Can you confirm if the black bars are not present in the source video? Also, try opening the source video in GSpot. It will display the actual resolution, pixel aspect and display aspect ratio of the file.

I am trying to make movies for viewing on computer only – not for TV or DVD. I am having your exact problem and I can’t figure it out. The funny thing is, the original captured AVI files do not show the black bars. I only get them when I render to WMV, with the ‘Stretch to fit’ option turned OFF.
When I turn the stretch option ON the WMV files do not have the black bars, but the image is subtly stretched out of proportion horizontally. I can tell because the lettering on my text frames is horizontally distorted.
If I render my video back to AVI there are no black bars on the sides. This implies that the original DV format is not the true proportions of the image. And maybe the WMV template is trying to correct that by compressing the width of the image to its true proportions. ????
So what gives? Which template will render a DV movie to its true proportions for computer viewing?
Thanks anyone!
