Default thin blurry line at bottom of converted vhs tapes

I recently purchased a Canopus ADVC-300 to convert vhs tapes. I have tried a number of different vhs tapes (some old, some new) and wires (s-video and rca), and VCRs - and I always seem to get a thin blurry line at the very bottom of the video when it is showing and/or recording onto the computer. I have tried capturing in both iMovie and Final Cut Pro with the same results.

I tried capturing a DVD using the same method and there was no thin blurry line.

It doesn't show on a television since it's at the very bottom, but it will for digital videos.

Does anyone know what this is?

This is normal for analog recordings. There's often a lot of garbage around the edges of the frame. You don't see it on a normal TV because it's in the overscan area, but on a computer, it shows the entire video frame, including the overscan area, so you see it.

This always happens for me too. If you want to get rid of it because you will be showing the video on a computer, you will need to crop the fuzzy bit out during editing. Alternatively apply a slight zoom so it disappears off the bottom. Either way it will probably increase rendering time and may reduce quality a little.

I have "Analog Crop" presets that I use in both Procoder and Edius to get rid of all the fuzzy stuff that you might pick up during a capture from an analog source.

My preference is to trim about 4 lines top and bottom, and about 8 pixels left and right. I fill the area with black rather than scaling up the resulting image because I don't want to compromise it by scaling it up by a tiny fraction only to lose the borders to the overscan area again, and the black looks fine on both an underscaning display and a computer.
