I video clip that I encoded to MPEG2 with TMPGEnc
I authored the file with sruceup and burned to DVD with Nero.

When I view at on my computer monitor I have black bars at the top and bottom of the screen. Which is ok I was expectting this.

However when viewed on a TV there is a black bar at the top of the screen ONLY.

1 Why?
2 How do I fix at so that that the black bars are even at both the top and bottom of the screen?

I have both full sceen/full screen (keeping aspect ratio) in TMPGEnc to no effect.

You might try changing that to 704x480 in "TMPGEnc"...

if I change it to 704 x 480 wont that mess up the fields for viewing on a TV? I was told not to resize interlanced stuff as it will not play right on a TV.....

But then that was in a script which I don't use any more...

But resizing in TMPGENc will be ok? As the output encoded file will be fine?

This sounds like overscan.

If the black bars are even when you play the video on the computer, this would indicate your TV has a larger overscan on the bottom. Computer monitors do not have overscan.

Can you try another television to test the overscan?


You could adjust the video for this TV using AviSynth, but it will result in uneven borders on the compter or another TV.
Crop(0, 8, 0, 0)
AddBorders(0, 0, 0, 8)
Increase the value if needed. (8, 12, 16, etc.)


I would not resize to 704 using TMPGEnc. You can try it, but I think you will find the results below.
- Resizing without "Keep Aspect Ratio" will keep the top and bottom borders exactly the same as they are now.
- Resizing with "Keep Aspect Ratio" will actually make the borders larger, and the interlace will be messed up since TMPGEnc will resize vertically to make the adjustment.

Am guessing I could use AviSynth to resize to get shoot of the blackbars/overscan and then rebuild the fields so that it all looks/plays ok on a TV?

Am new to al this though so am ot sure how or if ir is possible
