What format is 1366 x 768?

I received a QuickTime H.264 file that's 1366 x 768.

That's not any format that I can see in Vegas's presets.

Does it have some reason for being such a size other than that some displays are that size natively?

Would it play back from a computer to a 1366 x 768 display pixel for pixel and thus with maximum quality?

Is there an advantage to working in that shape?

Your assumption about being that size to display natively on a 1366x768 display is probably correct.

If your graphics card in the computer can output 1366x768 and the display can deal with 1366x768 as an input resolution, then yes, it would probably look slightly better than the standard resolution of 1280x720.

Personally, I would work with it at 1280x720 to avoid any possible display problems down the road. 1366x768 is not one of the 18 ATSC standard formats.

One thing I have learned is that quality is kept highest if one works at the resolution of the source video.

When Vegas rescales to add or reduce the size by even a few pixels, the video goes soft.

Rescaling by a small amount is VERY difficult.

Rescaling by a lot is easier, and rescaling by an integer in each direction is the easiest (2x, etc.).

You could just try cropping instead of rescaling. Crop of the top and bottom 43 lines, then crop of the right and left 24 pixels. That would bring you down to 1280x720 with no scaling.
