[HELP] Does resizing a cropped resolution to a higher one cause video quality degradation?

[Bartoloni]

my 2 cents... better to not resize anything if the issue are 2-40 pixels lost... just use letterbox (and a correct PAR to make sure a decent player can handle and resize on the fly the clip... leave black borders to maintain a standard resolution .. ) resizing is just losing quality and details in a bad upscaling (for a bunch of pixels) .. and losing a lot of CPU time...

btw if you need to fill entirely the TV screen with an old PAL/NTSC footage .. risizing is necessary but it's BETTER to keep the original clip without resize for future editing purpouses.
