ok i have a source 640x360=16:9??
im trying to resize it to fit 704x480

MemCalc suggests:
resize to: 704x360 no crop

meanwhile moviestacker suggests:
cropto: 624x352
resizeto: 704x352
w/ ERROR 0.03%

or

cropto: 528x352
resizeto: 704x416
w/ ERROR 0.03%

and MemcoderME (no script) suggests:
resizeto: 704x356

all three programs suggest different things, which is most accurate?

in some instances the final resize will be +64 horizontally, and -x vertically...even though it 'sounds' like its stretching it, that's ok right? because i read: http://www.kvcd.net/forum/viewtopic.php?t=10410

"Every 720x480,704x480,352x480 MEPG with a 4:3 Aspect Ratio flag will be resized in real-time to 640x480 when playing back."

and how do i know what i should use for output aspect ratio? when should i use 16:9? 4:3? does it depend on your tv, source, or both? because i tried with 16:9 and it looks really stretched with vlc, but looks normal in wmp

We are in private discussion with Incredible on this point. You can just wait us to finish or I can send you the 10 pages long message he sent to me yesterday and I don't read the third yet ))

Stay tuned !

Hi silverspoonjackass,

Welcome to the world of aspect ratios

Take a look here: www.uwasa.fi/~f76998/video/conversion

Or for a more simpler explanation, read this, which is very good: http://www.arachnotron.nl/videocap/d..._cap_v1_en.pdf
