KVCD: Borders problem
 
720x480 4:3 TV MPEG2 capture for 352x480 SKVCD.

When I enable GripBorders(), I cannot get TEMPGEnc to set aspect ratio (tried all combinations) and get borders on top and bottom of film with vertically compressed image on TMPGEnc screen.

With Gripcrop/Gripborders/Gripsize correctly setted, you set "center" in tmpgenc (or fullscreen) and everything is okay.

Now.. be carrefull that the default for Gripcrop is to handle the source as anamorphic ! If it is not the case for your source, you must put "source_anamorphic=false" in the gripcop line.

Else you will have a vertically streched picture as you report.

Will try anamorphic statements and set to "center" or "fullscreen". My problem is that the picture is compressed vertically, not streched, but I assume that this will fix it.

Your aid is appreciated, as usual.

Hi nicksteel,

Have you tried using the standard resizing given by MovieStacker, instead of using GripFit :?:

Forget my english. I was thinking "compressed" and I wrote "steched".

Gripcrop thinks your source is anamorphic (ie streched) so it compress it to restore the correct aspect ratio. The problem is that I guess your source isn't anamorphic, and does not need to be compressed. That's where your problem is.

Understand. Thanks Phil!

"source_anamorphic=false" cured my problems and then being able to use gripcrop() reduced my MPEG2 size.

:D Thanks, Phil!
