"anamorphic flag"

[Mr Walker]

Is there anyway to get an "flag" for anamorphic picture on (S)VCD. So that the tv will get that signal to set the right AR-mode. (Signal is on pin 8 in a scart if I remember correctly).
Hope you know what I mean.

that would be a good app for some one to write if it doesnt exsist - to change the AR on any mpeg2 in the header with out re-encoding ..

[Mr Walker]

Hmm... or if it's possible during encoding, the important thing is if it's working/supported in any way.

[BJ_M]

during encoding its set by almost any mpeg encoder -- also with dvd's it can be set by some authoring programs as well

[Mr Walker]

How do i set TMPGEnc to do this when encoding a 2.35:1 or 16:9 movie.

[BJ_M]

its the relationship between ''source aspect ratio" and "aspect ratio" and "video arrage method" all found in settings .. for 16:9 (all versions of it from 1.77, 1.85 , on up to 2.11) use 16:9 in aspect ratio setting on output .. and adjsut other two as nessessary or letterbox if you wish using "clip frame" and "video arrage..."

"aspect ratio" is what sets the flag in the mpeg2 file ..

"source aspect ratio" determines the aspect ratio of the pixels (which can be manipulated to all sorts of ratios but generally .9:1 is what you would be using though its not marked that way - other programs can change this pixel ratio also before encoding).

"video arrage..." determines the placment of the image in either full screen or letterboxed or something inbetween ..

this is a simplified explanation...

[Mr Walker]

Ok thanx. So I guess this isn't working for VCD Mpeg1.
