Injecting an I-Frame

[ron spencer]

You know I noticed that TMPG will let you force an I-Frame anywhere you like (good for chapter points). I am curious...does any other encoder support this. I looked at mainconcept's page and procoder's too and they do not seem to...this feature available with anyone else?

NuEnc can do it but only in command-line

Examples:
NuEnc -i G:\Trailer.avs -o G:\Trailer.m2v -maxbitrate 2520 -pass 2 -mpeg2 -vbr -hq -scene -gopsize 35 -forcekey ( 1 2 3 4 5 6 7 8 69 ) -keep -buffer 112 -turbo -rc_var 0.6 -dynamic

This will force frames 1-8 and 69 to be keyframes (note the spaces, they are important).

CCE will do that, you'll need to define the chapter list.
