Anyone willing to take a moment from a busy life to offer me a clue as to
what I'm doing wrong?
I've got an algorithm that works well for NTSC format DivX files and Cinema
format DivX files. If I try the same on PAL files, images are not properly
letterboxed on a 4:3 TV. I'm really at wits end.
For NTSC or Cinema, I take the DivX and blow it up to 720 x 480 using
VirtualDub. I like to avoid adding the borders. I simply tell the
transcoder to implement a 16:9 flag or a 2.21:1 flag (depending on the
aspect ratio of the source) and the resulting images are perfectly
letterboxed on a NTSC TV. Of course, if the source frame rate is 24, I use
pulldown and the drop frame flag while setting the framerate to 29.97. In
this way, I avoid adding the borders to the files, but, the DVD player
properly letterboxes the images on a 4:3 NTSC TV. Thought I really had
this thing down. But, then, came the PAL DivX and it's killing me.
I'm losing my mind trying to do the same thing to a PAL DivX.
WWW.VideoHelp.com and Doom9.org have been helpful, but, the tutorials there
always seem to incorporate adding borders to the files. Instead, I really
prefer commanding the chip in the DVD player to arrange the aspect ratio.
My DVD players are equipped to handle PAL. I'm going crazy trying to make
the DVD player display the proper aspect ratio using a PAL source DivX
transcoded to a PAL format DVD.
I have a 16:9 PAL DivX (25 fps). I blow it up to 720 x 576 with VirtualDub
and frame serve it to CCE 2.5 for transcoding while incorporating the 16:9
flag.
I burn it to DVD, pop it in the player, but, there's no letterboxing.
Geeesh! What am I doing wrong?
Thank you for anything you might have to offer.
