Change Aspect Ratio tag without full re-encode

[Jaydee]

Hello all, this is my first post.

I have recently leaned (the hard way) that there is an Aspect Ratio tag, or DAR Tag, inserted into a DVD mpeg2 stream during it's creation, (in my case, with TMPGEnc.). Unfortunately, I didn't know this, so changed the output seeting of TMPGenc to encode so taht it looked right on the PC. It was encoding in 720x576, and at a 16:9 ratio, leaving black bars (as I wanted) at top and bottom. But, I had selected a widescreen template, so, as far as i understand, this meant that it associated a 16:9 tag with this 16:9 film, in essence squashing it vertically again, after it had already been made 16:9. It looks fine on the pc, but in the player, looks squashed. I realise my mistake and I'm encoding my second movie te proper way.

But, I want to be able to change the encoded tag of the first one so that it looks right in my DVD player ( I will need to change it froma 16:9 to a 4:3) without having to re-encode the entire film, which takes about 3 and a half hours. Please help me, I hope there is a way.

yes - you can do this with pulldown.exe -- its in the tools section .. get the gui for it also .. just make sure you check off "do not perform pulldown" and just check the DAR change you want to make . there is no re-encoding .. and its very fast ..
