Using IVTC'ed MPEG-2 in Ulead DVD Workshop?

[ggladman]

hi all...first time posting, but i've learned a lot by reading your posts; thanks a lot.

i'm just starting to get the hang of IVTC (i hope)...right now i'm trying to get the cleanest possible capture and encoding of a movie to archive it to DVD. specifically, i'm taking my laserdisc of "The Wizard of Speed and Time" (definite 24fps material) capturing it in 720x480 with a Pinnacle DV500 in Premiere, frameserving to TMPGEnc and encoding to MPEG-2, and importing into Ulead DVD Workshop to author and burn.

whew.

my problem is this: i'm applying inverse telecine in TMPGEnc and getting what looks like excellent results. but when i load the .mpg into DWS, it seems to think the file duration is about 1h17m, rather than the 1h30m it really is. i suspect that DWS is being confused by the 24fps IVTC'ed video, and is treating it as if it were still 29fps. (the math seems about right.)

has anyone tried this, either successfully or unsuccessfully? i've finally got a combination of tools that works pretty well, so i'm hoping i don't have to drop the inverse telecine step to make it work.

thanks!

Never used TMPG to do IVTC. Decomb is my favorite IVTC tool. After IVTC, you have to apply 2:3 pulldown on your video stream to make it 29.97 fps and NTSC-DVD compliant.

you need to convert the 24fps mpeg into 30fps using a utility called pulldown.exe

don't worry, it will still be progressive, it just inserts RFF flags into the mpeg to make the player repeat fields, and it will make dvd workshop happy.

i think there's a way for tmpgenc to insert the RFF flags into the mpeg as it encodes, but I can't recall offhand which ones they are...

Thanks, that sounds like just the info I needed. I just shipped my video setup across the Atlantic, but as soon as I'm reunited with it, I'll give that a try.

Thanks!

I'm having the exact same problem you described at the beginning of this post regarding frameserving to TMPGEnc and having TMPGEnc IVTC the AVI before encoding. Everything looks good on my PC, but when played back on DVD after burning with DVD Workshop, it gets all out of sync because of the missing frames.

Was pulldown.exe all you needed? What did you do to resolve the issue? I thought that the "3:2 pulldown when playback" setting in TMPGEnc was supposed to put the flags in for you?

My assumption was that TMPGEnc did its job, but DVD Workshop then reencoded the file without the flags...

Thanks,
