A few questions on creating AVI's

[Sober]

After a few aborted attempts, Im finally ready to knuckle down and try and re-edit Superman II! But once again I have reached an obstacle before I have even begun!

One of the great things about Sony Vegas is the ability to retain a 5.1 soundtrack - a neccesity for me.

Anyway, I have extracted the footage from the DVD using DVD Decryptor and its left me with the AC3 audio and the M2V Video.

Now here comes the science bit...

When I come to create the AVI in TMPGENC, it shows my intended avi file as having an FPS of 29.97 and I set the video mode as 'interlaced'. But before I began transferring 31 m2v files to AVI I figured I better make 100% sure what I was doing was indeed correct.

So I loaded up the M2V File within DGIndex to see its properties.

Lo and behold it came up with the following:

Video Mode: Progressive
FPS - 23.976

Now I may be stating the obvious here but I need 100% clarifcation...does this mean that I need to create the avi using these settings? I would imagine that if I use 29fps, the audio will be out of synch.

I would be very grateful if someone could confirm this for me though...do I use these settings within TMPGENC and VEGAS when doing my project?

The source was encoded progressive at 23.976 fps, with 2:3 pulldown applied for 29.970 playback. Encode the avi at 23.976 progressive, edit, then encode back to mpeg2 (if that is your destination) again at 23.976 with 2:3 pulldown (your encoder should support this, but if not, use DGPulldown after encoding).

Many thanks for your help! Just to confirm...you are saying that i need to create the AVI using progressive with a frame rate of 23.976fps and then when I have finished editing it and the time has come to put it back on DVD...output it as 23.976 with 2:3 Pulldown?

Is this correct?

That is what I would do
