Re-aliasing video???

[progrocktv]

Hi all,
Recently I received a DVD of stuff that was shot originally in a studio on videotape. The person I received the disc from Deinterlaced all of the video before transferring to DVD, which completely KILLED the video look of the show (it now looks like it's shot on film, which REALLY pissed off my client I'm doing this project for). He no longer has the source tape, but is there any way to restore the "video look" to the production? My understanding is when this is done, several fields are dropped from the picture and it changes the frame rate making the image more jittery (which I can easily see whenever someone runs a video through Deinterlacing)

Thanks!

Several issues:

#1 Never toss the master. Backup everything at every step.

#2 Anti-aliasing is a filtering technique intended to smooth jaggie diagonals. It effectively trades image resolution for smoothedges. Not much to do with film look. It shouldn't affect frame rate. Something else must have been done.

#3 Frame rate conversion to 24p from a studio 60i shoot probably means deinterlacing and tossing good fields/frames. This process can be highly destructive to quality interlaced video. There are good ways to do this (30p with adaptive motion compensation*) and not so good ways. If done on a PC, it was probably the latter.

Not much can be done to reverse the process if the master was tossed.


* can't use 30p with standard DVD but it is allowed for DTV and HD/BD DVD.

Deinterlacing, that's what I meant. DUH! But yea, I was pretty mad when I found out he wiped the master tape! GRRRRR!
