I goofed! Encoded TFF AVI to MPEG-2 as BFF

[bigdog660]

Back when I didn't have a clue, I capped some video through a Hauppauge WinTV-GO Capture Card. I then encoded the video to MPEG-2, Authored it, and burned it to a DVD.

When I encoded to MPEG-2, the default option was Bottom Field First, and like the noob I was, I just left it and never tested it.

Only after I converted about 20 of my Laserdiscs to DVD did I find out what I did wrong. I should of used Top Field First.:eek: You can imagine what any fast motion looks like!

My question is this: Is there ANY way I could fix this? I just guessing but maybe IVTC would fix the problem? Some sort of AVS script with decimate? Obviously, if I can fix the problem, I'd have to re-encode, and at this point I'll probably encode to Xvid, and would like to have 24fps anyway.

I still have the laserdiscs, but unfortunately, I don't have a player anymore.

Any ideas would be appreciated.:thanks:

demux the DVD into video and audio. (DGindex or PGCDemux can do that)
grab restream
open the m2v in restream.
set the flieldorder to TFF
save as m2v again
author a new DVD with fixed m2v and original audio.

this way is lossless regarding the mpeg2-structur. but ancoding however was sub-optimal due to wrong field order to start with.

Thanks scharfis_brain, I follow you perfectly except when you said

but ancoding however was sub-optimal due to wrong field order to start with.

I understand you said correcting the field order is lossless. My question is once I correct the field order, I probably can use DGindex again or and AVS script to IVTC the video to get 23.97fps, correct?

The two reasons I want to IVTC is I am using a RAID array to serve video through out the house, and will use a Tivx media player and/or HTPC to watch the video. Also my TV and Tivx can support 24fps, so it's best to do away with 29.97 video.

An I correct? Thanks, again.

if your source is telecined film you can perfectly use IVTC, of course.
But beware of the wrongly signalled field order when scripting the IVTC ;)
