HD to DVD issue

[robjv1]

I am pretty new to this type of converting, so here goes .

Okay here is what I have:

I have a high-definition concert recorded as a .TS stream on my hard drive (file is 1920x1080i) that I have converted to DVD using Procoder 2. I took the original stream and used MPEG DVD Video Wizard to edit out commercials, ProCoder to resize and encode the video (just kept the original audio stream and did not re-encode it - 6 channel AC3 audio at 384kbit/s and re-encoded the video at 6384kbit/s VBR, 2-pass mode) and then used DVD Lab Pro to burn it to disc. Everything seemed to be moving along just fine (I checked out each video I created in VLC player as I went along) until I burned it to DVD. When playing the DVD on my standalone players on my TV sets it perfectly for the first two songs, but the next few songs the video gets jittery. It seems to depend on the deinterlacing mode on the DVD player. On my JVC DR-M100, it played fine for the first two songs and then with subsequent songs I could eliminate the jitter by switching it to the "FILM" deinterlacing mode (as opposed to the AUTO or VIDEO modes). I tried switching it back to AUTO later in the disc and found it worked fine on some of the later songs, but on others the mode still needed to be set on 'FILM'. On my Oppo 980H (my main player), the video plays fine on the first two songs, but I can't adjust the deinterlacing on this player, and it just plays jittery on all BUT the songs that play fine with the AUTO setting on my JVC.

Then I went back to play all of the original files on my computer to determine where I might have gone wrong, and I found that all of them play fine with VLC regardless of whether I had deinterlacing on or off, but when I tried them in PowerDVD, I could recreate the same jitter or a similar looking problem. My question is, what can I do during the Procoder step that would prevent this from being an issue on my players? Procoder identifies the original file as interlaced lower/bottom field first, so I matched the setting in my target video settings, but could Procoder not be identifying the field order correctly and/or can it change during the course of a video? Is it related to the fact that maybe the concert mixes film and video content? Would using the "Film Decode" option in Procoder solve the problem, or should I start somewhere else? Am I pushing my luck with the bitrate? The disc is almost completely full.

Just to restate, the jitter is clear from the original file down through the DVD files when played with PowerDVD.

Any help would be appreciated! Thanks again.

The easy way with minimum fuss :- near the bottom of https://forum.videohelp.com/topic338564.html#1764785
Just adjust from PAL to NTSC settings (576 -> 480 and pal-dvd -> ntsc-dvd) ...

Resizing interlaced video is very tricky and leads to the results you are seeing. I don't resize for that reason. Others here have provided some expert advice in the past on ways to resize using Avisynth scripts that can eliminate or greatly reduce the problem, so perhaps some of them will provide some hints. My understanding is that basically interlaced video doesn't have enough information for the resizing to work correctly all the time, so the resizing algorithms make wrong decisions on various frames from time to time which leads to the jerkiness you see.

Oh, a discussion on resizing interlaced using avisynth ? Lots of them. Here's one starter ... http://forum.doom9.org/showthread.php?t=129933

ffmpeg does OK at it too per the above "minimum fuss".

No ffmpeg doesn't after all. The ffmpeg user mailing list confirms what I subsequently found out by testing and examining the bitrate in a btrate viewer... ffmpeg produces s bitrate spikes in the resulting output file which go outside the DVD spec.
