How do we copy Interlaced movies???

[Roveer]

I started this new thread so it wouldn't have all the baggage of my previous post and the title would be correct for the questions being asked and answered.

This weekend I tried to copy two 'interlaced' movies (saving private ryan, and titanic). After doing my usual process (smartripper,dvd2avi(forced film), vfapi, cce, pulldown, dvdmaestro), all I got was a big mess. I then ran the original vob through bitrate viewer and noticed this was an 'interlaced' film I'm guessing I haven't done of these before, because I havent' seen tese kinds of problems. My original method produced a mpg that was very fast and unnatural. Attempts to fool around with 'progressive box in CCE and 'force film' in dvd2avi seemed to fix that, but I still would have frames that were blurry and ghosting.

In a nutshell, how do we process 'interlaced' movies?

If I remember correctly from my DVD2SVCD days, that program would use IVTC (Inverse Telecine), to deal with this type of content? Is that what we should be doing?

It seems that each week I'm encouring something new. Hopefully there won't be many more things, the list is getting pretty long. (interlaced, multi-angle, RCE etc...)

Thanks for all your help.

I think your biggest problem is that you have the incorrect field order settings. With incorrect field order settings, video will tend to "ghost" on fast moving scenes. Load one of the original *.vob files in bitrate viewer and view the field order setting, lower or upper field first. In CCE, match the field order setting with the original setting before you encode. Hopefully this will correct your problem.

Bitrate Viewer says that Field Topfirst: YES, so in CCE I checked Upper field first. Still blurry & ghosting every couple of frames. I tried again with Upper field first unchecked, still blurry (maybe even blurrier).

Here's what I was doing.

Ripped with smartripper
preview in PowerDVD (crisp)
DVD2AVI (small portion) (field operation NONE)
VFAPI (GUI)
CCE Settings:
CBR for test 6,000k
Video (add sequence end code, upper field first, dvd compliant)
Lum: 16 to 25
Intra DC Auto
Aspect ratio Dar 16:9
TimeCode 0:0:0:0
GOP
M=3, N/M=4, Seq header=1
Quality
Q=5
No Noise filter

Any suggestions?

this is much the same question as I asked in
http://forum.doom9.org/showthread.php?s=&threadid=19009

Haven't had the time as yet to implement the suggestions from Doom9,
but I believe your two choices are:

run the d2v frm DVD2AVI thru TMPGenc - just doing de-interlacing if you wish to continue on with CCE - Dooom has a guide covering this under VCD/SVCD - the DVD2AVI section contains the link

the other option is to use DVD2AVI, then use Avisynth and a de-interlacing filter by setting up an .avs file, then feed this .avs file to CCE 2.5 or less

At least this is what I take from replies - will try out shortly

If others have input as to the best avs instructions to use, I'm interested.

What is best deinterlacing filter to use, and what is best command line for this?

I got a very strange result last night. Can't figure it out.

While I was playing around with encoding Saving private Ryan I would DVD2AVI a little 2 minute piece, vfapi it into CCE I would take the mpv file and rename it mpg and play it in PowerDVD it would give a few frames then a frame or 2 of blurry & ghosted At 1x it would look OK, but you chould see it wasn't quite right.

I decided to install DVD2SVCD to see how it would handle this movie.

It turned on 'force fim' and did 'progressive' in CCE. I thought that was strange, so I let CCE run a bit from DVD2SVCD and again renamed the mpv to mpg and played it in PowerDVD and it looked just fine (no blurry or ghosted images).

I then went back to my process and tried a few minutes, and it looked just fine too!!!

What changed after I installed DVD2SVCD???

I set up Titanic on my other PC which is where I usually encode and it failed in CCE with a rather non-descript error (encoding failed).

What's up with these movies. I'm most certinly doing something wrong. I'll read the previous post and see what they are advising, but these two are driving me nuts.

Any other suggestions would be appreciated.

follow-up on my attempt to encode Saving Private Ryan. As I mentioned in my previous messgae, after fooling around with DVD2SVCD and making some changes in CCE (possibly adding zigzag scanning order), CCE encoded without any errors or blurry ghosted frames. Funny thing is, I did this as 'force film' in dvd2avi and 'progressive' in CCE. It encoded without errors.

The DVD2AVI demuxed AC3 audio stream would NOT import into DVDMaestro. It gave a 'lost sync' error at 57%. 1 run through AC3FIX cleared that up as if found one frame out of whack. I'm betting it gives an audio blip at that part of the movie. I put it all together in DVDMaestro and the resulting VIDEO_TS folder is playable in PowerDVD with acceptable video quality and audio that's in sync. I also went out towards the end of the movie to make sure I didn't have sync problems as a result of having to 'fix' the audio stream. It seems to have worked fine.

This was a long movie (>160 minutes), so I had to encode at like 2,800bits The picture quality isn't stunning, but I don't feel like breaking this up onto 2 DVD-R's.

Next up is titanic. This is a Gigunda movie (like 190 minutes). I may actually put this one on a double sided DVD. I was having trouble encoding this beast.
