Song Of The South - many projects, much info & discussion thread (Released)

Ok, using an unsupported release candidate of restore24 I've produced a fairly acceptable looking clip.
The bitrate is less then half what the final version is likely to be, because my upload speed is a bit slow.
I also used some denoising/deblocking/deringing.
Let me know what you think.
It's 3 minutes of some random 10 second clips from the first .vob file.

Discuss.

Re-heh-heallly.

So then Restore24 is our guy. IMDB and Japanese laserdiscs releases (on LDDB.com) all say 94 minutes is the original runtime.

That means there is no speed up here, just them whanking around badly with the frames.
I'll have a test clip of Restore24 at work (which I've now added dgdecode's postprocessing for deblocking and deringing).

1 frame per second encoding with that filter... yikes.

Bingo Moth3r, thanks for the lead. That's exactly what was going on.
I don't know if the filter will produce better results than what I've done manually, but it sounds like better minds than mine have been at work on the issue.

Edit:
This is restore24's method... does this sound wrong to anyone else?

1. Bob the video to 50fps
2. Detect fields that are blends
3. Replace those blended fields with unblended neighbors
4. Decimate the cleaned stream to 24fps

In my mind that means he separates the fields... I was doing that.
Detects the blended fields... seems to be the odd field only. Was doing that too.
Replace with unblended neighbors... why exactly?
Decimate... This only makes sense if there wasn't a speed up... which I can't confirm or deny but it sounds like a percentage of clean unique frames might get discarded.

Can someone give me the final runtime of the BBC version (I only have the first VOB)? That should indicate if there was speed up or not.

Duh, I need to correct my idiocy (I'm surprise no one called me on this).

I commented about uberinterlacing (interlacing interlaced footage) but I neglected at the time to mention (or remember for that matter) that I have to do a deinterlace BEFORE resizing down to 480 lines.

The only reasonable method in this case would be motion adaptive (since blending would make everything look like it has trails (worse than before)), but even still... it's ugly jerky movement with artifacts, and that's before the pulldown.

When I finish what else I'm working on I'll grab the rest of this dvd and get to work.
But the even-fields-only look to be the way to go. It's sort of a manual Bob deinterlacing and it doesn't look too bad.
I'll see about posting a clip later.

Sorry for the delay in getting back on this but I've been damn sick lately.

Anyway... just for giggles I snapped some side by side comparisons.
The first frames are from an old boot DVD version of SotS.
I found it as a torrent on Demonoid, but I believe it was from a website called SongoftheSouth.com or something (don't worry the site is long dead).
It's better than a lot of the versions I've seen and does not have really bad blooming/blurring colors or any hard subbed foreign language. It is 29.97fps interlaced. I tried to grab the cleanest frames.

The second frame is the new BBC broadcast with the odd field discarded and then the half-sized image resized to 480 lines.
You'd think the BBC version would lose out since you are using 288 lines to make 480... you'd be wrong.
Both seem to have a lot of compression artifacts so that can't be weighed in the comparison.

I'll try the uber interlaced idea (as described above), but I think this method will actually turn out a passable progressive version.
The PAL release might look better, but it really contains no more video information than what I've done (since every other field is a blurry composite).

Just saw Redeemed and was impressed by how well it worked as an edit.

Besides the out of synch audio at the beginning, I have another technical comment (something I noticed in Superman II as well). When you go from the credits to the movie at the beginning, the letterbox bars and picture go gray. It's fairly noticeable on my TV (and is yet another bug in Womble).
If I recall correctly from when I had the same issue, it's because the cropping bars are removed during fade-ins/outs so they end up not appearing black enough on some displays. It gives the impression that the main picture area fades out and the bars are fading up.

Besides that... very impressed by both the technical and plotting.

Btw, did anyone else notice Harry Potter's Uncle Vernon was one of the terrorists on the Eiffel Tower (the one controlling the nuke)?

For those curious about the oddity that is making this film NTSC resistant:

Typically PAL broadcasts from a film source use 2:2 pulldown. That is, all frames are duplicated (to make 48 fields), interlaced (into 24 interlaced frames) and sped up to 25 frames a second. As a result this pretty much translates to 25 unique frames a second. If you ever notice interlace artifacts it's usually because someone edited it badly and the fields are out of sync. That can still be corrected because there are no duplicate frames as in NTSC and they can be shift back where they belong.

Now for whatever reason THIS movie consists of a pattern where:

http://img201.imageshack.us/img201/3562/sotsyd0.png

So every other field is a blurry merge of 2 film frames and every final frame is an interlaced combination of one good field and one merged field. This pattern shifts during the movie.

This is could be the result of a bad telecine process(?)

I could suss out where the patterns shifts and throw out the blurry fields, but that would result in a half resolution movie being resized to full screen.
Since there are already compression artifacts, our old laserdiscs caps would probably look better by the end of that.

Option 2 is to slow this down and keep all the crap as it is and make a 23.976 fps 100% interlaced video and apply 23.976 to 29.97 pulldown flags.
That could get ugly on playback since your player would be interlacing interlaced frames.

Option 3 involves duplicating frames to make 29.97 frames. And this would result in jerky video.

I'm not sure there is a good answer to this.

No you misunderstand me. It was an idle thought. I really doubt I would go back and do any work on ANY of my finish projects at this point.

I SHOULD have gone for something like aftereffects but I really didn't know about it, and didn't think what I wanted would be possible.
All in all, I am happy enough not to go back to them though. There's too much else I'd like to take a swing at.
Btw, Matrix 2 is much less altered than 3 (if that's what you were referring to). As a result there are fewer surprises but it's much smoother to watch.

Truthfully I only intended to edit Matrix 3, but realized I had to make the 2nd film fall in line with my vision of the 3rd. So I edited the 2nd one first just to cut my teeth.

Anyway I'm taking you off topic. I was trying to say that I've been really impressed with a lot of what people are doing with AfterEffects. I'm going to have to give it a look just to keep up.

Edit: I am correct that you used Adobe After Effects, right?

No I just posted conceptual changes of my edit for the most part. And I agree, when it gets that extensive it's about impossible to keep track. (I've made edits on the fly I didn't even remember doing.)
I'm just afraid I'm going to miss all the nuances of your edit.

After seeing the cool use of AfterEffects I'm wishing I cleaned up a few shots of my Matrix edit with it. I hamfisted cropped a few scenes. Some to remove characters, and once so you couldn't see Neo's head (though I would have preferred a CG bandage on his eyes in that scene).

I don't THINK I'd go back and redo those shots, but you made it look so nice.

Message from drgonzo369:
Since my sister-in-law's frakkin dog ate my power supply cable on my laptop last night, the SotS upload is postponed for a few more days. rar1-rar19 are up, but all my log-in info is on my laptop and I don't want to drain the battery down any more then I have to until I order a new ac adapter. I'm hoping to get it ordered this weekend once I get paid (and money is clear in the bank), so as soon as it comes in (which will probably be next week) the upload will resume and the links will be put up.

Sorry for the inconvenience, but I have to buy the cable and I'm strapped for cash today (which I was hoping to get my paycheck today).

Once it's up, everyone will know.
