Maybe eac3to is that smart?
Sure, why not?
Surely I'm not the first to think of that idea.
Shirley might be an eac3to developer :)



Back to frame counts, I think I'm noticing a trend.
Seems like each movie is split into three 'chunks' for lack of a better term.

___ANH_________ESB______ROTJ__0-thru
_85225_______75306_______84511 -thru
147672______151133______142918 -thru end

Sometimes the chunk size match the LD sides, but not always.
Among NTSC LDs the pulldown cadence doesn't change at reel boundaries-- it only change at chunk boundaries (or side boundaries) which make them easy to IVTC.
The chunks are all less than one hour.
I'm wondering if those telecine were stored on three tapes recorded in "1-hour mode" if there exist such a thing among professional tape formats.

Metal has already pointed out some spots where digital broadcast was breaking up and frames went missing.
Besides those type of transmission errors, do we know of any missing frames
which are NOT surrounding those chunk boundaries?

I also wonder what would be the easiest way to convert this from 44100hz to 48000hz?

CapableMetal said:

The conversion from 24 to 23.976 is so easy to do and is more compatible for those with older hardware

Both of those tasks can be done in one step, and it's the preferred solution IMHO.
I talked about that before in over in the sound thread (there's a link in the first post of this thread) and I'll repeat some of it here.

Sample Rate Conversion (SRC) should only be done once, if possible.

It's a bit like colorspace conversions in the video realm, with similar reasons for trying to avoid it.
For example if you had a video filter which only works in RGB space, then you have no choice but convertToRGB() in your script.
And you can convertToYUYV2-something at the end of the script to suit your encoder.
There are valid reasons to do colorspace conversion, but do not want to go back and forth too many times if you can avoid it.
It's a bit 'lossy' in a sense, even when using a lossless codec.

In the audio realm the same guiding priciples apply.
SRC is 'lossy' in a sense, even though WAV files aren't.
Best doing it once than twice in your workflow.

If target is true 24fps then it's only one step.
Use your favorite software (iZotope RX Advanced if you can afford it)
and convert the DTS files from 44100 to 48000Hz.

Now if the target will be 23.976 it could be a two-step process.
First 44100 to 48000, then 24 to 23.976
But that's resampling twice, and we'd like to avoid that if possible.
We can avoid it! Here's how.
Use iZotope or whatever to convert from 44100 to 48048Hz. Not a typo, I did say 48048.
Then using (SoundForge, Audacity, Audition, Vegas?) to edit the WAV's properties and force the rate to 48000, without resampling.

It's a bit like using AssumeFPS() in the video realm-- it doesn't change the total frame count.
When you force 48048 to 48000 in the WAV's header you're not changing the total number of samples, but rather slowing them down to NTSC speed.
Slowing down without costing the extra step. Does it make sense?

the first frame of the last shot
Do you mean the last shot before wipe to credits?
(My 2004 DVD is sealed in polythene, so I can't even count that one.)
Using msycamore's proposed numbers (which I'm not endorsing yet) it came out to 183,826 in my script.
183.825 is the last frame of Mr.Shaw's ghost.

Are we in sync?

the Reivax broadcast is missing 15 sequential frames during the Ben/Vader duel alone!
Not 15, it's 50! (132114-132163)

I wonder if the laserdiscs have the same frames missing.
Over the past weeks I've been comparing US & Japan LD captures.
Not my own caps-- I don't own those LDs, but ones available on usenet.
Both sources are raw 29.97fps pulled-down which is good from a certain frame-counter's point of view.
Lots of IVTC'ing ensues and by this point we got sync scripts for US trilogy & Japanese sequels.
US & Japan have different side breaks in some cases, which is also good for frame-counters like us.

Looking back at some notes from Sept, the US ANH LD lacks
85225-85226
147671+147672
and it's missing one field of 162630.

Should be able to provide more specifics for sequels in the coming days.
Earlier in the thread I agreed with msycamore about inserting 75305 into ESB.
After noticing variation between US & Japan versions I've had some radical new idea about that.
If we're to believe the audio evidence, perhaps two frames are missing instead of one.
I need to present that evidence here.

ROTJ frame counting is finished but I haven't done any audio analysis of that one yet, so I can't comment on msycamore's proposed numbers.

Harmy's STAR WARS Despecialized Edition HD - V2.7 - MKV (Released)

analog said:


Ok, questions - first, I got an edition that is "Fixed_DeEdv2.0" - do I still need to mess with audio?
Yes.
The uploader (not me) simply renamed the files, adding the word "Fixed" in front,
in order to fool his news-posting software which had aborted on the first upload attempt.
To make the software start fresh, he renamed everything.
They're exactly the same RAR files he got from tehP, just renamed.
At that time the audio error hadn't been reported yet.

analog said:


Currently found what I did on n e w s groups, which, THANK YOU to whoever put what they did on there! Just can't seem to find that darn AVCHD version (for SW 2.0 anyway).
At my favorite binsearch engine I typed "AVCHD" in a.b.starwars and it popped up #1 search result.
Says it require password. Is it same as tehP? I'm not sure.

The sons of Japheth; Gomer, and Magog, and Madai, and Javan, and Tubal, and Meshech, and Tiras.

And the sons of Gomer; Ashkenaz, and Riphath, and Togarmah.

You left out Shem's other brothers Larry & Mo

I've no doubt they'll sign too

Anyway thanks to an acquantiance I've been able to aquire a better quality version of the cartoon from the 1080p blu ray rip with better stabilized borders and sound.
better stabilized? no borders?
G wish i knew where to find one of those.
You have nice acquantiances!

STENDEC's Hybrid SE (part-finished project?)
Time

STENDEC said:


Just a quick update on my progress, ANH is now finished and I've started on ESB. As with ANH there are quite a few missing frames from the TB release, but the GKar is mostly intact. There is one important issue though. It seems that all releases of the 1997 SE have 1 missing frame. It occurs at frame number 75282 on the 2004 DVD (and the Blu-ray as well, presumably). It's the last frame of the asteroid hitting the bridge of the Star Destroyer and for some reason it's not in any of the 97 releases - TB, GKar or Laserdisc. With that in mind, I'm planning to leave it out since the evidence would suggest it wasn't there in 97.
Disagree.
There's overwhelming evidence to suggest it was there in '97.
That being the DTS soundtrack, which definitely include that frame.
If you omit that frame from your video, then you need to cut ~42ms (period of one frame) from the DTS soundtrack.

Incidentally, we called it 75305 over in the "standards" thread

Print variations in '77 Star Wars

Okay so we'll forget about that wipe to Tatooine.
Instead of three, just consider two instances of shrinkage (70632 & 128032).

I've presumed the shrinkage happened at the telecine stage.
Imagine the telecine operator finishing a reel at 5:00PM then going home.
Next morning he starts the next reel. He hasn't turned any knobs or changed the machine settings from the night before; nevertheless, the machine hasn't reached operating temperature yet, so the framing ends up slightly different.
I've imagined a scenario like that ... but he would've been using 1000ft reels in that case.

Now let's throw that idea out the window.
Let's imagine the shrinkage was introduced earlier, whenever the 1k chunks were printed onto 2k reels.
Then the 2k reel suffered the blob damage later in its life.

Is -1 following this thread? I wonder if he could provide uncropped images of these four frames.
If we could see those frames uncropped with sprocket holes and all, do you think their exposed areas would align?

You can actually see some small amount of shrinking in the SC telecine as well, see the first wipe in the film to Tatooine for example, the bottom border gets a little larger as it progress. Another thing to watch unrelated to this is the last shootout scene right before Vader makes his entrance on the blockade runner, it actually looks like they spliced in a different source for that short sequence.
If I understood you correctly, that's also a 1000-foot reel change (12676)
just like the other shrinks (70632 & 128032) are 1000-ft changeovers.
