I've tried averaging between different players, but the standard algorithms won't work very well. You need to do some tracking and alignment passes first to have any hope of it getting a result that doesn't add more problems than it solves.

The black bars are only 54 for NTSC on your capture? How come the difference, is that because of the PAL source being cropped funny?

Now you've got me wondering if I should have resized my edition differently.

Btw, why would anyone bother to try to convert the Divx to DVD if you're already doing that yourself?

So laserdisc players are like VHS players in that no two models will output the same alignment with the same source? I thought that because the picture storage quality of laserdisc is higher there'd be much more chance of good alignment between players.

It's because of the resizing calculations I'm using, the ITU-R BT.601-4 standards to be precise.
My main reason for making the Aspect Ratio Calculation Tool - ARCT, was for using it on my trilogy transfer from letterbox to anamorphic, the source x,y numbers I set as default on that calculator are those of the PAL source I'm working with.

Btw, why would anyone bother to try to convert the Divx to DVD if you're already doing that yourself?

Because they'll only know I'm doing the DVD version if they're reading these boards, downloaders might not read here.

Yeah pretty much like VHS but a lot more stable, but you still are in the purely analogue domain with the picture, and even slight differences in the ouput components is enough to make it unusable. Even between the same models of players you can get a difference enough to cause a mess.
You can align it all, or adjust your players to get a match if you want to put the time in.

Oh well that idea of two laserdisc players' capture merged idea is out of the window then.


I am right now burning off the first DL DVD of ANH in NTSC

edit: .....which turned into a £2.40 coaster

Been reading up & downloading latest versions of stuff so hopefully 2nd time lucky.

edit 2: another £2.40 fecking coaster if I can't get a successful burn out of these 10 DL discs I'll go single-layer instead, putting the extras from the films on a 4th disc

edit 3: third time 90% lucky, flashed the burner to the most recent firmware and I can play the DVD, almost, running low on harddrive space so the ISO was fragmented and couldn't read the data off the hd fast enough so near the layer change the disc becomes unreadable, however the picture quality is amazing compared to the single layer DVDShrink version I was testing on a RW disc for the menus etc.
Now on burn number 4, 94% done and another 50 mins till the verify is complete (wish they'd hurry up and make them cheaper/faster)

I'm starting to dislike making dual layer discs immensely... because of the cost and them not being as reliable as pressed dual layer discs.

On the 4th burn I'd rebooted my machine & cleared out space so the ISO wasn't fragmented on the harddrive, burn speed stayed steady but DVDDecryptor failed verify when it started to read back the 2nd layer
My portable DVD player handled the burnt disc fine, no pausing or stuttering when it reaches the 2nd layer because it's got an over-powerful laser and can play almost any disc you throw at it, but my main DVD player pauses for the layer change and then stutters badly during the next 10 mins of footage.

Then my burner started to refuse to read discs at anything other than 1x, didn't dare try burning anything with it in that state, so I got the unit out of my PC, took it apart and manually cleaned the laser head, put it back together and into the system and it read DVDs back at max speed.

Then I burnt disc no.5, it failed on verify at 53% which is a lot better than previous attempts because it meant it read through the layer change ok, so I tried it in my DVD player and it didn't pause or stutter at the layer change! but it still stuttered slightly a minute or two after but the player is old and the optical out started failing a few months ago (I think I need to clean the laser lens on that too), so I tried the disc on the player downstairs (exactly the same model but a year newer) and zero problems playing it on that one, you couldn't even tell there was a layer change and it didn't stutter for the 2nd half of the film at all.

Now burning disc 6 for DarkGruson but will have to persuade someone else to post it, I'm still ill (stomach aches, headaches, usual feeling like death thing)

If you haven't already checked out this site, it has good tips about what media to use

Thanks I'll check it out. The 10 dual layers I bought are Ridisc because I use their single layer ones and haven't have a problem with them, my problems burning the dual layers has been down to old software and dirt on the lens. I'd use Verbatim if I were rich, but no job means I have to be careful what I spend my money on.

I'm watching the dual layer NTSC disc on my 28" widescreen right now and you can really see where those extra bits went, the picture far outshines the single layer version DVDShrink did of it.

If you can get me a copy of the dl I can upload it to a.b.starwars! You could always split it across 2 SL dvds by rar'ing the image/folders, then you would not have to 'waste' a DL disc on me

No problem, looking forward to your transfer

I've heard that ritek often have bad degradation though, and I don't think that their dual layer compares to other media.

btw that forum rocks the people there are really helpful

segaflip, I was intending to use two single layers to send out the ISO, raring it up into 50mb files (or what size files are usually upped to usenet?) with the .nfo included that I still have to write and say how to burn it with DVD Decrypter because you need the sector number of the layer change, I updated my feedback thread with that sector info in too.

I've not yet had a completely successful dual layer burn, burn 6 is another coaster and won't even play fully on my robust portable so that's about £14 wasted on a few discs... I've just emailed the place I bought them saying 6 out of 6 burns failed verify and did they give me a bad batch, compensation/replacement would be nice becuase if I can't get a successful burn I'm ditching dual layer as I really can't afford to throw this much money at trying to get a single disc to burn properly, and restort to doing single layer versions with no extras which means 4100kbps avg instead of 7100kbps avg for the video.



edit: anyway it's painkillers and sleep time for me, I've had enough of this DVD burning crap for one day

Hmm, it might be cheaper for you to buy a better DVD burner.

For DVD releases, it's usually 50,000,000 bytes.

What software are you burning with, and at what speed?
I haven't had one DL coaster yet, I've been using HP branded discs in a cheapo LG DL burner.

I'm burning them on a Pioneer 108 DVR with DVD Decrypyer at 2.4x, because with DVD Decrypter you can specify what sector to place the layer break at, I put it at the start of a scene where the prison guard says something about not being notified about a prison transfer.

edit: I got a reply from the place I bought the discs from, fat lot of bloody good that did me, all it said was that they're usually reliable discs and I should be using the latest drivers... no shit sherlock! think I'll put dual-layer on hold for now till the media is significantly cheaper and reliable, I can't afford this crap unless someone who can burn dual layers without a hitch can help me out? I can pay for blanks but not half a dozen coasters just for 1 burn that almost works

Well, that isn't really a fair comparison, DVDShrink transcodes rather than re-encodes, which works OK for making a 'barely dual layer' disc into a single layer one (e.g. compression at 85% of original size or so) but any more compression than that and it starts to fall apart.

To get a real compare of the dual vs single layer, you would need to encode to single layer in the first place - the results will be very different to taking a full DL disc and dvdshrinking it. At the least if the DL disc is the only 'master' you have, use something like DVDRebuilder with CCE and re-encode to single layer and you will get a better result on a 'full' DL disc being compressed down to SL and it isn't much harder to use than DVDShrink.

I've started encoding the film at 4100kbps 7 pass and going to make a single layer ANH disc tomorrow when the encoding has finished, then going to test it against the dual layer burn that almost works, if I can't see any real quality improvement by using dual layer instead of single layer I'm going to go single layer because it's significantly cheaper and easier to work with.

I would love to try and get a good burn for you if you send me a image! I use a Pioneer 110D DVR and have never had problem using the same media that you have.

I've not got a dual layer burner, but I have found DVD Decrytper to be a bit flakey for burning discs. Especially if i have any other software running at the same time (and we're not talking intensive stuff), chances are DVD Decrypter will turn that disc into a coaster. Nero on the other hand has proven constantly reliable.

Its a costly experiment, but trying different software sounds like a good idea before ruling out that batch of DL discs entirely. And if you've not tried it, burning at the lowest speed might be a bit more reliable.
Just annoying that it'll cost a fiver to find out...

segaflip, I'll put the dual layer image across a couple of single layer discs and post them to you, I don't know when because I can't get out to the post office (I hate being ill like this, can't do squat ), which also means I can list stuff on eBay & post the items to make some money to pay for new discs.

s7en, I ruled out Nero for this task because as far as I can tell, you can't set where the layer change happens which is very important.

I was going to say the same thing as Laserman. After about 70-85% DVDShrink's on-the-fly compression is not nearly as good as a re-code with something like DVDRebuilder. There's a huge difference in quality at that point.

Instead of going for visual difference between your new SL and DL transfers try something like BitRate View. Get the average and peak q values of the elementary video streams (before authoring) for both the SL and DL encodes. That will give you a better reference as to the real difference between your two versions.

Laserdiscs, even PAL, are soft (up to 5mhz analog, thats like 544x576 digital resolution) and the q values end up quite low. That's why I re-coded Moth3r's to allow for PCM audio, there was minimal difference in quality if I had used a DD track and put the extra space towards the video.

I've now created a no-extras single layer NTSC ANH, audio/menus are exactly the same as the dual layer except video is 7-pass 4100kbps avg instead of 4-pass 7100kbps avg, I'm not seeing any significant picture quality drop of the single layer compared to the dual layer on my 28" widescreen tv, but I'm sending both discs to DarkGruson so he can see the two versions on his big rig.


Now I have the drive space I'm encoding the PAL version of ANH, should be cleaned/encoded/authored by Monday, dunno about burned though

Things are (as usual) taking a bit longer than I thought, just started encoding the PAL mpeg video today, so another couple of days, once finished I'll send the PAL & NTSC dual layer versions to segaflip, rar'd onto single layer discs for reliability.


I've been watching the NTSC version too much the past couple of weeks and now I'm watching the quick PAL version I did a while ago with the audio pitch increase it's like everyone's on helium, argh I got used to the original pitch! but I really couldn't get used to the 3:2 pulldown, now that is horrible, nothing like watching a space fight where none of the ships are moving with any smoothness...

DarkGruson should be receiving his copy of my dual layer NTSC ANH any time now so hopefully some feedback from him
I've posted segaflip a copy too so if all goes well it'll appear on a.b.starwars in just over a week's time.

Been quite busy this week so SW has taken a small breather, this weekend I'm going to set to and complete dual layer PAL ANH, everything's encoded just need to author. Then once I'm satisfied with the PAL disc I set to on ESB transfer next week, with 14 hours of digitising involved...
