The Making of Slipstream (Released)
Time

Taking a day’s break from my trilogy transfer, I’m doing a DVD of The Making of Slipstream because this is one documentary that hasn’t been released on DVD at all (they really should’ve put it on the widescreen DTS R2 release), which has some big ties to Star Wars, starring Mark Hamill & produced by Gary Kurtz who also produced Star Wars.

25 mins long, it was made at the time of filming so all the interviews are from 1989, the back of the VHS box even says “For free distribution only. Not for sale or hire.” and where did I get it? eBay…

I’m doing PAL & NTSC versions (it was filmed in PAL) and it’ll be completed tonight, unfortunately I won’t be able to post anything out just yet, I’m ill should be better later in the week though, hopefully.

Yep I had a good read of the linked thread and the original thread linked in that linked thread (if you get my drift), I did find it though but haven't had a chance to truly test it out against just normal averaging between 3 captures as I'm working encoding the extras for ESB DVD today.

It was in the test zip you posted: http://www3.telus.net/11811/doom9/TooT_Test_ Kit.zip (thanks!)


edit: I wonder if someone could come up with a version of TooT that does an "Average Best Of X clips", basically TooT that can handle more than 3 sources.

Straying off-topic slightly, do you or anyone else have the toot.rar file available? the link in that doom9 thread doesn't work and I'd like to have a play with that averager.

Temporal smoothing without nasty side effects
Time
I've discovered a way of filtering video with a temporal smoother so the image is cleaner but with less motion blurring side effects than normal.
Basically you temporal filter the video once forwards, and once backwards, then merge the two avis together.

To do this I use two AviSynth scripts and VirtualDub:


script1.avs

AviSource("capture.avi")
Reverse()


script2.avs

AviSource("processed1.avi")
V2=AviSource("processed2.avi")
V2=Reverse(v2)
Merge(v2)



The steps you take are; open "capture.avi" in VirtualDub, apply only a temporal filter (in this case Dynamic Noise Reduction on the default (16) setting) and save the avi as huffyuv compressed "processed1.avi", then open "script1.avs" in that VirtualDub and save the avi as "processed2.avi".
Run a 2nd VirtualDub and open script2.avs, from there you have a cleaner source to work with which has been temporal smoothened but much reduced nasty side effects (notably less motion blur). Ideally you want "processed1.avi" and "processed2.avi" to be on different harddrives to avoid your harddrive being over-worked.


Tested it on a piece of captured VHS and the result is a lot better than just using one temporal smoother on forwards video. Only drawback is the sheer amount of harddrive space you need to do this with and the extra time it takes to process the source capture twice, I tried doing frame serving with two VirtualDubs so the forwards+reverse temporal smoothed videos are fed directly into an AviSynth script to avoid the intermediate avis but it didn't work, it applied temporal smoothing on forwards video only.

External video capture devices (non-DV, non-mpeg) ?
Time
Are the Dazzle products 'ok' nowadays? I ask this because a few years ago when I bought my Canopus ADVC-100 I was researching capture devices and had initially set my sights on a Dazzle DV Bridge but reading many user reviews on the product put me right off buying it (lots of complaints & frustrations), then someone mentioned the ADVC range and just about all the user reviews I saw praised it so I bought one and it's suited me very well.

Ever since I encountered the chroma compression problem with DV, especially red, I've been wondering about high quality uncompressed capture but until now never really had the harddrive space needed to deal with the filesizes involved, nor the need for it. Capturing VHS to DV is fine and wouldn't really benefit from uncompressed capturing, but laserdisc will.

External video capture devices (non-DV, non-mpeg) ?
Time
Logically, uncompressed NTSC (no audio) is about 29.7mb per second of video (720x480x3x29.97), USB 2.0 is capable of 57mb/s speeds, there's no mention of any hardware encoding on that TerraTec Grabster page or on the Articles page where the hardware encoders are pointed out, so there's a possibility it does send uncompressed video to the PC and the mpeg is software encoded on-the-fly with a fast compressor.

The technical specs say the faster the PC the higher the resolution of encoding: Technical Data - Grabster AV 250
(looks like XP only, damn, my video PC is W2k)

This unit might be work looking further into.

External video capture devices (non-DV, non-mpeg) ?
Time
What (or are there any) external video capture devices that can capture uncompressed full resolution PAL/NTSC video?

I know there's a heap of PCI capture devices & graphics cards that can capture to uncompressed full res video, but my experience with them has been that they're always hassle due to the drivers being a complete pain, plus the fact the video signal has to go straight to the computer so there's more chance of RF inteference.

I like my Canopus ADVC-100 because it's external plus I get great capture from it but it's DV so it's already compressed by the time I get to use it and I'm just curious to see what else is out there.

There's two ways of fixing the ESB XviD, re-releasing the full 3.9gb file or releasing a 229mb mp3-wav that can be dropped into the ESB avi using VirtualDub. The glitch is so small you'd only notice it if you were concentrating intently on the film or you knew it was there in the first place (damn I shoulda kept my mouth shut ).
I could put the fixed ESB mp3-wav on the ROTJ XviD DVD-R when ROTJ is done, there'll be enough space because the avi will be under 4gb.

When I synced the Definitive Collection audio to the PAL THX video I had to repeat & delete a frame here or two, repeating a single frame of audio is fine when it's quiet and at the beginning/end of a scene but one spot I had to repeat it 4x and it showed up - it happens when they're blowing up meteors looking for the Millennium Falcon at 52min 25sec.

Nothing major but it's enough to make me go back and fix that tiny glitch in the source wavs then re-encode the audio for the DVDs.

Info Wanted: 'TekWar' & 'Alien Nation' movies - has anyone preserved them?
Time
I'll do a straight dump of the NTSC TekWar LD to NTSC DVD if you want but I have no plans of making an NTSC set of TekWar.


As for Alien Nation, the series was released on DVD from Columbia House (mail order only) and fetches stupidly high prices on eBay:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=6449470696

Good to see it's going to get a decent release now, I wonder how the picture quality will compare...

Some of the Alien Nation tv movies were released on VHS in Australia, "Dark Horizon", "Body and Soul" & "Millennium" at least.

Idea & Info: an OT preservation project in Anamorphic W/S + on Dual-Layer DVD = ?
Time
Ok the way I see it is this, I do notice a picture quality difference between the SL and DL encodes of my fake-anamorphic transfer, the higher bitrate of DL means the detail (grain in this case) can be 'described' (compressed) with more bytes and the graininess doesn't look as bad as on a SL transfer.

You can get round needing a high bitrate encode by smoothing out the grain so there's less detail to compress but this can also mean a slightly blurred picture (looks a bit out of focus) such as with the Dr Gonzo transfer. Throw in some temporal smoothing and it means even less detail to compress but the side effect of this is motion blurring.

Basically the cleaner the source the smaller you can compress the video and it still looks good, a noisy/grainy picture needs a higher bitrate.
