substance wrote: how many jigs do you think 1 hour NTSC video would take in Uncompressed 4:4:4 in quicktime (using Mac)? Way too much (for NTSC HD 1080i). You're not going to gain anything going this route. 4:2:2 is more than enough, and what i used when I did my captures (I did approximately 10 or so MUSE LDs). And hard drive space is the least of your problems. You need high sustained writing ability. I was (thankfully) on an older Mac Pro tower able to capture about 45 minutes are so before the hard drives would begin to chug. But I ran 3 hard drives in a RAID0 config to obtain a decent write speed. Keep in mind, you need a SUSTAINED write speed, not peak. Additionally, what I also found out was over/underscan on the capture presented some issues. Either way, for the movies, I (personally) wouldn't waste your time. To me, there's nothing that needs to be preserved here outside of pure curiosity for those that wondered about MUSE LD. The discs worth preserving are the numerous scenery discs to which hardly any were re-released in digital HD format (only aware of a few Sony titles that were). If you want to have some "fun" - try and capture the decoded B-channel digitally or capture the decoded A-channel track, convert to a 5 channel digital track. I never got around to doing that for Tahiti. Off top of my head, I have converted I think half a dozen NEC Fish club discs; Atlantis (which wasn't on Blue-Ray until recently); and scenery discs like Tahiti, Ferrari of the Art, Ordinary Europe, and I think a handful of other titles. They're all sitting on my server, and I watch them from time to time on a media player or PC.

I can capture 1080i60 uncompressed but once I transcode it to mpeg, it is converted to 1080p30(29.97 really). I think I should capture 1080i59.96 then it should transcode into mpeg without further conversion. The file I have posted is %90 imitation of how Muse encoded films look, we have motion issues (judder) due to 1080i60 to 1080p29.97 conversion. Also the audio is too hot. My intensity shuttle doesn't have any digital inputs, so I used the analog input (not ideal).

substance wrote: Dropbox link to Jurassic Park HiVision LD capture fileIt's a 2.4Gb file for the first 23minutes of Jurassic Park Hi-Vision LD. I transcoded it into mp4 with 2ch AC-3 audio. No alterations, no cropping, no scaling. 1080i60.00 video. You will notice black bars on all 4 sides because Hi-Vision LD is 1880x1030i. Both my Macbook pro(Quicktime player) and windows machines(windows media player) combs while deinterlacing, other than that it looks pretty similar to what I see on my TV when run directly from the disc through the Lumagen Radiance 2144. Let me know if the link doesn't work. Fantastic video! I know it's obvious but it's basically like HD but in analogue form - it's not artificially perfect like Blu Ray. The quality is excellent and picture is sharp. I urge anyone who's remotely interested to check it out as substance has done a great job!

Very excited to see you taking a crack at this! Thank you very much for the sample video. Lovely to watch. You should be able to encode 1080i60 to interlaced H.264 without issue. I see you used Handbrake, which I've only personally used a handful of times. It's oriented toward progressive encoding, but that's a limitation of this specific software, not MPEG-2/4 in general. In the "Additional Options" box of the Video tab showing "H.264 (x264)", try adding --tff. Keep the frame rate at 30. 1080i60.00 is not a concern for file-based playback, and if you want Blu-ray compatibility you can just remove the pulldown before encoding the captured file, as mentioned before. I believe Handbrake is capable of this, though it would be an auto mode that can fail on certain scenes. I would personally prefer to do it manually, but that may require Windows. I did a manual IVTC on this sample clip, and the pattern is 100% consistent from start of the Universal logo to end of the sample. So it probably only breaks on side changes. I'm not an expert with regard to H.264 encoding settings; I pretty much pick an x264 preset and go with it. But I do have extensive experience with capture and processing (exception: color correction). Perhaps you'd be open to discussing via email so that we can both respond faster.

First of all, thanks to substance for the clip! I found it recently, and I like it very much! Not BD quality, of course, but better than a DVD, and I think just a little bit short of a 720p HDTV broadcast (apart interlaced vs progressive, of course!). More, it has a different color grading from any other known released versions and HDTV recordings... it will be great if you can provide also the other sides, so a restoration using the MUSE color grading as reference could be possible. Thanks again!

Hey, you have an impressive video chain Substance, but what about the audio side?
I know i'm new to the forums, but I've been trying to take a stab at these captures for a while, just regular LD's though... and a pre-amp before the audio signal hits the capture device is almost necessary for older analog or stereo in general rips. I personally use the Sennheiser HDVD800 to handle my DAC/amp needs for the stereo LD's (and listening in general, the HD800's really are magic!)

My audio is gear built around McIntosh Pre-Pro and Power amps. All speakers are Martin Logan electrostatics, currently at 7.2 but the plan is 7.4.4 in the near future. As for my capture gear, video is the primary concern. Lumagen Radiance 2144 is going to transcode the analog/digital audio into the HDMI stream which will be fed into the capture card.
