Ah! Sorry, somehow I thought you had said you'd need a MPEG2 or VC1 codec.

I'm very new to this, but couldn't HappyFunBoater simply download the exe, extract the iso, burn it to DVD and run that on the HTPC? I've got an HP laptop that I use for BD and that's what I did. But, I'm likely over-simplifying all this Codec, MPEG, colorspace, gamma curve holy-crap-ness.

We already have MPEG2 and AVC versions of the patterns... but not VC1. We could make either MPEG2 or AVC available in file format, which should work for most people.

Your HP already has software that will read and decode BD... the problem is that his HTPC does not and he is too cheap to buy it

I think that would be fine. And once it's in the MPEG2 format it's easy for us to use tools like Windows Media Encoder to make an WMV-HD file.

One complication with computers is that different decoders can function differently, so for example an mpeg2 decoder might not necessarily work the same as a VC1 decoder. This also means that different programs won't necessarily work the same either (use the same RGB levels). If you're using popular commercial software they should have accounted for this and everything should match within that program, but for programs that use multiple third-party decoders it's basically like running different programs and things might not match. Anyway...

Vista can read UDF 2.5, and by default XP cannot. There are ways to allow XP to read UDF 2.5, but I've never had a reason to try the items Google returns. If you can read the AVCHD/BDMV, then you have access to the AVC video in an m2ts container.

Yeah, funny but I couldn't bring myself to install the UDF 2.5 tools either as much as I wanted to try the videos.

Are m2ts and ts equivalent? I know I can play 1080p ts thanks to the nvidia purevideo decoder, I've used the ones from w6rz.

Sorry if I'm beating this to death, but I just found an incredibly simple way to convert the AVS REC709 HD-DVD to MPEG2. I'm sure this is obvious to you folks, but I figured I would post what I learned. I'm curious if there's a flaw in what I did.

First, similar to how VOBs work on DVDs, I simply used COPY /B to append the four EVO (Enhanced VOBs) files on the HD-DVD to make one large EVO.

Second, I used EVOdemux, a free app, to split the EVO file into an MPV file (video) and an MPA file (audio). During the demux I realized that the video encoding in the MPV file was simply MPEG2.

Third, just like with a DVD, I simply renamed the MPV file to MPEG2.

Voila! I seem to be able to load the file in my normal MPEG viewers and everything is fine. Is this all it takes?

That's one long timecode, but I don't see any issue with the general process of joining and demuxing. Blu-ray stores things more in individual sections and less like DVD, and tsMuxer has a demux option similar to the listed program for HD DVD. While most of the patterns we've used by permission are marked, I'll just repeat the item on the first post not to redistribute alterations such as what's discussed here without the credits that are currently included on the title menu.

No worries; I won't distribute this, with or without the credits. Also, I forgot to include the EVO with the title screen, so I'll go ahead and add that back in, just in case.

I haven't really messed with WMV. Is it an entirely different codec, or is it just a container? If it is a container, can WMV hold h.264/AVC video? If a codec outside of MPEG2 or AVC is required, then it will substantially increase the difficulty.

Since I haven't been able to burn your data to a disc (yet) I have no idea on what patterns you already have but I'm wondering about one specifically . For those of us with CIH setups it would be really nice to have a 2.35:1 window inside of the standard 16:9 with circles in each of the four corners .Thus when the vertical stretch is applied and the lens rolled into place we could check and see if the circles are still circles or ovals . Does this make sense ? I imagine some people might like vertical lines inside the circles to check for pin-cushioning at the extreme stretch as well . Just a suggestion .

Thanks and looking forward to the new release .

There had been a couple prior requests for a 2.35:1 pattern. I made my best guess at what was being suggested and just took 1920/2.35 and rounded up to 1920x818. Anyway, attached is what's in the current working video. If you want you can draw something on the image to illustrate what you're talking about. It doesn't have to be pretty, but not being familiar with the setup I have no idea what sort of distortions are common and what exactly would be useful to include in the image.

Well , if I had skills or talent , which I don't , I'd whip up some circles and plug them into the four corners of the 2.35:1 window you made . However since I don't , I'm not going to be of much use . Maybe someone else can grab this ball and run with it ?

I would be careful transcoding or re-encoding. It can be done, but you have to make sure that the encoder isn't messing something up.

OK, I'll just stick with the MPEG2. Given how I extracted it I assume that it is as "pure" as the original HD-DVD disk? I planned to use that MPEG2 to start calibrating my HTPC.

Well, I can't make any promises but it seems like what you did should be fine. As long as you are just switching containers and so forth, it doesn't normally mess anything up.

Seems like a stupid question, but what type of file should be on the disc after burning? My new Pioneer BDP-51 won't load the disc, the front panel display shows data disc and won't play it. Exploring the disc through windows shows AVCHD RC1 as an .iso file. Is this correct?

Thanks,

It sounds like you burned the .iso file to a disc.

The .iso file is a "disc image." you need software that will burn the .iso as an image, and not just as a file to a disc. The .iso is like a container for the disc contents. It nicely and neatly wraps up the disc files and contains extra information that tells burning software how to burn those files to a disc.

What software are you using?

I had someone at work burn it for me, don't really know what they used. What do you recommend, for burning the disc?

Yeah , me too Just think , you guys will have the only disk based software that has this pattern ! Miles ahead of everyone else , professional or otherwise , and they've been at it longer . Go figure

No to get Imageburn and practice on your current disc .
