HuVideo

[dshadoff]

I finally got a chance to look into some really cool information that tomaitheous had put together previously on the subject of HuVideo.
http://pastebin.com/raw.php?i=EejMA7jF

I was thinking that since the data is uncompressed, it'd be possible to hardsub the cinemas.
I got as far as identifying all of the HuVideos; the next steps were going to be:
- extract the ADPCM for each video for somebody to translate into English
- identify whether any palette sets are relatively consistent across entire videos, in order to imprint the hardsubs into the frame, using existing palette entries

So I thought I'd share the initial information below, since I found it.
Note that Gulliver Boy has over 30 minutes of HuVideo in it (!)

Very happy to see you posting. Looking forward to what you come up with! While early FMV is an easy whipping boy, I think there's a lot of potential here. Let's face it, this is were quick time events came from.

That would be really cool to see some subs for that game. At the very least maybe someone out there will finally translate it.

Hey Dave.

The thing about Gulliver Boy, and Anearth Fantasy Stories as well for that matter, is that the Saturn versions are probably far easier to hack. I could be wrong, but I suspect they had way more memory than they needed when they ported them, which means the scripts are probably stored in more straightforward ways and there's more room to shoehorn in the English.

I read that Gulliver Boy in particular is a very straight port, and the FMV is higher quality and would probably re-encode with hardsubs more cleanly.

It'd be worth a comparison, anyway. Of course, it all comes down to what the people doing that hacking want to do.

[Keranu]

Holy shit, a half hour of FMV! Anyone know how much the Sherlock Holmes games have by comparison? Or It Came From the Desert! for that matter?

Keranu, you, of all people, should know that It Came From the Desert is not FMV but FMC (Full Motion Cinemascope). It supports two widescreen televisions side-by-side.

Are those Bonk hearts!?!?

Damn, you're good! Yes, indeed, they are.

This is a promising development . Good to see you posting!

How hard could it really be to port Dragon's Lair or something to the Duo with Huvideo?
Or perhaps it doesn't really support rapid access between different clips?

[NecroPhile]

Yuna 2 has HuVideo too?  I gotta add that to the ol' wish list. 

[OldRover]

I'm going to go out on a limb and assert that as long as the huvideo clips are on the same track of the CD, I doubt that there will be much of a problem.

Makes you wonder if you really need a arcade card in order to attempt this..

[OldRover]

You don't need an arcade card to stream from the CD, which is what huvideo does. You could preload into the ACD RAM to stream from there, but that seems rather pointless imo.

[CrackTiger]

Has anyone been able to make HuVideo with more than one palette?

[OldRover]

Am I right in assuming that the tile map is really just a list of palette indexes? That is, each nybble in the tile map is really just an indicator of the palette the tile uses? Since the palette index in the BAT requires 4 bits, this seems logical, especially when you consider that you don't really *need* to map out *tile* indexes since they would be contiguous, but the palette that each tile uses could change from frame to frame.

something like that.

Theres a doc that shows you that a portion of the cell contains palette info.   I think it comes with HuC, IIRC.


The palette that a tile uses could probably change every frame, but it would be a pain in the ass to do, and may not perform as good as desired.

Correct. There is no compression via tilemap on the VDC side (most streaming video wouldn't benefit from it, plus it's kind of useless, unless you do a variable frame rate and buffer/cache system). So storing the tile indexes is redundant. Just the palette index is stored in raster map order (horizontal). Every frame contains a new palette for the BG.

 The huvideo player uses custom CD routines to access the drive. It bypasses the system card. The system card functions aren't really optimal for doing such streaming. Plus, the normal system card cd_read function is slower than it needs to be. About 90k per second IIRC. Huvideo requires 122k a second transfer. Some the late gen SuperCD games also use custom CD read functions as well for faster access. I ripped the one from Seiya Monogatari game and it worked great for all my tests using it (disassembled thanks to MooZ's proggy). There's other stuff in the lib too, like LZSS decompressors (with all kinds of source/destination setups. Even LZSS decompress from ADPCM ram to VRAM, etc). Cool stuffs.
