Hi all,

I'm doing one of the two first HD thesis films at my university this year. We shot in 720p DVCPROHD and I'm doing all my FX losslessly. Everything looks wonderful!
However... though the school has a projector that can handle 720p, they have no quipment to project in HD. I would like to make sure I'm dealing with the best possible projection. I can either use an SD format they support or try to come up with a way to connect to the projector and provide an HD signal. Any advice on my options would be much appreciated.

1. Project off of a miniDV tape. this seems like the worst option to me.
2. Project off of a DVD. I feel like this is probably better quality than miniDV when coming from a 4:2:2 source, but I could be wrong. Any thoughts?
3. Try to find someone on campus with an HD-DVD player or XBOX360 w/HD-DVD drive and author the an HD-DVD on a regular DVD. It's only 12 minutes, so it should fit. I've heard this works, but have never actually tried it.

Anyone have any comments or other suggestions? The school has been trying to get me to downconvert to DV at virtually every stage and I'd hate to give in and project in DV after all my work to do the first HD film here. argh!

Thanks,
-Colin

ps. Here's one of the latest VFX shots: http://colintheys.com/files/hnb/keys_h264_v2.mov It's not perfect, but I've got to move quickly!

Yea, going through all the trouble making it look great in HD and outputting to DV or DVD must be quite dissapointing.
Going to HD-DVD or Blueray is also gonna be quite a problem.

But how about hooking a laptop up to the projector and play it on there (quicktime video with good compression and full size)? I think that's the easiest way and gives good quality :)

...which leads to the most important question: what kind of inputs does that beamer have?

i think that if the beamer has a DVI in (and your laptop has a DVI out) you have the best chanse to have a good quality projection.

if you go for SD projecting i would go for miniDV over DVD as a better option because the compression of a dvd is higher then that of a miniDV (and it's both 4:1:1 btw).

you can try to find somebody with a HD-DVD player in the form of an xbox or whatever ... but will you find somebody with a HD-DVD writer, personaly i havnt seen many (affordable) of those in the "consumer market" as of yet :)

Depending on the I/O options of both your camera and your projector, you might try (if you still have access to it) just hooking up your camera to the projector direcly and play it on there

I would hook up a laptop (or handy portable PC/mac) if its possible (no messing about with transfers - tho possibly a bit of an effort in terms of hooking it up) - can project direct from source and will look best quality possible.

If you can get an HD-DVD set up thats great, but possibly a bit expensive (and how would you burn the disc?).

Mini DV is better compression then DVD, but when you watch back a high quality DVD and a Mini DV source it is hard to notice any difference really, however, you dont want to downsize and so neither option is ideal. DVD is just easier as you only have to carry round a disc.

I am surprised the course wants you to shoot in HD if there is no output options, but at least it will look as crisp as possible. Laptop/PC/Mac projection seems to be the ideal.

Thanks for all the great input!

First of all, the projector has a DVI and VGA in directly. They would prefer I use the rack, which has only RGBHV, but I figure I can probably talk them out of that. I was told absolutely no computers for projection, which is frustrating. But the reason is that a professor tried to project some films off of his crappy laptop once and it froze in the middle. So they're scared of that now. sigh. Otherwise, that would seem to be a good solution if I can find a computer fast enough to actually play back full-quality DVCPROHD. It's harder than I expected!

As for the DVD, miniDV thing, I was uner the impression that DVD was 4:2:0? So I'd be losing vertical resolution but not horizontal? Relatively speaking anyway, since SD would be a huge loss anyway. sniffle. But the real reason I think for DVD now that I look over the stuff in more detail is that they have an HD upconverting DVD player while the DV deck just seems to scale and it looks ugly! eww.

Finally, my hopes for the HD-DVD was that I could put the data on a standard DVD-R. For short films, supposedly, you can author a 25mbit mpeg2 like on an HD-DVD to a standard DVD and HD-DVD players will play it back as an HD-DVD. sweet! Haven't tested it tho since I have no player!

Also, the department didn't really encourage shooting in HD. They did buy the cameras, but they don't really seem to understand it. In fact, they don't even recommend shooting in anamorphic 16 by 9 if people shoot DV. They think letterbox is better... sometimes I can't deal with them. ugh.

Anyway, it looks like you all seem to think that the computer woudl be the best bet. Maybe I'll get ahold of one and try to prove to them that it will all be super-fast and flawless! You'd think that if anyone would appreciate the value of showing a film in its native format, it woudl be the film department! lol

Thanks,
-Colin
