Quick Question About Unprezzing HD

I am new to the whole idea of unprezzing your sd vid to hd (still don't quite understand) I am doing music videos and commercials now, but I am about to do a short, and unless I can get budgeting for an HVX 200 (I currently own 2 DVX 100B's) I would like to try and utilize this unprezzing method (yes I understand it will not be completely hd). My question is, adobe premiere cs3 has i set up where you can exort your sd vid to blu ray and hd (however it just seems like they are only raising the mbs per second beyond sd constraints and making the size like 1260 x 720) So, how does this premiere method work compared to other programs or plug ins (such as the instand hd plug in). Thanks ahead of time guys.:D
 
I think there are two ways to do this and I have done both and had success.

One is Instant HDplugin from Red Giant.

The other is up rez in AEFX. (Import the avi into an AEFX HD Comp and scale it)

...and actually it will be HD even though it was not shot on an HD camera.

Ok I assume you're saying import your normal avi into after effects put it into an hd composition scale it up and then it should be hd compatible.

Well let me ask which one you think works the best.

1, The aforementioned method

2. Instant hd

3. Just exporting directly from premiere using hd export settings

4. or using a program such as procoder using hd export settings
 
I only have experience of 1 & 2

Both worked and I chose each method more based on workflow convenience at the time. I had no reason to do a substantive or qualitatve test because the results were fine (I went to Broadcast TV with them).

I suspect both to be better than #3 because I surmise that AEFX has better scaling algorithms and Instant HD claims a scaling technology also. Any Premiere scaling always appears to have obvious and logical issues.

As regards AEFX. I have also out put PAL DV to 1: 1.85 Film out put for Cinema Prints from this technique. Results were surprisingly good. In fact - amazing. In this instance I output seq. tiffs for the Film Scanner to use.
 
Thanks alot, I'll probably get a couple of shots myself and test method one and 2 and get back to you. Couple quick questions though, after I export the avi, I'm assuming I would create an hd template in encore then render that file out and also how will the footage appear on a standard ntsc (720 x 480) screen
 
Encore? It's a DVD author program and it just won't accept HD footage at all, period. In fact it won't accept any file size other than 720 x 480. You're not going to get HD footage onto a DVD anyway.
 
my encore cs3 has blu ray authoring, I assumed it should be able to handle dvd. Well what dvd authoring program should i be using for my unprezzed hd footage
 
Encore CS3 supports blu-ray, but what you're trying to accomplish is unclear. I don't know why you'd try to uprez SD footage, then burn a DVD, which can only be 720x480. I could see if you wanted to uprez your project for internet viewing, But going back to DVD makes the whole process seem pointless. Unless you're doing a slight uprez to get a widescreen DVD out of a 4x3 project. And I don't think and uprezzed SD project, burned to bluray, would look any better than an SD project displayed on an HD display.

I guess let me clarify, it is a certain thing called hd dvd. I know one of my cameraman put it in my mind about unprezzing the sd footage, because I was never completely familiar with the process. My plan was to shoot in 1080 hdi or whatever you call it with the HVX 200. Since I wouldn't have the HVX 200, like I said one of my camera people told me a cheap substitute to getting 10810 hd I guess would be unprezzing your 720 sd footage. I understand its not a big deal with web upload I'm trying to firgue out how does the unprezz product work as far as a dvd goes or is unprezzing sd footage only for web formats.
 
Uprezzing and then burning to DVD is a waste of time because it just ends up downrezzing again into 720 x 480 anyway, and you may actually end up with worse looking footage.

And hardly anybody post HD material on the web as it takes very long to stream or download.

Digitally uprezzing is always a waste of time IMO. You can't make up information that aren't there and it's never going to look as good as the real thing. Even with native HD cameras you can see flaws when the footage is played on a decent HDTV, so SD uprezzed is just not gonna hold up. The purpose of uprezzing programs is that if you have one or two SD shots that needed to be matched with an HD source; the real HD materials would hide the imperfection of the uprezzed shot.
