Highest Quality HD uprez for DVX ?

Curious if anyone has experience with this.

i've heard of "instant HD" and also know that you can "export / Quicktime Conversion" and choose an HD flavor... results vary. What about after effects ?

Or hardware based ? Example, going from a SDI out on mini-dv deck into AJA and coming back out onto HD-CAM ?

thanks in advance.

I'm not too familiar with that last option you chose.

I think your best bet is to export your piece as a series of TIFFs and take it to a professional post-house.

Well I know that getting the highest quality data off the mini dv tape is part of the equation. I question the ability of firewire to deliver the highest quality. I'm sure a better deck with SDI out captured directly to a high quality codec would yield better results.
 
I've heard of people doing up-rez through Shake before. I'm sorry I can't cite any specific examples, but hope it can give you somewhere to start. Some post houses use proprietary tools to do up-rez, so you would have to go through them to do it.
 
4:2:0 doesn't leave a lot to up-rez. After effects does a decent job. It takes a lot of tweaking, though. Paying for anything else seems kinda silly, unless you've got the next Zapruder film.
 
Does the color space affect that?

In which case, would having an Andromeda DVX exported as say like 830x1540 (1.85:1) TIFFs yield good uprezzing to 1080p?

Like, next to no loss in quality?
 
If you have chroma subsampling, you will notice it on an uprez, because you have such a small amount of data to begin with. If you mean 8 vs 16-bit color, you'll also see a difference, but not as much as the difference between 4:2:0 and 4:4:4.
If your original source is 1540x830 4:4:4 10-bit tiffs, then you've got 4x the luminance data and 16x the chrominance data of standard MiniDV, plus 4x the color depth.
As a comparison, the HVX has about 3% more luminance data and about half the chrominance data in DVCProHD 1080, and 1/4 the color depth, so I would expect that the Andromeda would give the HVX a run for its money in that case, particularly in colorful shots.
 
Thanks man. Appreciate your ability to give me the important info. in a terse, understandable way.
