DVX to 720p

This didn't really get 720p because 720p isnt avalible on Avids system yet.
But it's still at HD resolution and the uprezed resolution is 1280x720.
It's done with PhotoZoom PRO and is a short file from an old movie I made.
It's just a few scenes cut together, no real cut, just a few clips to show the result and I think it looks pretty nice.

Hope that my filexoom account works this time...
 
This looks pretty damn good, a little noisy... but I don't mind that.

How does this work? Does PhotoZoom take a video file and uprez or is it a animated "pic" file (filmstrip, animated tiff) and up rez that?
 
Because my Avid sucks at exporting images, I exported a QT reference and in QT PRO export images as uncompressed TIFF individual images.
These are actually taken with a DVX100e, so it's not real 16:9.
First I did a batch in photoshop where I cut away the letterbox, making it a 16:9 image with false pixel ratio.

Then I did a batch in PhotoZoom uprez it to 1280x720 with s-spline. I finetuned the settings to get most sharpness without adding artifacts, then made some coffee. :D

After everything I started a 720 23fps project in Avid. I imported the images and then exported it to a QTref and with QTpro exported a H.264 QTfile.

Because current Avid can't handle 720 25p, the framerate is a bit ****ed up, but other then that the result is pretty good.
Even if you don't make it into HD material, you can import it into your earlier project and the result is much better, especially for DVD:s. Supercrisp sharpness and low artefacts.

I'm gonna do this with every movie I make, even if the process is long and diskspace gets low.
 
Thanks for the info. But I'm still trying to wrap my head around this...

So you end up with a lot if individual tiff files... so like a few hundred for a scene? That would seem time consuming if that is so, but I think possibly worth it.
 
No adapter, it's straight from a DVX100e and then colorgraded in Avid.
Each fram is uprezed individually in uncompressed TIFF format. There are 25 frames per second, that means 1500 frames a minute and 90 000 frames for an hour. Each frame takes around 3 seconds to uprez, so the final time it takes to uprez it is 270 000 seconds.

The storage space needed for 90 000 frames is around 236,7 GB.
So, buckle up your big harddrive and wait around 75 hours (!) for an hour footage.
 
very nice...and i have photozoom so i know what you're doing and how you feel about it...good stuff.
 
that was awesome! I WANT IT!! i have instanthd... i've heard it doesnt yield as good of results but i am going to give it a shot...
 
Here's a DVX100B with andromeda,


ontario lakes sunrise + some (what appears to be) rubber duckies. This is just 1 clip compressed with h.264 from pure uncompressed HD which started out at around 1500 x 900 resolution scaled down to 720p.

They are not though!

Don't mind the ending, this is what happens when you try to stream uncompressed HD to a hard drive that is out of space.

The unintetional ending reminds me of something that I'd do if I wanted to make a scene in a horror flick when a peaceful serenity goes BAD. :Drogar-Love(DBG):

Though the batch process of uncompressed 16 bit Tiffs is a lenghty process, it is not quiet as long as the one with the method described above. Just need to dump the RAW logarithmic footage, color corrected and dump it into quicktime.
 
Nice! I wish I had a DVX100B, but without money I stick with my DVX100E.
I loose a bit of the hight resolution when converting 16:9 letterbox to real 16:9 though.

Come to think of it... I wonder how many "usual" people out there that are able to see that this was uprezed. If they saw an uprezed DVX100 to 720p on a 720p lcd TV, will they really see the difference when watching MOVING pictures?

If not, then why bother with HDV, that has really bad problems when editing?
I mean, in progressive DV, you work with the images one by one.
Only HDV camera I can think of that really does the same is the JVC GY-HD100.

So why not keep the money and buy the "red" camera and continue use our beloved DVX. I don't see any reason for buying HVX200 if "Red" sticks with it's price.
 
Don't forget InstantHD, which is designed to do basically the same thing but without all the dealing with still frames. Red Giant Software sells InstantHD for exactly this reason.

Some people don't have $20,000 to spend on a camera. $3,000-$6,000 is much better for some people.

The process that Glazarus used is from DVXuser disjecta. A step by step walk through is found at http://www.pinelakefilms.com/uprez.html and is discussed at http://www.dvxuser.com/V6/showthread.php?t=6843&highlight=squeeze

we all know about the andromeda (well maybe not everybody) but the point here isn't really the time...it's a cost difference $3,000 vs. $49...hmmmmm...yes it's a different color space and all the bells and whistles, but i personally would like to keep my warranty at the expense of my own time rendering frames. :thumbsup:

Certainly, same applies to us, I can't afford to spend an extra hour a day in post production, it'd end up costing us much more than $3,000 before the month is done.

The only other thing up from here is a Viper Filmstream camera and that is much more than Andromeda. Maybe one day :beer:
 
I didn't read any guide about this process, I just used my photographing tools with video, which is the same thing, only smaller images.

But then again, InstantHD is for final cut (or after effects?) I edit my movies with Avid and there's no AVX with HD conversion. Especially when each project is handled with one format to maintain perfect quality.

I got drives and because the process is longer I can gain some extra bucks with people ordering an uprez. :D
