uprezzing

It an interesting result and I know nothing of PhotoZoom. ( I checked their website) but want tknow a bit more before I look at the Trial vers.

How would one output 1000+ sequential frames (of lossless DV avi from an NLE via PhotoZoom ?

Does it do anymore than just zoom and re rez the result ?

Film scanners (Digital to film output) have very specific frame sizes and requirements. Can Photzoom produce files such as these ?

Can it deal with the various Pixel Aspect Ratios from DV sources ?

It is a two step process-
1. Export from your NLE an image sequence in the TIFF format.
2. Using PhotoZoom Pro you would then convert the TIFF's into the size that you need. (It will do batches at a time. and I'm not sure if there is a limit.)

From what I understand: NO. It does one thing, and only one thing - resize your image without loss of quality. (or very little loss). But it does this VERY well.

YES. Again from what I understand you specify the output size and it does the rest.

YES.

This is what I gathered from their web site and from the 4:3 to 16:9 Sticky thread. Hopefully those with experience with PZP will either correct me or add to what I have said.
 
I did some tests using the trial vers PZP to approximate what I did with After effects.

Namely re comp a DV frame to a frame for a Film Scanner. I used the example as above of the chart. and resized the image to 1828 x 988 pixels in PZP and previously in After Effects.

Conclussion (and my opinion only for what its worth)

PZP does not have the re -rez functionality to a film out put task (unfortunately) - it is designed around Print (not video) and uses print terms. But it does have some great 'sharpening' technology that works brilliantly - but maybe with a bit of "fakeness" ( fine on a graphic chart but not so "filmic" on a real subject )

Resizing the chart image from the 720 H px to the new dimensions took 1 minute 07 seconds to "render. That would be almost 30 minutes to do just one second of video . ( By comparison After Effects did 1300+ frames ( 45+ seconds of video) for my cinema project in approx 20 minutes)

PZP created files that were 8.2 mb each frame. AE were 5.2mb each frame

PZP frames appeared sharper apparently but some of this was "added" contrast (black increase). The edges were definitely sharper as were the artifacts.

I could not find a way to Unconstrain the format ( aspect) or position (compose) the video frame with in it. eg 16:9 aspect or 1:185

Note that After Effects worked with the original DVavi file without an intermediate seq. tiff files. (AE rendered to seq. tiff files).

I do think it is a desktop technology of the future for DV. The motion film labs already use some of it combined with grain filters etc in their film output process.

I know I could find a use for it in one of my projects. eg A shoot on DVX with frame grabs for an accompanying book.

Just my thoughts...and I wonder what others will use it for ?

Those are some pretty big differences, both in time and in file size. Thanks for the update.

My guess is that people will use it (PZP) who want a better quality then the NLE or PS can provide, but don't want to shell out the extra money for AE.
 
better quality for what ? ... screen grabs maybe ?

After seeing the TVCs I shot on my DVX102a output to 35mm film (via AE) and projected, my eyes opened to further possibilities . One option being to to improve further the results I actually got and as mentioned - it surprised many. I have a 35mm film DP background (plus previously (recently) owning a film laboratory as a string to my bow). I was a sceptic and very anti "video" until my paradigm shift.

The DVX images amaze me and if a piece of software ( eg PZP) can make further quality gains... I will be looking at it .

Good Original Post - somewhat hijacked (but we all learn)
 
a few things, now that there's been a billion responses to this (btw, thanks for all the screen shots, they were really a lot of help):

some people were suggesting to not uprezz at all. i'm submitting this to film festivals, where it will probably be projected from DVD, maybe beta SP. if left in 4:3, will it look like a 4:3 project with black bars (yielding a mini widescreen view within a large screen)?

when i scale the footage in premiere pro, then export it to an .avi, the computer still recognizes it as a 4:3 video clip in the settings (and therefore, encore dvd thinks the same thing). how can i change the imbedded aspect ratio in the file? does this problem occur with any of the other methods of uprezzing?

i'm also curious, where does the word "uprezzing" come from?
 
Ryan,

I'd like to do a test in Digital Fusion using some methods I have here, what resolution should I send you a sample ?

Thanks,
Ulisses

YEP. But most will probably think it is widescreen because they are used to seeing those bars.

I do not use Premiere, so I can not help you specifically (I'm on FCP), but in FCP there is an option to change the sequence settings to 16:9, it is a little box that you check. The computer then marks it as widescreen, and the DVD encodes properly. You might check the preferences, or in the settings to see if there is an option like this ...

You are changing the resoultion (screen size) of the image, and in this case you are going from a smaller resoultion to a larger resolution, you are going "up" in scale. So in short you are "Up-Rezzing". It is a slang term, used for short hand communication.

Sounds great.

Send in whatever rez the file is natively in. Other then the AE still, the others are in 720 x 640 . This is the native uncropped version, so if you could send it like that, it would be preferred. But as you'll notice in the FCP still, it only outputs at 720 x 480 (for DV).

Does that make sence? Or am I being as clear as mud? (I just got back from a long drive, so I'm a little out of it.)
 
So I can scale your original test image to 720x640 ? How can I send you the image, PM, email ?

Thanks,
Ulisses

Yep, Scale the original image to 720 x 640. Either PM or Email will be fine.
