Procedure for uprezzing 4x3 letterbox to 16x9

Re: Procedure for uprezzing 4x3 letterbox to 16x9

a question: we're considering using two cameras on our shoot, but we have only one 16x9 adapter at this point. do you think there's a way to combine footage from the two cameras if they don't both have the adapter? or do we need to get an adapter for the second camera as well?

thanks.

use the non adaptor for CUs and ECUs and the adaptor for all wider shots. you will get the best of both worlds then.

will there not be a difference in quality (resolution) if i do that? also, would there be a difference in terms of getting this footage into the computer? wouldn't the Anamorphic stuff look squeezed if i brought it in in 4x3? i just haven't used one yet so any advice would be appreciated.

thank you.

pashapasha:

If I may suggest, if you don't get the response you need, consider starting a new thread here in Technical. Your question is only very indirectly related to this topic of software uprezzing. (i'm intersted in learning the answer, too.)

I have read the discussions about the PAL system, but no one specified any dimensions. Or the procedure they went through.

I don´t really know the dimensions I should use, that is why I ask.

Hi all,

I've been following this thread with great interest for use in my documentary. A question was asked earlier that I would like to re-ask:

Would creating an uprezzed version to HD using Photozoom Pro be desireable - lets say to 1280x720 so that it can be output to a Panasonic HD Deck using firewire? And would it require significantly more render time?

Thanks,

Lane Wyrick

Disjecta,

Have you uprezzed everything on Pine Lake Film's website by your method described here or only some of the scenes in those films? What about your "Being Desjecta" piece?

If working with a much longer film, would there be merit in saying to oneself "I think I'll pick this scene and make it come through with outstanding resolution" and then let a few others just come through as they would on their own or do you spend the process on the entirety of the film?

just curious. thanks.

Hi Everyone,
I'm new here and I'm sure you guys have already discussed about this, but I'm shooting a short that we don't know if it's gonna be transfered to film yet, that is still on hold. I want it to be seen as the good and old 1:1.85 on TV like it will be if I transfer it to 35mm. My question is: should I shoot letterbox, since there's only a slight possibility of transfering it? :-/
 
Hey, finally found this thread...Barry_S helped me out!

Anyways, I have a big question for ya'll...

I just uprezzed a few pictures just to test it and each TIFF frame was 45 megs after uprezzing. Now, to uprez and entire video (clocks in at 4:03) , I'd have to have over 260 gigs JUST for the pictures...that's insane.

Am I reading this right? Or is there a better way of doing this?
 
Brandon--If your uprezzed TIFF files are 45 megs *each*, then something is horribly wrong. A 720 x 640 or 720 x 480 uncompressed 8-bit TIFF should be a little over 1 meg.
 
Barry, thanks for the reply.

Yah, I figured that was wrong...what are the settings in Photozoom Pro, then?

Right now I'm exporting the TIFF files at 0.99 MB out of Premiere Pro.

I go into Photozoom, load them into a new batch.

Settings:

Pixel size:
720 x 640 pixels
Print size:
10 x 8.8889 inch
72 dots per inch

Hmm...already that seems lower...something must have happened last time?

S-Spline
Generic Default...

Okay, I'm going to run it

Hmm...it's going alot quicker now.
something must have happened with print size, as last time it was damn near 80 inches!!!

I think it's going to work this time!

THANKS A TON BARRY! Two different days, two times you help me out...I feel I owe you something!
 
Hmm...now the pictures are interlaced...even though I shot this test at 24p.

Here check it out...

Man, I have to think before i post...

When I fix one problem, I create another one...and it's easily avoidable.

I think I have it fixed now, I'd like to thank you Barry again.
 
Ok, I'm trying this on my Mac and having some problems when I get into longer length videos. I'm trying to uprez a 15 minute short, which consists of 22,000 frames. Whenever I import the uprezzed images into Quicktime Player as an image sequence, I can never fully export the video as a Quicktime movie without it crashing on me, sometimes right when I export it, sometimes after it is "done". The Quicktime movie it creates is completely unusable and contains no data.

I'm on a dual 2.0 G5 with 2.5 GB of RAM, so I don't think computer power is the real issue. Restarting doesn't help.

Is there an alternate way to import image sequences? Can it be done in Final Cut?

Edit: I'd also like to add that I have successfully exported movies from image sequences for shorter videos, 5-7 minutes in length. It is only with this one that I have had trouble. I'm planning to do some longer videos rather soon, and was hoping to do this instead of buying an anamorphic adapter, but now I'm not so sure.
 
hope i don't repeat anything here...

but do you have a setting that can be used for PAL users?

ATM what i have done is

export a 4:3 image into AE - cropped the size to 720*405 and then in photzoom increased to 720*576 - rendering now to test

but i was wandering what I would use if i used squeeze mode and if i used non squeeze mode (without the step of cropping in AE)...

lastly - i am using PNG - from what i hear it is lossless - so should be just as good as TIFF any opinions?


EDIT - regarding the QT/FCP issue - when i last used FCP 4 - there was no option to just import an image sequence - have things changed with 4.5/HD?
 
I'm bumping this back up to the top and requesting that it gets reinstated as a sticky...I'm receiving a bunch of emails about it and it's hard to find it in this forum.

Thanks

It works exactly the same way as footage you would get from the anamorphic lens. It will look vertically stretched on a 4x3 TV and will be the correct ratio on a widescreen TV.

When you burn it on a 16x9 DVD, it will display correctly on your 4x3 with a letterbox mask and on will fill the screen of a 16x9 TV...

I have tested it on both and the letterboxed image on a 4x3 TV is stunningly clear. Aside from that, all of my tests were done with a widescreen plasma TV and it also looked great on that.

This is the first time I have responded to a thread of yours, so let me add my compliment to the many others regarding your work. You mentioned burning a "16x9" DVD. How do you do that? I use Idvd personally. Do most programs allow you to make a choice about aspect ratio prior to burning? By the way, my family originates from the Northwest. You might want to venture into Skagit County, about 1 hour north of Seattle. Great opportunites to film geese and tulips during the annual Tulip Festival.
 
I don't know if IDVD supports 16x9. You would have to specify it upfront in your project settings so if you don't have that option, then you can't do it.

You should look at the documentation or help files that came with IDVD to be sure.

Thanks for the compliments, btw :)
 
Hi,

This techique for uprezzing is exactly what I need - thank you for bringing it to my attention. I have tried it though and encountered one problem: My final footage is exactly as it should be in every way EXCEPT there seems to be an interlace problem. The shot pans slowly past a number of people meditating and the edges of their body images in the frame waver a little with that interlaced look.

Do you have any idea what is causing this problem or how to fix it? Thank you!
