uprezzing 720 to 1080

[Emanuel]

If we are interesting to mix 1080 with 720p for the variable frame rates for a final 1080/25p, how is it the best way to uprezzing 720 footage to 1080? Any hassles to handle with it?

When uprezzing from 720 to 1080 will be a lot of noise, I think.:cry:

Don't be in panic, Danilo!...why will it be so?

It's like photoshop, you know? When you uprezzing an image it surely shows artifacts! Don't you think? Often I think is very hard to reach organic characteristics of film, it's like a challenge of human skin versus clothes, human skin is beauty because it's organic. Film is like human skin, it's soft and warm.
Digital world it's more simple to make, to control, but when we want control all this digital stuff, it also show its limits.

Don't you think caro Emanuel?

Don't you think caro Emanuel?Yes and not necessary. There are different media but the convergence is not out there by lucky. On the other hand, the HD digital environment is so unique as the film one. It's just another form to see the reality or to make the imagerie. When you are saying that «it's more simple to make, to control» it's not bad at all but for sure you touch its limits easily. But if you control...

Last but not least, trying the film-look is not so unacceptable as some people would like to make as general truth. But there isn't truth owners. Otherwise, it's merely a question of taste to partake.

If you send me a file or DVCPRO-HD tape somehow, we'll uprez it for free at my friend's place in L.A.

Well if you watch 720 on a 1080 LCD monitor then the monitor will do the uprezzing for you. So it's going to happen whether you like it or not. Right?

In audio editing they sell special CDs that just contain noise. These CDs are used when performing some types of processing to reduce artifacts.

Jerseymike,

Do they use the noise CD's to remove noise, as in noise cancellation, or do they use them like room tone, making the cuts less noticable?

[JerseyMike]

I believe the noise CDs are used when dithering 24-bit audio down to 16 bit. Apparently the noise is mixed with the original signal to toggle the least significant bit before you cut off the extra bits. Here's a link to one:

After reading up on it I don't think the concept will help with uprezzing, but maybe with downrezzing.

Also, I've never used one for dithering so I can't share any first-hand experience.

I believe the Algolith plug ins are among the very best scaling algorithms out there. You can buy a full license that runs for a week for 59 dollar. Thats more than enough time to upscale even a feature film :-) One downside is that this works like an AE plugin, so it will only work in RGB (Still works in FCP though) This means that you'll have an YUV>RGB>YUV conversion step if you aren't going for RGB output (HDCAM SR)

For normal editing, an application like FCP 5 does pretty good YUV scaling, and it works automatically when you drop the lower res footage into a higer res sequence. But you would have to render the segment, if you drop 720p footage into a 1080 seguence, because the two format uses two different QuickTime codecs (DVCPRO HD 720p60 and DVCPRO HD 1080i60)
