  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Shootout: RedOne vs F35

Take into account that RED got the technology blueprints from 20 000 year old cave drawings from a civilization that was originally run by ailens with superior technology...

I mean, other companies just can't compete with that, simple as that.
Also why they don't talk about the mysterious sensor.

Hope I don't get in trouble for revealing the truth? :P
 
Joofa, that's where the magic pixies come in!

Combatentropy, I apologize in advance if the following message is terminology heavy but I wanted to provide a clearer picture why something more important is at play here and is not mentioned frequently, which Wavelet compression has taken advantage of very nicely.

Most Red users will be filming natural images. The power spectrum of natural images falls of more like 1/f^2, where f is the frequency, assuming that image statistics are at least wide sense stationary. For natural images, for which as mentioned, certain important image statistics fall off as square of image frequency, it will be helpful if we can capture this fall behavior using some ideally linear transformations. And, transforms such as Karhounen-Loeve / PCAs /etc., do capture this information very well, which is in accordance with certain Markov processes.

Wavelet processing is closely related with band-pass filtering, which electrical engineers have been doing for ages, and hence, such band-pass behavior ties in nicely with capturing the image power fall off, though, perhaps, not as ideally as KLT / PCA. However, it is reasonably good.

Therefore it is the properties/statistics of natural images that Wavelets is able to exploit more usefully than the often-used DCT/DFTs that are helping us here. On the other hand it is possible to provide example of images where Wavelets performs poorly because they could not exploit certain image statistics.

Oh, I see.........???
 
Useable resolution factors

Useable resolution factors

I understand lp/mm measurements for lenses and the need for optical low pass filtering in front of imaging chips whether CCD or CMOS based. What I am curious about is the relationship between them. Is it as simple as using a lens that exceeds a particular lp/mm threshold in front of the OLPF to achieve the maximum resolution of the system?

Are there issues with the size of the photosites in relationship to the OLPF and lens combo? Are aliasing and moire issues linked to the OLPF and algorithm designs only or does the lens play into that equation as well?

Joofa raises some interesting points about the characteristics of reflected light in real world scenes and how the mathematical representations of that image information may play to the strengths of a particular codec. I have surmised, though cannot prove, that some of the RedOne firmware iterations addressed idiosyncratic "codec killer" waveforms.
 
Form Factor

Form Factor

All of the serious D-cinema cameras can produce wonderful images with good lighting and quality lenses. I would pick the RedOne because it uses a large single plane sensor, is relatively small, lightweight and so flexible on set.

If you have seen the 4K reel that RED showed at NAB I think the image quality discussion stops with camera geeks like us. How about real world producer considerations. IMHO the RedOne is equal to or better than other options in these areas:

setups per day
handhold-ability with proper accessories
Steadicam friendliness
lens options
Depth of Field control
color information for grading
data rate to quality ratio
ready to edit

It is my contention that the remaining resistance to the RedOne in top end production environments is not about actual problems, its about perception and the security of sticking with what crews are used to.

Where do they live? Can I see them?

Well, I found them when I journeyed to the planet Mysterium, where they were powerless because of the blue star that the planet orbited. Jim designed special sun glasses for the little Mysterium pixies, and hence they began to work for us. Jim also designed special glasses for me, so I could see the pixies and communicate with them, to get them to live inside our cameras.

Hahaha, that was really very funny indeed :) I really laughed reading it.
 
...and the real reason for the fans inside the camera is to keep them comfortable? :)

...anyway they work pretty @#@# good.

Cheers.
