We have a 1.89:1 as a standard (so for 4K it would be 4096x2160, for 2K 2048x1080).
Then we have other standards: 2048x858, 1998x1080, 4096x1716, 3996x2160
RED files shoot: 4520x2540 (1.77), 4480x1920 (2.3), 4096x2034 (2), 4096x2048 (2).
None match with the DCI specs. Normally 30fps at full res for Red and progressive.
I think that Avid is the only NLE, the MC 5 that can actually support the RedRocket card, if I'm wrong please correct me.
I'm not sure about the FCP with native Red files wich is somewhere a non-sense (if it can't but again I'm not sure, I do not use FCP) because FCP is a "standard" in many prods but if you're lucky enough to get Autodesk Smoke then you're safe with latest version.
Does Smoke runs with other NLE ? it does not to date that I know. It's a modern powerfull complement married with an outdated NLE and we don't know what Apple will do.
Why do we still have interlaced ? Does that make any sense today ? But we do have to deal with it. One standard interlaced, the other one progressive.
ARRI is FF 35mm at, (arriraw), 30fps wich is to me more into the tendency we will need because I beleive like BC that we'll have, or we'll need squared standards very soon because of the evolution of medias displays and distribution and because of the need to get one material for both stills and motion.
The good think about the PL mount is that you can mount via an (expensive, about 300-400euros) adapter to Canon 35mm or even Pana GH (but then remember the sensor is smaller)
In all that simplicity and field of clarity you can create a funny frame composer in Arri website for ex according to the jungle of formats that can be required. That's very practical but it also mean that you actually loose part of the sensor recorded in the area virtually cropped.
Red algorith is not lossless (although I think it can be considered lossless) while Arri is, all the other shooting codecs that aren't RAW aren't lossless. It means that the degradation has to be stopped at the stage of editing.
The obliged debayer path for raw video is tunable according to where the footage has to go on the chain, so again, convertions and convertions and more convertions at any stage and that is true whatever the system is.
One for shooting, convertion(s) for editing and zillions possibilities for the delivery.
Europe broadcast is 25fps, US is 30 cine is 24 or 48 and they want to go to 60. Why "or"? and why this silly 24 that belongs to the stone age?
That means that you have to have a master edited and then dispaches to this and that. More rendering on the chain.
Broadcast compress to standards, cine is flexible and adaptable. Broadcast cine-orientaded is full hd while sports-orientated is 720.
I do not have 2 technical sheet for clients that are the same in terms of requirements except the size and generally the sound bit but not always. That is why I'm going crazy and I'm not the only one.
In the case of an inter-frame compression wich it's been regarded as the new holy grail because it has a higher compression, if for a reason or another, the single frame is lost due to a tech issue (and it happens), the all group of frames that belong to it is lost. I'm not sure every expensive prod is willing to take risks on such a fancy stuff and actually they do not.
Not 2 NLE handle the same way the AVCHD editing (wich is absurd editing in this format). Avid is truly workable and Premiere much slower (at a same computer performance).
Converting to a lossless editing is different if you are on Mac or PC, and there are too many choices. So yes, it's stick with one like prores but not always you can export with prores. It's like you won't be able to export a Tiff on a PC.
At first the 5D2 only had 30fps, (europe is sometimes difficult to find on a map fron Japan) then they finally released a 25fps and joined the SMPTE time code standards not without vacillations.
Etc...etc...etc...
It seems that every brand has its own vision, it's own solution, while standards are been established in a great confusion that probably will not match soon anyway the needs of publishers with the new medias and will be again in another mess.
http://www.dcimovies.com/press/Please, if I made tech mistakes in those lines I'm writting while I'm actually render with a fancy codec that will probably be obsolete tomorrow morning, correct me.
I'd just like a little bit more simplicity.
