2K Scaled Is Vital

[Hans von Sonntag]

This is a R&D request that I humbly bring up because I came over it in a real world situation

As Matt Uhry mentioned somewhere there is some serious need for 2K scaled. Yes there is and we badly need it.

The reason:

2 days ago I shot a commercial on 35mm with 50fps all day. Delivery format will be Pal 576i. HD for broadcast is not there yet, an won't be in the next 5 or even 10 years at least here in Pal-World-Europe. Things are interlaced and sometimes need interlaced footage.

1. Often pans (range pack shots for instance) have to be smooth and for that reason they need in PAL world interlaced footage. 35mm is frames only and so is RED. If you want interlaced/fields you have to shoot 50 fps.

2. Some action has to be shot in 50 fps for slow-motion shots, you need that every day on a commercial shoot.

3. Depth of field of 35mm is compulsory.

Now, shooting 4k is great for quality and depth of field but cannot over-crank up to 50 fps. 2K windowed can do 50fps but does only use a portion of the sensor, hence the DOF of S16 which is not an option for serious commercial work.

As an extra benefit there will be more runtime and transcoding will be faster.

We need badly scaled 2K!

Please make this happen, for me personally much more important than on-board sound for instance... nothing against on-board sound though.

2K scaled with higher FPS is what many would love to see.

I believe you can shoot 2k in camera with 35mm lenses that will fill the 35mm sensor but it will save it as 2k

Not at the moment you can't. That is what this thread is requesting. Currently 2k in camera is derived from a 'window' in the centre of the sensor, the size that would be covered by a S-16 lens, even if you are using a 35mm lens.

How many times does Red have to say that 2K Scaled higher than 30fps IS NOT POSSIBLE due to the processing power needed to pull it off. It's not going to happen on Red One according to them. Red Two maybe?

Well, but 4k does not work at 50 fps which is what he wants to generate the interlaced PAL video (50 interlaced fields per sec).

Interesting to think of shooting 4096x2304 pixel frames and scaling down to the PAL field which is 720x288 pixels! That would be an oversampling ratio of 45:1. A bit less if you're cropping the 4k for 4:3, even a bit more if you're broadcasting 16:9 letterboxed.

Well, it is for movies like Zodiac.

As a commercial Director and shooter I could not agree with what Hans is saying more. I have said it before, I would take scaled 720p if that is all we could get to have more framerates with the full sensor size.

thanks Red team I know you guys are listening.

If you need to bin sensor photosites do it, whatever it takes to get a clean 720p or higher image with full sensor size.

If you had the RAW port, you could supposedly shoot 4.5k up to 60 fps, and do the processing elsewhere. I just can't imagine anyone finding it worthwhile to do so.

Yes, for Zodiak and many other film shot in S16 or 2/3 Video. But not for most commercial work. Horses for courses.
