Odyssey7Q + FS700 - 4K Modes

Dear Friends,

I am again asking for input from the FS700 community.

The Sony FS700 can output 4K, 4096 x 2160 photosites, I will call this 4K in this thread.

The Sony FS700 can also output Quad HD, 3840 x 2160 photosites.

....Some call Quad HD "4K", and consumer 4K televisions use this mode, which professionals, in my opinion, call Quad HD.

Quad HD has many advantages as it is the format that consumer televisions use, and it is easy to get HD out of Quad HD, if desired.

Quad HD 3840 x 2160, has 6.25% less horizontal photosites than 4K, 4096 x 2160.

We feel that a majority of FS700 users will shoot in Quad HD (3840 x 2160) for a variety of reasons.

When shooting for a theatrical release, 4K (4096 x 2160) may be more common.

But, we like to get comments and suggestions from the FS700 community.

Our goal is to decide which mode to implement first for our Odyssey7Q.

We certainly plan to offer both modes, but we need to provide the most popular option first.

Thank you for your comments.

Respectfully,

Full 4K first. If I make the decision to shoot in an ultra-HD format, I'm going to go full 4K. Those 6.25% of pixels aren't going to make too much a difference in filesize, and I will have a small latitude to reframe shots in a QuadHD project.

However, if QuadHD is easier to implement for you guys and by going that route means you can have QuadHD available at launch, then I don't think many will complain, just as long as full 4K isn't long behind.

Quad HD for sure, especially if it's more HD and TV friendly and it scales down to 1920 x 1080 easily while true 4K does not. Everyone has the fantasy of being a "True" filmmaker and needing true 4K specs for theatrical release, but lets face it, most of the FS700 stuff is for TV or Vimeo so why not use the medium that is most friendly toward that? Which is Quad HD.

Also, doesn't the FS700 LCD have issues with framing true 4K since it's a different aspect ratio?
 
Full 4K please.

If you shoot 4K it's with feature film in mind, even if you end with a 2K DCP.

I also hope that Sony will let you (and us) record 4K RAW in the future...

As a person that has months of commercial and music video work lined up, QUAD HD would be my main form of use for the Odyssey.

why dont you shoot 2k or even 1080 Raw for this purpose, at least until implementation of Quad HD is ready?
Dan asked what they should work on first.

this reminds me of the comic bit ,with the devil(my ego) on one shoulder saying ,I WANT 4K NOW, DON,T BE A PUSSY ! and then the angel on the other shoulder who also happens to edit . WELL IF QUAD HD COMES IN A EASIER WORK FLOW , ok so ,more is more , 6% ? if the absolute best full 4k is splitting hairs ,better but comes with a tougher knock down to be delivered now to my customers . quad hd just is not as sexy as full on 4k to our customers . the last time these to where arguing on my shoulders it was about buying my lotus espree , with the dude in red tights saying .... DON,T BE A PUSSY ... YOU NEED THE CAR TO GET TO WORK ON TIME!!! this time my vote is for quad hd now .
 
Dear Friends,

Thank you for your votes.

The voting is still open.

While we can debate and decide these decisions ourselves, I just feel that it is better for us to implement what the majority of our potential users want first.

I think if you are shooting for yourself 4K is fine, but for paid jobs Quad HD would be much more desired.

Quad HD has plenty of crop space / repositioning since it's an HD finish for pretty much all paid work with the FS700. For an Alexa or RED since they are used for theatrical release 4K is probably more optimal, but the FS700 is stuck in TV land for the most part. Now that Im finally getting some network jobs, I know my broadcast TV clients would 100% want Quad HD every time, especially if they are viewing the feed live on set since want they see is what they get; and for faster / easier / less decisions workflow in post

I might be inclined to use 4K if there were HD markers on the FS700 LCD or the 7Q, but otherwise you don't know where the exact framing is while shooting. On my bigger set jobs, I've noticed that I mainly just use the EVF / LCD which is wired to the Small HD DP6 on a light stand that is for the director which is then wired out to a large monitor for the clients and producers in the viewing area. So since I work with the onboard LCD 90% of the time, I would need 4K markers on the LCD as well as 4k markers on the 7Q and the clients monitors. Seems like a pain.

Does the FS700 have 4K / 2K markers?

On another note, I would probably only use 4K or Quad HD for the occasional green screen or VFX shot. Most of the time it would be 10 bit 4:2:2 HD, so maybe this doesn't apply to me much. But yeah, still way prefer Quad HD to for workflow reasons.

To actually resolve true 4K resolution without aliasing you need to sample from an 8K sensor (F65 comes close). While a chart test will show us real world results, IIRC, one of the Sony experts stated the FS700 could do around 3.2K in 4K mode. If accurate, quad HD makes more sense as full 4K wouldn't contain any more resolution, wasting disk space and requiring rescaling in post (extra processing time).
