Sony FS700 getting S-Log

..and the already announced ability to record RAW to the new CD Odyssey.

http://blog.abelcine.com/2013/04/11/nab-2013-sony-fs700-updates/

It's SLOG2 actually which so far from working with in on the F55 I think its better than regular SLOG from the F3.


Kind of makes the f5 obsolete doesn't it?

Not sure I'd say that. Consider on the F5:

- Form factor along
- HD / 2K 10-bit 422 XAVC
- SR Master Codec

But in terms of high speed frame rates, yes, it does seem the FS700 will do double the frame rates available on the F5 & the F55. lol
 
The FS 700 is already 10 bit 4:2:2 internally I believe. This turns it into an Epic without the crop factor for the high speed.
 
The FS700 is 8-bit YCbCr internal, and 12-bit RAW. The F3 is 8-bit internal as well and can only do 10-bit YCbCr or RGB through SDI port using an external recorder. The F5/F55 are the only PMW series cameras to do 10-bit internally starting at $16,500 and $29,000.
 
Wow, very nice. I wonder how much additional dynamic range SLOG2 will open up on the FS700?
 
I'm not so sure, if it can bring the camera up to 12.5-13 stops it starts kicking at the F3's door for DR. And that's nothing to shake a stick at.
 
Thanks for the link! Really informative, thanks to Tony Reale! I guess slog2 will also be enabled when shooting regular AVCHD? That would be really useful... I also wonder what other third party recorders will be capable of recording the FS700's 4K. did he say that the 422 out will get 10 or 12 bit with the firm/hardware upgrade/slog option?
 
This is great news! Slog is what was missing from fs700. It's was the only thing that was holding me back from getting one.
But I don't understand, is the slog going to need a hardware upgrade or only software?

It won't give any physical additional dynamic range, but it will make the range the camera is capable of usable. So you can argue that you increase usable dynamic range, yes.

The distance between shadow and highlight will remain the same. The 8 bit output is constricting it so much as to render the extremes useless.

I must sound like a broken record here (for those reading the 700 forum), for which i apologise, but i think it's important the people understand the distinction. You're not changing the sensor here.

It could be any of both:
* if SLOG is killing (not muting: killing) part of the DR of the sensor, the SLOG2 could bring it back to life and give you extra DR
* if SLOG and SLOG2 are both using all the available DR of the sensor, just assigning different final values to each input value, then, well, by definition it's the same DR
No idea which is the case in the FS700. I do know that in the Nikon D800 and D5200 a different way of transforming sensor values into codec values could give you 2+ extra stops of DR.

You can see 12+ stops from the paltry 8 bit range from the 700. But the upper and lower stops are next to useless for any manipulation. I don't believe there's anything beyond that. 12-13stops is more than adequate in real terms.

Slog will just distribute the values in a much better way

Sony's HXR-IFR5/AXS-R5 combo enables the recording of raw from the FS700 at 16 bits, but what's the point? Isn't the FS700 12-bit internally? That just seems like a whole lot of extra but empty data.

No one knows if it's 12-bit internally. There is no evidence/proof for that claim. The AVCHD was 8-bit and the uncompressed signal was also 8-bit. but it's unknown what the sensor is capable of after the firmware/hardware upgrade.
 
I agree with Tzedekh, the FS700 is a 12-bit internal camera and Juan keeps saying recodring at 16 bits with is true but its 12-bit at source.

If that "hardware/software" upgrade makes it 16-bit out, it will still be 12-bit on the sensor itself. Sony is certainly not replacing the entire guts of it for free or near free....

Admittedly the blog post is a year old, but AbelCine's Andy Shipsides says the ADC is 12-bit here (I specifically asked him):

First tetonsonthefly:

tetonsonthefly:
Is it really 8bit HD-SDI out? 4:2:? What is the point of having 3G then?

Andy Shipsides: It's 8-bit for sure, which is due to the Digital Signal Processor. The camera takes the 12 bit signal to 8 bit for the recording, doesn't have the ability to do 10-bit at the same time. 3G gives you 1080p output though.


And then me:

tzedekh:
Wait, I'm confused. If the 3G-SDI output is only 8-bit, will the 4K raw upgrade also be only 8-bit? Isn't that kinda pointless? What is the bit-depth of the sensor's ADC?

Andy Shipsides: The 4K Raw will be 12-bit, which is the same as the camera's A to D. Regular video will be 8 bit.
 
Yes, the FS700 camera is 8-bit AVC internal, 12-bit RAW via 3G-SDI. Someone in the forums have been saying the FS700 will be 10-bit... but the only 10-bit internal cameras start at the F5/F55 range. Even the F3 is 8-bit internal but has 10-bit SDI but it is NOT RAW it is only YCbCr or RGB capable.

Its seriously a shame Juan is going around saying the "FS700 is 16-bit" "the FS700 is 16-bit" - what a complete farse.

According to this interview with Juan Martinez, the FS700 will get Slog2 as well as the 4k output upgrade by summer. It will be a hardware and software upgrade, but he says Sony is trying to minimize the price. It's unclear if you can just get the Slog2 upgrade without the 4k upgrade. My guess is that after the summer, new FS700s will ship with these upgrades built in. Or maybe they'll just introduce a new model altogether.
