8-BIT, but higher FPS

Spark Series
1

Would it be possible to get higher FPS at lower color bit depths?
Similar to what Chronos 4K12 does.

This would be extremely useful in controlled experiment scenarios where colors might be not as important as having higher FPS.

Any info on 8 bit to get even higher fps @admin and @young?

@young @admin can we get a response to this please?

Not sure about bit depth, but in Philip Bloom’s review, he was able to get higher fps with custom resolutions, essentially the lower the resolution, the higher you can go.

Looking at the specifications of the Gsprint 5514 BSI sensor, if that is indeed the sensor used in this camera, it is possible to change it to 12 bits and increase the dynamic range from 62db (over 10 EV) to 67db (over 11EV) and limit the fps to 350. I think Pixboom mentions this option to implement it in their camera. 
Furthermore, the sensor also has the ability to limit the frame rate to 80 fps, which gives us 12-bit HDR and a dynamic range of 78.3db (around 13EV), but Pixboom will probably not implement this mode in their camera.

Unfortunately, there is no mention of 8-bit mode, so I assume that it will not be possible to limit the mode to 8 bits and then increase the frame rate.

By the way, @young, could you confirm that your camera has a GPSRINT 5514 BSI sensor?

We won’t be supporting an 8-bit mode. We found the noise performance to be very poor, making it unusable for content creation. Our main focus for development moving forward is on the 12-bit mode

Thanks for the direct answer.

Sorry, but we can’t disclose any information about the chip selection at this stage, as it involves a confidentiality agreement.

Thanks for your honesty, @young. Once the cameras have been sent to the first customers, will you disclose the brand and model of the sensor? Will this happen later? Or are you not planning to do so at all?

Any chance you have sample footage of 8-bit somewhere?

In some cases noise might be totally acceptable if we would end up pushing to extremely high fps. 
Ability to see super fast events in lab settings might be more important than ideal noise performance.
Even when posting on YT, IG etc…

Plus NR can help a ton maybe in some cases?

I totally understand if this is not a priority at this point, but in case you would like more feedback and possibly review of test footage of 8-bit I would be gladly to help, and probably others here as well.

Unfortunately, after our evaluation, we selected a sensor that doesn’t have an 8-bit mode. So it’s a confirmed hardware choice at this point :wink:

Haha, we’ve got to keep a little mystery.
