Open Gate in 4K instead of full sensor resolution

With the C50 getting 7K open gate and C400 getting 6K open gate recording modes. I hope Canon implements a 4K open gate mode in future with the possibility of higher frame rates than 30fps.

I have to say that not having open gate support coming on my C80 is incredibly disappointing. I often need to shoot in 16:9 and create cuts for 9:16, so this form factor is very desirable. I don't understand Canon's logic in offering this feature in the less expensive EOS C50 and R6MarkIII while completely neglecting the C80, which is a more expensive and capable camera. Given the data limitations on V90 SD cards, why, Canon, would you not include a CFExpress card instead of dual V90 SD cards in the C80 to begin with? Was Open Gate a complete surprise? Surely your talented team can offer an all-intra or log-GOP based solution that would support the full sensor res but export to a compressed codec instead of RAW. Or at the very least, to help us not feel completely overlooked, offer Open Gate support via an external HDMI recorder, like you do with 6K RAW at 60fps? I appreciate that these solutions will take some time to figure out but it would be beneficial to let the community know that you are working on this instead of "sorry the C80 only gets view assist playback (oh yay, it should have been there at the beginning) while everyone else (EOS C400, etc) gets the super useful Open Gate" in your next firmware update.

Greetings,

I think all of this comes down to a design decision.  The C80 does not have a CFB slot, and thus cannot record open gate reliably to.lower bandwidth SD slots.  While it uses the full width of the sensor, it does not use the full height.  With the C50 and C400 both having or getting this option via firmware, I think the chance that the C70 will get it is low primarily due to hardware limitation (first) and product segmentation (second).  Recording bandwidth is already at 80mb a second.  There's a chance for discrepancy in recording capability between different brands of cards and Canon can't risk users running into buffer overflows when using cards that can't sustain high bit rate recording.  Could recording to an external output be possible, maybe.  

I understand your sentiment.

Hello, I appreciate your point of view, however, regarding segmentation, the C80 is a relatively new camera, so it seems counter-intuitive that the C50 and R6MkIII and C400 would all be in segments that include Open Gate? The C80 is a perfect segment for this feature, but it appears that Canon hasn’t foreseen this with its decision to keep the dual V90 SD cards of the C70. I have one of these as well, and would love to see 4K Open Gate supported with its smaller sensor, and the bandwidth of the V90 cards should be adequate. With the C50, this supports 7K Open Gate in RAW as well as in compressed HEVC-S format. The HEVC-S format only requires 480Mbps of bandwidth to store on its cards, and the C80’s V90 cards can handle up to 675Mbps, and given that the C80’s sensor is only 6K vs the C50’s 7K, there should technically be more than enough bandwidth for a compressed Open Gate feature. With the C70, and its 4K sensor, again, it should be able to support a compressed Open Gate capability. Canon, if you’re listening, please make this available in a future firmware update so we can make the most of our amazing C70 and C80 cameras!

It has been proven that the limiting factor isn't because of SD cards, because you can actually record 7K 30fps open gate in XF-HEVC S to the SD card on the C50. (take a look at Video Recording Configuration section
of the C50 user manual)

Which makes me wonder if Canon is deliberately limiting the C80 for market segmentation? 

Whatever the reason, it doesn't make sense for the photo camera R6 III to have open gate but not Canon's own Cinema camera C80.

I can't imagine what Canon's logic might be for limiting the C80 due to market segmentation - you get Open Gate in less expensive cameras, as well as more expensive cameras, just not it.
