C80 - SDI output resolution during playback

kameraguy — Thu, 19 Dec 2024 00:18:53 GMT

Hi All, I just received my C80 and am learning it. I noticed something peculiar.

I am shooting in UHD 3840x2160 @ 59.94 fps. I have the camera connected to a Blackmagic Hyperdeck via SDI which is configured to accept this signal.

When recording footage through the C80, the Hyperdeck receives signal as expected.

However, if I playback the recorded footage from the C80, the Hyperdeck no longer detects signal via SDI.

In comparison, I have a Sony FX6 which I use similarly. And the Hyperdeck receives signal from the FX6 in both recording and playback modes via SDI.

It seems, the C80 does not output UHD signal through SDI when in playback mode. I could not confirm this within the manual though. I also did not find an obvious setting to adjust this. Does anyone have experience to know if this is normal behavior?

Greetings,

I'm researching this. Thus far I see HD output over SDI, but a 12G SDI can do 4k 60p, so I probably haven't found it yet.

Are you running The latest firmware? 1.0.1.1 was released today.

Firmware Notice: EOS C80 Firmware Version 1.0.1.1

Firmware Version 1.0.1.1 incorporates the following enhancements:

Adds support for Frame.io Camera to Cloud.
Available in regions served by Frame.io.
Enables the display of the digital tele-converter icon on [Main Recording Displays] of [DISP Level 2].
Adds the ability to apply Full-Screen display to an external display according to OSD Output setting when using [Peripheral Border Display].
Adds [1920x1080P] to [SDI Output Signal] option
Adds [CAMERA⇔MEDIA] to assignable button menus [CAMERA] and [REMOTE A].
Fixes minor issues.

Unfortunately I can't test that scenario, as my only SDI sink is a 3G monitor. Both recording and playback show up on that monitor, as HD signals.

But I suspect you may be right -- on the C80, playback is not the same as normal viewing mode. For example, if you shoot Log, ViewAssist doesn't work in preview or playback modes, on any of the outputs -- LCD, SDI, or HDMI.

Sorry, I can't help with a fix. I'm hoping firmware updates will improve the playback modes.

Thank you Rick. Unfortunately the FW update did not help. I guess this is just how the C80 works.

Thank you. Agreed, seems this is just how the C80 works. I will send an email to Canon to ask/request if UHD playback support is possible via future FW update.

Greetings,

You can do that on the Canon USA homepage. Look in the upper right hand corner, select [+]Feedback, then product.
