Hello!
I've used my Canon 90D for streaming for years. Recently, my camera has been acting up, introducing a new error all of a sudden. The message reads "Press <> (start/stop button) to prepare for movie shooting". Before you read on, this isn't about the 30 minute default limitation, I've circumvented that years ago. I'm using a clean HDMI on the Manual (M) dial setting and with an external battery power supply. The camera has worked flawlessly for more than five years, streaming and utilized for video meetings on a regular basis. It's never faulted.
The odd thing, apart from the message appearing at all, is that the message pops up randomly, sometime after ten seconds, after three minutes and sometimes it takes 15 minutes or more. It also occurs more often with my 18-55 mm lens than my 24-105 one.
I've tried cleaning the contact nodes (sic) on my lens. I have turned the HDR setting to off (just out of trial and error). I have jiggled as well as pulled out and inserted the HDMI cable as well as the USB one going into the computer, trying to eliminate possible bad connection. I've taken out the external battery dummy and used the standard one - all to no avail. The only thing I haven't tried yet is a factory reset. I kind of figure that the last step, even if I'm just an amateur photographer with no intricate settings.
I've also read that there could possibly be overheating issues, but I've never seen any signs of that. The camera has never shut off or sent out any error codes before. I've used it on hot summer days with no issue, and this past month when it started actin up, it hasn't been that hot. I've also used it very little this past year as I've been unemployed for some eight months.
I just remembered that I have not tried taking out the memory card. Not that I know why that would make any difference, but it can't hurt to try.
I've found more people having the same problem. I've yet to find anyone with this issue appearing randomly, though. Most simply haven't eliminated the default 30 minute limit.
I interpret this message as if the camera either "thinks" it's not being used as purely viewing (which it is technically - it's not recording), or that it looses contact/connection to what it's currently doing and somehow goes into recording mode. The message itself is one normally associated with recording, after all.
Sometimes, the initial message mentioned above is also followed by a second one saying I should check that there is a lens attached to the camera and then press the <> button again.
I welcome ANY tips on this as I'm stumped. All of us know that equipment doesn't come cheap. I've been very content using a DLSR as a webcam - it's easier to get a high quality image, and I can fairly easily remove it and use it for taking photos. Getting a webcam offering me the same quality is not cheap, and getting a second DLSR is too expensive for what I'm using the camera for at the moment.
Thanks and have a nice day! 🙂
