I recently joined but I really enjoy this community so I would love to contribute and help out anyone I can. Yes, it is possible but be prepared to get your hands dirty leafing though pages of documentation. TL DR: No, you cannot EASILY control two DSLRs from one machine. *I brought this up to a few Canon reps at a conference and they all chuckled and agreed with me how bad it is, good people IMO your best bet would be to start there. I cannot express how much I love Gphoto, it's fast and well documented ( cough cough look Canon cough). MagicLantern - Custom Canon DSLR firmware (most models >1 year old, they just recently added the 70D to their list) (I automate my cameras with python scripts for timelapse and other projects.)
Gphoto2 (linux/mac) - Powerful program that allows you to type a single command to control nearly all functions of the camera. Automated Malware Analysis - Joe Sandbox Analysis Report. From what I gather, live view streams don't cause the cameras to overheat as much as recording.Īnd as far as software, check these utilities (both are open source). However, DSLR sensors weren't designed for extended video scenarios (sensors get too hot leading to poor image quality or thermal power cutoff). The simplest option I would recommend would be to capture the HDMI out on each camera and work with the video streams that way. However, If you have any questions at all I will give the best of my knowledge to help you. At this time I don't think I can release details of the setup (I'll have to check). I did manage to find a way to set up and control 3 DSLR cameras from a single host machine but the route I took is in no way the best nor the cleanest. Functions that you cannot easily call with available libraries in the SDK (to my knowledge, again the documentation barely glosses over any of this). Whatever Canon does to directly stream the image data from the sensor to the host is some hardware accelerated (Digic processor) function built into the camera's firmware. I digress, of all attempts I made, I still could not achieve decent results in fact the guy who worked on this before did it better with a live view stream with ~500-1000ms delay at around 10fps. The only way to be sure is to limit connectivity to one camera and assume any new stream comes from the same camera*. These streams at times will sever and reconnect rapidly and when this happens there is no way for the host to determine whether the new stream came from camera A or camera B. The one thing the documentation is very clear on is that these streams are not unique to one camera (not sure if (USB or EDSDK limitation).
SPARKOCAM BAD SOFTWARE
Canon cameras connect to the host computer running it's utility, when live view mode is triggered (remotely) some poorly documented software magic happens and the host & camera open a video stream giving you a very responsive remote live view. Now the long(ish) answer, this pertains mostly to Canon's EOS Digital Software Development Kit (EDSDK) as Nikon's is limited feature wise and confusing as hell to work with (personal opinion from 2 years ago, it could be better now). Sadly, the short answer is no, you cannot have two USB video streams on the same host machine (as per Canon EOS SDK documentation). So I guess if it happens that the sensor overheats I will know about it.Interestingly enough, I spent a solid year of my masters degree (almost done) trying to accomplish this goal. Press the OK button and try using Live View again when the camera has cooled down. Disabling Live View temporarily to protect circuitryĭescription: Live View cannot be used because the camera's internal temperature is too high.
I figure that after messing around with different combinations of lenses on the camera I should be able to rig up something that will work nicely assuming the video quality is half decent to start with.Īs far as overheating goes, I found this in the troubleshooting section of the manual:Įrror message: Camera overheated. 25-200x is what they seem to have and in order to work for my purposes I need to have the coin at least six inches from the camera in order to use tools, which could be a problem with one of these standard microscopes as it seems that many of them only focus well if you are almost on top of the item you are focusing on. I need 5 - 15x magnification and even the usb microscopes you can buy usually don't go that low. What I am planning to use it for is cleaning ancient coins. IMHO useful for a photo-booth or model feedback but not good enough for macro and other critical modes.Awesome. Yes, and to connect to a computer use a 'video capture device'īetween the AV cable and the computers usb input.Īll actuations still need to be made using the cameras controls but the live screen of the camera is transfered to the computers screen (not HD)
