Gary, I don't know if we're talking crossed-purposes here but I have used Magic Lantern scores of times specifically for my two 5D Mark II's to record until either the card runs out or the battery runs flat. I've used it lots of times with the 5D-II but its not available yet for the 5D-IV.Īlternatively you can control your camera for video (and stills) using your Android smartphone using DSLR Controller. Its been available for years and is reliable. You can completely overcome the 29:50 limit by installing the third party firmware called Magic Lantern. I've used that extensively.Ĭheck your card - it may be slower than recommended. Some point when no-one is doing or saying anything important and you can therefore "lose" 2 seconds.ģ2gb actually lasts for just over an hour as does a decent battery. To overcome this and if you have one camera rather than two (which you could edit to overlap) its best to physically stop and restart the cam at points in the proceedings at which that doesn't matter. You should see the amount of time being used show up in the screen. With the Mark IV it is shorter than that but it still happens. If you bring these into your editor you should be able to see the duration of each one.Īlthough the camera stops and restarts within 29:59 there is a short pause of - not sure with the 5D-III - around 2 seconds.
Your files of 3.96gb and 1.44gb will have corresponded with the total time of 29:59.
Each 4gb can be around 14 minutes depending on the content. Part way through the 29:59 it will finish one 4gb and start the next. Within that limit the file also has to be split into elements of approximately 4gb. It then stops and you have to push the button to start it again. Overall each time you start recording the camera can save for up to 29 minutes 59 seconds. There are two limits on the file size \ duration. I've used the 5D-II and the 5D-IV a lot so its easy for me :- ) I am aware of the maximum record time limit of approx 30 minutes, but so far I have never been able to get the camera to record for that long. I did not notice the recording light go off, and I missed recording about 15 minutes of the meeting.Ĭan anyone explain how this camera does it's recording, and how long can I record when using a 32GB - 40MB/s SanDisk card? The camera apparently stopped recording at the 1.44 size of the second file. One was 3.96 GB and the other was 1.44 GB in size. It appeared to continue to record, however when I got back home, there were two files on my card. Today I did a shoot of a teachers meeting at a local school.Įverything started out fine, then a few minutes into the shoot I got a message on the screen that indicated something about 4gig, and the fact the camera had to cut the video. I am completely new to video and I am using my 5 D III, and running into problems.
