EOS Bodies - For Video / Re: Problems with Canon mk3 locking up
« on: September 11, 2012, 11:49:47 AM »
Sorry to hear about your lockup issue, but very glad that you have made a post about it here.

I just ran a test on my 5D3 and had no problems going through the whole 29 minutes 59 seconds cycle before I got a message that video recording was auto cancelled.

I recorded in ALL-I, 1920x1080p, 24 fps, manual mode 1/50, f/4, ISO5000. Recorded to CF card type Sandisk Extreme 16gb, 60mb/s. I don't have any 32gb card to use for testing.

Camera was stationary the whole time on my desk pointed towards my NAS, so the only movement in the image was a small blinking LED.

I will try another test later with movement in the picture to see if it makes any difference.

Long time reader, first time poster here. Might aswell try to make it something constructive and hopefully helpful.

My tip: AE lock & Hold

I normally shoot in manual mode, but sometimes it happends that I wander into the lands of Av.

My problem with Av (and any other auto-exposure functions) is that whenever there is a big variation in the amount of light on your subject and on the surrounding scene and background, it tends to either get overexposed or underexposed. Now I can always go in and use exposure compensation, and I will in most cases do that before I even take the first shot judging by the scene. Sometimes I'll go bingo and other times I'll take another shot.

With the 5D Mark III came a rather interesting feature - AE lock and Hold.

Like the normal AE lock function it will lock your exposure, Very handy to use with spot metering in the situation I described above. But unlike it, there is no auto cancel after a set period of time or after the shot is taken. It will simply lock your exposure untill you press the button again and unlock it. Fancy, eh?

The function can be set in the custom controls panel.
