60D stops recording instantly

[tubecamera]

Playing around with my 60D over the weekend I had the camera abort the recording as soon as it was started several times. Using 16gb Transcend SDHC 10 cards. All cards were freshly formatted and had nothing on them but ML.

One card would not run hardly at all. The other card seemed to work fine but would abort now and then. Usually after the camera had been turned off so it was the first recording. After that it was usually OK.

If the camera records at 21Mbs and these cards are good for 30 there should be some margin there. Have used them with other HD video cameras with no issues.

I should also say I was outside with the camera. Temp was around 70F and sunny. Camera in the shade for the most part but had some sun now and then.

What are you folks using and do you have these aborts.

Any thoughts?

Thanks!

Build date?
RAW or H.264 recording?
Settings for recording?
Modules loaded?
Tested with global draw on/off?

[tubecamera]

Build date for the camera? How can I tell that? Firmware is V1.1.1 . Camera was a refirb from Canon's web site.

Using H.264 to record at full HD 30P and 24P w/ same result

Not sure what you mean by modules.

Global draw? Not sure how I had it set. Factory default most likely since I have no idea what this is.

Camera is at the house and I'm at work. Sorry I cannot tell you more than this : (

Delete ML\Settings\MAGIC.CFG and try again.
Results?

[tubecamera]

Appreciate the help but you are getting way ahead of me on this.

Do you want me to delete all ML files from the SD card and try shooting without these files?

If so, I can try a card with no ML files on it.   

[Walter Schulz]

Delete \ML\Settings\MAGIC.CFG

[tubecamera]

Got it!

Will report back tomorrow.

I put the SD card that was crashing almost every time on Saturday back in to the camera today. Still with same Magic.CFG file. It ran fine. Only one time did it stop recording. When pointed outside the buffering boxes on the right side appeared. First bottom box white. Stayed that way. Moving camera inside (where it was darker) the buffering boxes went away. Repeat camera location and it came back.

Today the temp is much lower than Saturday. Nice cool day.

Deleted the Magic.CFG file and redid test.

First recording outside the buffering boxes came on with two whites then it went away after about two seconds. Multiple records outside and the boxes did not re-appear at all. Ran one test for about 5gb no issues.


Conclusions?

[dmilligan]

The amount of detail/motion in a scene can have an effect on data rate, keep that in mind. I doubt this has anything to do with ML anyway. You can always boot without ML by holding SET when you turn the camera on.

[tubecamera]

What about the ambient temp having an affect?

[dmilligan]

very doubtful

[tubecamera]

OK.

Well, both indoor and outdoor tests were done static and moving. Even when static with no movement in the scene I had buffering boxes before deleting the CFG file as Walter suggested.

The only difference between today and Saturday was the heat factor.
Hence my question about ambient temp having some affect.

The only difference between today and Saturday was the heat factor.

I doubt it.

The amount of detail in the scene can have an effect too, that includes noise, which means different levels of light can have an effect on data rate as well, even if you're shooting the same scene and not moving the camera. You need to control all other variables to be able to prove it is the temperature. That means shoot the EXACT same scene with all the same settings, changing only the temperature (via a hair dryer or ice pack or something).

I don't really know why Walter told you to delete the ML settings, this likely didn't do anything. This problem very likely doesn't have anything to do with ML at all. You can prove that by using the SET button on startup like I said. Startup without ML, is the behavior the same as with ML? If so your problem is not ML related.

[Walter Schulz]

I don't really know why Walter told you to delete the ML settings

He clearly hasn't any clue what he has done, which settings he used, which settings he changed. Therefore: Wipe it all out, restore defaults and let him try to get a clue.

[tubecamera]

Thanks. When I get a clue I'll be back.
