I did some more tests, this time with HDMI plugged in. I got strange pink frames every so often.



Recorded at 1592x896 at 25fps

Same settings with HDMI unplugged and it was fine.

Just been doing some testing at 1592x896 and 25fps

I can get constant recording with the following settings:

Global draw on
Focus peaking on
Sound mode off
Hacked mode on
ISO 500

If I raise the ISO any further then it skips frames.

1. I see all these amazing test videos with 24 FPS. Is there 25FPS? For my work it is crucial.

2. I read the other day about the problem with electronic aperture for EF lens. I would appreciate if someone assures me that I can control my electronic aperture while shooting RAW video.


I've just shot some footage at 25fps and it recorded fine, I'm using a 1000x card, the buffer usage looked pretty similar to 24fps.

I also tried out an EFS lens (Tamron 17-50mm) and found that when I stopped it down the LV image didn't darken much. Even when I stopped down to almost closed, the LV image was still pretty bright.

Manual aperture lenses seem to work fine though.

Have you tried exposure override in ML's exposure menu?

EDIT: override not lock, sorry.


Thanks for that, I've turned it on and now the ISO dial is having an effect. Do you have exposure sim on or off?

What settings are you guys using in liveview? I have a manual lens on the camera and when i change aperture it changes brightness in liveview as it should.

I must have the wrong setting somewhere because when I increase the ISO it has no effect and the spot meter doesn't move. Even if I put it on ISO auto nothing changes.

I checked the ISO and it's working fine through the viewfinder, just not in liveview.

Any ideas what I've got wrong?

Which card are you using?

Just been out and filmed something in the garden, going to see how it turned out! Strangely I've got a .R00 file in with the RAW's

Link should work now.

Yeah I'm using the build you mentioned.

I just did another test with everything switched off and it now runs continuously at 1592x896. I wonder how Julian is getting continuous with global draw on??

Here's a quick screengrab:

Finally got my card and just did a quick test:

1320x742 - continuous
1440x810 - 800 frames
1592x896 - 200 frames

All 24 fps

Komputerbay 64gb 1000x

I'm getting slower than other people so I may have something still turned on in the canon menus. Do you guys turn off histogram/wave form etc?

This is with global draw set to liveview

Also when you run the benchmark how do you get a screen print?

@JulianH

Good call on sending the 50D to 1%. Hopefully my card will turn up today and I can help with testing.

I'll PM you for donation details.

Thanks for everyone's hard work so far.

Hi, my 50d turned up yesterday, still waiting for my komputerbay 1000x 64gb though. As soon as it turns up I'll help out with the testing.

Looking forward to shooting some raw, I've had enough of 8 bit video!
