To enable crop mode just toggle the digital zoom button once - enter x5 zoom mode. Beware that framing on the LCD is a bit off what you get on the recording. 

Hello
I am shooting a music video in RAW with the 5D mark III and I was wondering about framerates.
I want to slightly slow time down with shooting at 30fps and then interpreting the footage as 23.976fps in After Effects. Is this a good idea, will it resolve in a smooth motion and does it in any way degrade the quality?
Also how much does this slow time down? I've heard it's about 20% but want to be sure in order to sync my audio track. If I speed up the audio by 20% and then slow down the footage from 30p to 23.976p and use the original audio track - will they match up?

As I mentioned earlier Andy's new build sort of fixed the problem. I can record at 1/64 at 30fps and at 1/54 at 23.988 fps.
The camera got pretty hot after 15 minutes of testing.

Read that. Not using auto ETTR. In C1 mode, witch is M in photo mode set to 1/50sec. ISO 100, auto WB. I first enable this mode, then LV, then Movie Mode, then Modules, then RAW, then I expose. EXP simulation is set to Movie, Exposure Override is not enabled. Should I always use it?
I'll try you 18Jul build in a moment.

Edit: Using Andy600's 18Jul build, it seems to be correct with exposure override. Its showing the ISO's as for example ISO100ov -  what does that mean? When I enable FPS override along with exposure override, I can get 1/54sec. and 1/49sec. with 23.976fps at ISO100ov set to optimize for low light. Also 1/64 at 30fps with FPS override off at ISO100ov, as well as other ISO values.
Shutter changes from 1/54 to 1/52 in 5x zoom with fps override on and from 1/64 to 1/59 with fps override off.
I should desable auto exposure on zoom mode (i guess).

My shutter is constantly changing to 1/33 when I gear up the ISO above 200. At ISO 100 I can get 1/48, but when I try to change the ISO things go south - the top LCD shows 1/50 but LV shows 1/33 and somthing like ISO 800eq when I'm on ISO 1600. Tried changing both with the wheel and in ML menu. THat is with Gregory's latest build, also with Tragic Lantern 2.0.

My shots tend to look underexposed compared to a still photo or h264 at the same settings. Anyone else with that feeling?
It still bugs me that LV and the LCD top display show different shutter speed values. Witch is the accurate one?

Hi, I`m new here. I`ve read a few entries here but I`m still not sure if the Eos 50D is able to record RAW video continuasly ( without dropframes ) at 1080x1920 - 24/25 fps with a 1000x CF Card UDMA 7 100MB/second write speed or even greater (I`ve seen one with a speed of 150MB/s).
Does somebody tested it this way ? What`s about heating issues at the sensor or the cpu? Is it possible to record a few minutes not croped HD RAW video ?
Do the 50D will have any other Codec options than RAW for video recording after the ML update ? Or is it maybe a better idea to buy something like a 600D which nativly is able to record vodeo including buttons...
But the problem is that I don`t want to have the hard H264 compression on the video. Does ML supports any other video codec solutions than cropped RAW for all these EOS which haven`t an CF Card slot? for example h264 with a much higher Mbit/s rate or even somethin like
4:2:2 DNxHD or ProRes ( if the copyrights allow those things )? 
Thanks for answering

and thanks for ML – I`m realy excited since I`ve found this homepage!!!

You can forget about codecs, at lest in the near future. With ML the 50D shoots 1080p at 30fps and 640x480 at 30fps, you can sort of change the fps with fps override.
For RAW, a 1000x cf card is a must, and you can shoot in full 1080p HD in cropped mode and in full sensor at 1584x1058 both in 24fps. The max write speed achieved at this time is 81MB/s.
If you want a canon camera for raw, you should buy nothing but the 5Dmk2/3 or the 50D.

mjstudio, it's a known issue. Raw recording is done while Live View is idle (at least on the canon firmware side). When it's not taking a picture or a video, IS is off to preserve battery life.
I guess they'll fix it in the future.

It generates a prores mov file, in order to preview your footage. It's only for reference. The raw frames are in the _dng folder.

So far its running real smooth, for 30fps Raw it's best to use aspect ratio 2:21 it runs with no problems.

I get the same stuff with shutter/ISO. When I put exposure override on it seems to be better, ISO says what is supposed to most of the time. But when I change it, shutter starts saying 1/33.3 and ISO 400ov. I guess it's supposed to do that, I just don't understand it. I'll reformat and try again.

Question: I'm trying to shoot 1584:674 raw at 30fps with Gregory's latest Jun28 build.
I don't understand the shutter values at all. Most of the time it says different things on the top screen from the ml settings in live view. The shutter sometimes locks at 1/33.3 or other values. The ISO shows 100eq or 200eq. When I change the ISO, shutter also changes. It all appears to be a bit random. I can get 1/59.7 with exposure override, but I don't think that is the correct way.
What am I doing wrong?
I use movie mode 1080p 30fps, 1584:674, no FPS override, small hacks ON, Global draw ON all modes and RAW histogram. Everything else is turned off.
And btw, does the Image Finetuning menu do anything in RAW?

Does the overheating effects the sensor after sometime?

That's why it's called overheating - heat beyond the safe levels.
What can be considered overheating for the 50D - I dont know. I don't let it go above 57 deg. Celsius.

Thought of that and just did it. Let's hope I don't forget again.

Can I have a moment to share a quick suggestion?
Since I get more frames when shooting in JPEG mode, rather than RAW mode (in Canon Menu), when I shoot video I change the mode. But then I want to take a picture, so I do. Only on the computer I realise that I forget to turn the mode to RAW again.
I know about the bad settings warning feature in ML, but when I use it it constantly blinks when I shoot raw video.

So is there a way to maybe make the camera switch to JPEG when RAW video is enabled, and then switch back to RAW? Or maybe desable the bad settings warning when RAW video is enabled?

Are your 50D's heating up? After 20 minutes of raw video shooting mine gets to about 50deg. C. It does the same for about an hour continuous h.264 shooting. I shot a concert for two hours straight last week and the camera was pretty hot. The reading showed 57deg.
Normally when I fire it up it shows about 35deg.
How hot should I let it go before I give it a break?

What kind of video card should around 100-200 usd would be enough to run resolve properly? 18-20 fps is enough for me.

Thanks.

I installed the latest June 13 build and it looks like it's speedy. But Auto-ETTR seems to have disappeared. I have the camera set to RAW in canon menus and I have loaded all modules. Is that normal?

a1ex, I have a 50D. Does what you say mean that I need to enable Movie mode in ML menu?

The 50d was designed to have video. Canon just dropped it out on the last minute, because it was smarter to introduce it on the 5d2. 50d even has a mic socket for where the holes of a mic would be if you open it up.
Although very unlikely the idea of a USB mic directly to the 50d sounds awesome.
USB condensers require too much power I think. No idea but I'm not sure the 50d USB port could power anything at all. So that leaves out most to the USB mics out there.

Not a raw question, but how would you shoot a music video with the 50D? I would love an easy way to record scratch audio.

Just another test video. Trying to wrap my head around the low light performance of this beast.
Shot with Sigma 30mm f/1.4 at 1/50 H1 (ISO 6400 equivalent) at 1592x864. Upsized in Premiere to 1080p (just scaled 121%).

Pushed the exposure in ACR two stops up, so equivalent = ISO 25.600. Added a bit of luma and color noise correction to taste, kept sharpening low.

Here's a screen grab, edited and unedited

Did you use FPS override or is this 30fps?

Don't know if it has been discussed yet, but my screen goes pink with the LV image overlaid below when I'm using 5x and 10x zoom. Returns back to normal when I disengage the zoom function. That is using the 28may build by gregoryofmanhattan.

I still need help over those cf cards. Komputerbay 128gb 1000x vs. 64gb 600x vs Kingston 32gb 1000x. What should I get?

I am about to buy a CF card tomorrow for my new 50D. Help me choose between Komputerbay 64gb1000x or 128gb600x. Are there any issues with running ML on a 128gb card? Is 600x enough? I think the 50D is UDMA6 compatible, so is there going to be any benefit from 1000x card?
