At 1920x1080 resolution (in crop mode) and 20 FPS with a fast card (I use a Sandisk Extreme Pro UDMA 7 160 MB/s ) the MLV recording is continuous ... until camera gets too hot and shuts down. And  the 50D overheats very easily, specially if you try to use a high FPS value. Keeping it at 20 FPS don't expect recordings much longer than 5 minutes. And you will need to let the camera rest some minutes betweeen shots to cool down.

20fps is going to be choppy. 24fps max resolution?

At 24fps I get 1600x900 continuous recording in crop mode, or 1568x882 in full sensor mode, both with a 16:9 aspect ratio.

Use this calculator to see what the 50D is capable of: http://rbrune.github.io/mlraw/

thanks. that helped a lot. so according to the calculator i can do 1984 x 844  2.35:1 in crop mode writing at 67.1MB/s.
And if i wanted non crop max rez is 1568 x 668 2.35:1 at 24fps? Can you please confirm those? so 1 x 1 sampling is always crop mode?

For a 2.35:1 aspect ratio, the nearest resolution value that you can actually set in ML menu for the 50D in crop mode is 1920x844.

I can record continuosly at this resolution and 24fps. I get more than 8 minutes of recording (this is a full 32GB card, I have no bigger CF cards) with no shutdown due to overheating.

For non-crop mode, yes, maximum resolution for 2.35:1 is 1568x668. With this setting, you can record continuously even at 30fps.

thanks. which brand card are you using 1000x CF to do 1920 x 844 ?

I've been on the 50D for some time and on the earlier builds, thus can give you some insight as to the resolution capabilities.

The 50D 'can' do up to 2000 in the horizontal resolution in raw recording, BUT only in crop mode and on an older build of ML. I remember using it last on a Tragic Lantern build. This build did record fine at 2000 across, but made the 50D heat up just idling for whatever reason, the newer build's do no heat up the camera anymore, so glad for that, but the crop mode resolution has dropped a little, so not 2000 anymore, but 1982 or something similar if I remember correctly.

Lastly, not in crop mode, it does 1568 pixels across in the horizontal resolution with aliasing and such. Hope that helped

@oc_masta Do you remember which build you used ?
I want to try it with battery grip and the heatsink pad mod.
I can currently get 100 sec on 1080p at 23.976 and 50 sec at 25p in crop.
I was able to get 1568 in 3:2 mode native sensor - pretty much continously. Same Sandisk card.

However I get random black and corrupted frames. Latest nightly build..

Do you still record without black or pink corrupted frames ?
