Thank you Levas! Will test this new build tomorrow.
1216 x 2052 at 25 fps is good enough for me

. It has a nice 1.5 crop. Just wonder, why isn't 25fps possible with 1640 x 2144?
I film band performances a lot indoors in dark, club like environment. 1216 x 2052 at 25 fps gives me continuous at 14 bit even.
I'm sure even 1640 x 2144 would be continuous with 1264 x 2144 16:9 and 25fps for me. 12bit is very useful outdoors or in bright indoors situations.
I was thinking a couple of day ago - we are SO CLOSE to the sweet 1280x2160, which could give as exactly x2 resolution vertically and 2/3 resolution horizontally, comparing to 1080p.
Levas' original 1:3 preset (1088 x 1842 )was in x1 zoom mode. Later, when he went to higher res, had had to switch to x5 zoom, don't remember why - he mentioned this a few pages back. They still work in x1 zoom mode, just exposure is off, doesn't work properly.
[edit]
Just tested the latest build from Levas, here's what I found:
- 2880x1200 25fps seem to work properly, tested 14/12bit. didn't find anything wrong with it. Couldn't get ML preview though for framing, only Canon LV, which is way off.
1216x2052 1x3 25fps and 1640x2144 1x3 24fps both work properly with ML preview, tried diff bitrates 14/12/10 - no problem there. The only weird glitch I found with both these anamorphic presets is that after about 30-40 sec you get this pink 'fog' that starts at the top of the frame and quickly fills almost the whole frame down to the bottom, making the picture pinkish. You can easily see it in ML preview - just leave the camera for 30 sec and watch the screen. When the screen gets pink, going to ML or Canon menu resets it to normal until it happens again.
Will test 2480x1396 25fps preset a bit later.
