1 - Don't kill global draw as it surely kills framing mode of course.
2 - Did you not manage to use the custom modes yet at all?
Follow this:
1 - select a CM mode. RESTART camera.
2 - modify your CM mode.
Done. It's already stored. You can move to a new CM mode redo step 1 and 2.
If any complaints against this please reread a1ex original post and provided links in this thread.
1. Yes, reactivating Global draw solved the issue for that particular 5k setting. I thought, it should be killed for all modes. It is a little confusing in your instructions. Please add a comment that Global draw should be killed only when using the fast modes. A hint reminding the user to kill Global draw when selecting the fast modes, similar to the Sound deactivation hint at 4k crop mode would be very helpful too.
2. No, I use my custom modes all the time and find them extremely useful! The problem I have is that switching from one mode to another does not work so smoothly here. Once I have programmed my settings and stored them under a CM setting, I don't want to modify them at all, as you suggest in your #2. I would like mode switching to work just on selecting it and restarting the camera. In fact, what happens is that if I am in CM1, containing the settings from my previous post (5k anamorphic, 14fps) and want to switch to CM2 containing my fast fps preset (1080p@43fps), when selecting CM2 and turning camera off and on again, it only partially loads the settings stored under CM2. Usually, camera stays in 5k anamorphic but at a much lower resolution. What I need to do is manually changing to the fast 1080p mode and then go to the submenu to manually change the resolution. What I noticed is that I need to wait at least for 5 seconds between turning camera off and on. Sometimes this works but most of the time I need to make these additional manual adjustments when switching from one custom mode to the other. And yes, I read A1ex's thread several times. I don't seem to be doing anything wrong.
Suggestion:
-------------
Is it possible to store custom settings CM1 - 5 in the Config menu in such manner that once stored, they should stay as they are and should be be editable only from the ML menus (ISO, aperture, resolution, frame rate, etc.) while working, just as it is now? However, once the user decides to switch from one mode to the other, the original settings of the first mode should stay as stored initially in the Config menu. This is how they have done it in the 5DMkIII. If that is possible on the EOS-M too, this will avoid a lot of confusion.
One more thought about fps override:
------------------------------------------
Considering EOS-M's speed limitations, fps override is the only way to get some filming jobs done (time lapses, high-resolution takes, etc.). Personally, I use it all the time and think that it is one of the most useful ML functions. I know that once fps override is changed, this may cause stability problems but on the other hand, if users cannot take advantage of it, this will be a serious functionality limitation. Right now, in the latest version of the May 9-th build, fps override works quite well and is pretty stable. I get 14 fps working at 5k full sensor readout and the fast modes at 1736x976 working with 43 fps correctly with no corrupt frames at all. Zeek reported stable 48 fps operation at 1080p and 2,35:1 and 2,39:1 aspect ratios. It would be great if these and other fps settings that do not exceed the camera speed limits stay as stable as they are right now.
Thanks.
