There was a vital feature back in the days in pravdomil's and a.d.'s builds — the cropmarks while recording with Global Draw off.
It is vital for low-end cameras, because of GD needs some processing power, and switching it off while recording gives several seconds of recording until skipping frame. But it is difficult to record without proper framing. Yeah, you can just stick some tape on the LCD but... you know, we are the serious guys right? ))

Here's what i'm talkling about:

This is how it looks while recording. I remeber, i built it in july 2013 with some additional changes and used to use it until nowdays.

I have no idea, why this wasn't included in unified, but I'd like to implement this nice feature at least in my builds, because it is the only reason which not allows me to call the nightlys "production-ready".

The problem is I can't find the source for that particular changes.

This thread is where I found this feature back in a day. It states from the beginning "mlv_rec: crop marks for GLDraw Off". It leads to the pravdomil's source:

https://bitbucket.org/pravdomil/magic-lantern-hack/
But here in the sources of raw_rec module I can't find any traces of that feature.

First link thread is closed and pravdomil says in last post: "Only two features are remaining (1880 width and  crop marks for GLDraw Off), but this is small changes so there no reason why keep this fork updated."

So what I'm asking for is: please help me to find the source code of this feature, or give me some clues on how to implement it by myself (i'm not so great at ML's structure yet, but have some basic coding skills)

UPD. Found the source here:
https://bitbucket.org/pravdomil/magic-lantern-hack/src/371d7565bcee926b4b3c50010a9fc15c41f7e0fc/modules/raw_rec/raw_rec.c?at=unified

These are the lines in raw_rec related to small hacks. In order to work them properly on 550D and 650D, we should know the timer addresses for those cameras:

Code Select Expand

/* change dialog refresh timer from 50ms to 8192ms */
        uint32_t dialog_refresh_timer_addr = /* in StartDialogRefreshTimer */
            cam_50d ? 0xffa84e00 :
            cam_5d2 ? 0xffaac640 :
            cam_5d3 ? 0xff4acda4 :
            cam_7d  ? 0xFF345788 :
            cam_700d ? 0xFF52B53C :
            /* ... */

Other way we get an error like
hackerror at 0
expected e3a00032, got 0

My question is, anybody knows these timer addresses yet for 550D and 650D?
Or may be devs can give us some clues to how to figure them out?

May I ask you please, what are these guys in DATA folder of ML, and what are they intended for?

APSC8P.LUT
APSC8R.LUT
FF8P.LUT
FF8R.LUT

It might be useful, if the 35mm equivalent crop factor display takes the actual crop factor of raw_rec crop box.
Let's say, I usually shoot at 1536xNNN on 650D, so my actual crop will be 1728/1536*1.6 = 1.8

In this case, if my lens at 28mm, the actual 35mm eq. will be 50, not 45.

How one can disable logging on startup? (...ML\LOGS\ROM0.BIN, ROM1.BIN)

Recieved the Mosaic Engineering VAF_TXi filter recently. Installed on my 550d, but when switching on or activating LV shutter pops and gives me an Err 20.
Anyone had the same problem with t2i?
