Rebel T5- Does magic lantern help fix the terrible autofocus of the official firmware? Also, I noticed the audio is silenced during video? Is that an option that can be turned back on so the audio can be recorded?

Got a very easy coding task (trial and error, but the issue is likely hardware-specific, so it can only be solved with the camera in one's hands):

https://bitbucket.org/hudson/magic-lantern/issues/2821/green-display

It works fine in QEMU, so I'm unable to fix this error myself; please find some things to try on the issue tracker.

@Mr_Propane: all the audio options on this camera are in Canon menu.

Hi, I'm new here and have a question for testers/users of ML on 1200d. Did anyone manage to record  longer than 12min videos by lowering H.264 bitrate below 1.0 under movie settings?

I consider buying this camera and I need to shoot continuous videos with 1920x1080/30p for at least 20 minutes.

Thanks a lot!

I bought one of these secondhand today for £100 for shooting B-roll in some silly little video projects me and my buddies are doing.

I've installed ML successfully, benchmarks show this as capping out at 21MB/s, my temp 16GB Sandisk Ultra card doesn't write fast enough to saturate that but I assume with the 21MB/s read speed cap that this camera can't exceed 20MB/s write speed? Therefore it is suited for sub-720p ML Raw.

Has anyone had any experiences contrary to my assumption above?

Hmm, about issue with black screen after silent full-res pictures with review off:

I was able to fix it by appending ResumeLiveView(); under cleanup section of `silent_pic_take_fullres`

Code: [Select]
gui_uilock(UILOCK_NONE);
ResumeLiveView();  // here
return ok;

Probably this is not corret, and the general idea was to do some other things to return back to live view, also it may brake something, but it should be enough to work on hyperlapses - after returning to liveview we can use cropmarks to hold somepoint. Thats great.
If someone need binary firmware with a fix here it is - https://maketips.net/tip/495/magic-lantern-for-1200d-with-silent-no-black-screen (I hope this is not rules violation or something like this). Here is also detailed steps how I built that thing if someone wants to repeat https://maketips.net/tip/420/build-magic-lantern-firmware

Hi,
I am able to set CBR under values less then 1 (e.g. 0.5) and record something, but I can't find 1920x1080/30p. Do you mean 30 fps? If yes then there I have only 1920x25, 1920x24, 1280x50, 640x25 modes. I am not working with video staff here but can test something if needed. Probably 30p can be achieved by some haks in ML.

This can be achieved by setting your region settings in the canon MENU to NTSC instead of PAL.

Ok, Then looks like I was able to record 1920x30 .MOV 20-minute video with 0.5 CBR (took 3.7 Gb).

While reviewing the 1300D code, I've noticed a few things that may need double-checking on 1200D, in internals.h:

- Display filters are likely to work out of the box:
Code: [Select]
#define CONFIG_CAN_REDIRECT_DISPLAY_BUFFER_EASILY
#define CONFIG_CAN_REDIRECT_DISPLAY_BUFFER
#define CONFIG_DISPLAY_FILTERS

(this will enable fisheye correction, anamorphic preview, raw video preview with correct framing and a few others)

- CONFIG_EXPSIM: I expect this to work (in LiveView, this should disable exposure simulation, so the brightness you see on the screen will no longer match the dialed exposure)

- CONFIG_FPS_AGGRESSIVE_UPDATE: not sure if needed. With FPS override turned off, open the submenu and write down the timer values in all video modes (including photo mode and x5 zoom). The same test was done for 1100D.

- CONFIG_MOVIE_AE_WARNING: there are manual video controls, but they are disabled by default; this should probably be enabled.

If any of you can compile from source, can you try to switch the above options and report back?
