In the filemanager module It will be useful to add a feature for create new directory in which put all pictures by subject or by date.
It needs also a keyboard to write the name of directory or comment on the pictures or video.
I found very useful the feature of MLV that now can create automatically a new directory for each new video.

Dear all,

I'm very grateful to the magic lantern developers  :)

It reveals a new way to take planetary video.
Nowadays a dedicated 12 bit video camera for planetary astronomy could be quite expensive and required a computer with fast usb2 or usb3.

A huge step up compared to 8 bit compressed video from camera (640x480 60 fps 550D, 60D) or using PC software to grab live view in 5x (crop) mode.

After loaded magic lantern nightly build and activated the 14 bit raw module on my 500D I'm able to record in 5x zoom mode lots of different size frame at true 1:1 pixel resolution, the only one useful for planetary video.

I have a 32 Gb SD SanDisk Extreme 45 Mb/s (do not use Sony SDHC UHS-I 94 Mb/s, it's slow!)

The 1:1 pixel 14 bit raw frame I got (I compare them with CR2 frames) was:

Continuous video (max 4 Gb) - However in planetary astronomy is not important to record continuous video, 1000 to 2000 frames is enough.

640x480        22 fps   OK
704x470        22 fps   OK
960x480        22 fps   OK
1280x480       18 fps   OK
1344x504       17 fps    OK  (1000 frames =1.1 Gb)
------------------------------------------------------------------
1152x490       22 fps OK but just 1100 frames (19.1 Mb/s)
1344x504    22 fps OK but just 300 frames

In 5x mode (1:1 pixel) the VERTICAL limit seems 510 pixels (is it an hardware limit?).
If I try to set a vertical resolution > 510 the frames was corrupted.

I'M INTERESTED TO KNOW ABOUT OTHERS CAMERA PERFORMANCE IN 5X MODE

Can them get larger size frames or faster fps?
