It's been a while since I tried Magic Lantern the last time. But today I tried it again with my 50D in RAW and MLV and was amazed how fast and easy the conversion
was with raw2cdng on Windows 7.

I also read about the crop_rec_4k with the 5D Mark III. I don't have this camera yet but think about buying a used one if I can find a good deal.
Would the raw2cdng application work also with 12 or 14-bit lossless compressed MLV files?

Hi,

do you think it might be possible to include resolution settings for anamorphic? I already experimented with the EOS 50D and anamorphic but it is limited to lower resolutions. With the 5D3 it might be possible to go higher and according to the first crop_rec on steroids posts it's not unrealistic that it might work at continous recording.

 /*   24p   25p   30p   50p   60p */
    [CROP_PRESET_3X_TALL]       = { 1920, 1728, 1536,  960,  800 }, /* 1920 */
    [CROP_PRESET_3x3_1X]        = { 1290, 1290, 1290,  960,  800 }, /* 1920 */
    [CROP_PRESET_3x3_1X_48p]    = { 1290, 1290, 1290, 1080, 1080 }, /* 1920; 1080p45/48 <- 50/60p in menu */
    [CROP_PRESET_3K]            = { 1920, 1728, 1504,  760,  680 }, /* 3072 */
    [CROP_PRESET_UHD]           = { 1536, 1472, 1120,  640,  540 }, /* 3840 */
    [CROP_PRESET_4K_HFPS]       = { 2560, 2560, 2500, 1440, 1200 }, /* 4096 half-FPS */
    [CROP_PRESET_FULLRES_LV]    = { 3870, 3870, 3870, 3870, 3870 }, /* 5796 */

The aspect ratio does not necessarily have to be 4:3. The new Arri Alexa models allow for a new 6:5 ratio. With 2x anamorphics that leads to 2.4 : 1 and is perfect for anamorphic shooters. http://www.arri.com/de/camera/alexa/kameras/kamera_details/alexa-sxt-plus/subsection/new_sxt_features/

A ML resolution of 2048 horizontal and 1716 vertical would be the best option. With 2x anamorphics that would be 4096 : 1716 after desqueeze just like the new Alexa SXT 6:5 ProRes 4K cine anamorphic mode :). If you have the time it would be great if you could add some other resolution options in that area in order to find what works at continous recording. 1920 horizontal and 1600 vertical would also be great for 3840 : 1600 desqueezed.
