Nightly builds with Raw recording supporthttp://www.magiclantern.fm/forum/index.php?topic=6362.0
1. Make sure you have CF card selected.
2. Switch your camera to video mode (flip the video lever), focus your subject and adjust for the scene . Works in M, AV, TV modes.
3. Select the 60 fps video specification from Canon Menu by pressing Q button.
4. Use the Joy stick to move and make "blue" the video mode.
5. Scroll through the videos to 1280 60fps.
6. Press half shutter to return to Live View. If you have not loaded the raw_rec module then:
7. Press trash button and go to Modules Tab using your joystick or scroll wheel. (It is an icon with four little squares)
8. Use the scroll wheel or joystick to highlight the raw_rec module and then press the set button to enable it.
9. Reboot the camera, then press trash button and if the module loaded correctly you will see it in bright white with a green dot on the left.
10. Scroll to Movie Tab with the small scroll wheel or joystick and then scroll to Raw video
with the large scroll wheel or joystick. The Raw Video should be OFF.
11. Enable RAW video by pressing the Set Button. Look at the video settings and also look near the bottom of the screen for information about CF speed requirements to meet current fps and frame size.
12. Press Q and Set to chose the appropriate Resolution, or use the little scroll wheel to scroll from available options. If your card is not fast enough then select acceptable resolutions. Remember to look at the bottom of the screen to see how resolution affect card speed requirements.
13. Scroll to Aspect ratio 16:9 is the default. You can scroll with the little wheel or press Set to change it. By changing the aspect ratio the camera chooses an appropriate video height. Some heights are not the most common ones but these combinations offer better writing speeds. You may have to crop your video in post.14. (AUDIO NOT AVAILABLE RIGHT NOW, USE EXTERNAL RECORDER-->)
If you want to record audio (wav file to SD card) scroll to Sound and select Separate WAV, or sync beep, or OFF
14. Preview: Auto
. Press Set
to change it to: Canon, ML Grayscale
(see note 6)
15. Digital dolly: OFF
On to allow the recording area to scroll from left-to-right or up-down during cropped video or when recording at smaller resolutions then max (1920x1080) Use the Joystick to control the direction of the scroll.
16. Frame skipping: OFF
To continue recording even if skips frames then scroll to and select Allow
17. Card warm-up: OFF
Press set to select a warm-up file size when camera boots. Some speed improvements obtained.
18. Memory hack: OFF
. Press Set to on This frees up more memory to get extra frames in the buffer.
19. Small hacks: OFF
to improve the use of memory to increase recording buffer.
After recording a RAW file you can preview it by coming back to this menu and scroll to Playback selection and pressing Set
21. Press Q
and then move to Overlay
and set Global Draw
. See note 7.
22. To get back to LV just press trash button or half shutter.
22. To start and stop recording press the LV button
Option for 50 fps recording:
23. Move to the Movie tab and select FPS override with the scroll wheel. (see note below)
24. Press the Q button
25. Change the Desired FPS to 50 using the small (top) scroll wheel.
26. Move to the Optimize for with the large scroll wheel.
27. Change to Exact FPS with the small scroll wheel.
28. Press the Q button and then press the Set button (on the center of the large scroll wheel) to enable FPS override
29. Now FPS should read 50.
Note 6. Canon
preview is standard full color, ML Grayscale
is in B&W and also shows the video in its final cropped view (used for framing), Hacked
is special fast hack to increase card writing speed at the expense of freezing Live View.
Note 7. If you set Global Draw OFF you will loose histogram, zebras, etc. But you will gain speed. In some cases Global ON is more likely to get pink frames since CPU is working very hard, and also consumes much more power.
Make sure that in Canon Menu:
Image Quality = Raw
Auto Lighting Optimizer = OFF
Long exp. noise reduction = OFF
High ISO spee NR = OFF
Higthlight tone priority = OFF
Multiple Exposure = Disable
HDR Mode = Disagle HDR
----------------------Other technical aspects:
The frames recorded at 60 fps are squashed and need to be corrected in post. This is a Canon sensor property that cannot be changed. Probably to sample the sensor at 60 fps it can only be done skipping some lines therefore the image is squashed, not at full resolution, and with aliasing.
The height stretch factor is approximately = 1.67
That means 1440x480 should be stretched to 1440x790 to look correct.
On a 1000X 32gb Lexar can get:
1440x480 at 60 fps --> When stretch it becomes 1440x803 very close to 16:9
1600x540 at 50 fps (using FPS Override) --> stretced to 1140x903

Since the quality of RAW is so good, maybe these videos could upres to ???x???. I have not tested this yet!
Here you can see some frame grabs from standard RAW video compared with 60 fps (stretched) and Canons 60 fps.
The RAW version is an improvement over Canons but not as good as standard RAW.
So the stretching does some damage!!! I dont know if it is possible to get 60fps non squashed video!!
OTHER HELPFUL LINKS:
To help the DEVS and everybody it would be a good idea if specific RAW video issues are discussed in a separate thread based on the camera under discussion.
