Experiments

The following builds are works in progress, known to have rough edges.
Please test thoroughly before considering them for serious work.
The functionality from this page will be integrated in the main builds as soon as all major issues will be ironed out.
However, we need your help. If you use any of these builds, please report your experience.
Still confused? Each experimental build has a link to the relevant forum thread, where you can discuss the new features.
You may also check this page for ideas on how to help, and this page for how to suggest changes with a pull request, from your web browser.

Latest Lua updates + fixes (please review)

Latest Lua updates (details).

Includes many other backend changes, e.g. focus, menu, Q button handling, fonts etc.

Therefore, it's important to give it a good try on all functions, not just Lua, so we can include it in the nightly builds.

Also includes lens.focus_pos and dynamic-my-menu.

f7947b6: raw_diag: fix BUSY screen with 2-shot analyses in still photo mode
https://www.magiclantern.fm/forum/index.php?topic=10111.msg223667#msg223667
Issue: latest memory backend prefers SRM for very large buffers, but these can't be kept allocated during a still image capture. We need to use shoot_malloc instead.
TODO: tmp_malloc and related functions should be renamed in the memory backend, for consistency.
Thanks @timbytheriver for reporting.

Build Log

4K raw video recording; lossless compression

crop_rec module with higher resolutions (4K, 1080p48 etc):

5D3:

  • 1920x960 @ 50p (both 1:1 crop and full-frame - 3x3 pixel binning)
  • 1920x800 @ 60p (same as above)
  • 1920x1080 @ 45p and 48p (3x3 binning)
  • 1920x1920 @ 24p (1:1 square crop)
  • 3072x1920 @ 24p (1:1 crop)
  • 3840x1600 @ 24p (1:1 crop)
  • 4096x2560 @ 12.5p (1:1 crop)
  • 4096x1440 @ 25p (1:1 crop)
  • Full-resolution LiveView: 5796x3870 at 7.4 fps (128ms rolling shutter).
  • Continuous: 3072x1308 @ 24p, 1920x1080 @ 45p, 1920x960 @ 50p, 1920x800 @ 60p, 4096x2560 @ 8p, 5796x3870 @ 5p.

EOSM, 650D, 700D, 100D:

  • 1736x696 @ 50/60p with 3x3 pixel binning (actually column binning / line skipping)
  • Lossless compression: 1736x976 @ 24p continuous (this is the maximum 16:9 resolution with 3x3 sampling)

6D:

  • 1824x634 @ 50/60p with 3x3 pixel binning (actually column binning / line skipping)
  • Lossless compression: 1824x1026 @ 24p [continuous?] (this is the maximum 16:9 resolution with 3x3 sampling)

Notes:

  • It's quite bleeding edge (expect bugs)
  • Includes lossless compression for MLV (mlv_lite/mlv_play) and DNG (silent/pic_view)
  • Includes lua_fix and dynamic-my-menu
  • You will generally need to use the (non-realtime) preview from the raw recording module.
  • Setting the preview to Frozen LV will give sligthly better recording times.
  • Modes with higher vertical resolution will have real-time preview only for the top of the frame.
  • Modes with higher horizontal resolution will have the preview completely broken.
  • Centered x5 zoom will show either a cropped real-time preview, or a slow preview with correct framing (half-shutter to toggle).
  • mlv_lite has lossless compression, H.264 proxy and experimental sound recording via mlv_snd
  • mlv_rec works too, but without lossless compression

This is also the "de facto" bleeding edge branch, with other experimental stuff being tested here.
