    Again, the pink dots in the highlights of your video appear to be very different from the pink focus pixels that are discussed (and mapped out) on the ML forum.

     

    Upon a closer look, I see that focus pixels sometime appear in your video in the same frames as the pink highlight "fixed pattern" dots.

     

    Here is what pink focus pixel dots look like:

    Notice the distinctive, orderly pattern of the pink focus pixels.  These faint orderly dots are easy to map out.

     

    The pink highlight dots in your video seem to be some other problem, likely related to the pink highlights phenomenon (completely different from the pink focus pixel phenomenon) and possibly also related to fixed pattern noise.

     

    Again, you additionally  have a "black hole Sun" problem.

     

    I think that the free, open source MLV App will solve most of your problems, but I am not familiar with it.

    yeah, after a couple more hours reading through last night, I downloaded the MLVFS program and used some options within that to take care of the issue, which worked beautifully! It even took care of the black hole sun. : )

    Those pink dots don't look like the typical focus pixel dots.  The problems is something else.  It appears that you are also experiencing black (pink?) hole Sun effect.

     

    I seem to recall reading in the Magiclantern EOSM thread and watching one or two recent @ZEEK videos on how to remedy pink highlights and black hole Sun with EOSM raw.  As I recall, one just lowers the white level in MLV App to eliminate the pink highlights.

     

    Perhaps, @ZEEK and/or @Alpicat will chime in with suggestions.

     

     

     

     

    Thank you so much for the feedback!


  3. So I finally got my 6mm Pentax Cosmicar 1.2 C-Mount Lens in and decided to take it for a spin today.

    It was a game changer!!!

    While I was waiting for that lens to come in I was using a Canon 28-135mm f/3.5-5.6 on an EF-M converter and it was always too bright to use during the day even at f/16 and the 5x crop was horrendous, but as I hoped, everything changed and became clear and made sense once I got the Pentax 6mm.

    I used the same settings as @Matt James Smith ? (thanks for the specs by the way Matt!):

    6mm f/1.2 Pentax TV lens (have not yet added a shim for infinity focus)
    EOSM with latest ML build
    18fps override (exact)
    5x zoom
    4:3 aspect
    1440 x 1072

    I LOVE THE LOOK SOOOOO MUCH!! THE ONLY ISSUE ON THIS FIRST RUN WAS THOSE DAMNED PINK DOTS!!! I know they have been discussed on other threads, so it's time to dive deep into that issue, but for now I couldn't be happier!

    Only effects are some slight dust and movement via FCPX's "Aged Film". Other than that, it's straight out of camera. Also per Matt's deduction, I have slowed all clips down to 72% duration on a 24FPS timeline in FCPX.

    Here is a little vid I put together quickly from the shots I took in the Santa Barbara Harbor this morning.

     

     

    So far I'm only in for $160-$170 on the build, including the body, c-mount adapter, pistol grip and Pentax Lens (which I won for a steal on eBay for $40)!

    THANK YOU SO MUCH TO EVERYONE HERE FOR HELPING ME GET TO THIS POINT!!! ?

    And if I can be of any service with my still limited knowledge...I'm happy to help anyone!!

    I’ve been messing once again with using my EOSM as a Digital Super 8 camera and I’m pretty happy with the results. 

    For the video below I used the following setup.

    6mm f/1.2 Pentax TV lens (paper shim between lens and C mount-EOSM adapter, for infinity focus)
    Tiffen Digital Diffusion 5 filter (reduces moire artefacts)
    EOSM with latest ML build
    18fps override (exact)
    5x zoom
    12bit lossless RAW
    4:3 aspect
    1440 x 1080 

    i just used the aperture ring for exposure, rather than ND, as it seemed more authentically consumer Super 8.

    This video has effects applied - FilmConvert’s Super 8 grain; FCPX native “aged film” effect applied very sparingly for jitter and a little dust; a telecine’d Super 8 black frame (keyed over footage). If there is interest, I can post the ungraded footage.
     

     

    I love this! Thank you for the setup specs. I do have one questions though.  I understand setting everything up in the ML backend...but does it matter what you tell the EOS's software to film in? 1920x30, 1280x60, 640x30, etc? OR does the ML software take precedence and picking a framerate on the EOS itself have no effect?

     

    THANK YOU!


  5. Do you know what build and settings were used for this first video? I would love to get to that. Thank you so much! First time putting ML on my EOS M and even though I've been a photographer and built my own computers when i was 15...I still find this software a little alien and confusing at the moment.

    Here's a very quick test I shot with a Schneider / Beaulieu Optivaron 6-66mm f1.8 super 8 lens. 12-bit lossless, continuous shooting at 1392x1028 resolution. You can't really go higher than this resolution without getting excessive vignetting, and 4:3 aspect ratio is definitely the way to go with this lens. 

     

    Also here's a test with an EF-M 15-45mm stock lens, this time at 1792x1030 resolution. I wrote the music on ableton live for both these videos.

  6. Does anyone know if the Angenieux 6-80mm 1.2 C mount would be to large or heavy to attach to a c-mount adapter on the EOS M?

    Does anyone here have ay experience with this lens? Is it better to wait and find a 6-66 in either Schneider or Angenieux?

     

    Thank you so much!

    I love what you did with the Schneider...but how did you get it to mount to the M? Does the 6-66 come in an L Mount and you maybe got an L mount adapter? Thank you so much in advance!
