Raw Video / Re: Raw video on 5DMK2
« Last post by Boygetslost on January 12, 2021, 06:40:56 PM »Thanks everyone.
I actually went back to the last nightly build from 2018, for stability issues, one of the experimental builds I was using seems to corrupt files every now and then. I am only interested in using 14bit raw anyway.
I am having issues with my external monitor, sometimes I get pink flickers for a second and my last batch if clips had flickering issues that ruined them.
Is there a problem with the 5d2 and using an external monitor in raw?
(Both the experimental build and the older nightly build, seemed to cause some issues when I plugged my Cinieroid HDMI EVF/monitor).
Thanks
Chris

Yes.

« Last post by Danne on January 11, 2021, 10:22:31 PM »Yes, and after some more testing ZEEK also had some not so stable recordings with his 512gb card. He did some tests in a pm I sent.
I noticed also I am getting a few frames occasionally with 16:9 preset with full real time preview anamorphic. It only needs a little reducing of height to get fixed so I´ll test some more when I get the chance.

Some cards are lucky, like as ZEEK's Sandisk Extreme PRO 512 GB 170 MB/s card, unfortunately buying an Sandisk Extreme PRO 170 MB/s with 512 GB capacity isn't a guarantee to make 240MHz preset work on EOS M.

No
As I just thought it up. As I say, it may not work.
The jiggle is simply moving the lens from the point of focus to another point, and back again; ie the image is always taken at the same point of focus. I was hoping that engineering tolerances and mechanical imperfections in the lens MAY shift the image relative to the sensor each time.
The first approach, if you can, is to use handholding to achieve SR bracketing, which will guarantee image to image pixel shifts.
If jiggling doesn’t work, you still have the noise reduction brackets ;-)

« Last post by Kharak on January 11, 2021, 09:19:54 PM »Hey everyone, I have been using my 5d2 with an external monitor and I have found that the records times are slightly reduced.
I have Global draw set to turn off when recording and I don't have the sound module.
In other peoples experience, is there any settings I can tweak to squeeze some more performance out of it?
Cheers
Chris
You can lower the resolution slightly until you reach continues or satisfactory record times, but this will crop the image relatively ofcourse
or lower the Bit Depth.

Focus jiggling is a non proven way to do super resolution and based on the 'assumption' that moving the lens focus between images may (sic) create small image to image movements at the sensor pixel level, eg a few microns. As I say, this remains unproven. However, if you can't carry out 'normal', handheld super resolution bracketing, eg because of shutter speed, then focus jiggling may introduction enough image to image jitter to allow you to carry your super resolution processing. If it doesn't, at least you will be able to reduce the noise in your image, ie by sq.root(n); where n is the number of images taken
I think this sounds very interesting, but I am not getting my head around this "jiggling", to me, it's a guy gently kicking his tripod. Not sure if I am understanding this right, but do you shake the camera a little? As in artificially creating a Pixel-Shift image?

This 'new' MUSIC script is aimed at those interested in noise reduction or super resolution bracketing.
As usual I welcome any feedback on the script.
