Is it possible to merge the wav with the video, creating a prores using ffmpeg?
cheers!

Feature Requests / Digital ND-filter (lower ISO)
« on: September 13, 2012, 02:43:16 PM »
Is it possible to create even lower ISO for film (like a virtual ND-filter) than current ML? This would be useful for filming with 1/24 shutter and 1.4 apperature in daylight without overexposure.

The quality could improve (if you do the math) but as you say probably impossible to control what lines to include from the cmos read.

Not my own but it's great for showing the differences changing the bitrate can have on footage

Hm.. I would almost say that the 0.3 looks better than the 3.0. Especially when maxing the saturation (3.0 gets blockier than the 0.3). There might be some sharpness in the black text, but not really sure its due to the codec (since I assume these shots must have been recorded separately?).

I think there can be better test though, much of the picture is fairly static (which is a good thing for a codec). Maybe the difference would be greater if the whole picture was moving... Im going to do some tests.

This would pretty much be solved by "Turn off LCD when recording when press unlock button". Close this one.

I cant remove my post...

User Introduction / Sweden - Poromaa

Hi there!
I have been an amateur photographer/filmer since 10 years back and a user of ML since last xmas.
I am a engineer in computer science, that has been working within finance for a while.
2 weeks ago I quit my job to focus on film for a year.

I just love what ML has done with my camera, and as soon as I get time I will start looking into the code and see if I can contribut (have not coded ARM or much C though...)
Anyway, Im full of ideas and very driven. If you live in Sweden don't hesitate to contact me if you need help/want to do some project together.

Upcoming project: Trip to Kebnekajse (highest mountain in sweden). Will try to tell that story with my 5D mkii

Btw it's 'line skipping', not 'downscaling'.
Ok, thanks! But the idea would then be something like skipping fewer lines between every recording of the 1080 lines. (scanning a 2.35 cinescope, rather than scanning the whole 16:9 letterbox)

just turn on crop marks in overlays.  use the built in cinesco2 or make your own.

Well, when you do, the movie is still recorded with 16:9 frame, and in post you will have to throw away 263 lines (1080-817). The result would get lower resolution than if you do it the way I have described above. My proposed idea (if it is possible to implement) would instead use all the 1920x1080 pixels to cover the 2,35 cinescope output. It would be like having a anamorphic lens on the camera without having the hardware.

It should be possible to split the MOV-files from the 5D without re-encoding.

Shooting from the waist - There seem to be some code for triming Mpeg4 files in this application:
http://ffmpeg.org/

Under "projects" there seems to be a ton of applications using parts of this framework for video-related tasks (many of them seems to be very small)

You are probably right, but if it was possible you would get alot higher quality (817->1080) on the y-axis if you plan to use the end result as 2.35 ratio

Oh, nice feature. I cannot find such feature on my 5d mark ii

Feature Requests / 2:35 movie format
« on: July 30, 2012, 01:46:13 PM »
The sensor on 5D mk ii is 5616x3744. When recording the camera crops the image to a 5616x3159 (16:9), scaling it down to a 1920x1080. As I understand the format of the final file will always be 1920x1080... but...

Would it be possible record 5616x2390 (2.35) and scale down to 1920x1080?
This would enable the user to rezise x-axis to a 2538x1080 keeping more information in the image (since no post-cropping is needed), and also not waste any compression on things you plan to crop away in post.

Note, Im not asking for a different output than 1920x1080... just different reading from the cmos?

Feature Requests / [DONE]Timelapse Powersave (Ecomode?)
« on: July 30, 2012, 09:50:30 AM »
It would be nice to have a "powersave" function in the fps overide setting. I for example only use the "turn off LCD" when doing filming timelapse, but then when I want to shoot regular I usually want to turn off the powersave function again.

It would be nice if the power-save-function was a sub-setting for just timelapse and fps-override.

 When shooting timelapse with the intervalometer, eco-powermode would be useful that does not even show any picture at all unless (for example) the LCD-sensor is triggered during a take. In practise this would mean a black LCD during all shots unless you hold your hand close to the sensor/press a button?

Feature Requests / In-Camera movie trimming
« on: July 30, 2012, 07:43:30 AM »
I do nature filming and sometimes I have had the camera on for several minutes to capture something in 4 seconds (Snake peeking out from a hole). However, my memory card is filled pretty fast, and sometimes I have to remove a scene with good stuff simply because of need of storage for other interesting happenings.

What I would need is a simple way of cutting down (extract the interesting part) in movies shot in camera. That would then allow me to not have a computer/100 memory cards with me out in the field. I wouldn't need accuracy here, but cutting on a keyframe would be good enough.

Keep up the great work!
Cheers

Just forget what I just wrote... I have read around some more now. Seems to be impossible anyway :)

Keep up the good work!
