General Chat / Re: Should I get a 6D?
« on: April 25, 2015, 04:52:50 PM »
I have to say that I'm VERY disappointed by my 6D and video-wise, I would go so far and say that only ML makes it somewhat usable. The aliasing and moiré is extremely bad. I have had situations where I had to throw away whole cards full of material because it was shot inside in a room with fairly normal structured wallpaper. Yes, low light is pretty ok but that aliasing and moiré is insane. Until I have the money together to buy a better camera, I help myself in really critical situations with using ML 3x crop mode and a wide angle lens which helps a lot.

But... Here's an example for low light. Shot in h.264 with 24-105L f/4. It was pretty much night and the weather wasn't great.


In the Finnish version you can see the moiré and aliasing problems in the background of the interviewed girl. That's not ISO noise, that's moiré and aliasing because of the structured wallpaper...

Magic zoom works for me.
But it is mutually exclusive with crop mode.

Found a way to reset the chips. After the problem occurred with 2 more batteries, I tried sucking the batteries dry with my LED lamp and then recharging them and that worked. It also seems that it wasn't related to pulling the batteries. It seems, the charger doesn't reset the chip when the battery isn't completely empty when inserted into the charger.

@Danne:
Very nice! You probably still used a relatively long lens, didn't you? The goshawk seems completely undisturbed by you. If you like nature / animal photography, did you notice my "The girl and the wolves"-film that I posted last year? It starts Finnish but most of it is in English and we have some very cute scenes :). I'm currently trying to raise the budget for a second part.

Yeah, ML is amazing for this kind if stuff! Especially the crop mode helps a lot if you don't have crazy expensive tele glass.

All recorded in MLV 1472x626 on my 6D with 24-105 f/4L with or without Vivitar 2x adapter. Used the above script to convert to Prores and except for the Magpie video where I pulled up Gamma a little, I didn't do any corrections in post. Upscaled to 1920x818 when rendered to h.264.

Edit: The WB is almost perfect. On my monitor, the weather sensor appears in exactly the same tone as it does to my naked eye.

Actually, I don't... Footage looks still pretty good. Still in experimental phase, though.
Code: [Select]
#!/bin/bash

FPS=$1
SCRIPTPATH=$( cd $(dirname $0) ; pwd -P )
LUTSDIR=${SCRIPTPATH}/LUTS
if [ ${2} ]; then
  LUT="-vf lut3d=${LUTSDIR}/${2}.cube"
fi

OUTPUT=$(echo ${PWD##*/} | sed "s/\.MLV//g").mov

if [ ${FPS} ]; then
  dcraw -a -c -H 0 -6 -W -q 3 *.dng | \
  ffmpeg -f image2pipe -c:v ppm -r ${FPS} -i pipe:0 \
  -c:v prores_ks -profile:v 3 -vendor ap10 -pix_fmt yuv444p10 \
  ${LUT} -y -r ${FPS} ${OUTPUT}
else
  echo Give framerate as parameter!
fi

Gotta play around with that. I do generally set WB with a graycard at the beginning of filming or if the light changes, even before each take. As for audio, I usually record externally, so I anyways have to sync that by hand.

In my automator workflow cr2hdr-r Andy_600 provided this workflow with three different luts. They are inside the download package and the intention is to use them with ffmpeg to ProRes workflow. Although lowres to suit ffmpeg lut handling they work very good indeed.
Thanks! The lin to rec709 LUT is pretty close to what I had in mind, comparing the result of ffmpeg without LUTs to that.

I would consider Resolve Lite if there was a Linux version - and I mean a version that is INSTALLABLE on Linux and not a whole new Distro. I played around with it some time ago in a virtual machine but that's obviously no solution for serious use...
At the moment, I'm still very much on an enthusiast amateur- or hobby level and I mainly edit with kdenlive. I have been considering switching to Resolve as a BMPC4k ist somewhere on my wishlist and - at least according to the advertising - Resolve is capable of more than just color correcting, i.e. proper editing, at least basic stuff like transitions, chroma key, etc. But then there is also a very steep learning curve as the Resolve GUI is completely unintuitive and has nothing in common with any other software I know. Kinda like Blender in the graphics world :D.
And I would need to invest in another (maybe even 2?) big screen plus some serious NVidia power to be able to work fluently.

Raw Video Postprocessing / 3D LUTs for MLV -> Prores?
« on: March 20, 2015, 08:13:20 AM »
Thanks to Danne, I have a working script to batch-convert MLV-files to Prores with ffmpeg. The result is pretty REC709-ish which does leave some room for correcting and grading but I'd prefer a little flatter image. I tried using MLRawViewer's LUTs for C-log, SLog, etc. but those are 1D LUTs and ffmpeg only works with 3D LUTs.
Does anyone know some good (free?) 3D LUTs for MLV -> Prores conversion? Or maybe somebody could spend a few mins and convert the MLRawViewer 1D LUTs to 3D?

Nope, in h.264 it simply ignores the zoom button.

Edit: It would be very cool (and helpful) if it was possible to cycle through the zoom modes in crop mode without leaving crop mode, so one could switch e.g. between 1x for framing and 10x for focus verification back and forth.

Found the crop mode hangup. Not the post but... If you press the zoom button while recording, the 6D will freeze and you need to pull the batteries.

When I write always, I mean always... It stays 100% right until the camera shuts down due to low voltage...

It's only this one battery. I have a bunch of others and those still work fine.

General Help Q&A / Reset battery chip?
« on: March 17, 2015, 04:43:57 PM »
Hi,

I had my 6D freeze on me and pulled out the battery. This specific battery now always reports 100% charge and the shutter counter doesn't reset to 0 charge. Is there any way to reset the battery chip or can I throw the battery away now?

Share Your Videos / Birds (6D crop test)
« on: March 11, 2015, 08:27:29 PM »

Just shot a few birds to test the crop mode of Magic Lantern on my 6D. Recorded with 24-105 f/4L in 1472x626 MLV raw, upscaled to 1920x818. Edited with kdenlive.

Is it possible to get more than 3x crop? I noticed that when I switch to 10x zoom, it still records 3x crop... The newer cameras have a lot of pixels... 1:2 or even 1:1 could be cool...

Well, I tested today and it works great... Happy to have been wrong! That's gonna be great for shooting birds at the feeder!

Ofcourse, why don't?
Because IIRC it's not supposed to work, locks up and bricks the camera...? And I remember somebody writing that the 6D doesn't have a crop mode...
Are we talking about the same thing?

Ah, sorry. EOS 6D, EF 24-105 f/4L, h.264. Heavily used ML's general features like zebras, peaking, cropmarks and ETTR hint. In this case, also the intervallometer.
Cut and grade with kdenlive.

@Sirup:

I would suppose that Walter meant that the 6D can shoot in 4K, it can shoot raw and it can shoot at 24/40fps, just not all at the same time.
If you use the intervallometer, you can perfectly well shoot a timelapse video in 4K/raw, just not 24/30fps real time. You can also perfectly well shoot in 24/30fps and in raw, just not 4K.
Only when you want to do everything at the same time, i.e. shoot 4K/raw at 24/30fps, you get into problems because the 6D's hardware simply can't do that.

Archived porting threads / 6D motion detection
« on: March 06, 2015, 02:46:29 PM »
Motion detection only seems to work by exposure. When I choose "difference", the detection box in LV is black and ML never detects any motion.

Besides, how important is the temperature? I had my 6D on a tripod aiming at the bird feeder with motion detection on and after about an hour, ML showed 60°C temp on a red background. I shut the camera down - just to be on the safe side... Any idea what kind of temperature the 6D can tolerate for how long?
