Thanks, Alex

So I tried a second one. I ramped the ISO from 100 to 1600 over the course of a 12-minute period, which was way too quick, it seems. I was using a fully manual lens again, so this was the easiest option.

I've linked the resulting video, and during the middle the sky does some weird grey shenanigans. I think this is from it being blown out, and then having the highlights pulled down in Lightroom. I gave up too much to the highlights, too, I think. Not much sky detail at all.

Next time I think I'll just let AETTR do its thing, for as long as varying shutter speeds don't affect your output, you can really get a lot out of going from say, 1/60 to 10 seconds.

dmilligan's deflicker script worked well again. I ran 8 iterations in Bridge CC. On my previous attempt I gave it 15 and it still said more could be required. This time it took the 8 and was fine with them. I wasn't able to get the deflick.lrplugin working in Lightroom, so my workflow thus far has been Bridge -> Lightroom -> After Effects.

Anyway, it seems like perhaps AETTR could benefit from having some more specific parameters built in, like an aperture and ISO option. Essentially taking the ramping functionality from the adv.int. You'd set your desired highlight, midtone, and shadow levels, and then let AETTR do its thing while having access to more than just a shutter ramp. Add in an 'always maintain exposure or else increase/decrease' (depending on sunrise/sunset) option, and you're gold! The deflicker plugin seems to work really well.

A very powerful tool, this! I think it'll take a little (lot) more fine tuning on my part to set the ramp timing correctly.

So I've spent some time going through the AETTR, timelapse deflicker, and advanced intervalometer threads and have (inevitably) come away with a few questions.

I had AETTR on, as well as the XMP files for deflickering in Bridge, and had a few keyframes set (using global time) around sunset.

I had the max AETTR shutter time set at 1/15 ( I think), although the max keyframe-set shutter time was 1 second. I was using a fully manual lens, so only adjusted the shutter speed and ISO.

It seems that AETTR overrides the keyframes to an extent, as I have adjacent images, one taken at 1 second, and the other at 1/15.

Looking at the images, it seems like AETTR does a pretty good job at metering the scene and maximizing the exposure, performing it's own sort of 'ramp' as it does its thing. As long as you're OK with varying shutter speeds and have a fairly consistent light fall-off, then could one only set this and not set any keyframes?

I loaded all the files into Bridge and used dmilligan's script to deflicker, which worked really well! However, as could be expected, the images shot at 1/15 were pushed really hard to match exposure, and so are really noisy. I'm going to try the Lightroom plugin for the next one I do. It works great. Thanks for this, dmilligan.

I'd really like to set AETTR, have the XMP files to deflicker in post, and just use the basic intervalometer settings, leaving the max AETTR shutter time at something pretty long, like 10 or 15 seconds. But it seems like you can only ramp ISO (and aperture) with the advanced intervalometer. I suppose that if you're going from bright daylight to dark, clear night, you'd really want to dial in an ISO ramp then, too...Any way this could be incorporated into the AETTR settings? Or am I missing something here...

Regardless, I was really impressed with my first-time results.

Raw Video / Re: Raw and crop mode

Hi capitanazop

I've only just started playing around on a 600D myself, but this is what I can tell you so far...

Keep the Canon menu video settings at 1080p30. You can still shoot 24/25/30 fps by changing the frame rate in the Magic Lantern menu.

The highest raw option I have is 17xx by xxx. I don't have the camera with me right now, so I'm not sure of the exact numbers. Going into the 3x crop mode (enabled in the Canon menu settings and then applied in Magic Lantern by pressing the DISP button up top and the Zoom+ button) gave me a slight bump...Still 17xx pixels wide. It was only 30 or 40 more, as I recall - the next bump up in the resolution settings. I'm sure the Excel table floating around on here with all the cameras and their raw capabilities showed something higher, though. Oh well.

Under the raw video subheading in the ML menus, press 'Q' to enter the detailed menu and select your resolution. You're saying ti's limited to 960x480 there? That would be strange, as mine lists even the resolutions I can't record for more than 1.5 seconds.

This post has been dead for a couple months, but was just what I was looking for!

I've just started playing around with raw video on my 600D. I've been extracting the DNG files with raw2cdng, then opening them up in Lightroom, choosing one mid-sequence to edit, editing it as I would a regular picture, and then syncing those settings across all the remaining frames.

Then I export as originals, and stitch them back together in VirtualDub with the Cineform codec at max quality.

I've been using Lightroom for years so I feel very comfortable with it. I also have Photoshop but rarely use it. I don't have any other Adobe programs and use PowerDirector 14 to edit video so this seemed like the easiest workflow to me. I admittedly haven't done much at all with it yet, but it seems to  work well and it fairly straightforward for me.
