Works in 5D2!

Quote from: sashk0 on April 11, 2014, 11:16:29 AM
Dear author, I've just tried it on my 5Dmk2 with magiclantern-Nightly.2014Apr02.5D2212 and it failed to load. I guess it's a bit out of date. do you have update for newer versions?

Yes, it is outdated :p
Unfortunately, I don't have any updated module. However, I'd recommend using regular Intervalometer with "silent picture" enabled ( to get a similar output.

Hey dhilung, sorry unrelated to the module but I was wondering what did you use for panning the video during the timelapse?

I used a Radian ( with an extended arm (like this

Hey! I'm new to the forum, but a long time ML user.

I downloaded this module, and it works great for timelapses (thank you so much!)
No shutter actuation, and RAW frames. It's just brilliant.

However, I was looking to do a timelapse in the night, and have stars move about. I noted that the FPS can't be changed and I was not able to capture the night sky with stars visible. I tried using FPS override but that brought me no luck, either.

So I was wondering -- would it be possible to decrease the shutter speed (ie go around 1-5 seconds per frame) when using this module? Or is there any other method I could follow to have a night timelapse (without shutter actuation/with RAW frames)?

Sorry to hear that it didn't work. Unfortunately, the exposure can be extended only as much as the FPS override allows. You might want to try a high ISO and a fast lens, or fall back to the real shutter actuation. 
Brilliant work!

Interesting black-level drift analysis and correction.

Btw, I also put a mirror at
Nice! I like the audi idea.
It needs to be set while in 'movie mode' (like aspect ratio setting) to be effective. I know it can get confusing :)

Sounds good. I'll look into that. First thing will be to fix the timing issue though.

not sure, but maybe due to the single container file? :)

Exactly, as a time-lapser, I can tell that life gets way easier during post production :) since I don't have to remember or hunt down 'that' transition of sequence. I can treat each timelapse session as a movie session (which essentially is), and directly work on it (e.g., directly import to AE using Ginger HDR etc.)

But again, technically, both ways give the exact same RAW data. This small modification was for a personal convenience, thought might be useful to others. I'll see if making a separate module makes sense.

i found the line skipping parameter already. its ADTG register 0x800C.
but when changing it, the screen seems to "overprint" multiple times.
looks like the bottom scanlines are printed over the top as the image gets larger in vertical dimension.

didnt find the register that handles line count / end address.
@g3gg0 that sounds exciting!

Could you post a diff file of your modification?
Better if is it against last commits. :)

Thank you.

Sure :) Here is a diff to the last commit.

I think in the current implementation of intervalometer, the wait time for the shot intervals has the time resolution of seconds. Also, they are less accurate for finer intervals because of the random 'sleeps' introduced within the loop.

If the raw_rec resolution is okay for your project, frame-skipping option might be helpful for you (
Currently, it has interval choices of 0.1, 0.5, 1.0, 1.5 .. etc (in secs), but you can easily change the code to include your desired values.

Why not just enable the intervalometer and silent pics? You get DNGs straight from the camera.
Yes, that also gives similar results, and I support having one implementation for one feature. However, as of now, I still see at least two advantages while using frame skipping 1) better fps precision at low frame intervals (<2s) 2) easier file management (a single file per timelapse session). Not to mention that all the current and future raw video related features, such as live cropping, can be enjoyed in a timelapse session.

Is it also available on the 5DIII ?
I have not tested, but I think it should work just fine in 5D3.
This is a small change in the raw_rec module to enable timelapse video. It simply skips frames during the timelapse frame-interval, hence the slow card I/O is no more an issue.

The 'FPS override' somewhat gives similar results (usually desirable in a low-light condition). However, this frame-skipping option gives us better control over the FPS and the shutter-speed for timelapse, specially in a bright-light condition. It can still be used along with the 'FPS override'.

Now for those curious if rolling shutter in Raw video is different as in h264.

I think the actual image acquisition pipeline of DIGiC is the same for both cases until the RAW frames are copied over using EDMAC (raw_rec) or encoded in H.264 (normal). This means the rolling shutter effect should be the same.

This is an awesome work!

Shooting such long time-lapses in RAW... that is epic! I'd expect a 4K version of the movie :)
Great work!

What ND filter(s) did you use?

Great art work! 
what lenses did you use?
HDR Macro - interesting combo. Liked the color and sharpness.
Nice work! I like the motion effect with 1/8.

I happened to try similar time-lapse in the same road! not as long as yours though. I also tried to stabilize it in AE using trackers, however, due to the distortion of the wide lens, stabilization with just an XY-plane-correction was not effective.

And how does this work on mac?

First install 'enblend' using 'MacPorts' (this will install 'enfuse' command) then run the HDR script.

Very good job!
But the color is strong saturated and does not look natural, like a cheap camera

Thanks! and I appreciate your creative criticism. Vividness has been my artistic choice, and I use CPL to capture as much natural color as I can to start with.

I wish I could read this :) coz I'm also curious about the previous question. Also, If you don't mind, could you tell us what stabilizer did you use?
