Incredible! I noticed you work with the same actor in several films. Can you share some of what you learned from that experience, like maybe do you find it helps you get the performance you're looking for?

Share Your Videos / Windows to the Soulmate - 7D w/ VAF
September 29, 2016, 09:13:07 AM
I found out about a video competition a few days before the deadline (end of September), so I was up last few nights working on it. The rules are: it has to be less than one minute long, and the theme was "the eye."
Here is what I submitted:

Starring my wife and myself :)

I wanted to do a sound mix and a million other things- but there was no time/budget.

Agreed, great stuff there, loved it!

Really liked the cut at the beginning with the musician playing in the bedroom. How'd you do the sink shot btw?

Great work!

I saw this topic is super old but still relevant.

On a laptop and slowish drive this workflow didn't really work for me - opening multiple files in camera raw through bridge hung and crashed.

However, I realized a good workflow using ae and bridge, if you just want to reference a frame other than the first in a sequence, yet apply the final changes to all...

1) open bridge and navigate to the frame you want to reference. bridge will give you thumbnails without needing to open anything, and it works fast enough to see content - so just scroll through

2) open that image in camera raw (right click -> camera raw...)

3) adjust to liking

4) save/export xmp file settings. Hitting "done" is okay to close, won't harm anything

5) now in AE, import dng sequence (camera raw will popup there)

6) import/load the saved xmp

Basically using bridge for what it's good at (browsing file system and opening single files) and after effects for what it's good at (everything else)

General Help Q&A / Crop mode primer?
September 25, 2016, 05:24:58 PM
Is there a link somewhere to a primer on what crop mode is - and when one might want to use it?

More specifically - I'm wondering if it will help me turn a non-macro lens into a sort of macro lens, e.g. to get imagery which is closer to the subject and still be in focus than would normally be possible?

When developing a module, is it necessary to compile, install onto card, boot card onto cam, enable module, run it, rinse and repeat?

More to the point- I'm wondering how the devs approach iteration and testing. Do you build a bunch of tests and hook them up to buttons or whatever and then run it? e.g. write larger chunks at a time, test more rarely?

Basically just looking for advice about iteration and approach to coding ML for more fun :D

Thanks for your help again!

Seems internal/manual will be much easier and better than an external cue. Is the following right?

Assume "sync value" is some measure such that two cameras with the same sync value can be said to have their sensor recording happening simultaneously.

Module: Config menu allows manual input of target sync value. Upon recording, it will automatically re-sample the internal sync value and add or subtract from the FPS override until internal value matches the target. Once it hits that target, it optionally instantly turns off FPS override (alternatively this is an ongoing process). It can output to screen or maybe blink the LED or something to let us know when it hits the target the first time.

If that's wrong, or you have a better idea, I'd appreciate your insight. Similarly, if it's right, do you know the best method for getting that "sync value" (e.g. (real time - vsync time) would be great!)?

I'd take a look at stream ciphers which allow random access... Salsa20 might work, I believe you can set the key from any position of 8-byte blocks (and so you can just seek anywhere, get previous block, and ignore the overflow)

Whoa... lots to digest... thanks for the in-depth feedback!

I'm still missing a few fundamentals. Is there a primer somewhere on the relationship between recording rate and LiveView clock? I would (naively) think that recording happens from one clock, and LiveView tries to keep up with that and drops frames as needed... but I guess I'm wrong :)

The last option sounds really good, especially if liveview is truly a 1:1 match with what's being recorded. If it's good enough to the eye on liveview - it's good enough to the eye on playback :D Though I'd imagine matching those in the lcd display would be really hard... would probably need some dual-hdmi monitor which allows overlays, no?

Following up on that option - if one is going at 24 fps and then I adjust the other to be 24.5 fps till they match - won't they drift out of sync again? Can you explain a bit more about how you see automating from vsync hook (is it to grab the timing from one and print it to the screen for setting on the other?)

Duplicate Questions / Reading custom IR?
August 31, 2016, 08:25:44 AM
Would it be possible to read custom remote control codes?

I'm thinking for example to setup an Arduino with IR output, and be able to send new commands the the 7D to be processed with ML. Not the builtin record/stop/etc.

For starters- even just to log "hello world" or whatever.

My ultimate goal is then to use that as some sortof syncing mechanism to do genlock (http://www.magiclantern.fm/forum/index.php?topic=1596.msg171511#msg171511) but one step pulse at a time! :)

Just getting my feet wet looking at the source... but how wrong am I thinking that raw_rec_cbr_started() could be patched to wait for an external cue... would that be enough for this to work? (at least for really good synchronized start, and hopefully drifts won't happen past that point)?

Oh, seems I misunderstood, the led blink thing was just for outputting a signal for each frame grab, right?

Once recording is going (e.g. green in RAW mode) is there a way to sortof tell ML "reset the clock now" ? i.e. so when both cams get the ir signal they'll forget about the current cycle and start over simultaneously?

General Help Q&A / 7D and Crop mode - remove VAF?
August 30, 2016, 10:30:09 AM
When shooting 1:1 RAW I understand the VAF filter is a huge bonus. If shooting in crop mode, should the filter be removed?

Thanks!

I'm starting to put the pieces of the puzzle together from this and other posts... from http://www.magiclantern.fm/forum/index.php?topic=16112.0 and http://www.magiclantern.fm/forum/index.php?topic=8912 and chmee's comments above, would the following work:

1) write a module to parse readout on the ir-port

2) given the target command over ir - tell the mlv-rec module to blink the LED

3) use arduino or something to output ir to both cameras at consistent framerate around 24-30fps. Something based on https://github.com/z3t0/Arduino-IRremote or  http://sebastian.setz.name/arduino/my-libraries/multi-camera-ir-control/ might work

Is this the right idea? If IR is too flimsy, since recording times in RAW are generally short anyway, might be enough just to do that for start points - or maybe manually trigger "re-sync" every couple minutes. This assumes the above makes sense of course

EDIT: is USB an alternative or is it too slow? Something like https://github.com/felis/PTP_2.0 may come in handy...

Tried to delete this but the forum wouldn't let me... obviously 7D ML is the way to go if genlock is an option! Following up on that here: http://www.magiclantern.fm/forum/index.php?topic=1596.0

I'm hoping to shoot 3D soon for a project on the GearVR. My camera budget is around $1000-$2000. I'd like to get advice from y'all about the wisest route to go... mind you I live in Israel so shipping fees, customs, headache, are all relevant factors. Here's what I'm thinking:

I currently own a 7D. It's served me well over the years and I am incredibly grateful to the Magic Lantern devs for breathing new life into it and helping me pimp it out to squeeze best possible footage out of it. My kit is ML Raw, Komputer Bay 64GB cards, and VAF-7D Mosaic filter. I have two lenses with it, the sigma 30mm f/1.4 ex dc and a jupiter-9 with m42/ef mount.

So this gives me a few options:

1. Buy a second 7D and matching lens to the Sigma (will be easiest to match focus and predict close look) and a genlock signal generator. My question is - does ML support genlock on the 7D somehow?

2. Buy the DualHero rig and two GoPro Hero+ 3 Blacks, as well as the 5.4mm lenses for each. Probably don't pay for the "pink fringe" removal. This is a pretty niche area so feel free to ask if google doesn't tell you what some of this is about. This would basically just be for this project and then not really do much for me past that.

3. Buy two Black Magic Micros, genlock sync generator, and lenses. This goes way beyond my budget - so this option means selling my 7D kit

Note that I do want to still be able to shoot regular stuff from time to time. Option 1 and 2 allow me to do that with my 7D. Option 1 will let me do dual-camera shoots even. Option 3 means I shoot regular stuff on the Micro.

I'm bringing this question to the Magic Lantern community, mostly to see if option #1 is viable. If it is, I think it's probably the way to go, since the larger sensor size of the 7D will give me more freedom in general than the Micro....

if you press zoom again it turns color while pressed... ouch, turning raw on and off would also be time consuming for the way I like to work :\

Need to get me one of those EVF things or a large monitor so I can judge focus more easily ;)

That's the point :)

I like to go back and forth between zoomed in (to check focus) and zoomed out / regular (to compose the shot).

With ML installed- the regular (zoomed out) view is great since I can see the scene as-is and also get meters, but the zoomed in view is not great since there's a delay (esp when going back to regular), it doesn't go to 10x, and it defaults to b&w.

I'd like the zoomed out / regular view to be ML with all the bells and whistles, but zoomed in (both 10x and 5x) to be native canon- and to be able to quickly switch between them.

Is that possible?
