Camera-specific Development / Re: Canon 700D / T5i

Isolated experience.  Just because it works on your system doesn't mean it works universally.  It's quite buggy on Windows 8.1

Try raw2cdng (http://www.phreekz.de/wordpress/2014/04/magiclantern-raw2cdng-1-5-0/) and make sure 'chroma smoothing 2x2' is enabled.  Works for my 700D mlv files.  Raw2cdng is a little finicky though.  Only the latest few versions have chroma smoothing, and among those versions, 1.6.3 was the only version that worked properly on Windows 8.1 for me (ironically the only one labeled 'buggy') and even that version sometimes rejects the mlv files for whatever reason.  If that happens just close and re-open the app, make sure you are dragging the mlv files in from your desktop instead of another folder.

Raw Video / Re: Blue and Red pixel in RAW mode
January 09, 2015, 06:18:20 PM
Welcome to the forum.

In the future, when you have an issue, please search the issue first, either on here or on google.  This is already a well-documented issue with established solutions, no need to create another thread about it.

But while I'm here I'll explain it since I also have a 700D and had the same problem.  This pink and blue pixel problem is shared by the 650D, 700D, and EOS M.  I believe the problem may have been fixed with the 650D or EOS M (or both) due to some changes to the source code, but unfortunately it still hasn't been fixed for the 700D and until a dev updates the build, there's no way to avoid it.  However, the dots can still be removed.  Walter suggested "Pink Dot Remover" but the only problem is, Pink Dot Remover doesn't support the 700D.  Here's what I do: Download raw2cdng (http://www.phreekz.de/wordpress/2014/04/magiclantern-raw2cdng-1-5-0/) and drag your mlv/raw files into it (assuming you still have them), ensure "chroma smoothing 2x2" is selected, and then convert.  The converted DNG files will have no more pink or blue pixels.  If you've already converted to DNG and deleted your mlv/raw files, you're probably SOL.

Unfortunately raw2cdng is finnicky with Windows 8, and the only version that worked for me was 1.6.3 (oddly enough, the only one that's labeled 'buggy') and even that one doesn't always cooperate.  Only the latest few versions support chroma smoothing, so hopefully one of them works for you.

That video was shot with a 1/60 shutter.  Aside from the spots where I had to reduce the Twixtor effect, would you say the motion blur is acceptable?

I really wonder how can Canon put some much limitations to its cameras when they have the Panasonic GH4 as a competitor !  ::)

Canon owes the ML devs a ton of money.  If it wasn't for ML they would surely lose a lot of sales to their competition.  Right now, the 7D Mark II and GH4 are only $100 apart, and with the 7D2's lack of ML, the GH4 craps all over it.  Even with a ML port the GH4 is probably still the better deal.  I've never bought a camera over $1K but if I was choosing between the 7D2 and GH4, I'd unfortunately probably choose the 7D2 purely because of the investment I've made in Canon lenses.

Look at this: https://www.youtube.com/watch?v=nH5fafQQddg

If you ask me, I'd say the compressed GH4 footage still looks better than 5D3 raw, and obviously destroys the compressed 5D3 footage despite a bit rate that's only slightly higher.  Canon's compression is so disgusting, you'd think in a 1080p YouTube video, 91Mbps 1080p footage would look better than 100Mbps 4K footage.  But no, the GH4 can record 4x the amount of pixels at almost the same bit rate with much better detail.  And not to forget after all that, the GH4 literally costs half of what the 5D3 costs.  The only advantage the 5D3 has is sensor size.  If the 5D3 didn't have ML? lol.

Yes, I understand the whole "cinematic" argument but IMO it's easier to soften in post than it is to sharpen.  Removing detail will usually work better than adding fake detail.  Still photography is a whole different story, and obviously DSLRs are made for photography first.  But I can't advise any aspiring videographer to choose any Canon camera over a GH4 or a Black Magic or a Sony for video production.

In FPS Override, I can't seem to find the "high FPS" option nor can I overcrank beyond 60fps (even when setting 65 or 70fps).  Is this disabled/impossible on the 700D?

Sorry if this sounds like a newbie question, but just so I'm clear, is the reason that the 70D won't be able to record RAW video at 1080p because the SD controller can only write at around 40 mb/s and RAW requires faster writing speeds?

Correct, but that's only 1 of 2 reasons.  The other reason is the sensor.  Due to the way raw video is recorded (reading only 1 of every 3 lines) the maximum resolution you can read from the sensor is 1856x1044.  So even if it had a CF slot that could write 100MB/s, it still couldn't shoot full 1080p.  Which sucks, because the video these cameras shoot is already pretty soft, upscaling it will make it even softer.

Speaking of that, I wonder if the 3x crop mode will allow the full 1920?  It wouldn't matter for this camera, but it might matter for the 7D Mark II (same sensor).  If so, you could use a really wide-angle lens to get a full 1080p image at a reasonable FOV.

Yup.  48 to 24 is obviously a 2x slowdown, but you can stretch 60 to 24 for a 2.5x slowdown.  In Premiere, you'd simply put the 60fps clip in a 24fps timeline and stretch the clip by 250%.  You can can take any fps, even strange numbers like 63 or 79 and spread them out to fit exactly 24fps.

Here's a little video I shot just a couple weeks ago to experiment with slow motion:



I shot at 60fps, spread it out to 24fps, and then used Twixtor to stretch it to 12fps with interpolation.  Final result is 24fps with 5x slowdown.

However, good luck getting raw 60fps (or even 48) at any respectable resolution.  The 6D is unfortunately limited to ~41MB/s, which is just barely enough to get continuous raw 24fps at full 720p.  You'd be much better off going with 720p60 h264 with bit rate cranked to 3.0x (that's what I did for my footage).

Share Your Videos / Re: Cheese Commercial shot in RAW
January 08, 2015, 03:26:00 AM
Beautiful shots.  That rack focus on the knife slicing that cheese block was my favorite shot.
Do you mind if I ask how much you would normally charge a client for something like this? I'm fresh out of college right now doing live sports gigs as my primary thing, but I'd really like to starting doing these kinds of short promotional videos on the side.  I just have zero business knowledge and no idea what to charge for something like that.

Any chance anyone can tell us where we can find the pre alpha build or is it not yet released?

Not publicly released, nikfreak sent it around to a few people, maybe they can share with you (I personally don't have it).

I'm also curious to see how well it'll perform with a Sandisk 32gb extreme pro (90 MB/s) ;)

Probably the same as a 50MB/s card  :P

Whoa, I thought this whole time the squashed video height in Canon 720p mode was intentional to allow cameras with slower storage to get wider resolutions.  This isn't intentional?

It's really strange that Canon's default 720p h264 mode can record 60fps with no squashing, but ML raw in 720/60 mode is squashed even with custom resolutions set well below 720p and FPS set well below 30.  Assuming the 7D Mark II eventually gets an ML port, I wonder if that will be the first camera to record 1080p60 raw without squashing (given its 1080p60 h264 mode) or if it will have the same problem when set to 1080p60 mode.

bonjour a tous
je n'y connais rien mais peut être serait'il bien de développé une application android magic lantern pour piloté le 70d en wifi meilleur que celle de canon 
exemple intervallomètre   
remonté GPS directement dans l'appareil ....

encore bravo pour ce travail

Why.

Looks like the 70D VAF has just recently arrived, right in time for the ML port release! Good timing! Can't wait to see what kinda footage I can get with both ML and the VAF  :D

DERP.

Speaking of the VAF though, does anyone know if it has a different impact on ML raw footage compared to h264 footage? I'm not exactly sure how the Mosaic Engineering VAF works, and I'm not even sure I understand the differences in the way the sensor is read between raw and h264, but I know recording raw reads only 1 of every 3 vertical lines and recording h264 does something different.  Which makes me wonder if the VAF alters the image differently when recording raw?

Sweet, thanks!
#67
This is something I've always wanted to do on Canon DSLRs.  Being able to simply point at a white surface in movie mode, press a button, and instantly white balance to whatever the sensor sees at that moment.  If the camera isn't capable of that, I'd at least like to be able to use the click-wheel to adjust color temperature 100K at a time.  Would be a feature many film makers would love to have.
#68
I don't think it really works that way. It's not a 40MP sensor. Each pixel has two photodiodes that somehow split the incoming signal into 2 viewing angles and tell the lens to move until both angles align. At least that's how it sounds to me, Canon hasnt disclosed much on how exactly it works.

DV the journey of 1000miles, starts with the first step.  Here's an approach to consider.
1. What's the best upgrade chance?  Either 7DII, 50D, or 5DII. 
2. Get pics and measurements for all the three boards.  This is research by asking tech supports who sell the parts, for info. before you purchase.
3. Ask a tech support  for their opinion?  They probably have thought about this already, and may be able to point out any obvious pitfall.
4. Now if all is good, buy the one that fits into your 700D (for instance), the PCBs I found were not that expensive.  You may even want the tech support guy to do the install or write out the steps he would follow??? 
This is to minimize the risk, if you like H/w exploration you will eventually have to crack open a camera.
5. As for programming, that is probably not needed and if so that's what the ML team can handle.

Sorry Im too busy and have a shooting schedule for next few months. 
Besides I would want to upgrade a 600D, as that would be pure hacker glory to have it shoot FHD raw.  JM2C.

I think the time to explore the dual write s/w upgrade is after ML works reliably on the 70D.  Which I hope nightly drops soon occupy me. 




We'll see.  If I spend my time figuring out how to upgrade the SD slot and (only if it's possible) writing up a detailed tutorial, I'm only helping myself and a few other brave souls willing to perform surgery on a $1000 camera.  If I spend that same time trying to figure out how to write files from the camera out the USB port, and I'm successful, I'd help a whole lot more people.  I don't have much time for either one for at least the next month, and when I do have time, I'd sooner investigate the USB idea.

Gotcha.  Possible, but probably not practical for anything other than maybe black&white.

Thanks dmilligan.  I appreciate that you're willing to take the time and explain these things, it's a lot more helpful and educational than simply saying "no" with a snarky attitude like some other members of this forum will do from time to time.  I know that nobody "owes" an explanation to anybody, so it's nice having people who are willing to explain.

I was hoping that it would be possible to read every 2nd line instead of every 3rd line, but oh well! Marked impossible for now.

Browsing around the forum a bit yesterday, I found another thread in which writing data to USB storage instead of CF/SD storage was discussed.  A1ex commented on it and surprisingly didn't say it was impossible.  Judging from his tone of words it almost seemed like it would be that far-fetched of an idea, basically saying you could theoretically write data to both the USB device and SD card at the same time and merge the frames in post, just like combining the 5D3's CF and SD slots for 100+20MB/s.

I'll try to look into it myself, although my programming knowledge is limited and I'm still very new to ML as a whole.  If this was possible we could unlock greater RAW recording capabilities for pretty much all ML cameras.

I'm not into unicorn chasing, but by buying and inspecting/measuring/dissecting/identifying component elements/chips for a few fast SD PCBs one might be able to make more informed conclusions.

DV did say he liked to play with hardware ...

I do, but I'm not sure I'm in the financial position to risk breaking a $1K camera  :P and then I'd also need a $1.8K 7D2 to open up and tear down, unless someone can find the part sold by itself... And then what if the PCBs aren't the same physical form factor after all that?  What if the pins are different?  It's a looooong shot.

Feature Requests / Video crop mode: adjust crop factor?
January 05, 2015, 07:03:42 PM
Currently, crop mode is just limited to "on" and "off" and the only option is 3x crop.  Would it be at all possible to set custom crop factors, like 1.5x, 2.5x, etc?  If possible, I feel this would be a useful feature.

Feature Requests / Request: h264 GOP control in ML
January 05, 2015, 06:30:00 PM
Before bit rate control was merged from TL back into the unified ML branch, it was possible to adjust more individual parameters like slice and GOP.  Slice is now part of 'Qscale' but unfortunately the ability to change GOP has been removed.  It would be really nice if GOP control could be brought back in ML for at least the TL-supported cameras that originally had it, and possibly others as well.
