I have a Toshiba 64GB EXCERIA 1000x CF card and just bought the 128gb version of the same model. I've had the 64gb model for a while and has worked flawlessly but the newly acquired 128gb card is not recognized by my 7D every time I try install magiclantern with it. 128gb CF cards not doable with magic lantern with my 7D? What am I doing wrong? Please help. Thanks.

Cool. I speak Spanish so I also understood the doc. I would recommend you start your doc way sooner, your intro is almost 2 mins long for a video that is almost 7 minutes long. In other words, a 1/3 of your video viewing time is wasted on the intro, two minutes of intro is cool in a 2-hour film but not a 7 min. short. If your in love with the images and sound of the intro then I'd suggest you put some voice-over from your subject explaining things earlier in the beginning.

Raw Video / Re: Problem with playing back whole raw card
November 09, 2017, 11:14:26 PM
When this happens to me I just copy the MLV file to another hard drive (which I need to do anyways to back up) and that lets me play the MLV file via Mlviewer. I freaked out the first time this happened to me... haha.

I agree with Walter Schulz, I work at a university where we check out a/v equipment and people using micro SD cards with SD adapters have always had issues shooting video with our Canon T3i and T5i DSLR cameras with their regular, native, h.264 video codecs and ML is way more demanding. Just get the proper fast CF cards they work like a charm for my 7D shooting MLV RAW video.
#5
Figured out the solution and it was quite easy.

After converting my MLV video files to DNG files all I need to do is fine the one DNG file I want to convert into a photo by highlighting it, right clicking it open with the "Open with" option to choose Adobe Photoshop, this automatically opens it in Adobe Photoshop's Camera RAW to color grade and correct. Then with Photoshop turn into a jpeg. It works super well! Love that I can make photos out of my RAW video stills. Its like taking photos and shooting video at the same. This was super convenient for my lil sis's wedding. Another reason to love ML and its MLV feature!

What's the easiest way to convert MLV video files to CR2 photo files to color correct and grade in Adobe Camera RAW and finally make into jpeg photo files or convert DNG to CR2 for the same reason? I think I now how to change DNG's to jpegs but I'd rather work with RAW photo files first. Thanks.

Cool. But did the 10bit let you record longer takes or at larger resolutions and if so, how much more compared to 12 or 14bit?
#8
This has never happened to me with the mlrawviewer app; which I love, but recently when I renamed some MLV files I shot with my 7D and converted them to DNG files about 30 seconds of time was cut off at the end of each clip. But when if I convert my MLV files without renaming them into DNG files they are fine and the last 30 seconds of the clip remain. Anyone know why this is happening now and how to fix it? I'd like my MLV and DNG files to be named the same to archive and keep track of them a lot easier.
#9
Are these current updates and stats for the 100D true? And if so, could we expect some cool improvements to the 7D also? Don't get me wrong I love my 7D+ML RAW video combo but so far, its been the 5Diii and now the 100D which have added improvements lately but nothing for the 7D.

Thanks!

What is the default bit setting for shooting MLV video is is 12 or 10 bits and how do I change it?
#11
Just wanted to give a quick thank you to this group, I love this app and everything involved with ML. You guys rock to do all this and for free, you guys are a cinematic godsend. Thank you.
#12
Like it. Simple but elegant and very nice images and slider work. Not over top either but very effective.

General Chat / Re: Extrem ISO Noise
March 17, 2017, 06:48:19 PM
Adding to what Levas said, this technique is called ETTR, Exposing To The Right and using ML's ETTR tool (RAW Histogram) makes using this technique much easier. You use the ETTR tool by pointing your camera on the subject or area you want to measure exposure and then adjust your iris (a variable ND filter is also really useful for this when you do not have de-clicked iris cinematic lenses) until the ETTR tool reads EV 0.0, now you have a correct balanced exposure, but now you open up the iris (or variable ND filter) by one f stop so it now reads -1.0 EV, you are now over exposing the image by one 1 f stop. Now in post you re-adjust the exposure by lowering it and or using curves to adjust. This works for my 7D so well that I currently shot a significant part of my short film at 1600 ISO because I had a crappy light kit that I borrowed and I did not get noise but rather a really clean picture and my 7D is notorious for bad noise at 1600 ISO.
#14
Ooooh. Thanks. By the way, how do you guys shoot in crop mode if your moving the camera around its gotta be super hard to frame your subject with so little of the actual image is seen in the camera's LCD screen? Is there a way to shoot in crop mode in camera but the video output to an external monitor would look regular, i.e. non-cropped?
#15
ted ramasola, what do you mean by "Even higher than 1780X817 is 1856x1044  16:9 @23.976fps. Its continuous." Do you mean because the 16:9 aspect ratio covers more of the sensor's pixels at the bottom and top of screen as compared to a wider aspect ratio like 2:39:1? Or are you talking about a way where you are using more physical surface of the camera sensor, that's closer to real 1080p? And if this is the case, how do you do that and can it work for shooting with the 2:39:1 aspect ratio? 
#16
Im sorry crop mode has been around for ML for a while now, right? So what's the big deal with this new update?

DeafEyeJedi, what do you mean by "Indeed the good ole' 7D is still rockin' and currently more than ever w 10/12-bits (still in experimental mode)"? What do you mean by 10/12-bits?

Basic canon prime lenses are great and affordable:

These two lenses you will probably use 90% of the time:

Canon EF-S (APS-C) 24mm f2.8 Prime Wide Angle lens $120 - 150
https://www.amazon.com/Canon-EF-S-24mm-2-8-Lens/dp/B00NI3BZ5K/ref=sr_1_2?ie=UTF8&qid=1485813235&sr=8-2&keywords=ef-s+24mm
This lens is amazing because it is prime wide angle lens made specifically for APS-C sensor size cameras that costs $120-150 with a decent f stop 2,8! Super rare APS-C wide angle lens with super rare low price. Must have! Most wide angle lenses with an f2.8 will cost $300 and above and good luck finding one made for an APS-C sensor size.

Canon EF 50mm (80mm full-frame equivalent) f1.8 lens $100-120
https://www.amazon.com/Canon-50mm-1-8-STM-Lens/dp/B00X8MRBCW/ref=sr_1_3?s=electronics&ie=UTF8&qid=1485813743&sr=1-3&keywords=canon+ef+50mm
50mm is a must have for basic prime lenses especially with an f-stop of 1.8 for great boké (blurry background) and low-light performance.

Very beautiful images! You really know how to get the most out of your 7D with MLV RAW! I too have a 7D using MLV and shooting a short film and am surprised there aren't more people investing in one of these instead of BMPCC which is about half the cost and close to the quality of it especially if you know how to shoot with it.

a1ex @ "The exact meaning of 0.0 is given by the options you have set in ETTR submenu. It can range from very underexposed to severely clipped, depending on your settings and your subject." Cool but does that mean that the default settings in ML's ETTR the value of 0.0 EV is already ETTR with a little wiggle room for safety? This according to the last URL you posted which has four photos of a white flower, first two using Canon's meter and the last two using ML's ETTR. As mentioned, I think this might be true because I have been shooting my scenes at -1.0 EV and the images did not look overexposed. I also imagine since my 7D's dynamic range is only 11.7 stops it would make sense that I could only over expose one stop anyways unlike the BMPPC that has 13 stops of DR and probably could get away with even overexposing 2 stops to do ETTR... not that I would do that, just saying if that happened by accident the image would still be recoverable in post with curves. Right?
#21
@ DeafEyeJedi, this also pertains to the 70D? This guy on this youtube video says he can only get about 6-9 seconds of RAW video recording (close to 1080p) with his 70D and he even shows a chart that shows resolution vs time record times.

https://www.youtube.com/watch?v=z3kStLheFxE
#22
What is the RAW video recording time limit with the 70D because of its buffer size? With my 7D its the 4G limit which is way enough time to record a film scene with. But I know that most Canon models can only record about 10-15 seconds of continuous RAW video, does the 70D also have this time limit issue?
#23
Thanks for all the responses but I pretty much knew most of the things I was told on here. FYI, I have been using the ETTR tool for shooting video and I do usually over expose by -1.0 EV and so far the images I've gotten are good. I might starting knocking it down to -0.5 EV to be more of the safe side. My confusion comes from the values of 0.0 EV on the ETTR tool. In other words, when it does read 0.0 EV that means it is already overexposed to the right and now its a matter of how many more stops to push it? Or does 0.0 EV read as an already properly exposed image and now I need to start opening the iris more to do ETTR?
#24
I need clarification on how to use the ETTR tool with the RAW Histogram on ML when shooting video. When the ETTR tool reads EV 0.0 that's a perfect exposure being read by the ETTR tool, correct? But if I really want to do ETTR I should then open the camera iris for it to read a negative value correct, like EV -1.0 that way in post I can lower the exposure, etc. to get a better image with more data, correct?

Camera-specific Development / Re: Canon 7D Mark I
December 16, 2016, 06:52:41 PM
There are only a handful of Canon models that can take almost full advantage of ML's features and the 7D is one of them, the others are the 5DII and III but the 7D is 1/4 the cost of a 5DIII but its almost as good as the 5D's though the 5D's have a full frame sensor as apposed to the 7D's smaller APC-S sensor. But, the 7D's APS-C sensor is close to the size of a Super-35mm digital cinema sensor! The rest of the cameras like the 700D/T5i for example can only record RAW video for about 10-15 seconds and not close to the maximum resolution of 1080p. The 7D can record RAW video til the CF card is full and close to 1080p resolution. But RAW video is so sharp and your taking better advantage of the camera's dynamic range that when you scale it to 1080p it still looks sharper and better than the 7D's native video h.264 codec.
