I think we are actually very close to having the changes merged into main nightlies so you can use your external monitor at full resolution (no more force vga) I have had very good results recording up to 1728x864 with full hdmi output and no tearing with the build I posted. Sadly, this isn't quite 16x9, it's 2:1, but a huge improvement over previous results (which exhibited tearing at EVERY resolution) so you will still have to use force vga for 1728x968, but I'm reading everyone's notes and digging through the code every day to try to get the same performance with full 1080i hdmi out, as is possible with force vga (480p output)

Something I noticed is that one of the most resource hungry features is the raw histogram, (it makes the cpu load jump from 27% to almost double, and drastically reduce raw performance. Leaving global draw on seems to be fine, as long as I turn the histogram off when I'm using my monitor at full-res.

Solving this tearing issue completely, remains the highest priority for me because the 7D is still the only Super 35mm (aps-c) sensor camera (ml supported) that records reference sound and has a fast CF card, and this will likely be true for a while, so I really feel that it's a good investment for me and anyone else who wants to use Canon DLSR for serious cinematography.

I would love to see some of your work. I too work in video production for a living, in a fast turnaround environment. I shot the entire season of "Let's Go Youngstown" on aps-c canons (t2i, t3i, 7D) which you can watch here if you are interested:

it's a television show that airs weekly on the CW in my city, it is broadcast in HD, and the IQ of these cameras is nothing short of amazing. Magic Lantern made it possible for me to leave my old boring job as a graphic designer and follow my dream to become a DP, and for that I am truly grateful!

Our intro for next season, and some of the segments will be shot in MLV RAW this year, and I'm really looking forward to sharing those with you after they air.


Well in that case, I'm a little bummed I missed out on the party to help test this out for yah! :) Eagerly looking forward to running it through the paces regardless of whether it appears in a nightly soon or if I use the build you posted previously. VGA out on the monitors isn't all that bad, and certainly sufferable IMO, but there's nothing like seeing a crisp HD image on the monitor. Even at 2:1, in a pinch a usable HD image is a good tradeoff for making sure my focus stays sharp when I'm wide open on a quick tracking shot. Appreciate all your hard work on this!

Also - appreciate the quick note on the histo - I had no idea it ran the CPU that hard, I'll be sure to keep that in mind next time I'm trying to keep my usage down.

Just checked out the link (and the whole site! :) you shared - great stuff, very solid edits, and nice color! I don't need to tell you this, but the color on any of the canons h264 image is just a pain to work with, so it's awesome to see folks that are able to push it far enough to achieve some really nice grades. (I know I never can, haha!)

IF you're interested, here's some of our stuff, a documentary we shot about a year ago, all on a 60D and a 7D with a gopro H2 for timelapses and the like:

And an (old and in need of update) reel, again, shot on our 7D and 60D:

Sadly, no RAW footage to share just yet aside from test shots of my long-suffering wife and kids, but hoping to have some online soon after another round of shooting out in North Carolina this week! I shall report back with an update for y'all. In the meantime, I'm happy to make myself useful for anything you folks may need, no idea how to code, but have lots of gear I've accrued over the years and more than happy to configure it in any form or fashion to run some tests for the good of the order! :)

Hi All,

Long time listener, first time caller. Just wanted to report some of my findings with y'all, that have very likely been touched on in other threads, but just to let y'all know. I'm running the 8-20 nightly on my 7D, with pretty good results. @dpjpandone - I've yet to DL and run some test shots with your build, but going to try and see I can do so once things slow down at work and I'll be sure to report back.

I finally gave up on the hope of using the RAW module for paid work after I kept having sporadic test shots with occasional corrupted pink frames, and the vertical lines issue also cropped up here and there. I've read that it's fixable with a little bit of coding and post, but with our workflow, we need to shoot, and be ready to deliver the following day, so no bueno for me.

For me, the working setup thus far has been using MLV, 1724x968 @ 23.976. I run a lilliput 663 on my glidecam, with a nyrius aeries pro sending video wirelessly to a marshall directors monitor. I shot a :30 a few days ago with these settings and every shot that came off the card looked great.

RE the HDMI out - I experience a lot of tearing when not using "Force VGA" option, which is why I'm itching to try dpjpandone's build. FWIW, I've also disabled global draw for good measure, which from my last batch of test shots didn't seem to have an effect either way. (wasn't using peaking or anything fancy, just histo and all the standard info like ISO, SS, aperture, etc.)

For me, initially, I had a ton of pink frames via RAW when i was doing my first tests on my sandisk extreme CFs, while I was waiting for my new card to arrive. I opted for this one, and have no complaints or issues thus far:

For post, I run it all through the paid version of RAWMagic (heresy, I know. :/) It does a quick job of cranking it all out though, and working with the DNGs in premiere for a rough edit with scratch audio is a lifesaver.

Lastly, wanted to give a big "Thank you" to all the devs that have made this possible. I have been hating my canons for the last year or so, and couldn't wait to upgrade to something better. With Magic Lantern I feel like I've got a whole new camera now. Really top-notch, and really appreciate all of you!
