I use the Bestview s7II monitor with ML 1.1.3 on my 5diii and it's been working well. (I'm still using ML's 5d 113 because I'm shooting lots of widescreen slo-mo footage using crop_rec)

The reason I like this monitor (1920x1200) is a nice build, bright enough for the money, ($190 on Amazon) and 7 programmable buttons. It has built-in zebras, false color, histogram, peak, audio levels, etc., and can also run off the included DC power! It accepts 4k input.

The Main Issues I've seen so far are these, which are still workable to use as a non-recording field monitor for the 5diii :

1) SOUND - If using the 5diii, TURN OFF the Bestview monitor's audio meters function that's built into the monitor* and use ML's meters display to monitor because the sound doesn't carry through the HDMI output from the 5d to the monitor via the cable - at least not in ML 113. Since I record sound externally, I pump it back into the line input on the 5d. You can easily set input levels on the 5d manually to match external recorder levels (I use Zoom h5 with shotgun or lavalier mics). This way you're recording a great reference/backup track to sync your external audio later.
*also you'll want to mute the monitor's sound if it is going through to the monitor from the camera to eliminate feedback

2) HISTOGRAM/ZEBRAS - My main struggle I'm trying to figure out is the difference in EXPOSURE histogram/zebra levels between ML and the monitor's built-in histogram when exposing via ETTR. The test footage I've recorded show ML as being correctly exposed to the right, whereas when I've set exposure using the monitor's built-in histogram/zebras for exposure, it records somewhere between 1-1/3 to 1-2/3 underexposed. I'm sure this is somehow due to the 5d's limited output from the HDMI that the monitor is reading to determine levels. Unfortunately I don't see anywhere to compensate to be able to use the monitor's built-in histogram or zebras.

3) FALSE COLOR - I prefer ML's false color over the built-in one. Bestview's whites and blacks come through both as different shades of magenta and I don't see anywhere to change the color scheme in the menu. ML shows a nice difference throughout the exposure spectrum, easier to read.

My preference is to skip the monitor's fun functions and to use all ML's display options which show through on the monitor because exposure all appears accurate after processing. (I use MLV app https://ilia3101.github.io/MLV-App/ and edit in Resolve).

Does anyone know if the "clean HDMI" output in ML's 5D v123 somehow addresses the inconsistency of exposure levels between ML and external monitors? Or could this possibly just be an issue with this particular monitor or setup?

Thanks, and I enjoy the reading!

ps. here's a quick peek at my 5d setup

That should be done from Canon menu, as FPS Override is not fully compatible with crop_rec at the time of writing. Refer to previous posts for details.

Thanks a1ex, yep I have the Canon menu set to 1280x720/60. I just didn't know if I should manually set the FPS override to 45p but it seems to be capturing 48p with a 2.35:1 ratio so that's awesome. I won't set any override.

I know you've heard it a million times but thank you!

Thanks theBilalFakhouri and JCut!

Have you tried MLV App ? same thing?

EDIT: I saw you have already lowered the resolution to 1920x818, so maybe it's about converting method, Try MLV App.

Switching to the MLV App did the trick. The footage converted just fine! I ran a load of tests today and I'm able to do pull 1920x1040 16:9 in 14bit lossless at 45fps just fine. I tried to do it at 48fps but only got 9 secs. However when I turned Global Draw off, I was able maintain continuous recording. (Also the 1920x818 works great at 48fps.)

Again, many thanks for your help. Sometimes it's the simple things.

One question - when forcing 45fps for 1920x1040, I can't select 1/130th shutter speed but can do 1/80 or 1/180. Which would you guys recommend?

Hi a1ex + ML geniuses, thank you for all your amazing work!

Wondering if you can shed some light on a buggaboo I'm having. All of my normal 1080p/24 RAW footage is great. I load the Raw video v2 (mlv_rec) for that and shoot 14bit lossless and it looks fantastic!

However, when I replicate your settings exactly for shooting 1920x818 48p for slow-mo, the footage just comes out with a black preview (or one broken image preview for all dngs) and unrecognizable as a dng for use after conversion (MLV Mystic, MLVFS, raw2dng, Mlrawviewer). Here are my settings:

-magiclantern-crop_rec_4k.2018Mar10.5D3113 (I've also tried 2018May1 build)
-5d Mark III firmware 1.1.3 (I've also tried v1.2.3 - no luck!)
-Modules: crop_rec, mlv_lite
-RAW Video: On, 1920x818, 2.35:1, 14 bit lossless ~50%, preview: Real-time, no Sound recording
  (says in green - 62.9MB/s, 120x2.2MB, 48.000p (50%). Continuous recording OK.)
-Crop Mode: 1080p45/1040p48 3x3
-Canon Menu: 1280x720 60fps ALL-I
-FPS override : OFF (automatically shows gray 48.000, Rs.83% which should be great)
-ISO: 100
-Shutter 1/130
-Global Draw: I've tried both On and Off, same result
-CF card for record: SanDisk Extreme Pro 128gb 160mb/s, SD card for firmware: SanDisk Extreme Pro 32gb, 95mb/s

I've tried every Data Format configuration. The only one that works has been 10 bit uncompressed.

Were you able to get 14bit Lossless to work, and if so, could you tell me what I'm missing? I've reloaded all the firmware exactly how it's supposed to be done, tried v.123 as well as v.113 (what I'm using now) and nothing seems to work, the footage is not in a supported format when converted to dng (I've narrowed it down to where it seems the original mlv's are corrupt in some way). When I switch to mlv_rec (v2) I am able to record usable footage so it doesn't seem to be the camera or the cards, but I don't get the same size options as using mlv_lite.

I'd love to be able to shoot RAW slo-mo at 1920x818 2.35:1 48fps if possible. I'd be grateful for any help!!

Thanks!   :)
