Any thoughts?

["by the crop_rec_4k branch"]

That part talks about some build and I think only three cameras are supported "by the crop_rec_4k branch" (whatever that means).
So, yes I did read the whole thread. Have you read mine? However, I don't have the technical knowledge to understand that. That's why I said: "People talking about sound", I don't understand that part. Actually I don't understand all the programming part. If my Topic bothers you, don't reply.

I guess mlv lite sound is just a work in progress.

I have read the whole thread. That's why I'm asking. People talking about sound, however there's no sound. One user asking, nobody answers.

When it first come out, the sound wasn't available.

Hi everyone.

I've read somewhere people talking about Mlv Lite with sound.  Does Mlv Lite work with sound, because I don't get any wav files?

Thank you. 

[unless]

Hi everyone.

I've just tested the MLV Lite and there's no tearing on my 7D when it's connected to an external monitor. I always get tearing (when max. res. is set with AR to 16:9 and 23.976fps) unless I set the "Force HDMI-VGA option", I change the resolution or change the Aspect Ratio to 2.35, 2.20 (actually every AR that reduces the max. resolution).

That sound like good news. However I never tested the MLV Lite on the field and don't know what to expect.
I've read the forum, but there's only advanced technical information.

Any thoughts?

I got some issues:
Sometimes I get "EDMC timeout error" when hit Record and the camera is connceted to the external monitor. The only solution is to restart the camera.
No sound with MLV Lite

I have a Canon 7D 203. Latest Build: 2017-12-07 with a Monitor Lilliput.

Thank you.

I've just reinstalled ML and it seems to be working just fine. I had the doubt after I've formated my card in windows and not in camera.

Instructions are clear.

Thank you.

I know that. But, after I copy the nightlybuilt on the card, should I run Firmware update and that's it?

Hi there.

I've just formated my CF card (quick format on win, FAT32) with ML installed on it. I know I shouldn't do that.
Anyway, I want to reinstall it (the last nighbuilt) and I wonder what's the correct workflow?

I have a:
Canon 7D, v203
Windows 8

P.S: The link to download EOScard.exe is dead.
Thank you.

Thank you for your reply.

Perhaps I remove the cards too fast.

Best regards.

[pretty frequently]

Hi everybody.

I´ve been using ML for almost two years without any issues.
However, pretty frequently, by switching the CF cards, the camera just refuses to power on. No error, no CF light, nothing.
The only solution is to take the battery out, wait some seconds and then insert the battery back. It happens on my two Canon 7d with the same firmware.

Has anyone experienced this?

Best regards.

Thank you very much  for your time and support.
Best.

It worked!!!

The problem was that on this thread http://www.magiclantern.fm/forum/index.php?topic=7122.0
there are two links to download the mlv_dump:


BAD VERSION where it says WIN ONLY (didn´t worked for me): mlv_dump: most recent nightly download page. (binary for WINDOWS only)

GOOD VERSION: mlv_dump: or here (binaries for WINDOWS, LINUX and OSX)

I´ve tried the second  one and it worked. I don´t know why, perhaps the two .exe are different. So frustrating.

Thank you.

How did you do it?

My workflow is (on Win):

1.  I copy the mlv_dump.exe on the same folder as the mlv file
2. I run ¨cmd¨ to open the command window
3. Go to the mlv file location (e.g. C:\Folder>)
4. I run the c:\Folder>mlv_dump --black-fix=2048 -o b.mlv m01-1526.mlv

That´s  the  message I get after, however the new mlv looks the same:

Mode of operation:
   - Input MLV file: 'm01-1526.mlv'
   - Setting black level to 2048
   - Rewrite MLV
   - Output into 'b.mlv'
File m01-1526.mlv opened
File m01-1526.m00 not existing.

Hi there.

I´ve just upload a mlv  file   ( 134MB - that´s the smallest one I  have) with the wrong  black levels.

You can download it here:

https://expirebox.com/download/f56643f020df06a01ae63f07756d9f43.html

As I said, I´m not able to change the black level with mlv_dump anymore, no matter what value I put. A new mlv is created, no errors, just that the new mlv looks exactly the same.  It never happened to me before.

Thank you. 

Hi everyone.

For some reason, changing the black level with mlv_dump doesn´t work anymore. It did work before.



I always used this command as in the thread http://www.magiclantern.fm/forum/index.php?topic=11664.0:
mlv_dump --black-fix=2048 -o out.mlv in.mlv

It creates a new mlv, but with no changes at all. It drives me crazy....

If I export to .dng (Raw2cdng) and I use the exiftool command -BlackLevel=2048 input.dng , I get the ¨0 images updated¨ message. Someone knows why?

Here you can download a .dng file:

Is there  way to fix this?

I´m on a Windows 8.1 machine.
Thank you.

Hi there.

At 00:10 looks like moire (on the garage's door). Looking at the .dng, I'm not seeing noise, but let me put my glasses on... 

Cheers.

Check this thread (external monitor for 5d3):

http://www.magiclantern.fm/forum/index.php?topic=14652.0

I personally use 2 cheap monitors (connected to each other) from Lilliput, which are great for and focusing on my 7D.

This thread from 2013 talk about usb 3.0 readers vs usb 2.0

Hi there.

1. A lot of people recommend Komputerbay. Some say are the best cards for the price. Maybe they're wrong. I use 32GB 1066x Lexar cards for my 7D and no problem. Yours is a 5D3 and since I don't want to compare apples and oranges, you can find a bunch of topics here: http://www.magiclantern.fm/forum/index.php?board=40.0

2. Yes, expose to the right. I highly recommend it even though some people say, you don't have to. However, be careful, sometimes it gets very tricky. I've done tons of tests (most of people have done none) and for my 7D I can overexposed 1-2 stops in most situation without clipping the highlights. Always use the Zone System and common sense. 

Read this .pdf (3 pages), very informative :http://www.adobe.com/digitalimag/pdfs/linear_gamma.pdf
If you're lazy, watch this video: https://www.youtube.com/watch?v=4P5Fjxit4GM

3. I'll let the final question to be answered by someone with more experience in the field using ML. You get sound by shooting .MLV (not blockbuster film quality). I always shoot sound separately and sync in post.

Hi Nelson.

You got some nasty moire shots on your 700D. My shots never suffered for such an extreme moire on the 7D.  I've been using the same technique as you did (blurring the UV). Searching the forum/internet for a long time, couldn't find a better solution to remove it. Looks like blurring the color channels is the only trick available.

Have you tried using MLVRaw viewer instead of MlVProducer?

Best.
 

Thank you guys for your replies.
I haven't tried the MLVFS yet.
MLVProducer looked promising, I've done some tests but without success. Perhaps because it is still a beta version.
Regarding the mlv raw applications in general. For now, I'm only interested in converting the mlv files to dngs. I know that each one shares a lot in common and, at the same time suits different needs, but which one do you think is better? Why there are so many? Have you experienced any differences in the demosaicing algorithms that could affect the final quality using a specific application? Maybe I'm just asking a silly question.

Any thoughts?

Thank you for your reply Ansius.
My tests shows that ML in camera histogram is the same as on external monitor at least on my 7D with the Lilliput monitor. I've been taking notes of different shots, different exposures, etc. and I haven't noticed not even a slightly variation.

Hi there.

I've just bought two Lilliput 5D-II/O 7 " monitors and they work well with my 7D. Both come with hdmi in & out and you can connect them together (one for the camera op.,  and the other one for the director). If you press the 5D-II button on the monitor, you can actually preview the full image on the 7¨ screen (some ML overlays are slightly cropped).
The quality isn't astonishing, however it is better than I expected for focusing and framing. Now, I'm wondering how long this monitor will last, regarding the price vs. construction quality issue.
Some people say that ¨Histogram is not the same in camera vs. external monitor¨. That's not accurate on Lilliput 5D-II. You'll get the same histogram readings.

Best.

Hi everyone.

I wanted to share my tests about trying to remove the vertical stripes from my .mlv footage using different applications. I'm new to ML so please feel free to share your thoughts (maybe something wrong was done on my tests).

Canon 7D ML Nightly.2015Aug19.7D203, .mlv files. The blueish footage was shot with ISO 100. The cat's footage was shot using ISO 200. Both were overexposed in post, so the vertical stripes be more visible.

Here are the results:


1. MLRawViewer 1.4.3 with Stripe Correction On: It successfully removed the vertical stripes. However, there's some magenta in the shadows area (look at the 2nd image of the cat head below) 

2. Raw2cdng.1.6.5 with Vertical Banding ON: Failed to remove vertical stripes

3. raw2cdng.1.7.4 with Vertical Banding ON: Failed to remove vertical stripes

4. Mlv_dump with: Failed to remove vertical stripes

5. MLVMystic 0.5 (beta) with Vertical Stripes Fix 5D MIII: Failed to remove vertical stripes As the name says, perhaps works better only on 5D

In the image below you can compare the results of MLRawViewer 1.4.3 with Stripe Correction On & Off



Thank you.
