I've just tried the MlvApp and "tiff_clean script" command activated on mac and something weird happened every time the file was created:

When I export to any Prores, the .mov is created on the hdd. Then, the script runs automatically and a .tiff sequence is created. After the process is completed, the folder automatically deletes itself. Why's that? Anyone know?

In Premiere Pro CC the .dng from MLVApp needs a while to play and it's slower however .dng from MLVRaw Viewer plays smoothly.

Has anyone experienced this?

If I offended @masc in any way, I apologies.
Perhaps I overreacted because there's seem to be a trend these days: some users get really upset because some newbie dare to ask the "silly" and "obvious" question  that somehow goes against the forum rules and Google is always the way to go.

Both apps use different approaches of finding and eliminating bad/hot pixels and correcting vertical stripes.
I'll try that.

Which MLRawviewer do you use original old version without lossless MLV support or newer modified?

I used the MLVRaw Viewer 1.4.3 which is the last version. In Resolve, both .dng play smoothly.

Thank you.

TEST:

Two .dng sequences 14bits lossless, same raw settings.
.dng from MLVRaw Viewer 1.4.3 and .dng from MLVApp Alpha

 

 
In order to see the difference, I mixed the two waveforms. The red one represents the .dng from MLVRawViewer.  There is a slight visual difference between both. Doesn't seem like a big deal, however the MLVApp .dng visually has more red and blue.

In Premiere Pro CC the .dng from MLVApp needs a while to play and it's slower however .dng from MLVRaw Viewer plays smoothly.

I guess you know why. Let's have a look at what you have replied on the MLVApp thread:

Quote
uncompressed is uncompressed and lossless is lossless (compressed).

Oh, thank you very much for your very elaborate answer. Thank you for mentioning that uncompressed is uncompressed because I thought that uncompressed was, guess what... compressed.

I can't tell what MLVRawViewer does
If you can't tell, please don't answer. Do you a favor and don't waste your precious time.

Regarding my question:

Maybe MLVRawViewer just generates the .dng sequence way differently than MLVApp. Is there a visual difference? Guess what, I made a test and there is a subtle one on my waveform (Red and green channels are lifted 1 IRE). Why's that? I don't know, maybe is just my imagination. I'm not sure, that's why I asked the community. There's even a subtle difference between both compressed .dng sequences on the waveform and looks like the difference lays in the saturation (the .dng from MLVApp look more saturated). Or maybe both are the same quality, only they are interpreted differently.

Cheers.

Has anyone noticed any difference between .dng uncompressed and lossless?

Hi everyone,

I've just tried the MLVApp Alpha and then compared two .dng sequences in Resolve,  one exported from MLVApp, the other one exported with  MLVRaw Viewer 1.4.3.
I can't  see any visual differences not even after en extreme grade was applied. The MLVApp dng sequence doubles the size of the MLVRaw Viewer on my disc drive. I guess it is because MLVApp claims to export uncompressed .dng?

Any thoughts?

I've just done some tests with interesting results:

Canon 7D, Nightly.2017Dec07.7D203
Connected to my HDMI Monitor
Res: 1728x972
16x9
23.976fps
MLV Lite
No sound

Now comes the interesting part:

TEST1
Global Draw - On, All modes
Only Histogram Activated
Force HDMI-VGA - OFF
Clear Overlays - OFF

RESULT: Recording fails all the time (EDMAC timeout error).

TEST 2
Global Draw - On, All modes
Only Histogram Activated
Force HDMI-VGA - OFF
Clear Overlays - Recording

RESULT: Recording fails sometimes. However, if it successfully starts, it records continuously. No bad/corrupt frames. However, more test has to be done. No tearing.

TEST 3
Global Draw - OFF, All modes
Force HDMI-VGA - OFF
Clear Overlays - Recording

RESULT: No fails. Records continuously. No bad/corrupt frames. However, more test has to be done. No tearing. However, when I accidentally pressed the "ISO" button, the Canon menu showed up and the recording stopped. Conclusion: Looks like every time some kind of overlays are activated, recording fails. As you said, seems like  "ML might overload the memory bus when recording starts" and recording fails.

Hope this was helpful. Thanks again for your support.

The code is open source, feel free to modify it as you see fit.

One more question: the error only shows up on the screen at the begging of the recording. Once the recording successfully starts, It never shows up after. Why's that? Thank you.

That's because the regular mlv_rec does not attempt to detect this condition (so it doesn't print the error).

Bandwidth is the amount of data processed in some fixed amount of time. If you record at the same resolution, you get the same bandwidth (+/- some minor differences from slightly different file layout, unlikely to be relevant - on the image processing side, there are no differences in the amount of data processed).

Ok. Maybe it might sound like a stupid question, but I assume that there's no way to to "bypass" it?

Most likely, the bandwidth required for all these tasks is more than DIGIC 4 can handle.

If that happens at 24 FPS, I'm afraid there's not much you/we can do about it.

Thank you for your reply. I'm using it at 24fps (no sound). Isn't Mlv lite supposed to use less bandwidth because there's no sound, less metadata and no overlays? I'm telling you that because normal MLV Raw works just fine (however I get tearing when no force VGA is set).

Raw Video / Mlv lite EDMAC timeout
« on: February 13, 2018, 11:06:23 AM »
Hi everyone,

I'm using MLV Lite with an external monitor (no Force VGA is set, with clear all overlays set when recording)  and when I hit record, it stops pretty often. I get EDMAC timeout error. Does anyone know why?

I use Canon 7D with the last built.

Thank you.

How do you change the bit depth?

Raw Video / .dng - Blackmagic color space and gamma
« on: February 02, 2018, 06:23:59 PM »
Hi everyone,

In Davinci Resolve, on the camera RAW tab, you can set the BMD color space and gamma. However, the names are generic: Blackmagic Design Color Space and Blackmagic design Film Gamma.

Does anyone know which one the ML's .dng is based on? Because each one of the following cameras uses a slightly different BMD color spaces and gammas (correct me if I'm  wrong):

Black Magic Pocket
Black magic 2.5K
BMCC 4K
URSA Mini 4.6k

Sorry if this has been asked before.
Thank you.

Thank you for your answer. I have tried the Mlv lite for a couple of days and I can confirm that there's no tearing anymore on my 7D. Regarding sound, hope they implement it soon.

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.

Raw Video / Mlv Lite with sound
« on: December 13, 2017, 06:41:43 AM »
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.

Raw Video / No Tearing when Ext monitor connected
« on: December 12, 2017, 02:43:07 PM »
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.

General Help Q&A / Re: reinstall ML after format
« on: December 07, 2017, 04:40:18 PM »
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.
