Raw Video Postprocessing / Repairing damaged MLV files?
« on: August 30, 2015, 05:53:37 PM »
Okay so, I shot some RAW footage which came out really nice, and I previewed them in MLRaw Viewer, and stupidly forgot to upload them, and deleted the file. Aaaargh!

Since that time, I also removed my version of the Nightly build and replaced my friends version before realising what I'd done.

now, after some trial and error I have finally found ONE program, iCare Data Recovery that appears to have recovered the files, however despite the file size being right, they won't load into either ML Raw Viewer or RAW2CDNG.

Here's a screenshot of what they look like in my folder:

If anyone has any advice as to how these files might be repaired or recovered I would love to know

Raw Video Postprocessing / How far can one zoom in Premiere with ML RAW?
« on: August 21, 2015, 04:01:19 AM »
Hello!

Good to be back. ML Raw and Cinelog has worked out really well for me, and I'll certainly use it again, most likely when I come to do pick ups for my feature.

One question -

How far would you go with zooming on a quick shot?

Most of my film I shot on Canon C300 and I've zoomed in regularly to 130%, even 140% at times.

With the extra data in ML RAW, could I go to, say 160%?

I know the obvious answer is 'see how it looks', but I can't tell how it'll look on a festival/cinema screen.

Any opinions? It's one 3 second shot...

Just wanted to say thanks to Andy and also to highly recommend this to anyone considering it. It's worked a treat for me, and I am not even a DOP.

I'll provide a link to my film when done and you guys can see if you can tell which shots are ML RAW and which are C300!

TT

@Dubzeeebass I don't mean with LUT's either. (I think) I mean when trying to match the output with OpenColourIO from After Effects.

For example, I'm trying to match my 5DMKIII footage with Canon C300 footage, and to do that I'm using Cinelog and OpencolourIO.

The LUT I am using is Film Convert and that comes later.

@DeafEyeJedi

Hey man. Hmm well given my current experience and recent tests I'd actually say that Neat Video does a better job with certain techniques. I wouldn't say I'm fully qualified to answer that question with any conviction, but that's the way it's looking to me at the moment....

6
Ah yes. I saw that setting. Wasn't sure whether or not to use.  I can't find any tutorials anywhere on the latest version. I got some better results on the most recent version I did. I don't know if I actually tried that setting yet...

7
Better now I think. And a better colour match for the C300 footage. I found Neat Video worked better than ACR.

Not perfect but usable.

I think?

@Andy - have managed to get a good match for my 5DMKIII to the C300 footage so thanks a lot and thanks to everyone else who helped me with this as well as the noise issues.


@Dubzeeebass I'm not really qualified to answer this but if you're a Cinelog owner I'd say it's somewhere in your input and output settings in OpencolourIO...

God, just looking at the last link I posted. It's worse than the first. That's what happens when you stare at a screen all day without a break hah!

@DeafEyeJedi @Andy

Hey!

Do you guys mean Cinelog Rec709 in OpencolourIO? I'm guessing you do. At the moment my output in OpenColourIO is set to Cinelog-C.

Not sure if it's that or an LUT you're talking about. I'm using Film Convert for the LUT as far as I know. Having said that I do see there's a bank of LUTs with my download from the Cinelog Website so I'll certainly have a look.

@Andy if it's the OpenColourIO setting you're referring to, I could try it with the Film Convert SRBG setting, but ultimately it has to match the footage with the C300 I have. The setting in Film Convert I'mnusing for that is FJH160s Pro. Maybe I could adjust the colours if the tones match.

Re: Noise, I'm not much of an expert at noise removal with either program when it comes to video. In photography I tend to get exposure right, but when I don't I use Noise Ninja. Sometimes ACR is good for colour noise I have noticed when shooting weddings, but I only really know the most basic of settings and in photography have only ever pushed the luminance to 20 or so. Neat Video is a bit over my head tbh. But like most things, if you have the will to learn you will learn.

I had another go, I'll leave a link. No worries if you can't be bothered to download lol. I've been on this one clip all day. I've managed to get it a little cleaner but the blacks look like they could come down a bit. The thing is, if I put more than one or two effects on in Premiere I get a hideous banding effect around the car headlight flare and other places that doesn't go away with rendering or exporting.

I know from photography that editing colour heavily in anything under 16 bit causes a lot of that sort of thing, so I'm guessing this is the case in Premiere, and I need to guess the black point in ACR before AE. Here's my progress anyway:

https://www.sendspace.com/file/o9q5c3

These are the settings I used in ACR:



I have no idea if it's best, but I decided to favour less noise over sharpness, and didn't sharpen at all, but pushed the clarity to +60. Next go round I'll try and get it like this but adjust the blacks in ACR as I import to AE. It takes about 20 mins to render and export this clip each time lol.

Once again, thankyou for your help guys. I literally have no one else to help me on this and I've been through hell to get where I am with this film. At least I know how to shoot and edit 5D RAW now! (nearly)  ;)





12
Interestingly (for me anyway :P) when I switch to Cinelog C Rec709 output in Open ColourIO in AE much of the noise disappears. I know a lot of that is because the contrast is higher, but it really looks much cleaner too. (And to my eyes it actually looks pretty similar to how it does when I have the Film Convert LUT on with some colour differences) Wondering if I can export that way, but guessing not.

In ACR I have decided to import again with no sharpening at all but just increase to clarity. Maybe it'll be a bit cleaner now.

Sorry if I am boring you all with this. I have been working on this film for nearly a year and it is destroying me lol.  :'(

Nice to see this thread has sparked off something that might be of use to someone else :)

This is as good as I've managed with ACR, a Film Convert LUT and a touch of Neat Video. Added some grain back in with Film Convert - seemed to make it look less plastic... Not sure if the level of noise is acceptable or not? Feel free to take a look anyone. Oh, and yes I didn't have a focus puller or DP, so I did it by hand on the lens, just guessing. Not ideal, I know. The rest of the shoot was done very professionally lol.

https://www.sendspace.com/file/drxb54

Oddly, the footage appeared sped up when I imported it so I slowed it 80% and it seems better. Project frame rate was set to 30 fps and I shot at 25, so I thought it was the reason, but it turns out even after switching to 25 it still looked to fast. I'm not sure if I was imagining it or not. He just seemed to waddle into the shot too fast...

EDIT: Might try again with no sharpening at all in ACR before AE






14
lol ok yeah I thought it may have been overkill!

Would be interested to see the link. Will try and get my head around what you're saying RE: CTRL ALT etc but it's a wee bit over my head. But dedication's what you need etc.

With regard to the waffle, that's why I'm here! Go for it! :)

15
Hey thanks Andy! Exciting stuff!

Look forward to hearing more!

I'm understanding the essence of a lot of what you're saying but I won't deny a lot of of it is going over my head.

I've ony ever used ACR noise reduction with the most basic settings as I am much more used to using Noise Ninja for photography, but I found this tutorial:


Long story short, the settings look like this:



He also turns the clarity up a touch.

I've brought it into Premiere and once the same Film Comvert LUT is applied it's not a bad match, although it may be a wee bit too sharp in the end. I might bring the sharpening down a tad on the next attempt which should help with the noise.

Glad I at least got it right about the Cinema Gamut and the C500, and using DNxHD 444 :)

Cheers!


16
Awesome chaps. DNxHD 444 it is then. I tried google but couldn't find anything.

Winning! :)

17
Actually yeah he did mention something about ettr to me in an email. Unfortunately I'm no DP and I had a ton of things to worry about such as sucker mounts and lights etc. I did my best, but I didn't manage to use colour charts or ettr. I guess ettr would have been the way to do it as you suggest.

I know it's off topic but on a side note while I seem to have someone's attention you don't happen to know my best export settings in AE? I'm on PC and have tried DNxHD 444. Guessing this is best although I see there is DNxHD 185....

Thanks. It's all I need to know now I think.....


18
Hey Danne. Thanks! Yeah, when I'm photographing weddings etc I usually expose to the right a little then bring it down a half stop or so and a lot of the noise disappears. What I didn't factor into this equation I think was that C-Log lifts all the shadows. What looked right on the monitor wasn't going to be how it looked in C-Log! Guess there's a way of monitoring for this. Haven't sussed that bit out yet!


19
Yeah, after some ACR noise reduction and the Film Convert LUT it looks better. Was shocked at the level of noise though. Like I said, I was only shooting at iso 1000, let alone 1600 or 3200.

Looks better now: (Doesn't look this noisy when watching actual video footage and is converted to jpeg in the upload):

Talk to me. Russian Fireplaces?

21
Ok so the first thing I notice upon viewing my first 5D RAW footage is that it's noisy as hell. I gather that this is due to the incamera noise reduction not being used.

As a photographer, my experience is that the ACR noise reduction is excellent. I don't have a lot of experience with Neat Video, but I'm told it's also very handy.

Does anyone have any advice, or a workflow that suits them?

Wondering if a mixture of both might be good, ie a gentle ACR noise red followed by more specific treatment with neat Video.

Thoughts?

EDIT:

Here's a pic that illustrates what I'm talking about. Some pretty savage vertical kind of banding noise. (I'm still not entirely sure if I used the correct render output in OpencolourIO and AE. In OpenColourIO I used Cinelog-C, and in AE the output render was at DNxHD444.

The noise can be removed I'm sure. Plus the contrast will be a lot different after adding an LUT.

If you scroll across to the right on the image you can see the vertical lines...

F2, iso 1000....

EDIT: Does the way you export from RAW2CDNG make any difference? I exported 16bit maximized. It's just that the footage seems unusually noisy for iso 1000....

Raw Video Postprocessing / Re: SlimRaw – CDNG compression tool
« on: June 18, 2015, 02:33:55 PM »
Looks seriously handy if you're making a feature and are dealing with massive amounts of data...

23
Hi chaps.

Last night I got footage into Premiere and it matches pretty closely.

Can anyone just confirm to me that on PC the best output render for me when trying to match C300 C-Log with my 5DMKIII would be Avid DNxHD 444? I'm assuming it's either this or Avid DNxHD 185.

Also, with my 5D is the OpenColourIO output Cinelog-C?  Pretty sure DeafEyeJedi has confirmed this,  just double checking.

It's the former question I am most unsure about. The match is pretty good,  I just need to mess with the Three Way Colour Converter a little to get it spot on.

If these two things are correct,  I am basically ready to rock and roll!

Anyone? XxX

24
Hey! @DeafEyeJedi..yes exactly...nail on head. I was missing the codec!

It seems I may have sussed it in the mean time and I got the Avid DNxHD codec and went for DNxHD 444 (see my multiple edits at the top of my previous post lol)

Not sure if that's the right one though? But I think 444 is supposed to give the most faithful colour rendition?

As for the output setting, it seems that the C500 is the only Canon camera that supports Canon C-Log Cinema Gamut anyway, so Cinelog-C it must be, and it looks much better at that setting. In fact I bet I can even pull it down a half a stop.....

Thanks mate. I reeeeeeally appreciate your help! I've been sitting in front of this computer now for about 16 hours today (and about 200 hours in the last week or two) and I'm finally getting an idea of where to go with this!

As a photographer/director I had never even shot video two weeks ago, let alone in ML RAW. Now I can shoot it and edit it!

I haven't looked at the link you just posted, but that's next, cheers!

God blesh the internet

Thanks DeafEyeJedi.

What should I call you for short?

I've responded with thanks and another question. Fancy a look? I'm not sure how to hotlink it here.

I can copy and paste if you like!

Andy, sorry for badgering you so much. I really think I'm almost there though, and thanks for all your help! :)
