MLP - Mac OSX batch processing workflow (former cr2hdr-r)

No problem.

Off to bed.

*EDIT*

Here's the comparison after the latest update regarding Dual-ISO MLV's spitting out .mov's OE... it's a little better. I wonder if it's because I didn't maximize the ETTR effect properly in my 5D3 which may be the reason why it looks like that? No?

Those are good files to work with creating a good flat look on dual iso movie files to ProRes. Keep them and we try transoding when I got some flat luts going on.
Thanks

[DeafEyeJedi]

Sounds good.

Just let me know if you need the original Dual-ISO MLV's (or DNG's) for you to work with personally?

Not sure if that would help with the mathematics on your end?

[DeafEyeJedi]

Just a thought... What do you think of adjusting the OE to +18 (or +20 if you prefer) with HL toned down to -20ish (or more) along with a little contrast (+8ish) or whatever you like?

Would that help with the noise from being somewhat too obvious regarding the .mov ProRes files from Dual-ISO MLV's?

[Danne]

I think a lut is the way to start. I tried fiddling with gamma in dcraw but it lacks contrast and efficient highlight recovery. Got some progress with gamma changes in ffmpeg but the settings applied are still very insufficient.

[Danne]

you could try dcraw yourself actually. Open up terminal And write

dcraw
enter

check the alternatives to apply.

You can apply changes and convert a dng to a tiff file to see. In terminal write

example
dcraw -T -b 20 drag dng file here
enter

This will give you a brigthened (-b 20) tiff (-T) file. Tried highlight rcovery but leveling dual iso file was to hard to achieve.

Your not gonna get that much DR into a 10bit container (ProRes etc) without a log transform. A gamma function is not sufficient and you need to map the linear code values to log to be able to invert properly. I'm on it

I'm thinking this will be a job for Log-C or Slog3. I don't think Cineon is enough but I'll find out.

[Danne]

Awesome Andy . All input regarding this is most welcome.

[DeafEyeJedi]

Great inputs, @Andy600!

Looking forward to the progress...

Thanks, D for that. I'll definitely try it out myself since I don't mind fiddling with Terminal when timing persist. lol

*Feedbacks*

Just wanted to give a heads up regarding ProRes .mov's -- seems the Audio is corrupted in varieties of ways. I wonder if it's because of how I had to combined 5 CF cards filled with a bunch of RAW/MLV's, Dual-ISO, HDR, etc all together which included files with same names such as "mlv_rec.tmp" would have some kind of a negativity effect or perhaps confusion to your app?



Noticed that these files are still sitting in the PRORES folder after the app is done... is this normal or no?

Let me know what's the best way to show you some of the ProRes .mov's other than Vimeo?

[Danne]

Thanks fr feedback. Seems it converts and separates processes at the moment.
Will look into the tmp. Think it,s from the mlv files but those shouldn,t have to do with audio.

Have to look further regarding audio. You could test some audio files and see if you could narrow down anything.
Thanks

[Danne]

Are those mlv_rec tmp files not coming from your card which are created when recording MLV?

[DeafEyeJedi]

well when I go down to bottom of the DNG folder next to the last .dng file where you can locate the actual audio file (.wav) which playbacks fine in previews or iTunes.

But when playing the ProRes .mov file itself... it sounds like the audio would be chopping in and out (or sometimes speeds up and finishes it before the footage ends) since you say it shouldn't have anything to do with the mlv_rec.tmp files being combined which automatically changes the name to ".copy" and ".copy 2" you know that, right?

Are those mlv_rec tmp files not coming from your card which are created when recording MLV?

Yes, they were dragged over directly from all the CF cards. I still have them with the original footage unformatted if that helps?

I was just unsure whether it was a good idea when I combined 260 worth of RAW/MLV all together because 3 out of the 5 cards had mlv_re.tmp files (If I can recall correctly) and was prompted to 'replace files or keep all' which I knew I had to keep all otherwise I could lose Audio though I'll double check if need to.

[Danne]

Are there sync issues?
The audio is chopped of in the end but just a few frames. This is to fit with resolve. I could however skip that part when creating PRORES files. Either I let the file continue the extra frames which will let the file be alittle too long in the end or I can have ffmpeg cut the audio to fit the shorter movie file. Can you upload some examples ProRes for me to check?
The rec_tmp file I don,t think would be needed for audio with the files.

[DeafEyeJedi]

I'm not quite sure yet actually but sure let me pick a few MLV ProRes .mov's for me to upload into Vimeo overnight and have it to you by tomorrow.

*more feedbacks*



Guess it wouldn't spit out .mov's for MLV with spanned files?

I'll try it again overnight as well.

THanks, D!

[Danne]

It supposed to take spanned files and create a mov with those dng files. Not working?
You could dopbox some prores examples? I,d like to inspect the audio issues.

[DeafEyeJedi]

Sure if it doesn't take too long?

[Danne]

Should be fine. Have a good broadband connection here. Did you get the spanned mlv files to create a .mov files or was that a problem?
Thanks for help

[DeafEyeJedi]

Sounds fine now all of a sudden? Strange. I guess it was because I was looking through .mov's and playing them in Previews while your app was running in the background which could have cause the choppy playback with the audio?

Here I uploaded a few ProRes from MLV's... good thing we both have decent broadband connections!

Let me know if you rather have me not post this link on this thread for others to see? If so, please delete this post!

Goodnight, D!

Sorry couldn't sleep on this one! 

Regarding MLV spanned files after 2nd & 3rd  attempts...





Obviously the ProRes .mov just stops producing because the app won't pick up the rest from spanned files?

[Danne]

Thanks. Will check

[Danne]

Think I found the bug. Too long argument. Will try to fix tonight or tomorrow.

[DeafEyeJedi]

In response to your latest update from this AM regarding long spanned files.

Seems to work well for a MLV with over 7k DNG's and spanned files are placed in their original folder respectively.

[Danne]

Thanks. Problem is when trying to create a ProRes file from PRORES folder

[DeafEyeJedi]

Ah sorry thought I was doing it in the proper way of placing the MLV's in the PRORES folder to spit out .mov's, right? 

Also tried again with the non-cr2hdr-r_Long (just cr2hdr-r 2.1) and still wouldn't produced spanned MLV's (over 6k dng's) as expected per your suggestion...

I know you mentioned that you will be working on a fix sometime this week or whenever's convenient for you.

MLRV spits out ProRes 4444 HQ just fine but Audio seems to run shorter than the footage itself by several seconds towards the end.

Hopefully that won't be the issue with your next update! 

Thanks!
