DLog video

[Tafflad]

I have and will be getting more drone footage which I am told is DLOG colour mode. (Logarithmic colour profile)

If this is the case I need to apply conversion (more than likely a preset LUTs)

How can I tell from Media Info if it is a DLog ?

The following sample is claimed to be pure unadulterated footage in DLog .... https://vimeo.com/1021301447

The Medai Info looks like

Doesn't Vimeo re-encode everything same as Youtube?
It's of no use.
Post a section cut from the actual drone footage

Also ProWo supplied some LUT here:

"Desktop\Air2SSamples\DJI_0029.MP4" - I think it's "D-Log M" instead of "D-Log" despite what you were told.

You can deduct it, if video is from DJI and it's not 709 nor HLG then it must be "D-Log M" or "D-Log".
It's not in mediainfo because it's non-standard color profile, anyway, they could write it in as a comment or something.

I don't see "unadulterated footage", to offer such you should have at least the Starter plan there.

OK .. sorry about Vimeo ...
Have now uploaded a 3sec clip here.

For me that is the issue how do I know which it is.

There's also a D-Log to Rec.709 LUT over at: https://www.dji.com/de/downloads/softwares/transcoding-mavic-3

By a drone model, or apply LUTs to see which looks correct, Avisynth+ example:

LWLibAvVideoSource("D:\DJI_002901.mp4")
ConvertBits(16)
ConvertToPlanarRGB()
Cube("D:\Whatever to Rec.709.cube")

D-Log M applied:


D-Log applied:

So there is nothing within the file information to show whether it is DLog-M, I had assumed there would be a parameter to show that.

Yeah.
