GH5 Game Over, Panasonic

It shouldn't be, not if it's raw. But is it? It's log encoded raw data, the dataset itself being described by metadata. All that needs to happen is a de-log transformation. Should be lossless. And if it were, then why the need for the other profiles?

I'm not stating anything, I'm asking the question, why are the other profiles needed? Why would they not just de-log into the rec709 or other profile? Is the profile even set in-camera or is this purely on the resolve end?

Tom, the other modes/profiles are metadata set in-camera when recording RAW. They are there for in camera preview and to speed/ease post work. DaVinci Resolve reads them and automatically applies them in the RAW panel without the need for a LUT node.

If you record ProRes, then they are baked-in.
 
The whole concept of BRAW is to allow non-destructive editing across various tools that can read BRAW metadata (using the toolkit) as described in the sidecar files.

This brings non-destructive video editing to the same level as non-destructive image editing.
Effectively Blackmagic has brought the non-destructive image editing as for instance shown in Adobe Lightroom for images to the video world.
 
CinemaDNGs were already that several years ago...they are basically photos/frames and I actually edited them in Lightroom! ha

Right, but CinemaDNG is not available in a video file, it's a collection of separate files with single images.

Nice! Thanks Joe!

Let's try for "less processed, less destructive video editing."

Agreed. I wouldn’t exactly call 12:1 compression non destructive. If it were there would be absolutely no point to 8:1, 5:1, 3:1 or 1:1 raw. There is no such thing as 12:1 lossless compression.

Also not 100% sure I would classify a baked in profile as destructive. Maybe destructive to the raw data but if somebody handed me uncompressed 10bit video that’s pretty darn non destructive as well. All depends on ones perspective and if they shoot video to have video or if they shoot video to massage the crap out of it and treat it like photography in motion.

Some of you should really take some of the BRAW clips and convert them to ProRes422 HQ to see just how little is actually lost. BRAW performance is impressive but it’s also not amazing to traditional video formats. BRAW samples play horribly on my 2012 iMac while 4k ProRes422 HQ edits insanely easily and plays back perfectly on the same machine. Yes it’s a pretty old machine but the point is the performance still greatly suffers compared to an almost visually equal format. ProRes raw also performs much better on this same machine so I think there is still a key advantage to ProRes raw. When one truly wants to treat raw as an alternative to other video formats one can multicam edit 9 streams of ProRes raw on a 2018 MBP. BRAW likely can’t do that although I have not heard of anybody actually testing it.

I think we now know why BMD created their own eGPU.
 
Non-destructive editing has nothing to do with the compression level of the source, it is about being able to make changes and record those in the metadata so that it can be undone or be interpreted by another tool.

Actually, CinemaDNG can be stuffed into an MXF file - along with audio, timecode and metadata in a single file.

When I first saw BM using cDNG, I was disappointed that they chose the image sequence format.
 
Tuesday 9/25 new GH5/S firmware announcement - should be something to it as it’s beint saved under wraps for a photokina presentation alongside the Panasonic FF cameras.

Hopefully not a new set of useless Picture Profiles, although I'd gladly take a (pseudo) RAW over HDMI profile! :)

The image sequence format is favored by many filmmakers. If the media is fast enough, it's pretty much bulletproof from any other corruption. You can literally rip the card out while filming and your footage will be fine because they are all individual frames that can be stitched together in any length to make a clip.

However, storage and transferring is cumbersome.

After using CinemaDNG, I came to the same realization. There's something very "film-like" about every individual frame being an independent entity.

So I've come a full 180, and then BMD chooses the single file format for BRAW.

UGH!!
 
Recording unique, individual *frames* is film-like and useful. Recording each individual frame as an individual *file* is a PITA.
