ProRes RAW was one of the biggest announcements at NAB 2018. But what does it mean, and what can you do with it? Let's have a look at some actual ProRes RAW footage and see what it can do.

Fyi, I tested several dozen HDMI cables. The ones labeled "Monoprice 18gbs" all work. The Amazon basics "highspeed with ethernet" work. Between atomos and GH5 at 4k60.10bit.

Great demo here, Joseph. This is the best early ProRes Raw demo I've seen. Keep it up!

Thank you for doing this, there is a dearth of actual ProRes Raw tests out there.

However, I think the demonstration of highlight retention here is more than a bit misleading. Most recent Sony video cameras that shoot S-log have high noise in the shadows and some exposure leeway in the highlights – so everyone shoots S-log overexposed a stop or two REGARDLESS of recording codec (yes, the 8-bit codecs on the A7 line struggle with this method, but not really with highlight clipping, but more banding and color fidelity).

What's also misleading, is that you are viewing the Raw-to-S-log and then S-log-to-rec709 image as you grade. If you were viewing the s-log, it would be plain to see that the "overexposed" shots are correctly exposed for this camera system (or fairly close), while the two ladies in the park shot is actually underexposed. Those standard, automatic rec709 conversion LUT's in FCPX ALWAYS look awful when you have correctly exposed log footage of any kind. This has been my experience with C300 footage, Sony footage and Alexa footage.

The "amazing" highlight retention here is mostly a trick of how the footage was incorrectly displayed to begin with.

A real test of the capabilities of ProRes Raw would have to include the same shots/scenes shot in:

- The camera's native codec
- ProRes (either natively or through a recorder)
- ProRes RAW
- (A Raw-to-ProRes recording could also be informative)

And then you compare how the SAME camera sensor at the SAME settings watching the SAME thing retains dynamic range and color-fidelity with different acquisition formats.

The fact is that it can be very hard to see a difference between a ProRes 4444 recording and an Uncompressed ARRI-Raw recording – or so Roger Deakins found out in his testing. 10 or 12-bit LOG recording is a very powerful tool, and I think the ProRes Raw benefit over that is going to be very marginal in most cases.

I noticed prores hq capture from hdmi produces pixels in blacks that I remove with denoise in davanci resolve 15 studio. But h264 mpg is smoother in camera. Thanks for explaining this why noise appears in 440mbyte sec capture

It appears cameras don't record Raw because Red has a patent on compressed raw in Camera. Blackmagic does it in camera but is supposed to do some demosaicing in camera or other modified processing before compression.

Thanks for the video, great - as always.
YouTube Note: Maybe something my end, but. I didn't get a notification, my home page didn't offer your video immediately afterwards. Basically it got a very low profile. Thought I would mention it in case some settings were changed that have effected your visibility. I think your videos deserve many more views and sub's.

The Inspire 2 records to an SSD in order to do ProRes or RAW or ProRes RAW, but I guess you could call it internally, just not the the micro-SD card that is also on the Inspire2. I have been very happy with ProRes RAW, LT saves a lot of space compared to HQ but still more than regular ProRes 422. Great video and thank you for posting it.

Ha ha, I love the off-the-cuff honesty. Sometimes, it takes me a while before I understand something technical - and the market moves fast

I'm trying to work out whether Arri Alexa Mini format work on a Windows 10 machine with Avid Media Composer

It doesn't look very promising at the moment

Hi, thx a lot for this video :) Do u have any idea about denoise the ProRes Raw footage in FCPX? :)

*Is prores raw lossless in every compression ratio option?*

The rates thats ProRes Raw is using makes it seem like the GH5s could get updated to record out of the USB-C at least. (Like the pocket cinema 4k with raw)

Very fascinating. Perfect Joseph, great explanation. I know the Ninja 5 will do RAW when it gets released, but I hope Atomos do firmware updates to allow the Shogun and Ninja Inferno's to do RAW.

Great demo, especially with the lack of sample footage available right now. That highlight recovery is amazing!

Has anyone found links to good sample footage?

The Important Question is, is it as good as Cinema DNG? Or is it as blurry as B-RAW. The ONLY way to really! know is to shoot a Resolution Chart and Blow it up 3 o4 400% Next to Cinema DNG.

Hello! I have a great doubt and I would like to know what will be the best movement.
I have the Sony FS5 MK1 plus some Sony FE and Zeiss lenses, also the Sony a7iii and the sony a7rii, and the small a6300.
For my usual work, the equipment is sufficient. But I would like to have the opportunity to provide raw quality for specific projects, documentaries, video clips and even movies.
My initial intention was to acquire the RAW license for FS5. Buy Atomos Shogun inferno and SDI cable, 2 SSD and batteries.
The cost is about 2200 €.
Seeing the new blackmagic pocket cinema camera 4k I also consider this option to save weight and structure.
Which would be the best option?

Joseph! Thanks for this video bud! Quick question, what software and platform are you using to switch back and forth from camera to your computer and also the picture and picture shots? I am interested in implementing a similar layout for the iFilmmaker Podcast.
