What ZRAW actually is. ZRAW codec reverse-engineering.

[@JonRatzlaff]

This was INCREDIBLY informative!

[@magicnightcn]

Why do manufacturers have to take various tactics for in-camera recording of RAW video, or use such devices as Atoms to record externally, just because of RED's patent for compressing video RAW and storing it in the camera? I think it's as ridiculous to patent a principle as it is to patent "eating with forks and chopsticks".You can patent all kinds of algorithms of encoding, decoding, and file formats. But to just patent the method of "compressing data from the sensor and storing it on the camera's memory card" and using that to stop other manufacturers is an industry monopoly, and most of the time, industry monopoly is not a good thing. I respect RED's position in the industry and their vision, but I am not proud of what RED has done.

Great points, I agree!

[@lukabalta2398]

is it tho ? money they make just says it was the right move unfortunately for us. and still we all drool after red cameras

[@darrenorange2982]

When is the converter being released? This would be extremely helpful as we are shooting a feature shooting the whole thing in ZRAW.

@@StoryboardCreativity I'd like to engage on this privately, as I have tested your code and created HEVC output from 0.98 firmware RAW files.

[@rogmag74]

Since the official ZRAW decoder uses a custom FFmpeg they are bound by the FFmpeg license to release their changes to the source code. I wonder if they are even aware of that.

[@StoryboardCreativity]

Can you provide the source of this info? It will be very useful for me!

[@joesalyers]

@@StoryboardCreativity Look at the FFMPEG License page. FFMPEG uses the GPL, if I post the link youtube will make it disappear since links are not allowed. But FFMPEG is open source and the GPL requires added code be shared and open.

[@StoryboardCreativity]

Does it mean that they have to publish only changes to ffmpeg? Or whole their VideoSuite source code?

[@joesalyers]

@@StoryboardCreativity Any code that involves the use of FFMPEG to encode or decode ZRAW. This only applies to FFMPEG and not their VideoSuite itself. But if Z-Cam are using parts of any Opensource code in the VideoSuite you could look through those to find out what is going on under the hood. All software that uses Open source GPL code must inform the end user of that code. Even Apple uses GPL code and you can usually find out what code is being used by looking through the help tab or just doing a quick google search for ZCam or Zraw and open source licenses.

great work! didn't understand everything, but appreciate you sharing it :) keep it up!

[@StoryboardCreativity]

Thank you!

Do Hi, please tell me.)Do I need to convert Prores Raw HQ to log? and then in cus. 709 save the dynamic range or is it not required? If you translate to Log, then which one to choose in source - (V-log???) then which input lut should I use?I need to convert Prores Raw HQ to log? and then in cus. 709 save the dynamic range or is it not required?

[@rezaVfx]

Ouch! Thx for this very helpful info! What about Braw! Is it still mov or real raw?

[@jessehorstman]

Thanks

[@EmmysVerySeriousVideos]

So what happened to Zraw after the updates ? Is it still raw ?

[@StoryboardCreativity]

No, it's not.

[@EmmysVerySeriousVideos]

@@StoryboardCreativity:(

[@StoryboardCreativity]

@@EmmysVerySeriousVideos you can use hacked firmware to get RAW

[@EmmysVerySeriousVideos]

@@StoryboardCreativityguess I’ll try that, but I haven’t bought a zcam yet and I’m debating getting a red or black magic. I love the specs and price of zcam tho, just sucks to have to hack into the camera to get raw because red is greedy. Do you know anything about the compatibility of the « hacked » raw files and davinci resolve ?

[@StoryboardCreativity]

@@EmmysVerySeriousVideos DNG is supported by Resolve. But hack is available for E2 and E2-M4 only

[@heartshapedfilms]

4 minutes in. Very well executed though it seems your forgetting that all internal RAW video codecs can't be full RAW due to RED stupids patent. Restricting innovation, competition and monopolizing the market, hence Prores Raw. Though this isn't real Raw either and as such the reason why Apple had a lengthy court battle trying to throw out Reds patent though somehow they won.

[@StoryboardCreativity]

If you watched 4 minutes only, you did not see, that in 0.93 ZRAW is a real internal RAW

[@heartshapedfilms]

@@StoryboardCreativity yeah that would of help I did leave it to be fair not for any real reason. Just think I did something else just felt a lot of info was stated before mention some of the RED patent.

[@RedEyrisFilms]

Cause red is a piece of shit. Everyone knows this just cause they do really stupid crops on their over priced cameras they dont care about their customers at all.

Я не искал это видео, оно само мне попалось в реках Ютуба, я все равно ничего не понял. Тем не менее, ты невероятно крут и я очень рад, что мне довелось учиться с тобой в одно время, в одном учебном заведении в Петергофе🥲👍
