Compressed DNG Format

Adobe just announced DNG Specification 1.4 which includes lossy compression for RAW files. File size is said to be around 1/3 of the original.

Now that would be a stellar addition to the BMCC/Resolve package.

Cheers.

BMD - Please DON'T replace the BMCC's uncompressed DNG's with compressed ones - that would be the death nail for a lot of professional users.

Both would be good

I can't recall Blackmagic ever removing a feature. Perhaps you have an example?

Cheers.

No, but they have changed features. The required formatting of SSD drives is now Mac HFS+ rather than FAT

Possibly true, although the "DISP" button on the HyperDeck Shuttles continues to have no function whatsoever, a year or more on. But I agree: BMD generally don't take features away. Cheers.

For what product? The camera was never FAT.

On the other hand, Blackmagic just added exFAT support to the HyperDeck, but did not remove HFS+ with the upgrade.

In addition, they just added DNxHD support to the camera, and again did not remove anything in the process.

I'm sorry to go on about this, but I cannot imagine Blackmagic removing support for uncompressed RAW recording.

Cheers.

Noel, I wasn't suggesting that BMD habitually remove features from their products.

I was simply affirming that as a professional, I know a lot of people will still want the uncompressed option and that this great new format should not be treated as a substitute, but an addition as you said.

I may have been wrong about the format change, I thought I heard something about FAT32 being considered previously but this article alludes to HFS+ being decided since NAB http://provideocoalition.com/index.php/ ... g_rather_/

Adding to what Luke already said.. a lot of people (including me) would still pretty much prefer Cineform RAW support over some form of compressed DNG any day..

Hello.

according to the Adobe DNG Specification Paper,
the lossy compression is based on Jpeg and does 8bit color precision only.
Therefor the paper explicitly suggests it for proxy usage.

Would be ridiculous to buy a 12bit cam for recording 8bit...

BUT: Weren't there rumors of a ProRes RAW format? I'm not sure where I read it.
Perhaps only speculation; but would be great.
As long as ProResRAW is speculation, I vote for ProRes4444 at full 12bit.

Best regards,
Bernhard

If that's correct, it would certainly render it next to useless.

But a compressed version of RAW is obviously useful (e.g. REDCODE).

Perhaps what we need is BLACKCODE.

Cheers.

... and the SDK for NLEs is named Cryptex

Hang on - can PC users still read the files with macdrive?

If you are a PC user without a Mac how can you format the drive?
