REAL RAW ON VIDEO ASSIST?

PostThu Nov 30, 2023 5:27 pm

What we know:

- Internal BRAW is NOT actually compressed RAW because of RED's patent

(RED has a patent on internal compressed RAW recording.)

Question:

- Is the BRAW recorded externally to the VideoAssist "real" RAW (compressed)?

My guess is no. The inner workings in terms of encoding of the Video Assist is probably similar to what they have in-camera. This would also save them development costs and possibly share some hardware and software between the devices.

The output from compatible cameras is "real" raw. When recording that data stream as Blackmagic Raw, the Video Assist performs the partial de-bayering (or de‑mosaic) and compression, the same as the BMD cameras do when recording BRAW internally.

So both internal and external BRAW is partially de-bayered. Both are compressed (the patent doesn't apply because it's no longer raw in that sense).

No, but for most people it doesn't really matter as BRAW gives you many of the upsides of raw and none of the downsides.

The partial demosaic is performed in the Video Assist, cameras don’t differentiate between raw and braw output.

Beyond that it’s “real” in every way that matters. Is Q0 less real than ELQ?

Good Luck
