How do you figure? You take a single image, then move the camera or adjust focus, lather, rinse, repeat. In video, you do the same thing, except now you have to process each video clip to get export the single frame.
No, you record a single video while moving focus and export each frame - that’s what makes it easier.
> The camera itself is mounted on an old edelkrone slider with a motion module. I record short 4K ProRes422HQ clips and use them for focus stacking directly in helicon focus. For this fly I used an average of 160 frames [from one clip]

Clearly, he recorded multiple clips, and then exported individual frames from individual clips.
After all of that, he didn't even record in RAW.
This is a film production company, they most certainly have a stack of DSLRs they could use it it was that much more convenient, and with much better resolution. Not sure why you’d assume stupidity.

As for RAW, unless you need that bit of extra dynamic range, it makes no difference (they don’t here, as it’s a studio shot with fully controlled lighting), ProRes422 is enough for 10-bit HDR even.
And sure, it's not raw, but ProRes422HQ is pretty damn good, being both high pixel depth and very high bitrate.

Also, can you please make your criticisms thoughtfully rather than as shallow dismissals or snark? Your comments in this thread are rather on the wrong side of the line, starting with https://news.ycombinator.com/item?id=26427684. You obviously know a lot about this topic, which is great, but the thing to do with that knowledge is share some of it, so the rest of us can learn, and leave out the putdown aspect.

Plus, a lot of RAW files are TIFF, so I'm sure GPU-accelerated stacking is in reach.
