Does Sony package the images from a burst in a proprietary container that cannot be accessed by third party software? This is the primary reason I don't use 'raw burst' with my R6II. The other reason, as mentioned, is that once you start a sequence, the camera is locked out from shooting another one until the buffer is completely clear of the first burst. For things like birds launching, this might not be a big deal because it only happens once within a few seconds. For sports situations you might have anticipated a play incorrectly and started a burst, but half a second later the actual play you expected happened. Yet you let off the shutter release too soon because of the aborted first attempt and are now left waiting for the buffer to clear while watching the play you wanted to capture. Kind of reminds me of early digital cameras like the D30 (the one way before the 30D), which I think locked you out after a sequence until the buffer cleared. Don't want to go back to that experience. It's already bad enough having only 2.5-3 seconds of buffer depth at 40fps and CRAW. But then it's also my fault for buying a prosumer camera and not the R3 a couple years ago...  (no real regrets not getting the R3, just mid-tier model annoyances from time to time).

No proprietary container. Just saves the RAW files like it would if you weren't using pre-capture.
Sony doesn't lock you out, as long as there is some room in the buffer it will let you shoot even if it is at a reduced FPS.
Really with the A9III the only limitation to the implementation of pre-capture is that there is a buffer so depending on your settings you can run into trouble with slowing FPS.
Shooting at 120FPS was only good for very specific situations because the buffer was full in a second or two. But I started using pre-capture on all the time at 30FPS...there I could pretty much shoot like normal but was catching a bunch of shots my reaction time would have had me miss without it.
Even just quickly raising the camera to my eye to get on an unexpected BIF, I always wait to see that AF is engaged and tracking and then fire. With the no pre-capture that would always result in a few missed shots. With the pre-capture I'd still hit the shutter when I saw the AF was engaged but got a few shots that happened before I could react. It was really game changing.
I actually found I was accumulating less shots on the card because I could just react after I knew something cool had actually happened. Like tracking an osprey diving I really am looking for that talons on water...well normally I fire most of the dive, now I just hit the shutter once I saw it hit the water. Same with a swallow in flight...I have a million swallow in flight shots so the only shots I really try for anymore is bug in the mouth shots, normally with swallow I have to keep firing as it approaches and hope to snag the moment it darts in a different direction and goes for a bug. Now I can just keep AF active, tracking it without firing and only fire once I see the change in direction.
Game changing for my type of shooting...can't wait to have this feature in an A1II (the 24MP of the A9III was just too much of a step back after many years at 45+ MP so I didn't end up buying my own copy).
