as I said earlier, what matters is that your scene cuts match the BL. The framecount mismatch makes the graph look different.

Ok so I finished transferring cmv4.0 for Blue Beetles 2023 and am doing the final checks. The RPU_CMV4.0_L3L8L9_transfered.bin's L1 plot matches the original bluray file's. I exported the scene cuts using verify_sync2 file and am checking random frames at the beginning and the end of the final mkv file to make sure they are the first frames of a new shot. I found one that isn't: Frame 657. Frame 656 and 657 are still in the same shot. I checked randomly many other frames and they are all the first frame of a new shot. Why is this frame 657 not?
Edit: Found another one that is not the first frame: frame 5503. The similarity between this and frame 657 is that they both seem to be part of a very wide shot.
Also, some of the frames listed, e.g. 49, are from early in the movie and they are just part of a black screen sequence.

Maybe automatic scene-cut detection? It happens sometimes, most of the time, a flash or fast movement can cause that and it doesn't really matter. I've seen this many times on retail RPU.

Why are some web releases cmv2.9 instead of cmv4.0 I wonder?

@RESET_9999 I'm testing Aquaman.and.the.Lost.Kingdom.2023 and during workflow 1-1 (inject RPU_CMV4.0_L3L8L9_transfered.bin to original bluray file) I get this missing L5 lines. Should I just press enter to skip?

You can't skip it, this workflow was designed to always fix incorrect L5.
Just edit it to 0,0,0,0

Besides missing L5, when and how do we know L5 is incorrect and needs to be fixed?

I just downloaded two web releases of John Wick 4 in order to test the rpu transfer and both are cmv2.9. Sigh. This takes too much time.

Ah ok. It's confirmed to be cmv2.9. No point doing the transfer then. Will try a different movie that is not on your spreadsheet.

Btw, I'm measuring the black bars for Dune 2 to see if I need to edit L5. Checking the bluray version and the top and bottom are both 276. For the stream version, there's no black bar (L5 missing). So I thought I would need to put in 276 for top and bottom when editing L5 in workflow 1-1. However, when I drag RPU_CMV4.0_L3L8L9_transfered.bin into workflow 1-1, the top and bottom are already 276 there. So does it mean I won't need to edit L5? Why is that?

the L5 on the P5/P8 web-dl has nothing to do with the one on the bluray P7 rpu when you transfer cmv4.0 and L5 is almost always correct on bluray. It's just Apple and MA that are stupid.

Hmm ok. So for all the cmv4.0 transfers just type in 0,0,0,0 (i.e. pressing enter)?

No, and the script will force you to edit L5 only when its missing.... Watch the P8 hybrid tuto, I show how to measure the black bars of the BL and edit L5 when necessary
