I now have my first 23.976fps version of the clip ready for insertion into the main movie. I don’t have the bluray (or a full bluray rip) to do it myself but am happy to send anyone a link to the clip so they can have a go.
I will still be doing another (potentially better) version of the clip but I’m struggling for time at the moment so it might not be ready for a while.
Let me know if you want the link to the first version.
