I believe sade actually stitched the shot of Rey to alter her mouth movements, so that it reads as “I’m a Jedi”, that’s what I meant works seamless/flows naturally.
Nope: the only shot I stitched together was to stick the ending of the “I am all the Sith” shot, where Sheev shoots some lightning, on to the “A scavenger girl…” shot which I’d swapped into it’s place, to maintain sync with the original music and all. I did this by lining them up, fading between, and then masking the lightsaber beam back in from both to hide the transition (this little bit of after effects magic I’m so proud of is available as a lossless mp4 on Mega). The rest, including the bit with Rey, is just taken from Ascendant as-is; the lips just happen to line up well enough.
