AI lip-sync still breaks on pre-existing clips, even with matching audio

The author says lipsync and AI video editing are still far from reliable on pre-existing clips that need to be reworked.
- They tried five specific video clips with matching audio tracks for a music video featuring an unusual face.
- All five attempts failed across the board, which they describe as laughably bad.
- They suspect either Sync 2 cannot handle the task even on Pro, or that other providers require very strict limits on clip/audio length.
- In cases where other clips did work, the face got altered slightly, which is also a problem.
Their conclusion: this workflow is still agonizingly fragile.
