If you generated a longer video recently and noticed scenes missing or out of order, this is the fix.
What was happening: when Pitvi asked the AI to write every scene of a longer video in one shot, the response would sometimes hit an internal length limit and get cut off. The result: gaps in your video.
What changed: scenes for longer videos are now built in smaller batches running in parallel. Tested up to 12 scenes without truncation. Most generations also finish a touch faster as a side effect.
