MP4 export that survives phones
Exports on mobile were failing two times in three. The encoder now tries again instead of giving up, phones render at a size they can actually handle, and a failure tells you what to do next.
- FixedWhen a phone's hardware video encoder refuses to start — the most common way an MP4 export died on Android — the export now retries with a software encoder, then a simpler profile, then 720p, instead of failing the same way on every attempt.
- ImprovedPhones render MP4 at 720p. A full 1080p encode on a mid-range phone ran slower than the video itself and needed a quarter of a gigabyte of memory for a two-minute story, which is how exports got cancelled or the tab was killed. TikTok, Reels and Shorts re-encode every upload anyway.
- FixedAn export that was going to fail at the very end — the browser never handed over the codec details the MP4 needs — now stops in the first second instead of rendering the whole story first, and tries a different encoder.
- ImprovedIf MP4 export cannot work in your browser at all, the error now offers a one-tap switch to WebM rather than leaving you to guess.
- ImprovedThe screen stays awake while an MP4 renders on a phone, the same as it already did for real-time recording.
