Is the original audio preserved?

English and Roman Hinglish (Hindi in Latin script). No Devanagari or Arabic script is used.

What happens if transcription fails?

If we can't detect clear speech, we show an error and you're not charged. Upload a video with clear speaking voice.

Are credits charged before or after?

Credits are reserved only after Lambda accepts the render and settled only after a successful MP4 is generated. Failed renders release credits.

Can I use portrait or square videos?

The renderer preserves aspect ratio using object-fit: contain. Landscape 16:9 videos produce the best result.

What if my video is over 10 minutes?

Currently the maximum is 10 minutes. For longer content, split your video before uploading.
