Frequently asked questions
Is my video uploaded?
Video and audio stay on your device; they are not uploaded. First use needs internet to download the Whisper speech model from Hugging Face and the AI runtime from third-party jsDelivr CDNs. Your browser may cache these files. Keep the tab open; processing speed depends on your device.
Which videos are supported?
One MP4 file, up to 100 MiB and 5 minutes, with spoken audio the local converter can decode. MP4 is a container; not every audio codec is supported.
Do I need to convert MP4 to MP3 first?
No. Select the original MP4 directly. The browser reads its audio for transcription; a separate MP3 conversion is unnecessary.
Can I transcribe an MP4 without speech?
An MP4 needs a decodable audio track with speech. Silent footage and on-screen text are not transcribed; unsupported audio codecs may fail to decode.
Which language should I choose?
Choose the language spoken in the MP4 recording, independently of the page language.
