Thanks for making the time. I want to start with framing — what was the original hypothesis behind the project?

S2

Honestly, maybe forty percent. The shape held — the mechanics underneath had to be rebuilt almost entirely.

Common questions

6 things people ask about this.

01Necesito extraer o audio do MP4 antes de subilo?+
Non. Sube o MP4 directamente. O audio extráese no servidor como parte do proceso de transcrición. Converter a MP3 primeiro engade un paso e pode reducir a calidade do audio se usas unha taxa de bits baixa.
02Que formatos de vídeo están soportados?+
Aceptamos MP4, MKV, MOV, AVI e WebM. Calquera contedor de vídeo cun códec de audio estándar (AAC, MP3, AC-3, Opus, PCM) funciona. Se o teu formato non está listado, proba a subilo — a maioría dos ficheiros de vídeo estándar funcionan.
03As marcas de tempo da transcrición coincidirán co vídeo?+
Si. As marcas de tempo anclanse á posición exacta no ficheiro que subiches, incluíndo calquera intro, cartel ou silencio ao comezo. Se queres que a transcrición comece nun punto específico, corta o vídeo primeiro — pero a maioría dos usuarios non o precisan.
04Podo obter subtítulos SRT a partir dun MP4?+
Si. Exporta SRT ou VTT directamente desde a páxina de transcrición e súbeos como subtítulos en YouTube, Vimeo, ou impórtaos no teu editor de vídeo. As marcas de tempo alíñanse coas posicións orixinais do vídeo.
05Cal é o tamaño máximo dun ficheiro MP4?+
Gratuíto: 100 MB (aproximadamente 10–15 minutos de 1080p), limitado a 30 minutos por ficheiro. Pro: 2 GB (aproximadamente 60–90 minutos de 1080p, máis a taxa de bits máis baixa), ata 10 horas por ficheiro. Business: 5 GB (varias horas de 1080p), ata 10 horas por ficheiro. Para exportacións longas de alta taxa de bits, o plan Business combina un límite de tamaño maior con cola prioritaria.
06Podo transcribir unha gravación de Zoom en formato MP4?+
Si. Descarga a gravación de Zoom como MP4 desde a túa conta de Zoom (gravación na nube ou local) e despois súbea aquí. A diarización separa o audio do anfitrión e dos participantes. Agarda un 95%+ no lado do anfitrión gravado localmente, 88–92% no audio do participante remoto.
