About Video Merger
Last updated: May 2026
OptiPix Video Merger combina 2-10 arquivos de vídeo em um único vídeo diretamente no seu navegador. Faça upload de vídeos, reordene-os e mescle com tratamento automático de formato. Usa o demuxer concat do FFmpeg.wasm para mesclagem rápida quando os formatos correspondem, ou re-codifica para formatos mistos. Todo o processamento é local.
How It Works
O demuxer concat do FFmpeg.wasm une os vídeos. Arquivos de mesmo formato usam -c copy para mesclagem sem perdas; formatos mistos são re-codificados para H.264+AAC.
Use Cases
- •Combinar clipes de vídeo em um só
- •Mesclar segmentos da GoPro
- •Unir clipes de entrevista
- •Combinar clipes de redes sociais
- •Mesclar gravações de apresentações
