About Video Resizer
Last updated: May 2026
OptiPix Video Resizer altera as dimensões, resolução e proporção do vídeo diretamente no seu navegador. Escolha entre resoluções padrão (1080p, 720p, 480p) ou tamanhos personalizados. Predefinições para redes sociais para Instagram Reels, TikTok, YouTube e mais. Opções de proporção: manter original, forçar 16:9, 4:3, 1:1 ou 9:16 para vertical. Usa o filtro scale do FFmpeg.wasm.
How It Works
O filtro scale do FFmpeg.wasm redimensiona o vídeo. Alterações na proporção usam os filtros pad ou crop conforme necessário.
Use Cases
- •Redimensionar para Instagram Reels
- •Converter paisagem para retrato
- •Reduzir de 4K para 1080p
- •Redimensionar para anexo de e-mail
