About Video Resizer
Last updated: May 2026
OptiPix Video Resizer ändrar videons dimensioner, upplösning och bildförhållande direkt i din webbläsare. Välj mellan standardupplösningar (1080p, 720p, 480p) eller anpassade storlekar. Förinställningar för sociala medier för Instagram Reels, TikTok, YouTube och mer. Alternativ för bildförhållande: behåll original, tvinga 16:9, 4:3, 1:1 eller 9:16 för vertikalt. Använder FFmpeg.wasm scale-filter.
How It Works
FFmpeg.wasm -vf scale-filtret ändrar storleken på videon. Ändringar av bildförhållandet använder pad- eller crop-filter vid behov.
Use Cases
- •Ändra storlek för Instagram Reels
- •Konvertera liggande till stående
- •Skala ner 4K till 1080p
- •Ändra storlek för e-postbilaga
- •Beskär för presentation
