About Video Resizer
Last updated: May 2026
OptiPix Video Resizer modifică dimensiunile, rezoluția și raportul de aspect al videoclipurilor direct în browserul dumneavoastră. Alegeți dintre rezoluții standard (1080p, 720p, 480p) sau dimensiuni personalizate. Presetări pentru rețele sociale pentru Instagram Reels, TikTok, YouTube și multe altele. Opțiuni de raport de aspect: păstrați originalul, forțați 16:9, 4:3, 1:1 sau 9:16 pentru vertical. Utilizează filtrul scale FFmpeg.wasm.
How It Works
Filtrul FFmpeg.wasm -vf scale redimensionează videoclipul. Modificările raportului de aspect utilizează filtrele pad sau crop, după caz.
