Don't have ffmpeg installed?
 
     
  • Windows: winget install Gyan.FFmpeg — or download from gyan.dev/ffmpeg/builds and add the bin folder to your PATH.
    •  
  • macOS: brew install ffmpeg (requires Homebrew).
    •  
  • Linux: sudo apt install ffmpeg or sudo dnf install ffmpeg.
    •  
 
Verify it works: run ffmpeg -version in your terminal.
 
Codec & container notes
 
     
  • MXF OP1a — pairs with MPEG-2 video + PCM audio for broadcast delivery. H.264 in MXF is valid but less common; check with your delivery partner.
    •  
  • DNxHD / DNxHR — the bitrate value selects the profile (e.g. 185M = DNxHD 185, 36M = DNxHD 36). Use -vf "scale=1920:1080" with the matching Avid spec for your frame rate.
    •  
  • ProRes — quality is set by -profile:v, not bitrate. The bitrate field is ignored. Use profile 3 (422 HQ) for most post-production work, profile 4 or 5 for compositing with alpha.
    •  
  • 10-bit 4:2:2 H.264 — requires yuv422p10le pixel format and -profile:v high422. The generator adds this automatically.
    •  
  • WebM — supports VP9 and AV1 only. Using other codecs with a .webm output will error in ffmpeg.
    •  
  • MPEG-TS — the -f mpegts flag makes the muxer explicit; ffmpeg also infers it from the .ts extension.

Uses ffmpeg.wasm —
          the real FFmpeg encoder compiled to WebAssembly, running entirely in your browser tab.
          Nothing is uploaded. First use downloads ~28 MB (cached after that). Best for files under ~500 MB.
          Mode: single-threaded.

  
   
    
 Enable multi-threaded mode in production (.htaccess for cPanel) 
Add these two lines to the .htaccess file in your public_html root (or create one if it doesn't exist). They enable SharedArrayBuffer, which ffmpeg.wasm uses for parallel encoding threads.
 
Header always set Cross-Origin-Opener-Policy "same-origin"
Header always set Cross-Origin-Embedder-Policy "require-corp"
 
Note: these headers tell the browser all cross-origin resources on the page must opt in. All resources used here (jsDelivr CDN) already do. If you add resources from other domains later, check they serve Cross-Origin-Resource-Policy headers too.
