What you can build

Web playback

Produce faststart H.264/AAC MP4, multi-rendition MP4 ladders, HEVC for Apple playback, or efficient AV1 outputs.

Adaptive streaming

Generate HLS or MPEG-DASH VOD packages with 1080p and 720p representations, manifests, and related media segments.

Social delivery

Fit landscape or square media into a 1080×1920 vertical canvas with a blurred background and no subject crop.

Previews and extraction

Create poster frames, palette-optimized GIFs, and sampled JPG frame sequences for previews, indexing, or datasets.
