Customer wants a video that loads quickly and starts automatically. What is the best format for this and does Dreamweaver support it?

asked for a quick, auto-starting video and the replies rightly touched on server and player choices. For a practical, modern approach: deliver an MP4 (H.264 video + AAC audio) as the baseline for widest compatibility, and include a WebM/AV1 variant for newer browsers to reduce bytes. Autoplay is frequently blocked unless the video is muted or started by a user gesture, so plan for muted/playsinline or show a clear poster + play control (HTML5 video element, ).

Start-up speed depends on both encoding and server delivery. Encode for the web (lower bitrates, sensible resolutions, short keyframe intervals) and move the MP4 metadata (moov atom) to the front so playback can begin before full download. Use adaptive streaming (HLS/DASH) or multiple bitrate files plus a CDN to improve perceived start time on slow links. Ensure the origin supports byte-range requests, correct MIME types, and caching headers — these server details are what was hinting at (Optimize video for the web, Range requests).

Note on tools and players: Dreamweaver is an editor and can insert HTML5 video or embed a JS player, but it does not change codecs or streaming behavior. 's Flash suggestion reflected older practice; Flash reached end-of-life and is no longer viable for web playback (Adobe Flash Player EOL). Use lightweight players like Video.js or native HTML5 with HLS fallback (Hls.js) when you need consistent controls and adaptive delivery.

Dreamweaver is just tool to help you with your development. It has nothing to do with video format or streaming of the content. I think I would do it as Flash player as it is able to read stream of various formats, can start play content after certain amount of data received and read rest of data on background while playing it. Good example is player on BBC website
