Preparing a video ad
For broad compatibility, use progressive MP4 with H.264 video and AAC audio, sensible bitrate, and an explicit duration. A 16:9 landscape creative is generally easier to deploy across mixed players; 9:16 portrait creatives need players that preserve aspect ratio.
- Open Commercials and choose your MP4 or MOV file.
- Give it a useful title and set a click-through destination if appropriate.
- Select a skip setting supported by your audience's player.
- Upload and wait for processing to complete; do not repeatedly upload the same file.
- Preview the finished commercial and inspect its VAST tag.
Advanced users may import a direct, publicly reachable HTTPS MP4 URL. An ordinary watch page, m3u8 playlist, iframe page, or share link is not interchangeable with a direct MP4 media file in the current VAST generator.
Processing and delivery
MEDIARAZZI manages video storage and delivery behind its own branded media hostname. Some conversions are asynchronous. A freshly uploaded video can be visible in the library before its final advertising MP4 is ready.
Metadata
The server maintains duration and dimension fields. Use the real delivered rendition’s dimensions where possible. A file called play_1080p.mp4 should not automatically be assumed to be 2560×1440 or 1920×1080 without verification.
When playback fails
Verify the media URL returns video/mp4, is accessible over HTTPS, has no broken redirects, and actually decodes on the target device. Browser CORS and autoplay restrictions can also matter.
