ASX enforces no hard limit on the maximum weight of media files. However, media may enforce limits, consult your specific publisher if you want to be sure that your material is within limits. We recommend adhering to the specification below.
Media file types: MP4 (H.264) and MOV are preferred formats. A video creative may have several file formats, to cover the needs of different publishers and media players.
Format: 16:9 (preferred) or 4:3
Resolution: At least 640x360px. Preferred 1024x576px.
Bitrate: Maximum 2500 kbps.
Length: maximum 30 seconds. Many inventory sources use 15 seconds. Please consult with your campaign manager and choose according to targeted media.
Weight: There are no hard limit on the weight of the media file(s). But the maximum bit rate will limit the weight.
If a wrapper is used, it needs to be VAST 2.0 compliant.
Please verify that no targeting is made at the third party providing the wrapper, as this will interfere with creative audit and campaign delivery.
Only 1 creative per wrapper.
- No black start- and end screens
- 1 creative per channel
- If a video is declared as ssl compliant (which our videos are) all assets down the chain needs to be ssl compatible, take special care to verify this if a wrapper is used.
- The lighter the weight of the creative, the faster it loads and the better the user experience
