Best Practice and Recommendations

Bitrate: 1050 kbps

Duration recommendation: <15 seconds, especially on mobile

Letterboxing: Do not add black padding to the video as we dynamically pad the video with black borders to fit all site placements.

Volume is user-initiated; if you require subtitles, please hardcode subtitles to the video file.

Wrappers: If using a 3rd party vendor to ‘wrap’ the tag (e.g. viewability vendor), ensure that the wrapper accurately declares the creative types and dimensions that are contained in the tag.

The Telegraph Media Group has the right to reject any creative that does not adhere to these technical specifications. If you have any question, please do not hesitate to contact our Ad Operations team via email: adops@telegraph.co.uk
