Please check if your videos, images, or other creatives have this configuration before ingesting them into the ViewLift CMS, whether through the Tools UI or API:
Video Specifications
- Audio: The audio specification requires that videos have AAC 2-channel stereo or dual-mono audio. This means that the audio should have two channels, one for the left speaker and one for the right speaker. Avoid multi-channel.
- Video Codecs: H.264 | Apple ProRes
- Export your video in a standard container format. .mp4 and .mov are both good options.
- Aspect Ratio: 16:9 (preferred, but other ratios are acceptable).
- Frame Rates: Any frame rate is acceptable.

File naming
- Remove spaces, special characters, and extra dots from video file names before uploading.
- Special characters to avoid: !@#$%^&*()+=;:”’{}|[]?/,.><
- Use dots (.) only to separate the filename and file extension (e.g., .mov or .mp4).
- Replace spaces or special characters with dashes (-) or underscores (_) between words.
- Case sensitivity does not matter.
Common mistakes in content file naming
Image/video file names should only contain English characters and numbers. Avoid special characters and other languages to avoid issues as you can see below:
