ViewLift Video Specs & File Naming Best Practices

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.

Best practices for ingesting video files into ViewLift

• Container: MPEG-4
• Video Codec: H.264
• Video Bitrate: Use the source bitrate.
• Video Resolution: Preferred resolutions are 1920x1080 and 1280x720 at 16:9 aspect ratio. 
• Audio Codec: AAC
• Audio Bitrate: 128 kbps or higher.
• Framerate: Follow the source framerate.
• Aspect Ratio: 16:9 is preferred. Avoid letterboxing and pillarboxing if possible.
• Scan Type: Progressive. This will ensure that your video plays smoothly on all devices.

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
