# 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

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:
