Video Codec
The video codec is responsible for encoding and decoding video files. The choice of codec impacts file compatibility and performance across different platforms.
Why do we test it?
The most common codecs, like H.264 for MP4 or VP9 for WebM, ensure that your video ads are playable across various devices and browsers. Validating the codec prevents playback errors and ensures optimal compression for streaming.
