In the context of video, “:30” and “:90” refer to the duration of a video or commercial in seconds.
- “:30” (thirty-second spot) – A 30-second video or commercial, a common length for TV and online ads.
- “:90” (ninety-second spot) – A 90-second video, often used for longer promotional content or storytelling ads.
The colon (”:”) before the number is shorthand used in the industry to indicate duration in seconds.
