What is the format called that allows video ads to be played before, during, or after other videos, and is skippable after 5 seconds?

The format that allows video ads to be played before, during, or after other videos, and can be skipped after 5 seconds is known as TrueView in-stream ads. This advertising model is especially popular on platforms like YouTube. The key feature of TrueView in-stream ads is that they give viewers the control to skip the ad after the initial 5 seconds, which can enhance user experience by allowing them to opt-out if they're not interested in the ad content. Advertisers benefit from this format as they only pay when viewers choose to watch the ad after the skip option, meaning they are engaging with an audience that is genuinely interested in their message.

The other options, such as non-skippable ads, bumpers, and overlay ads, have different characteristics and purposes. Non-skippable ads must be watched in full before the main content, bumpers are short ads that cannot be skipped and last up to 6 seconds, and overlay ads are semi-transparent ads that appear on the lower portion of the video but do not interrupt the video playback.
