# Limit on thumbnails in MediaLive
<a name="thumbnail-limits"></a>

There is a limit to the number of MediaLivethumbnails that you can view or retrieve. The limit is:

`A number of API transactions per second, per account, in one Region`

The transaction limit is shared by all thumbnails — those that you display on the console, and those that you retrieve using an AWS API. For the current limit, see the MediaLive page in the [Service Quotas](https://console.aws.amazon.com/servicequotas/home?region=us-east-1#!/services/medialive/quotas) console.

On the console, a thumbnail is generated for a channel only when the channel details page is displayed, and only in the active tab (meaning only for one pipeline in the channel). For the relevant pipelines, MediaLive makes a call to the API approximately every 2 seconds.
