The film is encoded once into several versions and cut into short segments. A conventional video file can begin playing before the whole file has downloaded. But a single version still has to serve viewers with very different connections and devices.
SeenThis encodes several versions before the campaign, with variable bitrate so complex scenes get more data and simple ones less. Each version is cut into short segments, listed in a manifest and served from a content delivery network; the player picks a version for each upcoming segment. Quality analysis compares encoded video with the source to help balance visual detail and data use. One of the measures is VMAF, an estimate of perceived video quality.
The visual below is a simplified illustration. Behind each ad, the creative is encoded in multiple codecs, bitrates and segment lengths, and playback adapts in real time to every viewerโs device and connection.


A price can stay editable text instead of becoming part of the video image. Connect that text to a feed, and the offer can change without rendering a new video.
The animation system follows the creativeโs playback timeline, so the layersโ motion can stay aligned with the video.
The video can be encoded for efficient streaming while the rest of the creative stays editable, so teams can work on delivery and design together.
