Smart Bitrate Reduction
Overview
VOD's Top Speed Codec (TSC) feature can achieve high video quality at lower bitrates and help you reduce your traffic and storage costs. However, TSC transcoding fees are higher than general transcoding fees. This raises the question of how the TSC technology can be used to maximize your net cost savings (the reduction in traffic and storage costs minus the increase in transcoding costs).
With VOD's smart bitrate reduction feature, you can configure policies to automatically perform TSC transcoding on frequently played files. The general transcoding outputs of the files will be replaced with the low-bitrate files that are generated, while the playback URL remains unchanged, increasing your net cost savings.
Note:
Smart bitrate reduction works on a file ID level. If a media file meets the conditions of a bitrate reduction policy, the policy will be applied to all its transcoding and adaptive bitrate outputs in HLS format (which have the same file ID).
Smart bitrate reduction (TSC transcoding) does not work on files whose bitrates have already been reduced.
Bitrate reduction policies are not applied to transcoding and adaptive bitrate outputs generated before September 19, 2022.
