| Summary | 0000050: Alpha Channel High CPU load | ||
|---|---|---|---|
| Revision | 2018-08-29 18:17 by gregk | ||
| Description | After upgrading to Wirecast 10, the use of ProRes video with alpha channels for graphics overlays is causing significant CPU utilisation. This behaviour is new in Wirecast 10, and was not a problem with Wirecast 9. Impact: Existing graphics overlays that previously worked without any problems cause so much additional load that streaming and/or recording fails. This bug was initially reported in https://wirecast.gregkuhnert.com/phpback/home/idea/29 - however, that issue is mainly focussed on the Rendezvous impact. The existing video demonstrating the rendezvous issue also demonstrates this issue at https://youtu.be/bZoLxVjLioM |
