| Summary | 0000050: Alpha Channel High CPU load | ||
|---|---|---|---|
| Revision | 2020-06-29 11:30 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 0000029 - however, that issue is mainly focussed on the Rendezvous impact. This issue is also observed in the video. |
