Interesting differences in PD9 behaviour with ATI graphics :
- On my PC release 2504 crashes to a point of nuisance, 2330a much less so, and this after updating ATI to release 11.1 (previous version had same effect).
- Testing the differences between hardware (ATI) acceleration turned off and on, I can concur with Andrew's results : the AVC video is not as detailed in visual quality. This can also be confirmed by checking the produced video details (select properties of the video file in the media room after the file is rendered) and one finds that the average bit rate is 4 - 6 Mbps LOWER with the ATI acceleration turned on. This test was using 1920x1080i rendering mode. (The hardware (ATI) acceleration effect can be verified using ATI's new AMD System Monitor software available on the same page where the ATI Catalyst application is found.)
It is unfortunate that the ATI encoding is not as high a bit rate, because in terms of rendering time I've clocked anywhere from 25-50 % improvement ! That is substantial on larger projects.
Important user note: even when the acceleration features are disabled in the Preferences tab, PD still insists on selecting it in the Production window. To have only CPU based rendering one has to deselecte this as well.
Anyone care to do similar tests ?
