In short, almost every time I adjust the speed of a clip above 2.000x the clip mutes and nolonger has audio. And this happens even though the "keep audio" box is checked. When it works properly (rarely) the audio remains but is simply at a higher pitch than normal when sped up above 2.000x . Frankly, the problem MAY occur when adjusting speed within the 1.000-2.000 range, but I'm not sure. I THINK it only happens above 2.000x speed.
Adjusting clip speed is also causing other strange and frustrating problems in a large number of cases. And since I generally speed up every clip I add to my timeline this bugs render the program almost unusable for me.
I "upgraded" from PD13 to PD14 about two weeks ago. 13 worked great on my system. 14 has always been plagued with this set of problems.
I'm running PowerDirector Ultimate 14.0.2019.0 (16 bit). I've tried reinstalling PD14. No change. I then installed the two beta patches (v2207 ; v2019). No change.
Windows 7 , 16GB RAM
Any ideas? I hate the thought of having to revert back to PD13 and losing all the great new features of PD14 (and all the money it cost me). Thank you very much for you time.
