No audio (and other major problems when adjusting clip speed above 2x):"keep audio" box is checked

I started a topic about some serious problems I am having with clips on my timeline going crazy. Here is that topic (which goes more into the other issues that seem to be initiated by the clip speed changes. I also posted a link to a video showing one of the symptoms in action): http://forum.cyberlink.com/forum/posts/list/45933.page . Since it seems most likely to happen after I adjust the speed of a given clip, I thought I'd approach this from a different angle in case the title and wording of that topic leads people away from what may be the real root of the issue. So please forgive my posting a second topic.

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.

Hi Steve

I glanced at your other thread and it looks like you're running into quite a few problems. On the audio issue you're describing here, PD is operating exactly as it's supposed to. PD14 (and 13 and many more earlier versions) only allow audio when the clip speed is between 0.5x and 2.0x.

The audio is ALWAYS muted when clips are set to run faster or slower than those speeds, and here's a direct quote from the Help file's Video Speed section:

Audio setting:

•Remove audio: select this option if you want to mute the audio in the entire video clip.

•Keep audio: select this option if you want to keep the audio in the edited video clip. Select the Keep audio pitch (0.5X to 2X only) if you are changing the speed of the video. Selecting this will stretch the audio to match the new video's length, minimizing the warping of the sound as the video speed changes.

I appreciate your response, but I think you're confused. In PD13 it's true that audio is always muted when the clip is sped up above 2x. But in PD14 (and this is one of the features I highly value... when the feature is working) there should be audio present - even above 2x - unless you check the box to remove audio. The part that you made red above is simply pointing out that above 2x, the audio can no longer be made to maintain the original pitch. So, as a result, the audio pitch will be raised more and more towards the "Chipmunks" range the faster the speed is increased.

I see what you mean. I hadn't even seen the new "keep pitch" tool before but it works as you described it. On my system I can keep the pitch within the 0.5x to 2x range and I get the full chipmunk effect at higher speeds as long as I have Keep audio selected.

You haven't posted the DxDiag specs for your machine in either thread, and it might be helpful if you could run the test and post the results as described in Part B of the Welcome sticky at the top of the PD14 forum index page.

As I posted in the other thread, packing and uploading your project and sharing the link will let other people see what's going on with their own machines, and that will probably help solve most of the issues.
