Sound cutouts on MOV-files

Hi Forum!

Recently changed from Pinnacle Studio 14 to PowerDirector 13 and generally happy.

I had this old project recorded as MOV-files from a Panasonic Lumix TZ-7 in the hopeless 848 x 480 resolution. Pinnacle made a grainy mess out of the video (I tried to export it as 1280 x 780). Out of curiosity, I took this video as my first "pilot" on PowerDirector and the video quality of the output file was just so much better! So I remade the whole project manually in PowerDirector to save these valuable recordings

BUT - now I experience that on approx. every 5th clip in the video, the sound on the exported file starts about a second later with just silence at the start? Funnily enough, it is not alwyas on the same clip, though some clips are more prone to this error than others. A re-encoding of the project solves some of the errors, but creates new ones on other clips in the project.

Being a Pinnacle user, I am used to try out various work-arounds - so far in wain:


  • Cut off the first 3 frames of every clip to enforce recoding - no luck

  • Unlink video and audio, then copy audio into a blank project to produce just a wav-file to add back to original project - no luck, cut-outs in wav-file too

  • Making a movie from blank with just 5 of the clips - works rarely, but fails randomly

  • Clear Cyberlink cache - no luck


Is it possible to find a solution to this problem?

PowerDirector works fine (so far!) vith new H.264 AVC 1920x1080 files from my new Lumix TZ40.

Kind regards and thanks!

Are the Audio portions of the MOV videos encoded as MP3?

If so, converting to WAV would likely solve the audio problem. WAV encoding of audio always works well in Powerdirector.

Audio extraction in Powerdirector is Right Click on the clip in the Powerdirector library > Extract Audio.

Otherwise, an external file converter may work.

One option that may work in some cases, select the video.

Button Edit Audio / WaveEditor or AudioEditor, do any editing to ensure the creation of new audio file. AMD-FX 8350 / 8GB DDR3

Hi there!

Thanks for your suggestions!

PowerDirector properties on original audio says:
Type: LPCM
Sampling rate: 16 kHz
Bitrate: 512 Kbps
Channel: Stereo

Adding +1 dB in WaveEditor seems to do the trick - thanks!
This is a do-able workaround (which I am used to from Pinnacle), but I would of course prefer an overall technical fix.

I will see if the WaveEditor trick is the general solution and write back.

Meanwhile any technical explanation is welcome wink

Kind regards and thanks!
