Preview Waveform & Sound out of sync

Sound and waveform not synchronized

Quite disabling to my work.  On the sound tract that reads:

   ". . epidermis is the outer layer of skin that overlies that deeper layer of skin . ."

The whole word "epidermis" is heard BEFORE its waveform begins.

The video has been edited with a number of splitting, deletion and speed change.

The asynchrony cannot be a hardware or driver problem because if the video (exported from VideoPad) is played in WAVEPAD, the sound and waveform are perfectly synchronized.  Also, playing back the same original wmv file in VideoPad without any editing (splitting etc), the sound and waveform are also well synchronized.

New thread begun, as the original was over a year old.

Install the latest version.  For licensed users upgrades are free for up to six months from purchase date.  After that, VP will continue to fully function but a fee will be required in order to register the newest.  Retain your old install file and registration info.

If the issue persists, let's have a look at the project.  The process is easy, quick and can be done privately.  Just follow these steps...

  •     Back up --- With your project on the timeline, click on MENU at the top-left.  Click FILE|BACK UP PROJECT FILES TO FOLDER.  Choose a folder and SELECT FOLDER.
  •     Upload ---  Use a free server - Google Drive, MS OneDrive, etc.* - to upload the saved, numbered FOLDER.    Do NOT upload the individual VPJ or export file. 
  •     Get link --- Get a public link.  If using Google Drive click GET SHAREABLE LINK. If necessary change "restricted" to "anyone with the link can view" 
  •     Share ---     Click COPY LINK | DONE.  Paste that link here, or click the folder at the top-right of this forum to message it privately to me.  It won't be shared.

          *    Before uploading, right-click the folder, click PROPERTIES.  Look at the File Size to confirm that it's not too big for the free space on the server.
