Share one of your video projects that won't play after export.  Upload the project files to a server per the instructions here.

Someone will check it out.

Merge projects

The selected project will be merged into the current project and the merged result will appear on a new sequence. Placeholder video clips in the template project will be replaced by your clips on Video Track 1, and placeholder audio clips will be replaced by any unlinked audio clips on Audio Track 1. Only placeholders on Video Track 1/Audio Track 1 will be substituted.

Any effects, transitions or fades that were applied to the clips in the template will be preserved in the resulting merged sequence. If an overlay in the template ends exactly where a video placeholder ends, then in the merged result the corresponding overlay will have been stretched or shortened, if possible, to match the length of the substitute clip.

When editing is complete you can export the project in any number of formats.  The amount of time it takes varies by format, project length and other factors.

If export results in only audio, then obviously something went wrong.  Please share your project, per the instructions here, and someone will take a look.

Indicate what file format and resolution were used for your attempt.  Use version 7.01, released on 2/7/19.

Irrespective of what the track labels may say, higher tracks - those nearer the top of the window - take precedence over tracks below.

Higher-numbered tracks take precedence (overlay) those below, so fades must be specified for both tracks to achieve the desired result.

No, it's not necessary to uninstall.  In fact, if you have the latest version already installed, just go to the FILE menu, click on REGISTER SOFTWARE and input your code.

** UPDATE **   Tested your original file on the 7.01 release version (as of 2/7/19), and it loaded.

No problems combining your four clips.  Exported an mp4 at PAL 25fps.

You can edit the WMV, then export in any suitable format for your WEB presentation.

Or, later, if the AVI import issue is corrected, it should be possible to replace the WMV with the original file, per the Proxy instructions, and export that result.

Again, no guarantees.^_^

Mike, eyeing the source material it appears there would be little degradation in going with the WMV file.  Looks good here on a 24-inch monitor.   But, that's subjective of course.

Using the WMV as a proxy is an approach that would allow you to get busy with editing while the issue is addressed.  Here's how that works...

No guarantees, but it should succeed.  If not, it should at the least result in a usable production.

Understandable.  The bug is being addressed though it's unknown whether it will be corrected in a soon-to-be-released version.

Confirmed.  VP isn't seeing the full DV-camcorder file.  A bug report has been filed.

If you share your project someone will attempt to track down the problem.

Follow the instructions here, to upload it to a free server.   http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/

Please upload the full single file to a free server such as Google Drive, Microsoft OneDrive or the like.  You may have to create an account.

Then make it public (share it).  Paste that public link here, so someone can access it and download the file.

Click the FX button at the bottom-left of a clip.  The effects window appears.  Click the large green + sign and then the SCALE effect.

For more info click the ? at the top-right of the Videopad window, to see the help topics.  There are many tutorials...http://nch.invisionzone.com/topic/23872-videopad-tutorials/

Not here.

Update the video driver and Direct-X, if you haven't done so already.   https://www.nchsoftware.com/videopad/kb/1772.html

Tested four clips - up to thirty-second duration - without incident.  Halfway through there's a brief flash of a box that's titled "deshaker."

Post a link to a clip that crashes for you.

 AVI is a wrapper and may contain one of several codecs.

You can send a personal message (upper right-hand corner) with a link to a file if that's feasible, to see if your result can be confirmed here.

What file type are you attempting to load?  Upload a few files to a free server and link them publicly here.  Someone will take a look.  Here's how..

Best to start a new topic.  The thread is several years old.

Loaded your seven source files (plus the VPJ file) and Videopad indicated that no files were missing...

Yet video ends at about 1:20 while audio continues to near 3:10.  So this does not appear to be the completed project??

Also, the video files contain eight channels of audio each, which VP won't handle well.  Suggest that they be converted to two-track stereo.

Videopad can perform those operations, and there are many export options.  The best result is often obtained by matching the output format to the source format.

Link one looks exactly like the one I posted - all black.  The .png is also black, but does have some very minor artifacts towards the center of the image.

Monitor gamma may play a role in what you see.  Gamma of 2.2, the sRGB standard, is what is being displayed here.
