Red Triangles and videos disappear

[Phil J]

Can you tell me why after nearly completing my video, all the clips take on red triangles and the audio disappear and I have to start again!!

You should never have to "start again.".  Use Save Project File AS routinely, giving it a unique # or name, so as not to overwrite prior saves.  Using Save Project Files (no AS) will overwrite.  Then you can restore a project to the state it was in when saved.  Just double-click the VPJ file (which isn't playable).

What version of Videopad is being used?  Install this one. 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.

Does audio vanish in preview, or only upon export?  Let folks see what you see by sharing the project...

1.  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.
2.  Locate the saved, numbered folder and upload it to a free server - Google Drive, MS OneDrive, etc.*  (Don't upload the export or just the VPJ file.)
3.  Get a shared, public link. If using Google Drive click GET SHAREABLE LINK. Click the blue "Change to anyone with the link..."  Then click COPY LINK | DONE.
4.  Paste that link here, or click the folder, above top-right in this forum, and message it to me.  This is private and 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.
