resolved Can't fade out an image clip

[Keith in UK]

For the first time I am having trouble fading out an image clip.  The icon at the end of the clip indicates that there is something attached to it, but there isn't.  I have magnified it to the maximum to check and there's nothing there. I have tried putting the clip on another track but that doesn't solve it. I've never experienced that before. When I try to fade it out it says the maximum allowed is 0.002! I've tried deleting the clip and reinstalling it but it makes no difference. Help!

If the clip is on track 1, switch to Storyboard mode and verify that the clip is not followed by a snippet of another.  Right-click on the track and CLOSE any GAP.

Try programming a keyframed TRANSPARENCY effect on the clip...        

To track this down take a minute to share the project.  Someone will help.  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.

Thank you for your detailed response.  Following your advice I eventually tracked down an offending fragment by letting the red cursor run until it stopped - way beyond the end of my video.  When I zoomed in to maximum at that point there was a thin, black line which I could click and delete and that resolved the fade out issue that I had.  A useful lesson learnt! Very relieved because I'm up against a deadline! Many thanks.  Keith
