Changing Video Link Paths

julianpaul · #1 09-02-2012, 05:56 AM

I have a PowerPoint presentation with Video files linked to disk files. The Videos stop working because the paths become incorrect when moving the PowerPoint file around to different machines.

Under File/Options/ "Edit links to files" one can see the paths but one can only open the source and "change source" option is greyed.

One can update them individually by trying to play each video. Painful

I am looking for a vba script to change the path of these linked videos. I have done this in Word 2010, but do not understand PowerPoint objects.

Thanks for your help

Are there things you are not telling us?

Video is embedded by default in 2010 AND if you choose to link it IS possible to edit the link.

Maybe this is a file from an earlier version or you are in Compatibility mode??

You need to say - it matters!

It will also help if you say how the linki will change eg C:\ becomes D:\ or "MainFile" >> "SubFile"

Hi John,
Not copatibility mode, but file was saves as a pptx probably (don't know history). Just did a test and yes it obviously came from past versions as Insert/video from file does not create links in a fresh file.
Path would change from say c:\a to c:\b\c for example.

If you decide exactly which part of the link needs to change you should be able to do this.

Code:

Sub change_path()
Dim osld As Slide
Dim oshp As Shape
For Each osld In ActivePresentation.Slides
For Each oshp In osld.Shapes
If oshp.Type = msoMedia Then
If oshp.MediaType = ppMediaTypeMovie Then
On Error Resume Next ' in case there are embedded videos
If oshp.LinkFormat.SourceFullName <> "" Then
'original was C:\users\John\Desktop\MyVids\vid.wmv
'new path is C:\users\John\Desktop\MyNewVids\vid.wmv
oshp.LinkFormat.SourceFullName = Replace(oshp.LinkFormat.SourceFullName, Find:="MyVids", Replace:="MyNewVids")
End If
End If
End If
Next oshp
Next osld
End Sub

Many thanks John
I understand the code and did a trial and it works. One point is that PP wants to embedd it and if I say yes it just plays a blank avi. If I say no it works fine.
Now I will write a front end and post it for others when finished.
Appreciate the help.
Julian
