Hi,
Thank you for posting your query on Microsoft Community.
I suggest you to follow the methods below and check if it helps:
Method 1: The duration change must be made 'before' the photos are added to the timeline. Follow the steps below to do the same:
- If you switch to 'Storyboard' view and select all the clips as a batch (select one and type Ctrl+A), you can add the "Speed Up, Double” or "Slow Down, Half" effect to change the duration.
- Just select all the clips / right click the Effect and from the menu choose Add to Storyboard.
- "Speed Up, Double" cuts the duration in half.
- "Slow Down, Half" doubles the duration.
- These effects can be added up to six times.
**Method 2:**You may change the duration for each clip manually. Move your pointer around on the edge of a clip until you see a double red arrow. Now drag the double red arrow you'll see a tooltip that shows the duration changing. Or just redo
the project 'after' you change the duration at: Tools / Options / Advanced tab.
