Trimming Away

It’s not always effective to show an entire video from start to finish. The interesting parts are usually sandwiched between lots of walking, talking, sleeping, or otherwise unrelated content.

In PowerPoint 2010, you get to choose exactly what to share using the brand new video trimming feature. Simply insert a video, and select the “Trim Video” option on the Playback tab. The Trim Video dialog will appear:

Trimming the video is as simple as dragging the handles at the edges of the timeline, or adjusting the time value in the “Start Time” and “End Time” spinners:

clip_image002

Now you can get straight to the point!

In a future post, we’ll show you how you can use trimming in combination with other new multimedia features so that you can conserve disk space when showing a short clip taken from a long movie.

  • Thanks for all of these posts! They are very helpful as I explore the new software.

  • I am extraordinarily grateful for an updated video system in PowerPoint. The video tools in previous PowerPoint 2007, 2003, etc. were severely lacking. One example that was very frustrating was that I couldn't see and edit the path to the video from the presentation. The only way to change the location of the video file being linked to by the video object in the presentation was to delete the video object and insert a new one. I often had to move videos to a different server because of space or bandwidth limitations, but this would break the presentation if I didn't manually re-insert each video. Another severe drawback has always been the limited number of supported codecs for playback. The general assumption was that a video will not play until it has been re-encoded with a format Windows can use. Part of the problem is that often presentations are not viewed on the computer they were created on. The viewing computer might be a fresh install of Windows XP that only supports MPEG 1 and WMV 9 and doesn't even have DIVX installed. If other media players like VLC, Mplayer, GOM Media Player, and Media Player Classic can have open source playback libraries for hundreds of formats, why can't PowerPoint have the baked-in ability to play nearly anything? Microsoft has finally embraced PDF and Open Document formats. There seems to be no reason why they would deliberately cripple their video playback to only allowing a few pre-installed codecs.

  • Thanks for the comments, guys! Brett - I definitely hear you re: the portability and the codecs. We've done some work around this that we'll talk about in coming posts.
