Trimming video start and end time in Flash CS3

To trim a video in Adobe CS3 first go to import --> Import Video. You will select the video that you wish to import. Once you have selected your Deployment to your video click next (I typically do Progressive download from a web server). Now we can start trimming. To trim the video you can trim the start time or the end time or both. To do this you will simply grab the bottom arrow and beginning dragging it in. You will do the same for the end arrow. You should see your video display as you drag the arrows in. This will allow you to set the exact portion of the movie that you want to play.

If you click on Crop and size under trim you should now see your new In point and Out point times. When your finished editing go ahead and click next. At this point you can add a skin if you wish. Click next again and then finish. You now have a video that has been trimmed to your exact play time. Enjoy!
