Very Basic Video Editing on the iPad

Very Basic Video Editing on the iPad

If you use the HD forward facing camera on the iPad (the one pointing away from you when you are looking at the screen) to take videos for use in class, you may need to do just a little editing before uploading the videos to YouTube or emailing them.  We checkout Flip and Kodak camcorders for this purpose too, and generally the only type of editing the professor needs to do is to trim the beginning and end of a clip.  There is almost always material at the beginning, when you are getting ready to start, that needs to be trimmed off, and sometimes material at the end to, when you realize you are finally done, that needs to go.  Here is how to trim video while previewing the video in our camera roll.

After shooting the video and returning to the home screen, tap on Photos, then Camera Roll.  The video you just took should be the last entry among the Camera Roll thumbnails.  It will have a little video icon on it, and a duration indicator.

Tap it in order to preview it full screen.  The preview window will have a thumbnail track at the top.  hold your finger continuously over the right or left end of the thumbnail track and two things will happen: 1) the keyframes will expand out, showing many more than were previously visible; and 2) the orders around the track will turn yellow.  Now you can drag the handles at the beginning and end of the track to a new location, to indicate where you wish to begin and end the video.  You can play the track as trimmed before committing to the trim.

Once you are satisfied that you have located a good begin and end point–and this is not easy because you do not have an audio track or even a very accurate video scrub to indicate the precise location, but it is good enough–tap the Trim button.

If you choose Trim Original you will destructively edit your video, losing the raw footage that you are trimming off.  If you choose Save as New Clip you will preserve the original and make a new video clip out of the trimmed video, which will also be added to the camera roll.  My own motto is, never edit destructively, since outtakes can often eventually be more useful than shots you originally thought were best.

Once you have your edited clip, you can then 1) Email it (it will be compressed to a 568 x 320 MOV file, down from 1280 x 720); 2) Include it in a text message; 3) Send to YouTube (where you will have the option of sending it standard definition or high definition, with consequent vastly different file sizes; or 4) Copy the video for pasting into another app.

It’s not the most sophisticated system ever, and if you elect to bring the video into a video editing program you will have much more control, but for a quick trim it has the great virtue of being easy.
