How to Grab a Still Image From a Video

Sometimes you just need a single image instead of a video: it might be for emailing to someone on a dialup connection, or for printing out. So how do you grab a single frame from a video? It’s easy to do...

 

Firstly, you’ll need to get your video from your camcorder onto your PC or Mac.

 

If you have a digital camcorder and a PC, this is easily done with Microsoft’s free MovieMaker 2 software, which comes with Windows XP Service Pack 2: details here. Go through the process to capture the video that includes the frame you want to grab, then select it in the content pane (the one that shows the thumbnail of the first frame of the video). Using the controls below the preview window (the one on the right that shows the video itself), move through the clip until you find the frame you want to grab and pause. Then go to the Tools menu and select Take Picture from Preview, and tell it where to save the file. You can now send the captured frame (which will have a resolution 640 by 480 pixels) by email or load it into any paint program and do what you want with it. For reasons best known to Microsoft, if you use the timeline to capture an image, you get a lower resolution image.

 

If you have an Apple Mac, you can go through a similar process using the iMovie software that’s included with most recent Macs: capture the video, go to the frame you want, then on the File menu, select Save Frame As…

 

One thing that you will notice is that if the frame contains a lot of movement, you may get an odd-looking jaggy effect (see the example on the right): this is caused by the movement of objects between the two alternate fields of video that the software combines to form the image. Some software (such as Premiere Pro and Pinnacle Studio) has ways to try and get rid of this: a process called deinterlacing. There’s a good (if a little technical) explanation here, and there’s a good guide to how to get better looking still images if you aren’t afraid of a bit of Photoshopping here.Check the documentation of your video editing program for more details: different programs have different ways of dealing with this problem.
