What is best way to extract a still from a video clip

Question

In a iMovie project there is a frame I would like as a still photo. Can I extract it from iMovie?

Answer 1

You can do it in iMovie '09 too. To export your still frames as JPEGs:
Choose Share > Export Using QuickTime.
Type a title for your movie in the Save As field.
Select the location where you want to save your movie. If the location you want doesn’t appear in the Where pop-up menu, click the blue Arrow button to the right of the Save As field, and then navigate to the desired folder.
Select the file format you want to export to from the Export pop-up menu (Select "Movie to Image Sequence)".
Click Options to see the default settings for compression, quality, key frame rate, frame reordering, encoding mode, and dimensions.
To change the compression settings (known as the “codec”), including quality and frame rate, click Settings (this option isn’t available for all export formats), and then specify your settings. Depending on the export format you choose, you see different codecs and compression options. If you select “Movies to QuickTime Movie” as your export format, you can make the following adjustments:
To change the compression type, frame rate, key frames, data rate, and compressor quality, click Settings. Setting a low key frame number (such as every ten frames) creates a better-quality movie with a larger file size. Set the frame rate last; you might get choppy-looking video playback if you set the frame rate to less than about 12 frames per second. Higher quality compressor settings result in a larger file size for your movie.
To add filter effects, such as blur, color adjustments, or “aging,” click Filters, and then select a type of filter from the list and make your adjustments. Any filters you apply affects the entire movie. You see a preview of your changes as you work.
To set the frame size, click Size, and then select a dimension setting from the pop-up menu and whether you want to preserve letterboxing. This size setting affects the overall size of your movie.
To export a silent movie, deselect Sound. Or select it, and then click Settings to change the default sound export settings, including format, sample rate, sample size, and channels.
If you will not be streaming this video on the Internet, deselect “Prepare for Internet Streaming.” Or select it, and then select a streaming type. If you select Hinted Streaming, you can further specify streaming behavior, including payload encoding, packet size, packet duration, QT metadata interval, repeat packets, and repeat interval.
After setting your preferences for export, click Save.
