Here’s a quick tip on exporting still images from an HDV video sequence. There are various occasions where this might prove useful. The one I came across recently was needing stills to add to the cover of a DVD of an event. The HDV format makes this slightly less than intuitive, so read on for a quick guide.
OK this quick guide assumes you have the following:
- Some 1080i HDV footage (e.g. from Sony Z1U or HC1)
- An NLE that can capture HDV
- An image editing app like Photoshop or photoshop elements
- First capture your HDV footage into your NLE (I’m assuming you know how to do that bit)
- Move the cursor to the frame you want to export.
- Export that frame as a still image. Exact method depends on the NLE. In FCP 5 it’s FILE…EXPORT USING QUICKTIME CONVERSION then change the file type to ‘still image’ and select your preferred type – e.g PNG or JPG. I’m pretty sure there’s a ‘save as still image’ option in iMovieHD as well.
- Open your still image file in your image editing app
- Apply a de-interlace filter (in Pshop it’s FILTERS..VIDEO..DE-INTERLACE). This gets rid of any ‘combing’ effects caused by movement between the two interlaced fields.
- Resize the image from 1440×1080 to 1920×1080 pixels. This corrects the aspect ratio of the image.
- Adjust brightness, highlights, shadows etc. to taste.
- Save your image (In PShop, SAVE TO WEB will let you optimise the image for minimum size while maintaining quality).
- You’re done.
