ASF Editor: How to Edit ASF Video Files

ASF, also known as Advanced Systems Format, is a Microsoft file format that's used to encode digital video. However, you may find that many video editing tools don't support such kind of format. That’s to say, you need to convert ASF to other format before editing. Sounds complicated? Well, here a powerful video editing program- Wondershare Filmora (originally Wondershare Video Editor) is introduced for you to directly edit ASF without conversion. Interested? Now check out the tip below to see how to edit ASF with it.

1 Import ASF video to the program

To begin with the ASF video editing work, choose the aspect ratio between 4:3 and 16:9. Then click the“Import”button to add ASF videos as well as the images and audio files along with the videos to the main panel. You can also directly drag&drop them to the program.

2 Apply transitions and effects to edit ASF

Drag and drop the ASF videos, images and audio files to the corresponding timelines of the editing area. Double click the files on the Timeline, you can crop, rotate, set Contrast/Saturation/Brightness and fast/slow motion as you like. Or simply split and trim ASF video by moving the slidebar to left or right to remove unwanted part.

Then click the “Transition” and “Effect” buttons separately to choose from a wide range of amazing effects to add to your ASF video. To apply them, just drag the transition or effect you need and drop it on the timeline.

To add a subtitle for the ASF video, simply click the “Text”button to choose a style. Then drag it to the timeline, double click to enter the words or change the font, color, size and position as you like.

Besides what’s mentioned above, you can also add logo to video, apply picture-in-picture effect, change face, ect.
