What is SWF?

SWF file is an Adobe Flash file format developed by Macromedia and is now held by Adobe. It can contain video, text, vector graphics, raster graphics, and ActionScript. However, Adobe has precluded Flash content from running in Flash Player since January 12, 2021, rendering SWF unplayable. Then you need a SWF file editor or a Flash decompiler to convert and edit SWF content.

This post introduced five SWF editors to help you convert and edit SWF video files and other content. Just choose a suitable one according to your SWF file content.
(Part 1 shared an SWF video editor to help users edit regular video files on Windows. You can also jump to Part 3 to find some SWF decompilers.)

Step 1. Import SWF Video Files

Step 2. Edit SWF Files

There is a toolbar with some video editing tools under each video task. You can press each of them to edit videos. And if you want to merge videos together, you can press the “Merge” button at the top menu bar. I'll go over some of the most important video editing features in detail below.

1> Merge SWF Videos

To merge videos into one file, you need to add at least two videos or more video files. Then click “Merge” on the top menu bar to enter the video merging window. The imported videos will be placed under the Video List. Select the video you want to merge into one clip and click the middle “Merge” button to save them in Pack 1. You can then adjust the video order in the pack. (By repeating the process, you can create multiple video packs without importing videos again and again.) Finally, click the bottom “Merge” button to save the change.

2> Trim SWF Videos

Click the scissors-shaped icon on the toolbar to enter the video trimming window. Here you can move the sliders on the two sides to select the wanted part or type in the exact start and end times to make the cutting video more accurate. Then press the “Trim” button to cut the video clip. You can also repeat the process to split a long video into multiple parts. Finally, click “OK” to go back to the main interface.

Press the circle-shaped icon, and then you’re in the video rotating window. You can rotate the video 90 degrees clockwise or counterclockwise, as well as flip it horizontally or vertically. Tap “OK” to go back.

4> Crop SWF Video

Click the square-shaped icon to enter the video cropping window. Here, you can freely crop the video to select the cropping area by dragging the dotted box under the “Free Aspect Ratio” mode. You can also choose a fixed common aspect ratio like 4:3, 16:9, etc. from the “Fixed Aspect Ratio” drop-down list and drag the dotted box to the desired place. Fine Tuning helps you make the cropping area more accurate.

5> Apply Effects/Filters to SWF Video

Asides from the illustrated video editing features, you can also press the last icon on the toolbar to edit the video metadata, click the first “+” button on the toolbar to add subtitles to the video and press the second “+” button to add or replace the background music of the video. You can even click the compression button at the bottom of the interface to compress video in batch mode.

Step 3. Export the Edited Video

If you want to change the video formats, you can press the format image on the right side of the interface to choose an output video format under the "Video” tab. (You can also click “Parameter settings” to change the video codec, resolution, bitrate, sample rate, etc.) Finally, set an output folder by clicking the bottom inverted triangle button, and then hit “Run” to start processing the video.
