Step 5: Customize the output file size (optional)

To customize the output SWF file size, highlight the source file, click "Tools > Bitrate Calculator", and type the file size you want in the "File Size" textbox, then the video bit rate will be auto-calculated directly. Click "OK" button, and the value you type will be shown in the "Output Size" column of the file list.

Step 6:Start the conversion

After all the above settings are OK, click "Convert" button to start converting your videos to SWF files in batches. You can pause, resume, or stop during the conversion process.

If the output SWF file exceeds 16000 frames (the frame limit on SWF file), This SWF Converter will auto-split it into several parts to avoid the halt during SWF file playback.
