What is a SWF file?

The Macromedia Flash file format (SWF) (pronounced "swiff") delivers vector graphics and animation over the Internet to the Macromedia Flash Player. For more information regarding Flash, please see our General FAQ.

What is a FLV file?

The Macromedia FLV file format lets you import a static video stream with encoded audio.

What version of the Flash Player are the SWF files exported from Video2SWF compatible with?

This will depend on the video codec you use to encode the video. The MX Video codec requires at least Flash 6 for proper playback. The Screen Video codec requires at least Flash 7. If you are publishing Projector files, the Flash Player is not needed, and thus the minimum Flash version is irrelevant.

Flash will not import my video SWF files. Why?

Flash will not import SWFs completely that contain audio, video, and actionscript. If you want to import your Flash video, you should encode the video as a FLV file instead of a SWF.

There isn't any audio when I encode my video. What should I do?

If running Windows, install or re-install the latest QuickTime with the "Recommended" Installation option checked.
If encoding MPEG files, Video2SWF will only encode the video portion of the file. To encode the audio, you will need to convert your mpeg to another file format and then encode in Video2SWF.

After converting, I cannot see any video but I can hear audio. Why is this?

Make sure you have the minimum required Flash player. For MX Video you will need at least Flash 6. For Screen Video you will need at least Flash 7.

What is the maximum video duration that I can encode?

The Flash player imposes a 16,000 maximum frame limit on SWF files. Anything beyond this will not be displayed. So the actual maximum duration will depend on the frame rate used for the SWF file (10fps = ~26 minutes).
Flash FLV files however do not have this 16,000 frame limit.

How can I get around the 16,000 frame limit?

If you are exporting as SWF, you will need to split up the video and chain the SWFs together by adding a End Movie Action which will load in the next SWF file.
If you are exporting as a FLV file , there isn't any 16,000 frame limit.

Why can't I encode my video even though it's on the list of supported formats?

Most likely you do not have the required codec installed. You should also make sure you have the latest QuickTime (Windows and Macintosh) and Window Media Player (Wndows only) installed.

Why isn't my encoded video playing properly?

This can be caused by using conflicting frame rates. The SWF framerate should be equal to or a multiple of the video framerate to prevent problems such as jerky video or loss of audio sync/distortion.

Can I add my own Players to Video2SWF?

Yes, it is possible to create your own custom Players and add them for use in Video2SWF. You will need to use Macromedia's Flash authoring tool and follow our specification for creating Players for Video2SWF.
