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.
The Macromedia FLV file format lets you import a static video stream with encoded audio.
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.
This will depend on the video codec you use to encode the video. The MX Video codec requires at least Flash 6 (MX). The Screen Video codec requires at least Flash 7 (MX2004).
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.
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.
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.
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.
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.
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.
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.
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.
