hi, I need to convert my flash .swf to .flv files for my website. I tried iwisoft swf to video converter. Though the output video and audio quality is very good, it always has a logo mark on the left of the output video. need $49!!

I wonder if you know any good freeware can do the .swf to .flv conversion. And the output flv video can be published to website. Thanks.

Quick, practical update for anyone who finds this old thread: Flash/SWF workflows changed a lot after 2020. Adobe officially ended Flash Player support on December 31, 2020, and browser support was removed, so relying on FLV/Flash playback on the web is no longer a safe choice. Converting to MP4 or WebM for web delivery is the modern, compatible path. (adobe.com)

Which tool/approach to use depends on what’s inside the SWF. If the SWF simply contains a video/audio stream, extract that stream and transcode it; use SWFTools’ swfextract to pull embedded media, then transcode with FFmpeg (lossy or lossless) to MP4/WebM. Example workflow:

# extract media (example)
swfextract file.swf

# transcode extracted stream to MP4
ffmpeg -i extracted.flv -c:v libx264 -crf 18 -preset medium -c:a aac -b:a 192k output.mp4

FFmpeg and SWFTools are well-suited for this kind of job, but note that many SWFs do not contain a discrete video stream — they are timeline/vector animations or interactive apps. (directory.fsf.org)

For timeline animations (frame-by-frame Flash cartoons) there’s a free, purpose-built converter that many animators use to produce high-quality MP4s with frame-consistent output; it’s a good first stop if your SWF is an animation rather than a packaged video. If the SWF is interactive (requires clicks, user input, or ActionScript), try running it in an emulator/player (Ruffle) and record the playback—some SWFs must be captured rather than auto-converted. (github.com)

Notes and troubleshooting: keep the original SWF, test the converted file on phones and desktop, and beware of watermarks/trial limits with many GUI converters. If you have the original FLA/project file (as hinted), export from the authoring tool for highest quality. For and others: converting to FLV today is generally discouraged; aim for MP4/WebM for broad compatibility.

There is no freeware for converting .swf to .flv.

But there is a website do the conversion online, try the following link:

Another Method from your flash cs4 itself:

Open your source flash file
Export movie as quicktime
Then convert the quicktime movie to flv using flash encoder

Please reply after you tested.
