Fix an old FLV file that won't play.
Old FLV (Flash Video) files often won't open in modern players because Flash was retired at the end of 2020 and the format was left behind. When the video data is still inside the file, FileFix may be able to rebuild it into a file that plays today — upload it and we'll show you a free preview first, and you only pay if it worked.

Try another fileGood news — your file isn't damaged. No charge.
There's nothing to repair. If it still looks broken, the issue may be the player, codec, or viewer on your device rather than the file itself.
We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
Unrepaired files are kept encrypted for up to 30 days, then deleted.

Why old FLV files stop playing
FLV (Flash Video) was the container behind most web video from roughly 2005 to 2015 — early YouTube and Vimeo clips, webcam captures, screen recordings, and streamed-then-saved video. When Adobe retired Flash at the end of 2020, browsers and most modern players dropped FLV support, so a file that opened fine for years now shows an error or a black screen.
Some FLV files also never finished writing in the first place: a screen recorder that crashed, a stream capture that cut off, or an interrupted download can leave the video data present but the small structural index a player needs to open it missing or incomplete.
In both cases the footage is often still inside the file. FileFix reads what was written, attempts to rebuild the missing structure, and produces a file that today's players can open. You watch a free watermarked preview and see exactly how much came back before paying anything.
Two honest limits: if the recorder stopped so early that little real video was written, there may be too little to rebuild. And a 0-byte file has nothing inside to recover. In either case we tell you and don't charge.
