flv trimmer?

[InuYasha]

While trying to download a flash video file it cut off before it was finished and now the video only plays for like 3 mins before it stops,basically I want to find a program that doesn't have any silly time limits to trim off the end of the file to see if I can save the file,and yes I know the best option would be to redownload it but I want to try and avoid that if I can...

I can fix AVI, I can fix DVD and I can fix WMV/ASF and I could probably find out how to do MKV (it has never really come up) but FLV is a new one for me.

Being a streamed format FLV should be a bit more able to be pulled about though. Trouble is a search for flv splitter is going to be filled with the actual tool known as a splitter (the thing that takes the video file and sends audio where it needs to go, video where it needs to go and subs where they need to go).
That said http://www.moitah.net/ (FLV Extract) claims to have a lot of functionality and most of the time breaking it down to raw streams and building it back up does wonders. Once you have extracted it you will need to feed it back into a proper container (very little handles raw streams), most seem to suggest MP4 ( http://www.videohelp.com/tools/YAMB - do not use the uninstaller on later versions of windows) though MKV ( http://www.bunkus.org/videotools/mkvtoolnix/ ) might also be an idea.

Your best bet is to use mkvtoolnix. Basically find out at what time does the video stops, then use mmg (GUI of mkvmerge inside mkvtoolnix) to remux .flv into .mkv with specified cutoff time + aspect ratio + FPS.

Problem with MP4 container is that they only support H.264 + AAC / ALS. FLV can contain a lot of codecs, some which MP4 does not support (which you need to re-encode into supported codecs).
