RichFLV: free tool to merge, cut, and manipulate FLV video

RichFLV is a free Adobe Air tool that performs a number of operations on FLV video files, including merging files, extracting sections from larger FLVs, exporting audio as FLV or MP3, converting to SWF, extracting individual frames to image files, and defining cue-points and metadata.

Operations can be performed on the whole video or user-defined sub-sections.

If you’ve been looking for a tool that can work with FLV video (merge, cut, demux, edit) this may be the one you were waiting for.

What is interesting about this tool, aside from being FLV-specific is that it can handle (read/write) FLV without the need to install any external codec packs on your system.

Here are some notes on what this Adobe Air application can do:

  • Merge FLV: do this by first opening a file then from the import menu select FLV (stitch) and select the next FLV in line. Save the combined file and repeat for any subsequent files (note: use a new filename everytime; do not save over a file you are merging). Unfortunately it does not seem possible to simply select multiple files simultaneously in one fell swoop.
  • Cutting sections from an FLV’s: this is extremely simple; all you have to do is define the inpoint and outpoints (by dragging and dropping these visually or from the keyframes section), and saving it from the “export” menu.
  • Export to audio or SWF: once you set the inpoint and outpoint, this can be perfomed from the export menu. Your audio file can be either in FLV format or MP3.
  • Cue points: you can define “cue points” on your video, and add informational “parameters” to these. These can be saved within the video itself or exported to XML files. Having said that, I am unsure as to what the usefulness of this is in practice (somebody please advise).
  • Performance: excellent. Saving and exporting is ultra fast.
  • Metadata: you can define your own labels and values and store them in the video. Again, not sure why you would do that, as standalone players other than RichFLV do not seem to read or display the metadata.
  • Memory consumption: is completely out of whack in that it consumes way too much, depending on the size of the FLV file you are working with (e.g. was using 120 megs when editing a 6a0 meg video). This is due to this software being beta and the developer is aware of this and working on it. Let’s hope it improves with subsequent versions; in the meanwhile if you do not use RichFLV as your main FLV player and only launch it when you need it you should be OK.
  • Interface: warrants a mention. Very good looking, provides a nice user experience. The information and control panels can be minimized at will. Only criticism: no drag and drop support.
  • Keyframes section: seems to be there entirely for navigational purposes.

Wish list (or how this program can be even better)

  • Merging multiple FLVs at once: honestly with a program like this it should be possible to specify a number of FLVs, sort and/or organize them, and merge them all without having to go through the dance described in the “Merge FLV” section above.
  • Splitting an FLV: somewhat baffled that it is not possible to use the cue points I set to split the FLV. This program needs the addition of rules-based splitting (e.g. every 10 mins, x number of equal parts, etc.) as well as the option to use user defined cue point for splitting.

The verdict: overall a nice tool especially given the dearth of free tools that edit/manipulate FLVs. If you need to merge FLVs occasionally, extract video segments, audio or image stills from them or convert them to SWF this is probably the tool you are looking for. Otherwise check out the following tools: FLV Extract, Flash This!, Avidemux, Movica (these last two being generic video editors that can handle FLVs if you have appropriate filters/codecs installed on your system). My favorite video converter SUPER can also split FLVs – see this thread.

Also bear in mind that this is beta software and that as the author takes it to the next level it will continue to improve (keeping my fingers crossed that he will take my wish list items above into consideration).

    Not your fault, but I don’t like being told I MUST install Adobe AIR to run RichFLV – Adobe are notorious megabloat merchants. So I’ll pass, thanks. Micro$oft can stick Silverlight, too.

    disappointing i thought i could cut scenes

  • GYUT

    This is not what it claims to be!

    It doesn’t allow dynamic user-defined start and end cut points. It keeps “sticking” to pre-defined keyframe inpoints and outpoints.

    The splitting of flv files doesn’t work properly. From over 100 attemps to split a flv file( and different ones) I had just ONE successful attempt. I tried to pre-install the program again and again on my computer but it was the same picture. Really frustrating…

    Thank, but i think you can Moyea FLV Editor Lite for free,which most important is that its editor funcations with timeline and no-codec for video output,really easy to use .

    RichFLV has a very slick-looking interface, but it appears that quite a lot of development work still needs to be done before it can be regarded as reliable.

    I tried it on my Mac Pro 3.1 under Snow Leopard 10.6.8. I used the “Merge FLV” procedure described above to stitch together two .flv files. Alas, the end result was not good.

    The two originals were encoded at 256kbps, 15fps and a frame size of 240×320. When I played back the output file (I tried it in several media players), I found that it ran too fast, had chopped-up audio and reported its duration incorrectly (27 minutes long when in fact the duration should have been around 45 minutes). When I investigated the stream info using MPEG Streamclip, it reported that the bitrate was 448kbps and the frame rate 25fps.

    I don’t think that the actual bitrate and frame rate had been altered at all. I suspect that the header information in the output file was incorrect, causing the media players to attempt to run it at 25fps instead of 15fps.

    So for now, I’ve uninstalled RichFLV. Until it improves, or a more reliable flv-joiner for Mac OSX comes along, I’ll go back to using “flvbindgui” under Windows – at least that’s stable and reliable!

    great post ..I like this site

  • Jeff

    Great program. It is easy to use. You may merge two flv files together. That is exactly what I wanted. Bless you!!!

  • rj-disappointed

    does not work… seriously a waste of time… :(

  • everyman

    Why is it so damn hard to find the right downlind link on this site??????

  • Marty

    This tool doesn’t work for me. I opened an FLV (worked), I imported an XML Cuepoint Sheet (Worked), I clicked Save As, [Filename], ok (Sat there at Saving File…Never ended even after 8hrs). Tried again, this time using export, same thing.

  • Marty

    Just a not to add extra info. It seem that it DOES work, however, won’t create files above 256Mb in size. It’ll happily load files greater than this limit, but hangs saving them.

  • Anna

    Worst attempt ever. Every attempt to save a segment of the video resulted in unplayable format. Don’t even waste your time.
