I do remember seeing an FLV video editor out there somewhere. Check out "Boilsoft". Google hard my friend.
But If you convert the FLV to Mpeg 2 video, MP2,/AC3 audio, it should import into any video editor. Even my old Sony Screenblast Movie Studio 3.0, Windows Movie Maker, Arcsoft Showbiz, will open mpeg2 video, MP2 audio. My old versions Windows Movie maker, Arcsoft Showbiz, Nerovision 3, will all open AC3 or MP2, so your video editor (Cyberlink) should. Just convert the FLV to Mpeg2. *
There's a few different ways I fix A/V sync problems. I (demux) separate audio from video (Mpeg2) with Projectx, then open the audio in Audacity 1.3 or soundforge and do a time stretch, or change tempo to make the length of the audio match the length of the video. That's if the audio starts in sync, then gradually goes out of sync.
or method 2 (if the A/V sync is off the same amount throughout the whole video)
I Demux the MPEG 2 and open the M2V, MP2, or AC3, in Mpeg2schnitt. (it won't open Wav) You can adjust the audio to move it forward or backwards to match the video. I think 1000 ms = 1 second. Mpeg2schnitt will then create another M2V,MP2/AC3 file thet can be remuxed with Avidmux.
Avidemux will also shift the audio, on the left there is a checkbox for "Shift" and a field to type in your ms. type a minus "-" to shift the other way. (ex -1000) I can't comment on how well it works in Avidemux, but it works great in Mpeg2schnitt.
* If you can't find anything free that will open FLV or convert FLV to MPEG2.
Here's a free bassackwards work around for getting FLV to open in a video editor.
As a last resort.
hang on 'cause it gets crazy. It may not work for all FLV's like Sorensons not sure.
You'll need DVDstyler.
Use DVDstyler to convert the FLV to VIDEO_TS folder. Then import the .VOB video files in your favorite video editor.
Dvdstyler will convert most FLV to either NTSC or Pal DVD.
DVDstyler isn't hard to use, once you get used to it. Sadly, I don't have time to give a full tutorial, but you should get the idea.
(From memory) Drag the FLV's into DVDstylers timeline, They are now called "Titles" right click the Title, choose properties, you can change the audio to either AC3, or MP2, you can change the video to pal, or ntsc. if your video editor won't open AC3, it might open MP2.
create a simple menu. drag and drop a button onto the blank background, right click the button choose properties, and tic the "play all titles" check box. click the burn button. Have it generate a VIDEO_TS folder by ticking the "just Generate" box. choose a destination. DVDstyler will convert the FLV's to MPEG2, AC3 or MP2 VIDEO_TS folder on your Hard drive. Normally I wouldn't recommend having your Author convert files, but DVDstyler doesn't do a bad job with FLV. If all you want to do is burn the FLV to DVD without editing, just drag the TS folder into IMGburn and you're done.
If you want to edit it in your video editor, read on.
Now find and open the VIDEO_TS folder, find the .VOB video files. They'll be named VTS_01_1.VOB, VTS_01_2.VOB etc. all but the last one will be 0.99 GB.
The VTS_01_0.VOB is the menu, you don't need that one.
Import those VOB's into your video editor.
If your video editor supports AC3, MP2, but is struggling with the VOB elementary streams, try this.
DL PVAstrumento add the VOB's. click "make a PS". Name your video and add the .mpg extension. this will change the VOB from an elementary stream to a program stream. This should open in your video editor. It'll open in Windows Movie Maker, Arcsoft Showbiz, Nerovision, actually Nerovision does a great job opening and merging VOB's on it's own.
If your Video editor won't recognize AC3, MP2 you'll have to convert the audio to Wav. ( I hate to do it 'cause you really lose audio quality)
