conversion programs just won't work!

[Sean O'Scare]

I simply cannot find a video converter that will convert flv videos to avis without a problem and it could be attributed to problems with my computer, but I have used online converters like vixy.net and the same problems have occured.

The first FLV converter I used was the Batch FLV Converter and it used to work perfectly. It didn't convert to avis with sound oddly, but I could resynch the video and audio tracks in movie maker. Now for some reason when I convert flvs now, only a certain percentage of the video will be converted, such as 6:11 or even less, and this will remain the same for all videos longer than that length that I convert during that particular session. The only tell tale sign that something wasn't quite right with the program was the incredibly long time it took to convert one single video.

The current one I have tried using is Total Video Converter, and for the first time I was able to convert flv videos to avi using the mpeg4 codec successfully and I could even import them into movie maker without problems too. However, this program is now playing up on me too. It converts incredibly large files that come with the audio track in tact, but it freezes at either the first frame or at any point i click on the clip. If someone could provide some useful advice on this matter it would be most appreciated.

Try convert to some other video codec in total video converter. I don't know what you can select but try different and see if it works better. You can also convert to wmv and you should be able to import in wmm.

Or try convert the FLV with SUPER or WinFF.

I use..... WinAVIVideoConverter...... to convert from FLV to DVD and works OK.

You also have the option to convert to AVI as well.

Also does batch conversions

I did 12 in one go....

Hope this helps you.

Hi, newbie here with a similar problem. I have been trying to convert a large flv file to
avi for weeks. I have tried every program out there, I'm sure. It converts but when it
does the sync is off. For instance, I used ConvertXtoDVD and the picture is near perfect
but the audio isn't in sync with the video.

Here are the specs of the file:

Audio: MPEG2 Layer 3 (CBR 32 kbps, 1 cn, 22050HZ, 9.37 mbyte
Video: FOURCC: FLV1 (1.28 mbps, 301 mb. 00:32:52.733

Is there anyone who can tell me how to convert this without losing video
quality and keeping audio in sync? I would be eternally grateful!! My sanity
is at stake here. There must be a way to do this.

Have you tried FLV Extract? That should demux an AVI video stream from the FLV, and the MP3 audio stream. All you'll need to do is mux the AVI and the MP3 together.
(Note that the AVI will still be compressed using the FLV1 codec, so you'll need to have a codec capable of decoding FLV1 streams installed, like ffdshow. Other than that, it should work fine.)

I use SUPER on all the flv i get from youtube, i just convert to mp4 with mpeg4 codec, acc audio or audio stream copy

sometimes avi with mpeg4 codec, specifically mpv4

but most of those files are 12 min or less

You might also give this a try : https://forum.videohelp.com/topic343157.html

AlltoAVI also seems to work fine, at least for me.

However :

If nothing works on a single file, then the file is at fault and should be tossed.

If nothing works on multiple files the you have serious system problems and it may be time for a format and rebuild.

It looks like all the files are doing the same thing. They are out of sync. When I use AlltoAvi
it only records a small portion and then stops.

How do I format and rebuild? I guess that's my only option. Thanks.

Ai Haibara: Thanks. I tried FLV Extract but when I use AVI Mux
it's still out of sync.

theewizard: Thanks also. I am downloading SUPER now but honestly
I think there must be something wrong with my system because
no file I try converts properly.

[guns1inger]

Are they out of sync by the same amount the whole way through, or do they drift out over the running time of the clip ?

Are you trying to convert framerates (say, 25 -> 29.97) etc.

No. I leave it as it is. It's strange because I adjusted the mp3 length in
sound forge to match the length of the video and I then I tried to put
them together in avi mux and that didn't work either. It's still the same.
Does it make any sense what I did with sound forge? I have Sony Vegas
too. Shouldn't I be able to get the avi and audio in sync using Vegas
and Sound Forge?

This is what I get now. The picture is all distorted:

That's odd. The FLV Extract > remux process normally shouldn't introduce any sync problems, as you're just extracting the streams of the original file and then gluing them back together, again. No conversion involved. I'd wonder if AVI-Mux was doing something to cause the sync problem, but it shouldn't.

If you still have the files you extracted using FLV Extract, do the running times of the AVI and MP3 match?

Do the converted AVI files play properly if you use a player that doesn't depend on the codecs or DirectShow filters installed on the system, like VLC or mplayer?

[lyekka790]

No, they are different. The video runtime is 32:52 mins. and the audio is 40:56 mins.

I played the converted avi file in VLC and it was still out of sync. But when I play it, say, on
NERO SHOWTIME, the picture is distorted (see link below) but it's in sync. Very strange.

I had trouble converting flv to avi as well.
I tried exporting from Flash CS3 (lost audio).
I tried RIVA (error messages).
I looked at Super (too complicated).

WinFF worked like a charm!
It converts to lots of standard formats.

[theewizard]

are these files FLV or swf

for swf files I have benn using a prgram called swf to video

from bytescout software

you can get a fully functioning 45 day trial DL from their website

also most FLV off youtube is 25fps and 320*240

when converting to avi in super, I keep the 320x240 RES and set 25 FPS and use mpeg4 codec, mp4 output ext, and set the video bitrate at between 240-576

all this helps keep the audio & video in sync

when super little window pops up with (4) choices for the codec, i choose mp4v

I don't alter the size of the video RES until the next operation

most of my youtube stuff ends up on portable devices like cellphones ( mine ) or ipods ( friends ) so i'm not leaving it in avi or converting to DVD

Thanks. I tried it and it's good but it's still out of sync.

It's an FLV file. But now I managed to get the converted
avi in sync but it sounds like chipmunks! When I change
the pitch, the file is bigger and goes out of sync again.
So now I have the choice between an out of sync file or
one that's in sync but the voices sound like chipmunks!
