A/V Sync on only some FLVs

[RedPenguin]

I'm using this guide:

http://www.digital-digest.com/articles/FLV_to_AVI_Conversion_Guide_page1.html

I had to skip the part about not interleaving the a/v because then it wouldn't play in my DivX DVD player.

Also I had to go VirtualDubMod's Video -> Frame Radio -> Option to have A/V Synced under Source Adjustment

Now this made perfect Xvid AVI's from about 12-15 FLVs but there are just 3 that will just not get A/V synced in this manor.

All 3 seem to have the sound before the video.

The original videos match up in FLV player.

Try convert with WinFF instead.

Or...

Try latest VirtualDub + FLV input plugin.

[RedPenguin]

Well WinFF seems to do the same as I said in the first post and the FLV Input Plugin seems to almost get the A/V synced but not completely on key.

You hear people talking before they even move their lips.

[Placio74]

Well...

Upload some problematic FLV clip on kotuha.com.
Or if it's downloaded, show link to source.

How can I take just a fraction of the FLV?

How can I take just a fraction of the FLV?

Possible (Movica, Avidemux), but not perfect.
However, better 'show' some untouched clip.

BTW
If can play FLV's in DirectShow, can use Avisynth script or VD with DirectShow input plugin.

have you tried SUPER, thats what i use for flv to avi, then import the avi into vdub

[RedPenguin]

I found out the file is VFR and that it's FLV4.

Does this make a lot of difference or no?

Yes.

[RedPenguin]

Is there any software that will defiantly read the timestamp file that FLV Extract outputs?

I figure if something will read that, then maybe it will be gold and no more A/V sync.

EDIT: Here is a piece of my FLV file finally:

EDIT: I just converted just that chuck like I normally do, and it's weird, that peace has no A/V sync error. Why would the whole thing have one then?

[Placio74]

VirtualDub 1.8.1 + DirectShow input plugin 0.5
Open video file... - choose file and change file type to DirectShow input driver.
When i'm try result is good (A/V sync).
(Required FLV Splitter and ffdshow (with active VP6F support).)

------

Avisynth script > VirtualDub
Example script:

DirectShowSource("d:\path\t---S01E03---All-That-Glitters_part002_part002.flv",fps=25,convertfps=true)

When i'm try result is good (A/V sync).
(Required FLV Splitter and ffdshow (with active VP6F support).)

------

FFmpeg / MEncoder (and of course some GUI's) - can't determine FPS in this file.
Useless for this sample file.

------

VirtualDub 1.8.1 + FLV input plugin 1.1.0
Unfortunately - 'out of sync' A/V.
(Even with Change so video and audio durations match and Convert to fps.)

Thank you, Thank you! Except for strange sounding audio.

Now the audio makes weird stuff like, noises, echos, etc.

[RedPenguin]

I tried to even play on another machine, but the audio still seems scratchy and it makes funny noises like someone going errrrrrrrr. It happens about every 60 seconds or so.

You hear the same sounds playing the FLV in Windows Media Player, but not in FLV Player.

I installed FLV Splitter and FFDShow. The audio is mp3. I tried both libmad and mp3lib.

It sounds like a drill or a zzzzzzzz sound every now and then.
