Video Audio Sync and FLVs

Are you experiencing video and audio sync problems in your FLV files?

When I tried to place video on the web in the form of FLVs, I saw that converting MPGs into FLVs creates video and audio synchronization problems. Sometimes, the video moves ahead of the audio, and you'll notice that people will start moving their lips before you hear their dialog.

(Yes, pretty much similar to badly dubbed Kung Fu movies, only in reverse.)

The solution: Convert your MPG into AVI first, and then convert the AVI into FLV. Use a frame rate of 29.97 and a video bit rate of about 225 kbps (320 x 240 resolution).

If you're wondering why I didn't work with AVI right from the start, I had to work first with DAT files in a VCD. Those videos had to be trimmed (or split), which meant first converting them into MPG. After they were split (via WMV/MPG Splitter/Joiner software), the MPG chunks were then converted to AVI.

The AVI was then transformed using free FLV producers.

And that will solve your video - audio sync issues with FLV video online. Have fun! :-)
