If the video plays back on your computer without problems then your best option is to re-encode the video and choose different video and audio bit-rates. See the FAQ on how to stop movies jerking.

This is usually to do with the speed of the system used for encoding. Older and those machines with low RAM will have trouble encoding video and will often produce video that falls out of sync. The power of the playback machine is also a factor. The larger the viewable video area, the more resources required for seemless playback. You will need to weigh up the average system of your users with the size of the video that you provide, or look to offer multiple sizes.

There have been numerous reports of "lip sync" problems, where the audio lags slightly behind the video, and even reports of the audio coming before the video. Perception of a sync problem is highly subjective--some people are bothered by it while others can't discern it at all.

The synchronization result of video and audio is highly depend on the computer performance. Please quit all other programs including any background jobs during conversion.

It is quite possible your phone requires different settings with what we offered or you set. Please get to know more about what proper settings for frame rate, as well as some others your phone can support. If the Advance button is disabled, after you click Audio tab and please click Volume button in Sound Recording panel and then you will see a pop-up window, and choose Properties in Options menu and then please check Stereo Mix in the list.

If you have burned the result to DVD, see if the result of the converted file (before it was burned to DVD) has the same synchronization problems in order to make sure that the audio problems are not due to bad media. You may have to redo the conversion with the option "Burn result to DVD" and/or "Delete folder after successful burn" unchecked (in settings under "Burning" tab). Use the latest version of VLC (www.videolan.org) to watch the result.

Flash SWF video has two framerates: a) a video framerate, which is the number of distinct video frames per second in your video, and b) a SWF framerate, which is the number of SWF frames in your final Flash video. These are not the same thing and you have to keep track of both - and how they relate to each other and to the source video framerate. Flash video is different in this way then standard video which has only a single video framerate. (Note: This does not apply to FLV video.

Some computers cannot display video unless they are in 24- or 32-bit color mode. To see if you are in this mode right-click on your desktop and choose 'Properties' then click the 'Settings' tab.
