 1. Open the video, compare the voice and mouse lip, or subtitle to sync audio/video. If audio is played before video, jump audio backward separately. If audio is played after video, jump audio forward separately.

2. Try several times, you can get a sync point. Add the point to the sync list.

3. It is better to add at least 2 points at the beginning and end of out of sync position of the movie.

4. Then calculate the audio and video's start time and end time with the sync points.

5. Preview the output video. If there is no problem, then start the conversion.

It supports the video formats like avi, wmv, mpg, asf, dat, vcd, mpeg. If extra decoders are installed, it can support more formats such as divx, xvid, dv, mkv, ogm, svcd, dsm, etc. The output video can be WMV or AVI. If you install more multiplexers/muxers, the program can output more video formats. So the program is a video converter also.

 Basic Software:

• Microsoft Windows XP/2003/VISTA

• DirectX 9.0 or later

 Additional Software:

• If the program get the error message "Failed to load wmvcore.dll" when it is launching, please install Windows Media Format Runtime 9.5.

 

How to use: Picture 1 The key steps to sync a video: 1. Click the Open Video button, select a video file. 2. Compare the voice and mouse lip, or subtitle to sync audio/video.  If audio is played before video, click the Audio skip forward button or press the hotkey i. If audio is played after video, click the Audio skip backward button or press the hotkey p. Click the Skip backward button or press the hotkey q to repeat the last scene so that you can correct time shift between audio and video at the same scene more times. Click the Original audio button or press the hotkey o to reset the audio if needed. 3. If you think you have sync audio/video at the position of the movie, click the Add a synchronization point to the list button. It is better to add 2 points at the near beginning and end of out of sync position of the movie. If you want to add the third sync point to the list, it is better in the middle of out of sync position of the movie. 4. Click the Calculate start button to set Video start time or Audio start time automatically. Click the Calculate end button to set Video end time or Audio end time automatically. 5. You may enter Video start time or Audio start time manually. For example, If you think the movie is sync at the beginning, you enter 0 as Video start time or Audio start time, do not use the calculated value from the sync points. If the movie is out of sync from the beginning, it is better to use the calculated value from the sync points. Normally it is better for Video end time and Audio end time to use the calculated value from the sync points. 6. Preview the output video to check if the output is sync. 7. If there is no problem, then click the Convert button to start the conversion.

Control Panel: Open Video: Open a video. Options: Set output options. Skip forward(w): movie skips forward. The default value is 20 seconds. Skip backward(g): movie skips backward. The default value is 10 seconds. Audio skip forward(i): Only audio skip forward, the default value is 0.3 second. the hotkey is i. Audio skip backward(p): Only audio skip backward, the default value is 0.3 second. the hotkey is p. Original audio(o): Reset audio to original position in the movie. Add a synchronization point to the list: If you sync audio and video at the position of movie according to sync lip and voice or subtitle, add the point to the sync list. Edit: Select a sync point in the sync list, edit the video or audio time manually in a dialog box if needed. Delete: Select a sync point in the sync list, delete the point. Clear all: Remove all sync points in the sync list. Save sync list: Save all sync points in the sync list to a *.ini file for the video. Load sync list: Load a sync list file *.ini to the program. Calculate start: Calculate the video and audio start time according to the first 2 sync points. Calculate end: Calculate the video and audio end time according to the last 2 sync points. Preview: Preview the output video Convert: Start the conversion. If all parameters are right, you will get a synced video. Options dialog box is used to select the options of the output clip and play control.   Note: 1. WMV format is recommended as the default output format. You do not need to install any extra encoder. WMV encoder made by Microsoft is stable. 2. When we test many codecs, we notice FFDshow codec can decode a lot of audio and video formats such as divx, xvid, mp3, wmv, wma. But Audio skip forward  and Audio skip backward may not work well when the codec is running (the icon will be at the right bottom of desktop). It is necessary to disable the codec temporarily in  FFDShow Video Decoder Configuration or  FFDShow Audio Decoder Configuration if you have another codec which can decode the audio and video stream.
