Unfortunately not all conversions go 100% smoothly and some result in audio and video
synchronization. This may be due to many reasons, the main problem is the original film source
and software / codec conflicts. Here we will tell you how to solve these problems with a few clicks
Tools needed :. Womble MPEG Video Wizard DVD
This software includes three tools ( three methods ) to solve the audio / video sync your problem
a ). MPEG GOP Fixer
This tool allows you to check and correct the mistakes of GOP timecode, audio and video PTS (presentation hours)
error and DVD size violations GOP, which may be contained in a data file MPEG.
1 Click on the toolbar and select MPEG GOP Fixer Tools drop-down list.
2 In the Open dialog, your MPEG file input is problematic.
3 So in “Test Options”, choose a solution with your file. eg “Fix time GOP
code and PTS errors (read + write)” and then click “Start”. GOP Fixer will automatically scan your MPEG
files and correct errors
b). MPEG MBS Scanner
This may sound happen / video synchronization problem when an MPEG file that contains the following three changes:
change the timebase, which a time code restarts;
video encoder settings change, such as image size, frame rate, and rate bit? and
sound can change the codec settings, such as sample rate, bit rate and number of audio channels
. We refer to this type of file as the Multiple Bit Stream (MBS) MPEG files. When this happens, we can solve this
a / v sync problems using MPEG MBS Scanner.
1 To open the MPEG MBS scanner, click the Toolbar and select MPEG MBS scanner from the list.
2 In the open dialog box, enter your problematic file MPEG, and then click the Search button to start finding
error.
3 After completion of the scanner, you can add the file list section on the timeline or
project manager for further processing. eg “Add to Timeline”.
4 Export to file a new MPEG
c). MPEG demuxer
Use this tool to split an MPEG stream file systems in a number of elementary streams (video-only and audio-only
streams). It is very effective in helping you solve your audio / video sync problem, as is often
encountered in MPEG files with time code errors.
1 Click Tools on the toolbar and select the MPEG demultiplexer in the dropdown.
2 In the open dialog, input MPEG file, and you select “Create New Project
Timeline in output files” for further processing.
3 Split MPEG file into separate audio and video files by clicking the “Save”. The separate
Video (. MPV) and audio (. Mpa) will automatically be imported to the schedule after the procedure demuxing
.
4 Adjust the relative delay between audio and video, for initiating or video or audio clips,
be in sync.
5th Save the resulting file to a new MPEG.
