How to Merge Audio with Video Synchronously Without Lag?

When merging the image and sound of a video asynchronously, there will be an unpleasant audio-visual experience. It seems like you are watching a lip-sync show. Users of Adobe Premiere, Final Cut Pro X may have faced with this out-of-sync problem when they merge audio with a video.

For example, Adobe users are troubled by the audio track lagging 500 seconds later than the video track, and the unpleasant watching experience drives them crazy. But Adobe users are not alone. Final Cut Pro X users are frustrated that if they set the output format bigger than 20MB, the same out-of-sync problem occurs.

Some possible factors are found to be responsible for the out-of-sync matter:

First, you may happen to pick up the less recommended output format, eg. .avi, .mkv, which are able to play smoothly only with typical media players.

Second, the dissonant image and sound are impacted by the frame rate and the code rate. And sometimes this may be attributed to the media players.

Third, the variable frame rate can cause this A/V out-of-sync issue. Many Adobe Premiere users have encountered this problem, and they get it solved by converting the frame rate.

Is there any software that can settle this problem? Here we would like to recommend VideoProc, which can guarantee A/V sync when joining videos together and can fix out-of-step media file.
