If it’s hardware based, you should be looking elsewhere. But this method that I’m going to show you, only works if the sync problem lies with the multimedia file. Sometimes syncing issues are also caused by audio hardware devices (sound cards, amplifiers or even buggy headphones etc). This is a pretty common issue in multimedia files and there are many reasons behind its existence, but for keeping the article clear and simple so that anyone can understand its context without having to go through boring technical details, I will not mention them. If the synchronization value is incorrect, then the audio (or the video) is going to be played early or with a delay, compared to the other, which is commonly known as ‘lip-sync’ errors, and it jeopardizes all the excitement, obviously.įor instance, while watching a movie, if you have ever come across situations like gunshot firing sounds coming out before its video scene is displayed, then that is due to an improper audio to video sync. If you're looking for a free and easy-to-use video compression and editing program, don't hesitate to download Avidemux.‘ Audio to video synchronization‘ is an extremely important aspect of a multimedia file, because when playing, multimedia players rely on it for properly synchronizing the audio and the video tracks.

Plus, with the artistic filters available on Avidemux, you can make a video look like it was recorded on VHS or replace a green chroma key with the image you want in the background. For example, you can add logos, change the frames per second, crop, recompress to fit a specific size, stabilize the image, add subtitles, reduce noise, add detail, apply a color profile using LUT, and much more. In addition to compressing videos using a more efficient codec, Avidemux also allows you to use filters to modify the content. In the case of audio, you can compress to all kinds of formats, such as AAC, AC3, and MP3, among many others.Īmong the most basic video adjustments, you can trim content to remove unwanted parts, as well as correct the synchronization between video and audio. Thanks to the use of these codecs, you can reduce the size of any video.

This open source application is capable of encoding videos in the most widespread codecs, including MPEG-2 (with libavcodec), MPEG-4/H.264 (with x264), and HEVC/H.265 (with x265). Avidemux is a program for compressing and trimming video and audio, as well as adding effects.
