There are few things more aggravating than trying to watch a video whose audio is about one second too slow. Here's a quick fix for the problem in VLC. In a previous post I wrote about, but since then I have received few complains of ‘Avidemux’ not being able to fix those issues in some cases. Samsung kies alternative for mac. Now to be honest, I too have come across some of these problems but fortunately I have been able to fix them (so far). ‘Avidemux’ can do very little if the input file itself has some issues (corrupted video frames etc) but ‘Avidemux’ is also a bit buggy, so some of the blame goes toward it also. Download for mac os x. You can “test” it as long as you want. In any case, there are few other tools that you can try while trying to fix a sync ‘malfunction’, and ‘MKVToolNix’ is one among them. Illustration ‘MKVToolNix’ is not an encoder as you can only use it to ‘extract’ audio/video/subtitle tracks from other containers (MP4, AVI, FLV etc) and put them into the powerful and open-source MKV container. While doing so this tools also lets you pass certain settings (sync,, aspect ratio ) and it is through that we can attempt to fix sync problems. But please be aware that the only output format it support is MKV (and few of its variations such as ‘MKA’ for audio’, ‘MKS’ for subtitles etc) and unlike MP4 or AVI, MKV is not supported by a lot of commercial and strictly hardware based multimedia players. Computer users however do not have to worry about it as popular players (VLC, MPC,, SMPlayer, KMPlayer ) support it. Enough talking, let’s do it! Note: Make sure you have downloaded and installed the latest builds of ‘MKVToolNix’ from. I also recommend that you use VLC because both these utilities are available for multiple operating system platforms, so you can use this ‘guide’ in any of them. What we are going to do is *. First we are going to play the ‘troublesome’ file in VLC (or any other player that lets you change the sync temporarily) and we will try to identify the proper sync value. Then we will simply enter that sync value into ‘MKVToolNix’ and save it as a new MKV file so that it is saved permanently. Microsoft word for mac. ![]() ![]() Step 1: So open your ‘troublesome’ file in VLC, and let it play for a few seconds. Then simply press the ‘j’ key on your keyboard. This will make VLC play the audio track a bit ahead of the video. A single click increases the value by 50 milliseconds only, so unless the ‘gap’ is very small, you will have to press it a few times to get see its effect. Anyhow, if after pressing ‘j’ key for a few times it worsens the ‘gap’, then it is an indication that you actually have to make VLC play the audio track a bit behind (delay) the video. The shortcut key for that is ‘k’. Again, to feel its effect, you might have to press it a few times. If after doing that it seems to shorten the ‘gap’ then it is an indication that you are on the right track. So keep doing that until you come up with the perfect sync value. So as a general rule, play with ‘j’ and ‘k’ keys, until you find the perfect sync value for that multimedia file. Once you have found it, simply take a note of it (note that depending on the file the value could be positive or a negative one. If it is a negative/minus one, then you should enter a minus sign before entering the value in ‘MKVToolNix’, more below) and close VLC. Step 2: Now open ‘MKVToolNix’ and load the ‘troublesome’ file into it.
