I could use some help with using VLC Media Player. I have tried to convert.avi files to.mp4 files using VLC. The conversion proceeds normally with excellent compression and image result. However the sound is missing. I've done a Google search and see this issue listed, but the solutions are vague or not applicable. I can convert to MP4 and get the audio track but no video. Or I can convert to MP4 and get the video (although vertically squashed well beyond letterbox) and no audio. Is there some magic configuration that actually works? I have always found VLC to be fiddly and have a user interface that is pretty different from conventional Mac/Windows UI. VLC Convert MKV to MP4 no Video (there is audio) Date October 17, 2016 Author Catherine Category Alternatives, MKV, Video Tips, VLC. VLC is a media player but also a tool people often use to convert videos. Things are that there are some questions in forums that when people convert MKV to MP4 with VLC, many get audio only without video. VLC play them without problems, but when I load the file either in the Windows video editor, or in Power director 13, the video play but there is no audio. I am not sure why I can't even convert the file from VLC, since even using the conversion engine that is integrated in VLC, the resulting file has video but no audio.
Tip 1. Unmute Audio in VLC Media Player
It might be due to a configuration error, which can happen in an instance that you just muted your video player by accident. In this image, the sound is being muted. Please make sure the sound is not being muted by checking 'Audio-Mute' in VLC.
Tip 2. Update VLC to the Latest Version
The VLC has no sound problem may be caused by an outdated VLC version, which you can fix it by upgrading to the latest VLC version to get the latest program enhancement that lacks on your previous version. VLC is also a free and open source product. In the latest version of VLC, open source programmers may fix some of the sound bugs or add some new audio codec into it.

Open VLC Media Player and click on 'Tools-Preferences'.
Switch to 'Audio'. At the bottom, click 'Reset Preferences'.
Tip 4. Adjust VLC Audio Settings in Preferences

Click on 'Tools-Preferences' in VLC.
On the 'Simple Preferences' interface, navigate to 'Audio Settings'. Make sure the 'Enable audio' box is checked and then choose 'DirectX audio output' at Output dropdown list. Actually, if this does not work, you can try all the choices one by one in 'Output module' and 'Device'.
Tip 5. Ticked 'Disable All Enhancements' in Control Panel
Open the control panel on your computer, clicked on the sound option, then disable all enhancements for all devices. After applying, restart VLC to check if everything works fine now.
Tip 6. Convert Video to Another Format
VLC supports so many video and audio formats. However, sometimes you just cannot play the MP4 or MKV format file with sound. How is this possible? One of the reasons for this is, MP4 and MKV are container formats. They can package video, audio in the different codec. However, some of the codecs may not be supported by VLC Media Player.
When encountering this, the easiest way to solve is to convert the video into one of the codecs that will definitely be supported by VLC. And a good video converter can help you do this with just a few clicks. We can find various video converter from the Internet. Here I introduce a powerful yet easy-to-use video converter called VideoSolo Video Converter Ultimate.

No matter you download your favorite videos from online, or get a copy from DVD/Blu-ray discs, you're in a great chance to meet MKV videos. However, not every device or video app can play MKV files, and that's especially true on mobile devices. Therefore, it is often necessary to convert MKV to a more usable format, like MP4 which is widely supported by most devices and apps. In this article, we will show you how to use VLC to convert MKV to MP4 for free in details. If you're experiencing issue with VLC video conversion, you can also check fixes here.

Part 1: How to Free Convert MKV to MP4 using VLC (Step-by-step Guide)
Note: We're using Windows PC for example and screenshots to show you how to change MKV to MP4 with VLC, but the VLC app works pretty much identically on MacOS.
1. Convert from the Media menu
Click on the Media menu in VLC, and then click on Convert / Save.
2. Select MKV video(s) to convert
Using the Add button, select one or more MKV video files to be converted.
3. Select the file name for the converted video
In the Target file box, select the destination folder and the name for the new video file.
4. Select video format for the conversion
Under Profile, choose the target format from the list of formats.
The VLC media player easily converts videos into different formats such as MPEG, MP4, AVI, Divx, ASF, WMV, or DVD. You can see a full list of the video file formats that VLC supports here.
If you want videos for a specific device, there are also a number of optimized profiles with the optimal settings for resolution, framerate, and codec.
Advanced Settings (Optional)
By using the menu with the tools icon, you can change the settings for the destination format to adjust itself.

Here, you can choose the supported video and audio codecs and have access to all advanced options like bit rate, resolution, framerate, and audio quality.
With special filters, you can also change or optimize the video or audio track during the conversion process. For example, you can rotate recorded videos 90° or add a watermark or logo.
5. Conversion: Videos saved in the target format
Once you've chosen all the settings, click Start to begin the conversion. VLC media player saves the film in the desired format in the file folder you've selected. The time to complete the conversion depends on the video length, the settings you have chosen, and the speed of your PC.
With batch conversion, you can watch the progress in the timeline while you play a video.
So, as it turns out, VLC media player isn't only limited to video playback. If you're looking to make the most of the program, try using it to convert videos too.
Part 2: How to Fix: VLC Won't Convert MKV to MP4
VLC is free and open source media player featuring ability to process media files into various supported formats. But its converting feature is limited.
1. MP4 doesn't support certain streams that MKV does. For instance, if you transcode MKV encoded with DTS audio to MP4 while maintaining the existing DTS codec, there will be problematic such as no audio after conversion (DTS is not officially supported in a mp4 container).
2. VLC is unstable. The VideoLan forum indicates that the transcoding in VLC such as MKV video to MP4 conversion is somehow broken in recent builds of VLC and its forum suggests you to use its older version or wait for a fix, with the help of other video processing programs like FFmpeg.
3. VLC requires codec settings for specific formats. If you choose an incompatible stream for a given muxer, VLC may fail. So it isn't easy for beginners.
4. Please navigate to Tools from the main menu, go to Track Synchronization, and modify the Audio track synchronization setting to solve the audio delay problem in VLC.
Drawbacks of VLC Media Player for Video Conversion:
● It does not allow selecting the desired quality and resolution of the output file.
● The conversion speed is very slow.
●Video editing features before conversion are not supported.
● Conversion controls are limited as compared to professional software.
● Conversion quality is not very good when compared to other paid programs and tools.

Final Words:
Since VLC is mainly a media player software that moonlights as a workable video converter, in comparison with those professional converters, VLC has a limited format support and limited format presets. Handbrake does not support 3GP, AVI, DVD, FLV, OGG, WEBM, WMV as output format but FFmpeg supports almost all of those.
