Merge Videos in VLC: Resulting Video Not Working and How to Fix It

How to merge multiple videos to a new one in VLC?

VLC is a cross-platform media player. It's compatible with Windows, macOS, Linux, Android, iOS and some others. This guide was carried out on Windows 7.

Step 1: Download VLC.

• Visit VLC download site: videolan.org.
• Choose an edition that matches your operation system.
• Click to download the setup file.

Step 2: Install VLC.

Step 3. Change portrait videos to landscape

You might have found some videos that you recorded from smartphone are in portrait orientation while played back with VLC on computer. In this case, you may need to rotate the portrait video to landscape.

However, the rotation feature in VLC is conceal and not expressed as "Rotate". You need to go to: Tools -> Effects and Filters -> Video Effects -> Geometry -> Tick Transform -> choose your degrees of rotation.

But you can have an easier way to merge your videos >>

Step 4. Convert videos using VLC.

Note: VLC can NOT merge videos unless they are in the same format. If your video clips are encoded in different formats, follow these steps.

• Launch VLC.
• Select "Media" on the main toolbar.
• Click "Open Multiple Files".
• Add video clips by clicking "+ Add" as shown below.

• Unfold the "Play" button and select "Convert".
• Select a profile i.e. Video – H.264 + MP3 (MP4).
• Click "Start" button to run video converting process.

Step 5. Merge videos with command-line feature.

• Rename your (converted) videos as simple as possible, such as 1.mp4.
• Move these videos to a new folder.
• Hold "Shift" and right click on the new folder.
• Select "Open command window here".
• Type the following command and press "Enter".
• VLC will begin merging your videos.

Issues you may come across when you merge or play videos in VLC

Issue 1. VLC cannot set a destination folder for batch conversion.

VLC allows you to do that only when you add a single video. If you added multiple videos, you'll find "Multiple Files Selected" in the destination path and you can do nothing to customize it. If you have 10 or more video clips and want to step away from being tortured by converting them one after another, try the following options:

• Handbrake – convert video to MP4 in batch to a new folder, but you have to switch back to VLC for video merging (It has been verified that merge video feature is unrealizable in Handbrake by its official site.)
• VideoProc – one click solution to convert & merge videos in batch. You can save the newly merged video in whatever format or wherever on local drive as you wish.

Issue 2. The merged video has no image but only sound in VLC

Go and play the source video clips to see if any of them are corrupted. There is also a chance that the video conversion operated by VLC is incomplete or there was a video codec issue but VLC forced itself to complete the conversion. Try playing the merged video using some other media players such as Windows Media Player, KMPlayer, Potlayer, etc.

Since VLC often causes no image or video audio out-of-sync issues when merging videos More people tend to: merge videos with zero problem in 3 steps as follows:

Before we get started, first download and install VideoProc on our PC or Mac computer.

Step 1. Open VideoProc, click "Video" button and then drag & drop your video clips.

Step 2. Click "Target Format", and check "Merge" option. VideoProc also lets you cut, crop, rotate videos and add special effects.

Step 3. Click "RUN" button to convert and merge videos in one shot. Once done, you will have a new video.
