The VideoLAN Forums

I followed 3-4 video tutorials how to do this. I loaded both VOB files and hit "Convert/Save" and it converted each file to MP4.
Then ran Command Prompt from the files Saved Folder and typed "C:\Program Files\VideoLAN\VLC\vlc.exe" Vts 01.mp4 Vts 01 1.mp4 --sout "gather:std{access=file,dst=finalmerge.mp4} --sout-keep" and hit enter and VLC didn't join the 2 MP4s. What am I doing wrong?

You need to specify the full path of your MP4 files and to put this path in quotation marks, e.g., "C:\Path\To\file.mp4"

I still don't understand what path to specify. I put the 2 mp4 files in the path "This PC > Videos > Video Formats for Testing > Merge Videos VLC".
I went to the files folder and ran Command Prompt and typed exactly what the tutorial said (above).

I read another tutorial and it said this to merge mp4 files in VLC:
- Step 3. Merge videos with command-line feature.
Create a new folder and move all your videos need to be merged to here.
Hold "Shift" and right-click on the new folder.
Select "Open command window here".
Type the following command and press "Enter" to enable VLC to merge your videos.
"vlc_location" file1.mp4 file2.mp4 --sout "#gather:std{access=file,dst=final.mp4}" --sout-keep

I tried this and when I hit "Shift" and right-clicked on the file folder I didn't see any "Open Command Window Here".

(I also tried joining the 2 H264/mp4 files with "OpenShot Video Editor" and there were hundreds of file type options to choose from. (File resolution of each mp4 is 706x478, 29.97 fps ). So I chose "NTSC 720x480 29.97 fps" and it joined the files but the file size came out 50% larger than the original files. Then I tried "WVGA 720x480 29.97 fps" and it did the same thing with 50% larger file size.)

Your files have one or more spaces in their names that's why you must put these names between quotation marks.
"Vts 01.mp4"
"Vts 01 1.mp4"
