editing VOB files

Step 1 – Copy VOB File:
Your first task is to copy the .vob file from the DVD to your hard drive. Find your .vob files, they are usually in the VIDEO_TS folder of our DVD. You can’t rename the .vob file on a DVD because DVDs are read only, so copy the .vob file from the DVD to your hard drive.

Step 2 – Rename VOB File To MPEG:
Windows Users (Right-Click)
Right click the .vob file on your hard drive and choose Rename from the menu. Rename VTS_01.vob to VTS_01.mpeg.

Step 3 – Import & Edit MPEG Video File:
Import the file into a video editing application, such as Premiere Essentials, Premiere Pro, Windows Movie Maker or iMovie. Once the file is imported, drag the video file from the project panel to the timeline. If you have multiple files, place them in the desired order, creating a sequence of clips and events, which play in the timeline from left to right. When you have finished editing the timeline, you can play it back in real time or export it in a variety of formats.

Free video Editor:  

Microsoft Photos

• The successor to Windows Movie Maker is easy and fun to use
• Very simple to use
• Pre-installed with Windows 10
• Good choice of filters and effects
• No multi-track timeline

The Fall Creators Update brought many fun and useful new features to Windows 10, including a video editor that's a direct replacement for Windows Movie Maker. Interestingly, it's tucked away in the Microsoft Photos app, but it's easy to use and very accessible for beginners.

Start by choosing your media files (photos and video) and arranging them in a sequence. You can then make some simple edits (like trimming video clips and applying filters), apply fun motion effects and titles, and set the whole thing to a lively soundtrack.
You don't get quite as much granular control as you did in Windows Movie Maker (you don't have separate tracks for video and audio, for example). but the effects and transitions are vastly improved, and it's much easier for a complete beginner to achieve good-looking effects. Once you're done, you can save the video to your PC or share it straight via Skype, YouTube or OneNote. You won't find a more direct replacement for Windows Movie Maker
