Open up the program. I changed the “Project folder”. Optional, your choice. I put in a project name called “Test”. I’m going to try joining two videos to set how it works out.
I clicked on “Start” then I clicked on “Open File”, top menu. I selected my first video. It was called “part1.mkv”. The video shows a preview in the middle of the screen. I used the video controls directly under it to pause the video.
I clicked on the “plus” icon above the Timeline to add the video to it. I used the slider to change the way the videos are displayed on the timeline.
Now I go to file Open File again and select my second video and do the same thing. Now I have two videos on the timeline. I’m going to save this now just to test it out.
Click on the “Export” button in the top menu. A menu of presets opens on the left-hand side. I didn’t change anything but clicked on the “Export File” button. Name and save it.
The progress bar appears on the right-hand side in the “Jobs” section.
A white check mark in a small green box appears when the job is done.
The end result was a MP4 file. 38 minutes long and 909MB in size. It took about 15 minutes to complete. The video and sound quality was pretty good.
