How to join several AVI files

Step 1. Install the AVI merger

Step 3. Insert transitions

You can insert stylish transitions between the individual video clips so that they flow smoothly from one to the next. Open the Transitions tab to review the available transitions. Drag the desired transition to the working area and drop it between two video clips. If you want to quickly add transitions between all clips, click the Transition wizard button above the working area and choose the desired transition style and duration. For more details, read our guide about adding animated transitions to a video.

Step 4. Save your video

After you have finished editing, click the Export button and choose the size, quality, and format for your video. If you want to watch the video on a mobile device such as a smartphone or tablet, click the Save for devices tab and choose the appropriate device model.
