Is there an AVI file joiner that will do "batch" joining?

Most of the online AVI file joiner allows you to join videos in batch online for free. However, I still recommend you try the desktop video editing tool to merge AVI files, instead of the online tools. It's risky to use online tools unless you don't care about your privacy. Below are the 3 mostly widely used AVI joiner for Mac (macOS 10.13 High Sierra) I suggest you try. Choose the one that's right for you.

Part 1: Join AVI videos in Filmora Video Editor

No matter you need to merge AVI videos on Mac or Windows PC, Filmora Video Editor for Mac (or Filmora Video Editor for Windows) allows you to merge AVI files on Mac (macOS 10.13 included) easily. AVI, as well as other video formats and photos are fully supported. While you join AVI videos with this AVI joiner, you can import some photos, joining them to the videos. Besides, there are multiple transitions and intro/credit available for you to put them to the AVI videos, making it look naturally for the scene shifts.
