Download of JoinMovies 1.0.2 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Audio & Video Tools, more precisely Editors & Converters. This Mac application was originally created by Tomoyuki Okawa. According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software.
From the developer:
JoinMovies is an application that specializes in combining multiple video clips (not parts) of the same format (or similar ones) into an independent movie file. You can join QuickTime-readable movie files (3GP, 3GP2, DV, M4V, MOV, MP4) and make one independent video clip (MOV), which is viewable with a media player.
You may want to check out more Mac applications, such as MFilter, Aiseesoft WMV Converter for Mac or AkBrowser, which might be similar to JoinMovies.
