The Video Activity Coder is a free, open-source computer program that can assist in coding behaviors in videorecorded datasets. Several programs already exist with this purpose; however, some of these are quite expensive, whereas some open-source, free alternatives have limitations. The Video Activity Coder allows a user to view recorded observations with the ability to play, pause, rewind, and fast-forward video clips easily. Users can mark the beginnings and endings of behavioral codes by using an onscreen keypad. For example, one could note every instance of a child manipulating toys by pressing a key or note the beginning and end of when a parent assists a child. In addition, the program offers descriptive statistics and output that captures second-by-second streams of codes that can be analyzed with other programs.

Video Activity Coder 是一个免费的开源计算机程序，可以帮助对视频记录数据集中的行为进行编码。已经存在几个用于此目的的程序；然而，其中一些非常昂贵，而一些开源、免费的替代品有局限性。视频活动编码器允许用户查看记录的观察结果，并能够轻松播放、暂停、倒带和快进视频剪辑。用户可以使用屏幕键盘标记行为代码的开始和结束。例如，可以记录孩子通过按键操作玩具的每一个实例，或者记录父母帮助孩子的开始和结束。此外，该程序还提供描述性统计数据和输出，可捕获可与其他程序一起分析的逐秒代码流。
