Video messages are easier to receive than text messages because of the lack of language and text barriers. In the past, when on-the-job training for junior employees were conducted in the manufacturing industry, they often carried out technical training with "mentorship system" or "work manual". This study aims at how video makes effects to those who work in manufacturing industries, especially those from other countries. Migrant workers from abroad or companies with manufacturing plants overseas have gradually used video manual as teaching materials for enterprise education and training, especially when COVID-19 becomes a global epidemic crisis. This study used in-depth interview research methods to investigate both workers and managers in the same manufacturing industry. The results found that when using digital cameras to record and edit, the production line equipment can achieve the following effects: (1) Promoting junior workers' self-efficacy; (2) Use of different language translations can provide simultaneous education and training for workers from multiple countries; (3) Putting digital teaching materials on cloud will make employees to use digital mobile vehicles to download and learn, that can save more time for employees.
