1. academic rigor: in the academic field, written records are rigorous and accurate, which can accurately express research methods and results. In contrast, video may be misleading or misunderstood due to shooting angle, light and other factors.
2. Readability and reproducibility: words are easy to read, understand and copy, especially on the network platform, and easy to share and spread. Video needs more time and energy to watch and understand, and can't be copied or quoted easily.
3. Cross-platform and cross-cultural communication: Writing is a universal and cross-platform language, which is not limited by hardware or software and can be used in different cultural backgrounds and language environments. However, video needs special playback equipment and software support, and it may be difficult for people with different cultural backgrounds and language environments to understand its content.
4. Intellectual property protection: Written papers can protect intellectual property through copyright protection and citation mechanism, while videos are more likely to be stolen or infringed.
5. Restrictions on academic journals: Most academic journals require papers to be submitted in text form, so video papers may not be accepted or recognized.
In short, although video has advantages in some fields, in the academic field, writing is still the main tool for communication and knowledge dissemination.
