使用技巧与最佳实践 / Tips & Best Practices
Choose Appropriate Quality
4K and 1080p quality files are large, suitable for large screen viewing. If only watching on phone, 720p or 480p is clear enough and files are smaller. Choose MP3 format for music only, significantly saving storage space. Choose appropriate quality based on device storage and usage.
Respect Copyright
Downloaded videos are for personal learning and appreciation only, not for commercial purposes or re-uploading. Respect original creators' work and do not infringe copyright. For commercial use, contact original author for authorization. Support favorite creators by watching original videos and liking/subscribing.
Check Storage Space
Ensure device has enough storage space before downloading. 4K videos may exceed 1GB, longer videos are even larger. Regularly clean up unnecessary downloaded files to free up space. Can use cloud storage or external storage devices to save large amounts of videos.
Network Environment
Recommend downloading videos on WiFi to avoid consuming large amounts of mobile data. High-quality video downloads require stable network connection. If download is interrupted, you can retry. Some networks may limit video download speed; be patient.
File Management
Downloaded videos are saved in device's default download folder. Recommend creating dedicated folders to categorize videos, such as "Education", "Music", "Entertainment", etc. Regularly organize files, delete watched or unnecessary videos to keep device tidy.
