As long as users above LV2 and users with annual fees have the privilege to upload local videos in QQ space. At present, there are three ways to upload videos in space: inserting them in the log, uploading them in the photo album video and uploading them in the video application. These three entrances to upload video files are consistent, and the qualification to upload videos every day is used together in these three places.
First, the entrance to upload video;
1. Log upload: enter the log writing state, find the icon ""for inserting video, and select "Upload from local";
2. Upload a video album: After logging in to your Q space, click Album = "Video =" and click "Upload Video" in the upper right corner;
3. Upload my video on my homepage and click "Upload Video".
Second, the number of local videos uploaded by QQ space every day.
I hope it helps you.
