First of all, I have solved this problem. If the official account video of WeChat wants to be clearly displayed on the official account of WeChat, your original material must be high-definition, otherwise there will be no high-definition effect no matter how it is transmitted. It's our studio WeChat to rectify the lack of wine in Liu Wu. If your question is that the original material is also high-definition, and the webpage is also high-definition, but it is vague in the official WeChat account, then I suggest you help us fill it in, which will be more targeted rather than blindly doing it. Finally, I wish you good luck in your work!
