Suggestions on AVS3 encoding video

I have several large-capacity videos encoded by AVS3, all of which are 8k high-definition videos of the China’s Central Spring Festival Gala and the Olympic Games. They are all about 200gb single. The picture quality is extremely clear, but there is no picture when playing with infuse, only sound. I hope the official can help and support me, because the file is too large, and I can only use the 115 network disk for transmission and sharing. I also know that the 115 network disk is also used in foreign Apple stores. I hope the official can receive my test video and repair and support it. If possible, I will release the sharing
