Wechat video can't be transferred to SMS.

Bad network conditions, too big video, etc.

Poor network condition: If the current network condition is poor, the data transmission speed will be reduced, which will lead to network delay. This will prevent the video data from being transmitted to the receiving end in time, thus causing the situation that the video cannot be sent out. At this time, please check whether the network connection is normal or try to switch to another network environment and try again.

Video is too large: If the video file is too large and takes up a lot of bandwidth, it will take a long time to send or it will not be sent. You can try compressing the video file or dividing it into smaller parts, and then try again.
