The generated results are very shaky.

Thank you for your excellent work.

my result is in the url:  `wget http://xlabt.cn-zhangjiakou-d.oss.aliyun-inc.com/transfer/hjj/tmp/result_bixin.mp4`

The result was very shaky, and there were also issues with the head fluctuating in size.
Are there any parameters that can be adjusted or methods to solve this problem?

Thanks a lot.
