wild video infer too slow

[Ared521]

Hello, may I ask, I deduce that my own video speed is very slow, 10s video takes more than ten minutes, and there are some warning messages, may I ask why?

MAGEIO FFMPEG_WRITER WARNING: input image is not divisible by macro_block_size=16, resizing from (923, 924) to (928, 928) to ensure video compatibility with most codecs and players. To prevent resizing, make your input image divisib

le by the macro_block_size or set the macro_block_size to 1 (risking incompatibility).

I recall running into this issue as well. In my case, my gpu memory was being occupied but my gpu utilization was still 0%. Could you check your nvidia-smi output? I never explored further to debug my issue, but hopefully this gives you some insight to check your installation / setup or the gpu utilization in the scripts.

Thanks for your reply. I found the infer speed was very fast, and the main time was spent on render
