你好，我看到你的代码里有RGB转YIQ的模块，但是实际上并没有使用这一模块，另外处理后的视频长度缩减一半，这是什么原因

the line is
filter_tensor=butter_bandpass_filter(lap_video_list[i],low,high,f)

Hi! I used magnify_motion("me.mp4", 0.4, 3)

and got

Hi
I had a few questions, i couldn't find your email on your github profile.Can we please speak?

Thanks

Good morning,
I'm a student at L'école des pupilles de l'air.
I would like to know if it is posible to have any contact with you. I'm working on the subject ''Eulerian magnification of video'' and I would be enjoyed to discuss with you about your project to better understand it and to better code it again in my way

Thanks for your time

If i run this code with baby.mp4, my system got hanged
if i run with the low quality it is working,but i am not getting the correct output.
pls help me to solve the issue
out.zip
this is my output

When I run the code on a custom video of the size 440x220, I get the following error using color magnification.

When I run the same video on motion magnification, I also get an error.

It seems as though the code only works with videos of certain sizes? Is there a way for me to make the code size-independent so I can run my custom video through it? Thanks.
