The frequency range is set to be 1~1.8. How can we get these value? It's said that heart rate should located within 0.4 ～ 4 Hz.

I used ffmpeg to convert the video format from .mkv to .avi .mp4 .mov Three types of videos got different results. And it happened on another video too. So I modified the heartrate.py

add : print("peak is: ",peak,"hight is: ",fft_maximums[peak],"In this case HR is: ",freqs[peak]*60)

video.mp4
peak is: 12 hight is: 2.968162773664705 In this case HR is: 71.70124481327802
peak is: 14 hight is: 2.600039322516675 In this case HR is: 83.65145228215769

video.avi
peak is: 10 hight is: 3.3830124388984726 In this case HR is: 60.0
peak is: 14 hight is: 2.704215718114888 In this case HR is: 84.00000000000001
peak is: 16 hight is: 2.337397877666178 In this case HR is: 96.0

video.mov
peak is: 12 hight is: 2.968162773664705 In this case HR is: 71.70124481327802
peak is: 14 hight is: 2.600039322516675 In this case HR is: 83.65145228215769

same as video.mp4

It seemed mp4 mov format is a good choice.

but when I use mp4 file (record by my mobile phone) error occurred

Traceback (most recent call last):
File "C:\Users\94047\Desktop\eulerian-remote-heartrate-detection-master\main.py", line 39, in
print("Heart rate: ", heart_rate, "bpm")

I found that the output parameter "video_frames" of preprocessing.py sometimes will keep blank (no data) when the person wearing the glasses in the video.
Have you encountered a similar issue before?
