--png gives a folder with png sequence. How can I save as mp4?

I get this error. and the video does not save.

Traceback (most recent call last):
  File "/content/arXiv2020-RIFE/inference_video.py", line 294, in <module>
    os.rename(targetNoAudio, vid_out_name)
FileNotFoundError: [Errno 2] No such file or directory: 'video1_4X_99fps_noaudio.mp4' -> 'video1_4X_99fps.mp4'

I'm not too sure why your mp4 can't be exported. I personally recommend using mmfpeg to process png images to mp4.

ffmpeg -r 60 -f image2 -s 1920x1080 -i pic%04d.png -vcodec libx264 -crf 25  -pix_fmt yuv420p test.mp4

I found the above but I don't know how can I tell to pick the outputted folder in this command

Also, originally, I wanted to ask how can I set the output format to mp4?
I know its --png for PNG sequence but I don't know what is it for MP4? is it --mp4??
Sorry I am learning

the size of every interpolated png is 1.5 MB(1080p). which makes a 2 minutes video like 20GB or so. I don't want to export into PNG. This is the same when I use RIFE in flowframes. video formats result in smaller size for flowframes. thats why I wanted to know how to export into video formats.

and thanks for your reply
