how to make a mp4 video file with many jpg photos?

I want to find any way for making mp4 file with many jpg photos (just like gif form).
I tried to find someways (such as react-native-ffmpeg …)
but until now, I cannot find anything which is suitable for expo.

If anyone have some idea or experience, please share with me.
Thank you.
Best Regards.

You might need to write a config plugin, though.

Thanks in advance.
