Why is my .mp4 file not saved after converting?

Question

I wrote a python3 script to communicate with my Raspberry Pi by sending telegram messages. Because my Pi is only able to take h.264 videos that i can't open on my mobile phone I would like to convert them into.mp4 files. Here's the code I'm referring to:

if command == ‘/video‘:
    name = datetime.datetime.now()
    dateiname = ‘/home/pi/Videos/Wettervideos/%s.h264‘ % name
    dateinameneu = ‘/home/pi/Videos/Wettervideos/%s-konvertiert.mp4‘ % name
    camera.start_recording(dateiname)
    sleep(10)
    camera.stop_recording()
    telegram_bot.sendMessage(chat_id, str(Video wird konvertiert))
    command2 = “MP4Box -add “ + dateiname + “ -new “ + dateinameneu
    call ([command2], shell=True)
    telegram_bot.sendMessage(chat_id, str(Video ist fertig konvertiert))
    telegram_bot.sendVideo(chat_id, video=open(dateinameneu,“rb“))

The message „Video ist fertig konvertiert“ is sent, but the.mp4 is not created. Neither in the right nor another folder it can be found. Thanks!

I just solved the problem. The.mp4 file couldn't be created because of the colons in the file name. (Datetime.datetime.now() separates hours, minutes and seconds with colons). Thanks for your comments.
