Blink integration video record, download and send

Hi,
I try to start a Blink camera with an automation when the doorbell rings and then download the video/image. I have written 2 automations for this.
The transfer and sending of the photo works without any problems. The video is sometimes saved ( /config/www/bell_last_video.mp4 as well as /media/media/camera/house_bell_{{now().strftime(‘%Y-%m-%d_%H-%M-%S’)}}.mp4 ) sometimes not. Sometimes it is saved but the previous video is sent. Does anyone have any ideas on how I can improve the behavior? I tried to extend the waiting time (until 2:30) but it didn’t make any difference.
