Have you asked the BI developer about this issue?
You can have BI record directly to MP4 files if you want (keeping in mind that they won't be usable unless/until they are properly finished writing).
I would prefer to BI myself also. That being said, the free VLC will also record a RTSP stream and save as MP4, albeit maybe without as much configurability (is that a word?) as BI.
You can buy a second license for 30 dollars. Email support.The main reason to not use BI is that the computer i want to use to record is not my BI server so i would have to get another BI licence.
I have no idea i'm not a native english speakerYes VLC should do the trick. Just need to figure out the RTSP link adress then i guess.
When you export from Blue Iris, it is best not to re-encode the video at all. It is much faster that way and you keep full quality. When you re-encode you lose some quality and you may even end up with a larger file size depending on the encoding settings!
