SharePoint Migration API - MP4 Files get's an additional version after X amount of time.

[Tristan999]

Hi all,

I have a custom application that which uses the SharePoint migration API. There is a strange behavior where if I migrate MP4 for files it would migrate properly, but after an X amount of time, the MP4 file gets an additional version.

For example:

• I have a Test.MP4 file, it gets uploaded to SharePoint using the migration API. 
• The file in SharePoint is now tagged with the version label 1.0
• After some time, the file gets another version, 1.1, which shows the Modified By value SharePoint App

Hi,

I'd be interested to know why only .MP4 files get the "Modified by" Sharepoint apps. One of my user noticed the audio timing was slightly off compared to the video frames. After some investigation, we figured the root cause is the technician who converted the video. But still, the question remains: is there any sort of post-upload process that processes the MP4 files?
Anyone has an insight on this? And whether or not we can shut if off for a specific SPO site/library?
Thanks!
