uncovering details of images and videos

[Asecret]

I am a very new very inexperienced person navigating this world. I had inclinations (and actual events to lead to my curiosity) on uncovering details of images and videos sent to me by my "fiancé". In almost every single image sent it has been manipulated in some way. In one video he didn't even bother to hide the other person! (She had a hat covering her face from the wind on a boat, but I slow-mo and got a screenshot). Before I make any accusations or confront about anything I would like to make sure I am correctly analyzing these images. I understand this is drama for most- me as well- but I want facts.Also this has become extremely fascinating for me! I had no idea all the crazy and fun things you can do in photo editing! If anyone here has free time to help me in uncovering this mess please I would so greatly appreciate! (Also if anyone has experience with I think embedded data?) I am almost positive some links, songs, or images had hidden things either to monitor my phone or taunt me and make fun or maybe I'm just paranoid? But I'm on a new phone because the last one was ruined from that. Thank you in advance!!

Exiftool only edits metadata and doesn't edit video or image data. You can look at all the data in a file using the command in FAQ #3, but that doesn't guarantee that you can figure out if a file has been manipulated or not.

If you run the command in FAQ #3 on a file and there isn't very much information beyond the file system data, for example, there isn't a Make or Model tag, then it's likely to have been edited, as a lot of simple editors will strip away such data.

Also, any file that has been sent through text or social media will not have any metadata, as these will strip away all metadata for privacy.
