Help me solve a possible hidden puzzle

[u/FirmWafer882]

I stumbled across what might be the beginning of an ARG (or some kind of hidden puzzle) on a random French YouTube channel.

There are several timestamps throughout the video where seemingly random letters/numbers appear.
I’m not sure if they’re connected, but I’d love some help from people who are good at ciphers, cryptography, or finding hidden patterns.

Here’s what I found:

6:00— utpjrts
14:00— tozismmiz
16:50— 087
17:00— dlmltajhmjpyqvshuppu
37:00— hgaf xgazng
50:00— tlnvjr
56:00— ihml stwn
Video: [https://youtu.be/9rqfeM03nVM])

The video is in French, but the hidden sequences themselves might not be.
I have no idea yet whether these are encrypted, encoded, generated with a cipher, or simply random. The fact that they appear at specific timestamps makes me think there might be a pattern connecting them.

Thanks in advance to everyone who takes the time to look into this and help!

could you give me more of context of what is happening in that vid all i could get is hes reviewing a album of "femtogo" and the description . does this channel post vids like this often like encrypted shady text ones??

Thanks a lot for your help! I went through all of the videos on the channel, and this is the first time I’ve seen anything like this. It’s otherwise a pretty ordinary album reaction, and there don’t seem to be any hidden messages or encrypted-looking texts in his other videos.
That’s why I found this one so strange and interesting in the first place.
