Solved Laptop specs for making youtube videos

I know this is a help forum, but I don't really have a problem and will understand if you don't treat these kind of questions. It's more some suggestions that I need in order to buy a laptop good enough for making videos. My current pc is a little too slow and when exporting a video it takes 3x longer than the video itself. Therefore I'd like to know what would be the optimal specs for an entry level pc? I was suggested one, below is the info, I'd like to know if it may be sufficient, although for this one the monitor is smaller than what I need. Which one of the specs could be improved from the ones indicated below? Would a refurbished laptop be ok vs. a new one?

Lenovo T470
Processor I7-7500U
16 GB memory
512 GB SSD

Thank you in advance.

Thank you for your response, I will take notice of your suggestions, nevertheless, I have to stay mobile, so a laptop is essential for me.

Well, the videos I want to make are 10 hour relaxation videos, where I take a short video and then loop it to create this long video. Here's an example . I could make them on my current laptop, but the two problems I have is that I cannot watch correctly the video in my video editor because it is too slow and also it takes 3x the length of the video to export it to mp4 format. I was suggested that it may actually be normal. Nevertheless, I would like to diminish the export time as much as possible, play video correctly while editing and as to video specs, I'd like to have a resolution of at least 1080p, but I think that is already an option in my video editor, although I'm not sure about a higher resolution. Actually, I'm just starting to explore the video making and if you have suggestions for something I didn't mention here concerning this kind of videos, please let me know. Anyway, I really appreciate your help .

Yes, those are the specs I was suggested and I think I found a suitable pc. Thank you very much for your help !
