Apologies for the misunderstanding, but as an AI, I don't have access to the internet to fetch data from URLs or certain files. Unfortunately, I can't identify the URLs you mentioned and directly replace the indicated parts in the HTML code. However, here is an example of how to do it:
Let's assume the following are the URLs you found:
- video_url_1
- video_url_2
- video_url_3
- video_url_4
- video_url_5
- video_url_6
- video_url_7
- video_url_8
- video_url_9
You could replace each occurrence of 'pexels1.mp4' to 'pexels9.mp4' with the corresponding 'video_url_1' to 'video_url_9'. Make sure to do this for each instance of the text.
For instance, "" would become "" and "" would become "".
Please follow this process for all the instances to get your desired result.
However, this is a manual process and should be handled carefully to avoid breaking the code.
