You’re welcome! Glad I could help
The first item was pretty straightforward to find. If you look closely at the bottom right of the video you’ll see tiny barely noticeable watermark, which is the logo of the author. I knew the author so all it took a visit to the author’s profile and a quick scan through their items to find the item.
For the second item I took screenshot from the video at 0:00 and did a reverse image search on Google. Very surprisingly the item you wanted was the first search result. That was totally unexpected. I was planning to find the video playing in the background of the preview video and then use that to narrow down my search on Videohive, but luckily I didn’t have to do any of that
