Hi there, sringsmuth...
Thanks for the additional information and screen shot. This helps a lot! I can see where your setup would be helpful for your students. You're probably already aware, but if you were to embed the Studio videos in your course, the length of each video is displayed as part of the embedded Studio interface, so you wouldn't have to manually type in the video's length on your own as it appears you are doing now.
There is also a "Description" text field in the "Details" tab of any Studio video...which you've also probably seen. But, this "Description" text box doesn't appear for students. Further, it doesn't handle paragraphs of text well at all...a real frustration of mine...to be honest. So, that's not going to be helpful for your needs.
I know this isn't what you were really asking about...but have you considered creating separate pages for each of your videos so they aren't listed on one page? While it's certainly nice to have everything listed and linked on one page, mobile devices should also be considered when designing course content. So, the longer your page is on the web, it's going to be more scrolling yet for your students who are using mobile devices with small screens. The idea would be to embed one video per page with a short page title and then the description of the video along with it embedded on the page. Again, maybe not ideal for your needs...but just throwing this idea out there for you to consider.
Hoping that this may help. Maybe there are ideas from others here in the Community that have worked, too.
