Inspired by our brother subreddit: audioengineering This subreddit is open to anyone to discuss, share and show their work, as well as ask questions towards anything concerning video production. From a dad with a camcorder to a professional engineer at the superbowl, or a small meeting room operator to a widescreen specialist, projectionist, LED wall engineer or a electrical video engineer. All things video are welcome! Feel free to post anything you like from questions to pictures. Remember that no question is stupid and we work together to create a friendly community.
If you have any questions or suggestions please feel free to messsage the moderators! We would love to make this a great and successful subreddit for all of us video engineers!. Quick link to:.

For those familiar, OBS has an extremely useful source called 'Browser Source' which captures a URL's web-based content. Essentially anything that appears in that window will appear on screen, and if there is nothing, the background is completely transparent so it doesnt show anything at all. This is the method by which most Twitch streamers show automatically personalized live follow, donation, and subscriber alerts. The web-page that is being captured automatically pulls data from twitch and creates a nice animation displaying the info. This type of source is extremely useful and can have many applications in even professional settings, such as grabbing live stats from an API and displaying them on screen automatically without needing to input anything manually at all. I am wondering if any tricaster (in particular the TC1) is capable of having this kind of browser source.
I know you can capture a browser window as an NDI source using NDI Tools, but that captures the entire window, not just the web-content within it. If anyone knows the answer to this or any insights, it would be greatly appreciated! CasparCG is a graphics/video server. It works as a client/server relationship.
The server is what does the heavy lifting. It can run on Windows or Linux.
Since you have a Tricaster you'll use NDI output, but if you had a different switcher you could also get a Blackmagic card for key+fill output. You'll need to download the CasparCG server, the proper NDI driver, as well as the CasparCG client. (The client does not have to run on the server, but it can.) CasparCG has channels/layers system, just like some other CGs on the market.

A channel is an output, in your case, NDI. You can pile as many layers on a channel as your hardware will support.
In the config, you will want to setup a sever channel with the resolution you want, and a NDI output. (You could even setup a second channel to play videos/images/graphics.) Then you use the client to load the URL on a layer. Assuming your web page is setup for transparency, CasparCG will output the key+fill over NDI. You just need to connect the NDI on the Tricaster and then set the key source to the NDI input. The transparency will magically be there. Unfortunately CasparCG is not the most user friendly product out there. The tradeoff though is that it's free.

Check the CasparCG forums for help, especially in locating the correct NDI driver. (The last time I did this NDI was still called IVGA, so unfortunately I can't be much help with the specifics.).
That is possible but not really what I would like to do, as it will not have the transparent background of the web-content which provides a perfect cutout of anything appearing or moving in the page. Capturing the browser window will show the background color of that browser. And while it is possible to choose the background color and key it out, the keying can be very fussy and will have problems with any colors similar the background color and with certain effects like smoke or fades.
