Capture with Window Capture or Screen Capture

When capturing the overlay window directly, you must set the capture method to Windows 10 in your streaming application. BitBlt or Game Capture will NOT work.

Start Hearthstone Deck Tracker.
Click the Options link in the top right.
For the purpose of setup, enable Show gameplay Overlay while Hearthstone is in the background in Overlay > General.
Launch Hearthstone.
Start a match against the Innkeeper (Modes > Solo Adventures > Practice in Hearthstone). You can use this game to setup and test your streaming scene(s).

Window Capture Instructions for OBS

Start OBS.
Add a new Window Capture source (e.g. called "HDT Overlay").
Select [HearthstoneDeckTracker.exe] HearthstoneOverlay. Set the Capture Method to Windows 10 (1903 an up) and Set Window Match Priority to Window title must match.
Adjust the overlay size within the composition view, make sure the overlay is on top of Hearthstone, and start streaming!

If the overlay is black, double check your HDT Capture Method - it MUST be set to Windows 10 (not BitBlt).

Capturable Overlay with Chroma Key (old method)

We used to recommend this method, and it still works. However, it can lead to magenta-colored artifacts in your capture, and so we recommend window or screen capture nowadays (see above).

Start Hearthstone Deck Tracker.
Click the Options link in the top right.
Open Streaming > Capturable Overlay.
Enable Show capturable overlay window. The default value for the Background color is #FF00FF (magenta).
For the purpose of setup, enable Show gameplay Overlay while Hearthstone is in the background in Overlay > General.
Launch Hearthstone.
For the purpose of setting up HDT, make sure Hearthstone is in windowed mode (not full-screen).
Start a match against the Innkeeper (Modes > Solo Adventures > Practice in Hearthstone). You can use this game to setup and test your streaming scene(s).

Chroma Key Instructions for OBS

Start OBS.
Add a new Window Capture source (e.g. called "HDT Overlay").
Select [HearthstoneDeckTracker.exe] HDT - Capturable Overlay. Set Window Match Priority to Window title must match. Enable Capture Cursor.
Right click the HDT Overlay source you just added and select Filters.
Add a new Chroma Key filter.
Set the Key Color Type to Magenta (default background color set above), Similarity to 350, Smoothness to 80 and Key Color Spill Reduction to 1. You may have to adjust these values a bit.
Disable Capture Cursor within the settings of your Hearthstone source. Not doing so will cause the cursor to show up beneath the overlay.
Close the Filter window, adjust the overlay size within the composition view and start streaming!

Chroma Key Instructions for XSplit Broadcaster

Start XSplit Broadcaster
Add a new Screen Capture source. Select any window.
Right click the source you just added, set Window Source to HDT - Capturable Overlay.
Enable Stick to title and Show Mouse.
Under Color > Keying select Chroma Key.
Enable Legacy Mode and with the Eyedrop Tool select the magenta of the overlay. The value for the first slider should become around -142.You can bring up the magenta overlay color by alt-tabbing until the window HDT - Capturable Overlay becomes active.
Adjust the second slider until you get the best result.
Adjust the overlay size within the composition view and start streaming!

The Hearthstone window contents pass through the overlay source automatically. It should not be necessary to setup a separate source for Hearthstone underneath the overlay.

Notes

Keep in mind that we are not streamers and we've put together these instructions to the best of our knowledge. It is possible that better or easier ways exist. If you know of either (or want to add instructions for other software not covered above), don't hesitate to reach out to us at support@hsreplay.net.
It's possible the Hearthstone game window contains a solid magenta color, caused by the overlay. Clicking within the game window once should remove it.
