Summary

When I click the Reset to Defaults button in the Video Parameters node, it should populate the default values for the video system.
The defaults vary depending on which color system and video line system is in use.

Non-exhaustive list of color / video system combinations that will need a unique set of "defaults":

• PAL / 625
• NTSC / 525
• PAL / 525
• (perhaps others)

Steps to reproduce

1. Load a vhs-decode Y/C TBC decode
2. Add the video parameters transform node, as seen in the screenshot
3. Right click on the node, click Edit Parameters
4. Click Reset to Defaults, and nothing is changed from -1

Expected behavior

Clicking the Reset to Defaults button should populate the video parameter options to the correct color / video system defaults.

Actual behavior

It does nothing.
