Add colorspace option and change bit_depth to a combo on CreateVideo. - #15810
Conversation
📝 WalkthroughWalkthroughVideo APIs now treat color space and encoded bit depth as independent settings. Merge Risk: 🔵 Low · up to CreateVideo now exposes selectable color space and bit depth settings, but unsupported numeric bit-depth values may be accepted and silently encoded as a different depth. The PR is otherwise mergeable, with explicit owner follow-up needed to validate bit-depth values at the node boundary. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

Add color_space schema option coverage.
CreateVideo adds the color_space combo, but this test only checks bit_depth. Assert the color-space options and default so schema regressions cannot remove or alter supported HDR values.
Proposed test update
def test_create_video_node_bit_depth_options():
bit_depth_input = next(input for input in CreateVideo.define_schema().inputs if input.id == "bit_depth")
assert bit_depth_input.options == ["auto", 8, 10]
assert bit_depth_input.default == "auto"
+ color_space_input = next(input for input in CreateVideo.define_schema().inputs if input.id == "color_space")
+ assert color_space_input.options == ["sRGB", "HDR", "HDR PQ"]
+ assert color_space_input.default == "sRGB"As per coding guidelines, tests must cover combo options and supported colorspaces. As per path instructions, AGENTS.md requires tests to cover defaults and combo options.
