I use spout2 plugin for obs (https://github.com/Off-World-Live/obs-spout2-plugin) and create a new ‘spout2 capture’ source in obs to capture from veadotube once the plugin is installed (also turn on spout stream in veadotube program settings and transparency background which now works for me in v2.1). That should allow semi transparent parts to work as well (which chroma filter was not properly capturing for me)
