Creating a video through MCP and getting file not found
One video generation worked but all the ones after, using the same MCP and the same agent (OpenClaw) doesn't work:
Heygen video rendering error
I am trying to create a heygen video for my AI agent. Basically the heygen video should act as a front face of the AI agent where it should be able to talk whatever text the agent gives. I am using free version of the API key and as per documentation, the free version should be able to render the video upto 720p resolution without any errors.

Hi HeyGen team,
Technical Inquiry: Face Selection & Speaker Isolation in Multi-Person Photos (v2 & Avatar 4.0)
Hello Engineering Team,
Avatar IV endpoint /v2/video/av4/generate always outputs video with background — no transparency support?
The generated video always contains a baked-in background.
We need to place the avatar video on top of another background video, but the output does not include any alpha channel or true transparency.
Finding and Installing Video Agent API + Claude Code Skill.
I watched this HeyGen video on LinkedIn but simply couldn't follow it; one of the critical steps was rushed or perhaps the speaker just assumed that viewers would know what to do. Anyway, this looks like a great skill if I can work it out. They key step that was missed/rushed in the video was to show where to actually locate and then copy/paste the skill. Is this located somewhere on HeyGen or do i have to go to some other site to access it? Sorry, I normally can follow these things - I know how to create a HeyGen API and how to install a Claude skill but this one had me stumped. So hope someone can help?? Thanks!

Hello HeyGen Support Team,
voiceChatTransport cuts Interactive Avatar off and injects messages we didn't specify
We’ve been trying to track down the cause of increased latency for our non-US users. We went as far as setting up a new environment in another region for our application but found that the bottleneck seemed to be the avatar. While troubleshooting internally, we toggled the voiceChatTransport to “livekit” via the SDK’s createStartAvatar function and that seemed to immediately help significantly with latency, but the very first message we tell the avatar to repeat after the connection is established gets cut off and it starts speaking a different message we didn’t send. Is there a way we can have voiceChatTransport set to "livekit" without that undesirable message cutting off the text we asked the avatar to repeat?
