We are using Remotion Lambdas as well as rendering videos in our UI for user previews. I've been trying to document upgrade paths for our team and currently when we upgrade we bump all versions in our apps and also redeploy lambda functions as documented. However, I don't see any documentation around rebundling. My question is, when we upgrade and redeploy a Lambda, do we also need to create a new site to go with it? In which case we would probably deploy versioned sites ( e.g. npx remotion lambda sites create --site-name v4.0.245 ).

We haven't been doing this so far and haven't come across any issues, but it might just be good luck, so wanted to confirm best practice.

yes, you should update the site

Question about the new Video component and its fallback to OffthreadVideo behavior.

I see there's a fallbackOffthreadVideoPropsprop on the Video component.

The question is, what happens with "loop"? The new Video component supports the loop property, but OffthreadVideo does not. So what would happen if, during rendering, the component needs to fallback to OffthreadVideo and it was set to loop? It certainly won't loop, right? Anyway to resolve this inconsistency?

Hi All, I am using the remotion lambda. I use it together with python remotionclient. I would like to get the progress of the render currently going, but that's impossible.

Normally it is, but i changed invoke lambda a bit. I cannot wait until the lambda is finished, as the lambda is triggered within a request of my webapplication. For that i subclassed RemotionClient and created an invoke lambda function which triggers the lambda without having to wait for it

response: Dict[str, Any] = client.invoke( FunctionName=function_name, Payload=payload,

Async invocation

Hi! I'm struggling to get the lambda rendering to work. I followed the setup guide and everything seems to be deployed correctly, with 4096mb memory. I am using the latest 4.0.377 with a simple composition. With verbose logging I see:

INFO Ensured browser is available.
INFO    [openBrowser()] Opening browser: gl = angle, executable = /opt/bin/chromium, enableMultiProcessOnLinux = false
ERROR    Error occurred c$: Protocol error (Target.setDiscoverTargets): Target closed.

What can this be?

Hi, I want to know if my project already uses shadcn/ui and has its own theme configuration (mostly colors), after I purchase the editor starter, will I have to resolve complex theme or CSS variable conflicts?

jonnyburger - 10/23/2025, 8:21:44 AM

we did take some shadcn components, but there is no custom theme. we only have very few extra CSS variables defined

I think you will only have a conflict, if you have made changes to the tailwind theme externally

https://community.rive.app/c/support/

I see that Rive has built a community section, which they seem to be favouring over Discord. I assume this is an effort to help with discoverability of solutions, as search engines (and LLMS) would be able to index the questions and answers. Not sure the Remotion team would want to maintain the forum tech, but thought I'd post it here for consideration all the same

jonnyburger - 4/17/2025, 10:03:53 AM

we also have some efforts regarding this
