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?

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

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

we also have some efforts regarding this

wow thats a pretty cool demo

i wonder if it can animate smooth zoom in effect based on cursor position, we would bascially have a screen studio clone at that point and much better because it actually gives the files output with camera, allowing for further editing

	❯ use remotion best practices. this is our youtube channel: https://www.youtube.com/@remotion_dev. use curl scrape youtube to find the avatar and the subscriber count. multiple subscriber
	counts appear on the page, find the right one. make a white lower third that slides in from the bottom center. show the name, subscriber count and avatar. display a typical fixed width
	black youtube subscribe button that changes from "Subscribe" to "Subscribed". use a ease-out animation and for pressing in the button and a spring animation with a slight bounce once the
