Hi @hystericblue32,
Welcome to the community 
To set the Default Binary Data Mode variable to filesystem in n8n Cloud, there’s no direct option to change this setting as you would in a self-hosted instance. One option is to upgrade to a higher plan which would give you more memory which might solve your issue.
You can also split your workflow into multiple sub-workflows with a parent workflow that fetches the recordings and another child workflow that handles downloading the files and uploading them to cloud storage. You can use the Loop Over Items node in the parent workflow to process small batches of a few urls at a time which should free up resources after each child execution so your n8n instance only needs to manage a few recordings in memory at a time. Here’s a similar post that might help!
If you’re stuck, you can also share your workflow in your post instead of a screenshot:
Tip for sharing your workflow in the forum
Pasting your n8n workflow
Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.
```
<your workflow>
```
Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!
