Change temporal route path?

[SergioGracia]

Hello everyone!

I would like to know if there is any way to change the default directory where Remotion stores temporary images when rendering a video. Right now everything is dumped to "/tmp" and my idea is to be able to do it to "/data/tmp". I've looked at the documentation but haven't seen anything about it.

Is it possible to change it?

Hi @SergioGracia! Indeed, that is currently hardcoded and cannot be changed.

We can consider this feature - what is your motivation to use a different directory?
Understanding the reason behind this request would surely help us better think through the implementation.

Thanks for the reply! To give you some context, I have a unit mounted in /data/tmp with 50 gigabytes free and I would like to use it instead of /tmp since it can become saturated if I launch several video generation processes in parallel.

In fact in some stress tests I've done it reached the point of "cannot write to disk: no space available" relatively quickly.

I have a ~60 gigabyte SSD that has three partitions, something like this:

• / (root): 45% of total
• /home: 45% of total
• swap: 10% of total

And a 1 Terabyte hard disc mainly to store almost all of my data there.

If I want to make a 20 Gigabytes of video using Remotion I can't have the project on my SSD.
I think for a video of size 20 Gigabyte we would have almost 20 Gigabytes of temporary cache so I should not exceed more than available_space/2 of my partion space.

If I could have a flag on the CLI or I would be able to set my setting in a .env file to use something like /path-to-hd/remotion_tmp as my tmp directory it would help.

I have a directory in my SSD, mainly I do work on my projects that are in that directory, if I can manage to have Remotion projects in that directory it would be a plus for me too.

@SergioGracia @kave-me I found a solution!

Node.JS will respect the TMPDIR environment variable on macOS and Linux, and the TEMP environment variable on Windows.

So set the TMPDIR or TEMP environment variable either globally (put it in your .bashrc for example),
or just for the Remotion script (TMPDIR=/custom/tmp npx remotion ...)

Thankyou!!!! I'll try this as soon as possible. :)
