[Feature request] Allowing users to choose the storage path for the temporary files

[ffainy]

Hello, this tool is fantastic and very useful to me. Thank you for your hard work💕

However, I encountered a problem while using it, and I hope you can consider optimizing it.

For example, I want to merge an entire folder of WebP images into a single video file. The folder contains hundreds of WebP images, each over 10MB. I suspect this tool first converts each WebP image into a separate video file before merging them. These separate video files are temporarily stored in a temporary folder on the C drive, which consumes a lot of space on my C drive. My C drive is a 256GB SSD, and then my C drive explodes🤣

Allowing users to choose the storage path for the temporary files would perfectly solve this problem👍

Hello,
the pipeline for combining option is: decode all WebPs → flat PNG sequence → single ffmpeg concat-demuxer pass.
There's no "convert to mp4 then concat the mp4s" step.
So in non technical explanation it would
Extract all attached webp images frames and then merge them into a single video file. So you're encoding only 1 time.

The tool should clean-up tmp after finishing the job.
But ill look into what u said its actually a good UX option.
Since you mentioned hundreds of webp files you actually gave me an idea of sorting videos order before combining...
