How to batch process Timelapses using Automator and Quicktime 7

Hello all!

I have around 70 time lapses I'm looking to batch process as quickly as possible and have been trawling the internet to try and find a way.

The best I have found is in this piece of AppleScript on the forum linked.

When I tried this, the movie came out wrong. My JPGs are at full res (5760x3840) but I want the quicktime to be 1920x1280. I'd also like it to be 25 fps.

How could I adapt that AppleScript to make my process work? I'd also like it to be named the folder name rather than the first of the sequence. I only have Automator and Quicktime 7 available (this is a hired machine).

Any help would be fantastic. I'm a n00b when it comes to scripting.

Thanks in advance.
