This was a really quick JavaScript project that I made when I was a bit bored. I wrote it originally with Python, but I wanted to port it to JavaScript, so it is easy to use in browser or something.

It is render time estimator. Just type frames or frame range and average time how much it takes to render a single frame and then render time estimator calculates how long it takes to render whole sequence.

Time should be given in HH:mm:ss format.

Try it here: Render Time Estimator
