Wolfram Video Processing is too slow in real-life situations. I love using Wolfram Language for real-life applications, and I appreciate that Wolfram has recently focused on first-class video functionality. However, it’s a pity that while it works fine for demonstrations, it is far too slow for practical use.

For example, when I use CapCut to edit and render a 5-minute video, it takes only a few seconds. But in Wolfram Mathematica, the same process is extremely slow. For a simple 7-minute video (with only text overlay), Wolfram takes 6 minutes just to render. That is unusable! Imagine processing a 30-minute video—it could take 45 minutes, while CapCut would finish in under a minute.

I have also tried adjusting encoders, frame rates, and other settings, but it didn’t help. Can someone suggest a solution? Thank you very much.
