Both on starter and up. One plan, one pool of credits.

The short answer

Pick Kling 4.0 for anything longer than 8 seconds, up to 30, for square or 21:9 frames, and whenever price matters: 8 seconds at 1080p with sound costs 314 credits on Kling 4.0 and 534 on Veo 3.1. Pick Veo 3.1 when realism and spoken dialogue are the brief and the shot fits in 8 seconds, when the deliverable is 4K, or when you want a silent clip, which Kling 4.0 cannot render. Both take start and end frames, and on APImage both run on the Starter plan from one pool of credits.
