Google Veo 3.1 vs Kling 3.0 4K
Both generate native audio and both are available inside EzUGC. The difference is clip length, resolution and what a render costs.
The short version
Google Veo 3.1 renders one fixed 8 seconds and offers 720p and 4K. Kling 3.0 4K renders 3 to 15 seconds at 4K only. A vertical 8 second render costs 1000 credits on Google Veo 3.1 at 720p and 1000 credits on Kling 3.0 4K, so at that length the question is resolution and control rather than price.
Both models take image input and generate synced audio, so the same prompt structure works on either: a subject, a setting, a camera note and a quoted spoken line.

When to pick Google Veo 3.1
Pick Google Veo 3.1 when your script fits one 8 second beat. A hook, one proof moment and a short closing line is the natural shape, and the fixed length keeps pacing predictable.
It also suits teams that want first and last frame control, since both end frames can be pinned to product images. For cheaper drafts, Google Veo 3.1 Fast renders 8 seconds at 1080p for 320 credits.

When to pick Kling 3.0 4K
Pick Kling 3.0 4K when the clip needs a different length. Lengths from 3 to 15 seconds are available, so a 5 second bumper and a 14 second demo both come from one model.
It is also the choice when 4K output is the requirement. Cheaper Kling tiers, Kling Video 3.0 Standard at 320 credits and Pro at 480 credits for 8 seconds, let you test the script first.

Using both models
A practical split is to draft hooks on the cheaper tier of either model, then render the approved script on Google Veo 3.1 for a single 8 second ad or Kling 3.0 4K when the cut needs to run longer or finish at 4K.
At 8 seconds they match at 1000 credits, with Google Veo 3.1 at 720p and Kling 3.0 4K at 4K. Kling gets cheaper for shorter clips because it bills 125 credits per second, so 5 seconds costs 625.
