Tested character consistency across 5 models with the same prompt

Reddit r/AI_Agents News

Summary

User tested character consistency across five AI video generation models (Kling 3.0, Runway Gen-4.5, Veo 3.1, Seedance 2.0, Pika) using same prompt and reference image, finding Seedance 2.0 best (8/10) and Pika worst (3/10).

Got tired of arguing about which model holds characters best so I just tested it myself. Same prompt, same reference image, generated 10 clips on each and counted how many kept the face recognizable. Kling 3.0: 5/10. Fine for single shots but across cuts the face drifts noticeably. Jaw structure changes, eyes shift. Runway Gen-4.5: 6/10. Better than Kling but hair and skin tone wandered in a few clips. Veo 3.1: 4/10. Great cinematic quality but character consistency is clearly not their priority right now. Seedance 2.0 (capcut video studio): 8/10. Same face held across wide, medium and close up. Two clips had minor drift around the hairline but nothing that would break a sequence. Pika: 3/10. Love Pika for effects and weird stuff but don't use it if you need the same person twice. Not a scientific test obviously but if your workflow depends on keeping a "cast" this is the pecking order right now. Happy to share the clips if people want to see.
