you don't need Seedance 2.5, here's cheaper and more efficient workflow
we made this entire game shooting scene in one shot for $1.97 with DeepSeek V4 Flash 0731 + MiniMax H3
we use DeepSeek to code the raw Three.js scene first: exact camera movement, character motion, timing, everything. keep tweaking it there for basically pennies. then feed the final footage into H3 and let it cook the realism
48 mins, $1.97 total, one H3 generation
way cheaper than rerolling a video model 10 times
