I merged the official fl2va workflows.(minimax-h3_fl2va-Mix)
you can process t2va,i2va(first_image),l2va(last_image),fl2va in one workflow now.
Reference output:
RTX5080 laptop 16G vRAM + 64G RAM T2V&I2V(pruned_int8_conv; 8s*1376*768): Prompt executed in 00:20:12
T2V use the official example prompt.
