The single most important first criterion to verify is Support for the required modalities that is text to video.

Inference latency for generating video clips is important for user experience and scaling, yet it only matters after you confirm the model can perform the text to video task at all.

Availability of customization or fine-tuning features can help align outputs with brand style or domain needs, but it is secondary to verifying that the base model supports text to video generation in the first place.

Maximum input context window size for prompts is mainly a constraint for large language models doing text processing. The scenario uses short prompts to create video, so context window size is not the primary gating factor compared to verifying modality support.
