Sora
OpenAI's text- and image-to-video model with a storyboard editor and a social-style Sora app.
+ Sora 2 generates synchronized audio and dialogue with its video and the cameo feature inserts real people consistently.
− Heavy content restrictions, watermarks on free output and generations fail or queue at peak times.
Open Sora ↗ best for: short social clips with sound

+ The strongest fully open video model, with a 1.3B variant that runs on consumer GPUs and broad ComfyUI support.
− Local generation is slow (minutes per clip) and the larger 14B model needs a high-end GPU.
+ Gets day-one support for new open models (Flux, Wan, Hunyuan) and lets you wire up any pipeline you can imagine.
− The node graph has a steep learning curve and shared workflows frequently break on missing custom nodes.
+ One-click camera presets (crash zoom, bullet time, FPV) deliver dramatic shots without prompt wrangling.
− Presets dominate the product; free-form control is limited and credits are consumed fast.
+ Aleph lets you edit existing footage with text instructions, which few competitors offer.
− Credits burn fast and clips are limited to roughly 10 seconds per generation.
+ One subscription gives access to Flux, Veo, Kling, Wan and others plus a strong enhancer, so you rarely need another tool.
− It is an aggregator, so model availability and pricing shift often and credits drain quickly on video.
