Comparisons with baseline methods

We compare our method against existing methods using still images with a wide range of content (e.g., landscape, human, animal, vehicle, statue) and style (e.g., real-life, AI-generated, painting, clay, anime, isometric illustration).

Motion control using text

"Man talking"	PikaLabs	Gen-2	DynamiCrafter (Ours)	DynamiCrafter_DCP (Ours)

"Man waving hands"

"Man clapping"

"Girl dancing"	PikaLabs	Gen-2	DynamiCrafter (Ours)	DynamiCrafter_DCP (Ours)

"Girl waving hands"

"Girl twirling her hair"

Applications

Storytelling with shots. We can use ChatGPT (enpowered by DALL·E 3) to create several shots of a story and then generate storytelling videos by animating these shots. [Image source]


	"A disheartened bear sat by the lake, hanging its head."	"He is meeting a girl and introducing himself."
	"He chatted happily with that girl by the lake."	"Before leaving, the girl told him to be positive."

Looping video generation (@320×512 resolution).

Generative frame interpolation (@320×512 resolution).

Other controls

FPS control.

"An anime scene with windmills standing tall in a field and blue sky"	FPS = 30	FPS = 10	FPS = 5

"A boat moving on the sea"	FPS = 30	FPS = 10	FPS = 5

Multi-cond classifier free guidance. Higher s_txt and s_img indicates a more significant impact for the text prompt and image condition, respectively.

"A statue of two men with wings are dancing"	s_txt=s_img=7.5	s_txt=1.2, s_img=7.5	s_txt=7.5, s_img=1.2

Ablation study

Dual-stream image injection.

"A camel in a zoo enclosure"	Ours	w/o ctx	w/o VDG	w/o λ	Ours_G

Training paradigm. Visual comparisons of the context conditioning stream learned in one-stage and our two-stage adaption strategy.

"A man hiking in the mountains with a backpack"	One-stage	Our adaption

Training paradigm.

"A girl with short blue and pink hair speaking"	Ours	Fine-tuning entire.	1st frame condtion

Limitations

Challenging case in terms of image content understanding.

"Moving clouds in an anime scene"	Output

Inability to generate specific motions since the dataset lacks precise motion descriptions.

"Girl rubbing her eyes"	Output

Inheriting slight flickering artifacts and human face distortion issue from the pre-trained low-resolution T2V model.

"Old man walking with his wife"	Output
