TVG is a training-free transition video generation method. It can enhance the video generation performance of models under the condition of generating videos given the initial and final frames.

Transition videos play a crucial role in media production, enhancing the flow and coherence of visual narratives. Traditional methods like morphing often lack artistic appeal and require specialized skills, limiting their effectiveness. Recent advances in diffusion model-based video generation offer new possibilities for creating transitions but face challenges such as poor inter-frame relationship modeling and abrupt content changes. We propose a novel training-free Transition Video Generation (TVG) approach using video-level diffusion models that addresses these limitations without additional training. Our method leverages Gaussian Process Regression (GPR) to model latent representations, ensuring smooth and dynamic transitions between frames. Additionally, we introduce interpolation-based conditional controls and a Frequency-aware Bidirectional Fusion (FBiF) architecture to enhance temporal control and transition reliability. Evaluations of benchmark datasets and custom image pairs demonstrate the effectiveness of our approach in generating high-quality smooth transition videos.

Please follow the instructions on DynamiCrafter to download the DynamiCrafter512_interp model and place it in the checkpoints/dynamicrafter_512_interp_v1/model.ckpt path.

We used the MorphBench and the TC-Bench-I2V. Please download the MorphBench dataset and place it in EvalData/MorphBench/Animation and EvalData/MorphBench/Metamorphosis. For the TC-Bench-I2V dataset, please follow the official tutorial and save the final frames to the EvalData/TC-Bench/youtube_videos_frames directory. You can refer to the corresponding files in the Prompts for specific paths. The images we collected ourselves are already in the EvalData directory.

To reproduce the experiments from the paper, please run

bash paper_exp.sh

in the command line.
