In this work, we present Vlogger, a generic AI system for generating a minute-level video blog (i.e., vlog) of user descriptions. Different from short videos with a few seconds, vlog often contains a complex storyline with diversified scenes, which is challenging for most existing video generation approaches. To break through this bottleneck, our Vlogger smartly leverages Large Language Model (LLM) as Director and decomposes a long video generation task of vlog into four key stages, where we invoke various foundation models to play the critical roles of vlog professionals, including (1) Script, (2) Actor, (3) ShowMaker, and (4) Voicer. With such a design of mimicking human beings, our Vlogger can generate vlogs through explainable cooperation of top-down planning and bottom-up shooting. Moreover, we introduce a novel video diffusion model, ShowMaker, which serves as a videographer in our Vlogger for generating the video snippet of each shooting scene. By incorporating Script and Actor attentively as textual and visual prompts, it can effectively enhance spatial-temporal coherence in the snippet. Besides, we design a concise mixed training paradigm for ShowMaker, boosting its capacity for both T2V generation and prediction. Finally, the extensive experiments show that our method achieves state-of-the-art performance on zero-shot T2V generation and prediction tasks. More importantly, Vlogger can generate over 5-minute vlogs from open-world descriptions, without loss of video coherence on script and actor.

conda create -n vlogger python==3.10.11
conda activate vlogger
pip install -r requirements.txtOur model is based on Stable diffusion v1.4, you may download Stable Diffusion v1-4 and OpenCLIP-ViT-H-14 to the director of pretrained
.
Download our model(ShowMaker) checkpoint (from google drive or hugging face) and save to the directory of pretrained
Now under ./pretrained, you should be able to see the following:

Run the following command to get script, actors and protagonist:
python sample_scripts/vlog_write_script.py-
The generated scripts will be saved in
results/vlog/$your_story_dir/script. -
The generated reference images will be saved in
results/vlog/$your_story_dir/img. -
⚠️ Enter your openai key in the 7th line of the filevlogger/planning_utils/gpt4_utils.py
Run the following command to get the vlog:
python sample_scripts/vlog_read_script_sample.py- The generated scripts will be saved in
results/vlog/$your_story_dir/video.
Run the following command to get the (T+I)2V results:
python sample_scripts/with_mask_sample.py- The generated video will be saved in
results/mask_no_ref.
Run the following command to get the (T+I+Ref)2V results:
python sample_scripts/with_mask_ref_sample.py- The generated video will be saved in
results/mask_ref.
You may modify configs/with_mask_sample.yaml to change the (T+I)2V conditions and modify configs/with_mask_ref_sample.yaml to change the (T+I+Ref)2V conditions.
For example:
-
ckptis used to specify a model checkpoint. -
text_promptis used to describe the content of the video. -
input_pathis used to specify the path to the image. -
ref_pathis used to specify the path to the reference image. -
save_pathis used to specify the path to the generated video.
