• Seed and prompt added to strip name.

Requirements

• Windows or Linux (Could maybe work on MacOS, but someone will have to contribute code to make it work).
• A CUDA-supported Nvidia card with at least 4 GB VRAM.

How to install

(As for Linux, if anything differs in installation, then please share instructions.)

• First you must download and install git for your platform(must be on PATH(or Bark will fail)): https://git-scm.com/downloads

• Download the add-on: https://github.com/tin2tin/text_to_video/archive/refs/heads/main.zip

• On Windows, right-click on the Blender icon and "Run Blender as Administrator"(or you'll get write permission errors).

• Install the add-on as usual: Preferences > Add-ons > Install > select file > enable the add-on.

• In the Generative AI add-on preferences, hit the "Install all Dependencies" button.

• Note that you can change what model cards are used in the various modes here(video, image, and audio).

• Then it writes that it is finished(if any errors, let me know).

• Restart Blender.

• Open the add-on UI in the Sequencedr > Sidebar > Generative AI.

• The first time any model is executed many GB will have to be downloaded, so go grab lots of coffee.

• If it says: "ModuleNotFoundError: Refer to https://github.com/facebookresearch/xformers for more information on how to install xformers", then try to restart Blender.

Tip
If any Python modules are missing, use this add-on to manually install them:

Location

Install Dependencies, set Movie Model Card, and set Sound Notification in the add-on preferences:

Se SDXL handling most of the styles here: https://stable-diffusion-art.com/sdxl-styles/

Text to Video/Image

The Animov models have been trained on Anime material, so adding "anime" to the prompt is necessary, especially for the Animov-512x model. The Stable Diffusion models for generating images have been used a lot, so there are plenty of prompt suggestions out there if you google for them. The Modelscope model has a watermark, since it's been trained on Shutterstock material, and can't be used for commercial purposes.

Tip
If the image of your renders breaks, then use the resolution from the Model Card in the Preferences.

Tip
If the image of your playback stutters, then select a strip > Menu > Strip > Movie Strip > Set Render Size.

Tip
If you get the message that CUDA is out of memory, then restart Blender to free up memory and make it stable again.

Batch Processing

Select multiple strips and hit Generate. When doing this, the file name, and if found the seed value, is automatically inserted into the prompt and seed value.

Text to Audio

Bark

Find Bark documentation here: https://github.com/suno-ai/bark

• [laughter]
• [laughs]
• [sighs]
• [music]
• [gasps]
• [clears throat]
• — or ... for hesitations
• ♪ for song lyrics
• capitalization for emphasis on a word
• MAN/WOMAN: for bias towards the speaker

Speaker Library: https://suno-ai.notion.site/8b8e8749ed514b0cbf3f699013548683?v=bc67cff786b04b50b3ceb756fd05f68c

Tip
If the audio breaks up, try processing longer sentences.

AudioLDM2

Find AudioLDM documentation here: https://github.com/haoheliu/AudioLDM Try prompts like: Bag pipes playing a funeral dirge, punk rock band playing hardcore song, techno dj playing deep bass house music, and acid house loop with jazz. Or: Voice of God judging mankind, woman talking about celestial beings, hammer on wood.

Uninstall

Hugging Face diffusers model is downloaded from the hub and saved to a local cache directory. By default, the cache directory is located at:

On Linux and macOS: ~/.cache/huggingface/transformers

On Windows: %userprofile%\.cache\huggingface\transformers

Here you can locate and delete the individual models.

Restrictions for using the AI models:

• The models can only be used for non-commercial purposes. The models are meant for research purposes.
• The models was not trained to realistically represent people or events, so using it to generate such content is beyond the model's capabilities.
• It is prohibited to generate content that is demeaning or harmful to people or their environment, culture, religion, etc.
• Prohibited for pornographic, violent, and bloody content generation.
• Prohibited for error and false information generation.
