Summary of Changes
Hello @katiemn, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request introduces a set of new code samples for the veo-2.0-generate-001 model, expanding the demonstration of its advanced video generation capabilities. These samples cover scenarios such as controlling video generation with specific first and last frames, generating videos from existing video inputs, and applying fine-grained controls like disabling prompt rewriting and managing person generation within the output. The changes also include the necessary test coverage for these new examples.
Highlights
- New Video Generation Samples: I've added three new Python code samples demonstrating advanced control features for video generation using the
veo-2.0-generate-001model. - First and Last Frame Control: One sample (
videogen_with_first_last_frame.py) illustrates how to generate a video by providing both an initial image and a desired last frame, guiding the video's progression. - Video-to-Video Generation: Another sample (
videogen_with_vid.py) showcases the ability to generate a new video based on an existing video input, allowing for transformations or continuations. - Fine-grained Generation Control: A third sample (
videogen_with_no_rewrite.py) demonstrates how to disable prompt enhancement (enhance_prompt=False) and control person generation (person_generation='dont_allow') for more precise output. - Automated Testing: Corresponding test cases have been added to
test_video_generation_examples.pyto ensure the functionality of these new video generation samples.

Code Review
This pull request adds new code samples for VEO advanced control features, along with corresponding tests. The new samples demonstrate generating video from first/last frames, from another video, and with prompt rewriting disabled. My review identifies a correctness issue where the samples could crash, and several issues to improve test quality and naming consistency. Addressing these will significantly improve the robustness and maintainability of the new samples.
