🛠️ Refactor suggestion
Add error handling for video generation results.
Currently, the code assumes that each video generation run is successful. To prevent potential crashes, add error handling to handle failures in _run_video_generation.
for index, params in enumerate(video_generation_comparison):
res = self._run_video_generation(index, params)
+ if res.status != AgentStatus.SUCCESS:
+ logger.error(f"Video generation failed for index {index} with params {params}")
+ continue
videos_content.videos[index] = res.data["video_content"].video
self.output_message.push_update()📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🛠️ Refactor suggestion
Add error handling for API response and download failures.
Currently, the code does not handle exceptions that may occur during the API call or the video download. Consider adding try-except blocks to handle potential errors and ensure the application remains robust.
def text_to_video(self, prompt: str, save_at: str, duration: float, config: dict):
model_name = config.get("model_name", "fal-ai/minimax-video")

res = fal_client.run(
model_name,
arguments={"prompt": prompt, "duration": duration},
)
video_url = res["video"]["url"]
except Exception as e:
raise Exception(f"Failed to generate video with FAL API: {e}")
try:
response = requests.get(video_url)

Unpack both index and params from future_to_params
In line 104, you're assigning params = future_to_params[future], but future_to_params[future] returns a tuple (index, params). Ensure you unpack both variables correctly.
Apply this diff to fix the unpacking:
- params = future_to_params[future]

54-57: Handle missing name parameter gracefully
While the schema marks "name" as required, it's still retrieved using .get() which returns None if missing. This could lead to issues later when uploading or displaying the video.

The new section follows the established pattern of the file with clear section headers and consistent variable naming.
39-39: Verify proper handling of FAL_KEY environment variable.
Let's ensure the codebase properly validates and handles the FAL_KEY environment variable.
✅ Verification successful
FAL_KEY environment variable is properly validated and handled
The codebase demonstrates proper validation and error handling for the FAL_KEY:
- In
backend/director/agents/video_generation.py, the key is checked before use and raises an exception if missing - In
backend/director/tools/fal_video.py, there's additional validation in the tool initialization - The error handling follows the same pattern as other API keys in the codebase (e.g., Stability AI, ElevenLabs)

5-29: Consider extracting model configurations to a separate file.The
PARAMS_CONFIGdictionary contains a comprehensive list of models, but as this list grows, it might be better to maintain it in a separate configuration file for better maintainability.Consider creating a new file
model_config.py:TEXT_TO_VIDEO_MODELS = [ "fal-ai/minimax-video", "fal-ai/mochi-v1", # ... other models ] PARAMS_CONFIG = { "text_to_video": { "model_name": { "type": "string", "description": "The model name to use for video generation", "default": "fal-ai/fast-animatediff/text-to-video", "enum": TEXT_TO_VIDEO_MODELS, }, }, }
32-37: Consider adding API key validation.The API key validation could be more robust by checking its format or attempting a test request.
Consider adding a validation method:
def __init__(self, api_key: str): if not api_key or not isinstance(api_key, str) or len(api_key.strip()) == 0: raise ValueError("Invalid FAL API key") os.environ["FAL_KEY"] = api_key.strip() self._validate_api_key() def _validate_api_key(self): try: # Make a minimal API call to validate the key fal_client.run("fal-ai/minimax-video", arguments={"prompt": "test"}, timeout=5) except Exception as e: raise ValueError("Failed to validate FAL API key") from e

91-96: Enhance VideosContent docstringWhile the implementation is clean, consider enhancing the docstring to better describe:
- The purpose of handling multiple videos
- The relationship with VideoData objects
- Typical usage scenarios
class VideosContent(BaseContent): - """Videos content model class for videos content.""" + """Videos content model class for handling multiple video contents. + + This class encapsulates a collection of VideoData objects, typically used + for scenarios involving video comparison or batch processing. Each video + in the videos list can have its own stream_url, external_url, and metadata. + """
91-96: Consider adding validation for video comparison scenariosThe new
VideosContentclass enables video comparison functionality. Consider adding:
- Validation for the minimum/maximum number of videos allowed in the list
- Methods to facilitate video comparison operations
- Helper methods for common operations like finding differences between videos
This would make the class more robust and easier to use in comparison scenarios.

44-51: LGTM: Well-structured class initialization
The class initialization is well-documented with clear description and proper parameter setup.
52-56:
Add error handling for video generation tasks
The method should handle potential exceptions from VideoGenerationAgent to prevent crashes.
Apply this diff to add error handling:
def _run_video_generation(self, index, params):
"""Helper method to run video generation with given params"""
- video_gen_agent = VideoGenerationAgent(session=self.session)
- return (index, video_gen_agent.run(**params, stealth_mode=True))
+ try:
+ video_gen_agent = VideoGenerationAgent(session=self.session)
+ result = video_gen_agent.run(**params, stealth_mode=True)
+ return (index, result)
+ except Exception as e:
+ logger.exception(f"Error in video generation for index {index}: {e}")
+ return (index, AgentResponse(
+ status=AgentStatus.ERROR,
+ message=f"Failed to generate video: {str(e)}"
+ ))Likely invalid or redundant comment.
29-34:
Avoid using Python unpacking operators in JSON schema
The use of ** and * operators for schema property inheritance might not work as intended in JSON schema validation. Consider explicitly listing the properties.
Apply this diff to fix the schema inheritance:
- **VIDEO_GENERATION_AGENT_PARAMETERS["properties"],
+ # Explicitly list inherited properties
+ "collection_id": VIDEO_GENERATION_AGENT_PARAMETERS["properties"]["collection_id"],
+ "engine": VIDEO_GENERATION_AGENT_PARAMETERS["properties"]["engine"],
+ "text_to_video": VIDEO_GENERATION_AGENT_PARAMETERS["properties"]["text_to_video"],
+ # Add other required properties...
- *VIDEO_GENERATION_AGENT_PARAMETERS["required"],
+ # Explicitly list required fields
+ "collection_id",
+ "engine",
+ "text_to_video",
+ # Add other required fields...Likely invalid or redundant comment.
121-124:
Add timeout handling for notification queue
The while loop waiting for notifications could potentially hang if a task fails silently.
Apply this diff to add timeout handling:
+ from queue import Empty
+
while completed_count < total:
- res = self.notification_queue.get()
- self._update_videos_content(videos_content, res[0], res[1])
- completed_count += 1
+ try:
+ res = self.notification_queue.get(timeout=300) # 5 minutes timeout
+ self._update_videos_content(videos_content, res[0], res[1])
+ completed_count += 1
+ except Empty:
+ logger.error("Timeout waiting for video generation results")
+ videos_content.status = MsgStatus.error
+ videos_content.status_message = "Timeout waiting for video generation"
+ self.output_message.push_update()
+ breakLikely invalid or redundant comment.
126-135:
Improve completion status handling
The code unconditionally sets success status without checking if all video generations were successful. Additionally, the future variable in the loop is unused (B007).
Apply this diff to improve completion handling:
- for future in concurrent.futures.as_completed(futures):
- try:
- videos_content.status = MsgStatus.success
- videos_content.status_message = "Here are your generated videos"
- self.output_message.push_update()
- except Exception as e:
- logger.exception(f"Error processing task: {e}")
+ # Check if any videos failed
+ has_failures = any(
+ not video.stream_url for video in videos_content.videos
+ )
+
+ videos_content.status = MsgStatus.partial if has_failures else MsgStatus.success
+ videos_content.status_message = (
+ "Some videos failed to generate" if has_failures
+ else "Here are your generated videos"
+ )
+ self.output_message.push_update()Likely invalid or redundant comment.

86-105: 🛠️ Refactor suggestion
Add input validation before processing
The method should validate the input parameters before proceeding with video generation setup.
Apply this diff to add input validation:
try:
+ if not video_generation_comparison:
+ raise ValueError("No video generation parameters provided")
+
if job_type == "video_generation_comparison":
+ # Validate parameters before starting
+ for params in video_generation_comparison:
+ if not params.get("text_to_video") or not params["text_to_video"].get("name"):
+ raise ValueError("Invalid parameters: missing text_to_video.name")

43-43: LGTM: ContentType enum extension
The addition of the videos content type follows the established pattern and naming convention.
154-154: LGTM: BaseMessage content type extension
The addition of VideosContent to the Union type is consistent and maintains type safety.
73-74: Verify the impact of optional stream_url
Making stream_url optional and adding external_url suggests a change in video source handling. Let's verify that existing code handles the optional stream_url correctly.
✅ Verification successful
Let me gather more information about how the stream_url is used in the codebase, particularly focusing on any validation or processing logic.
Based on the gathered information, I can now generate the final response:
Making stream_url optional is safe and well-handled
The codebase already handles optional stream_url appropriately:
- Stream video agent explicitly checks for
stream_urlpresence before processing - All
VideoDatainitializations either provide astream_urlor handle empty/error cases - The addition of
external_urlcomplements existing URL handling patterns
