WalkthroughThis update integrates "videodb" as a supported engine across multiple agents, including audio generation, dubbing, image generation, subtitle translation, web search, text-to-movie, and video generation. The VideoDBTool is extended with new media generation, dubbing, search, and transcript translation methods. Parameter schemas and control flows are revised to accommodate engine selection, and the Changes

81-88: Minor: unnecessary wrapper & default duration inconsistency
VideoDBSearchToolis a one-line proxy aroundVideoDBTool.youtube_search.
Instead of instantiating an extra class every run, you could reuse the
existingVideoDBTooldirectly, reducing object churn and keeping a single
source of truth.If you keep the wrapper:

💡 Verification agent
❓ Verification inconclusive
Silent fallback from “serp” to “videodb” may surprise callers
If the caller explicitly passes engine="serp" but no SERP_API_KEY is set, the
code quietly switches to VideoDBSearchTool.
This breaks the principle of least astonishment: the user asked for SerpAPI, but
gets completely different results without being told.
Consider one of the following:
- Raise an error when
engine == "serp"and the key is missing. - Leave the silent fallback but emit a clear warning in the response or logs.
Either way, document the behaviour in the JSON schema.
Clarify fallback behavior for missing SERP_API_KEY
When engine="serp" but no SERP_API_KEY is set, the code silently falls back to VideoDBSearchTool, which can be surprising. Please update as follows:
- In backend/director/agents/web_search_agent.py (lines 119–129):
- If
engine == "serp"andSERP_API_KEYis unset, raise a clear error (e.g.,ValueError("SERP_API_KEY is required for ‘serp’ engine")). - Alternatively, keep the fallback but emit a warning (via logging or in the response) indicating that VideoDBSearchTool is used due to the missing key.
- If
- Update the JSON schema documentation to explicitly describe this behavior and its requirements.

translate_transcript() may return None or an unexpected schema depending on
server errors. add_subtitles_using_timeline assumes a list of dicts with

24-24:⚠️ Potential issueSUPPORTED_ENGINES list needs to be updated.
You've added "videodb" to the engine enum in

The current implementation restricts job types to specific engines:
- "sound_effect" only with "elevenlabs"
- "create_music" only with "beatoven"
- "text_to_speech" only with "elevenlabs"
Yet the engine description at line 35-37 states that "videodb" supports all three job types. You need to update these conditions to allow "videodb" for these job types.

9-9: Good addition of the VideoDB tool imports.The import of

22-22: Correctly updated the supported engines.Good job adding "videodb" to the
SUPPORTED_ENGINESlist. This enables the engine validation check later in the code.
33-35: Appropriate engine description and default updates.The description now provides clear guidance on when to use which engine, and setting "videodb" as the default is consistent with the broader VideoDB integration across agents.
44-44: Clear documentation of feature limitations.Good clarification that image-to-video is only supported by "fal" engine, not by "stabilityai" or "videodb". This prevents potential misuse.

🧩 Analysis chain
Verify voice name mapping functionality.
The text_to_speech method uses VOICE_ID_MAP.get(config.get("voice_id")) to map voice IDs to voice names. This assumes that:
- The
configdictionary contains a "voice_id" key - The
VOICE_ID_MAPcontains the corresponding voice name
Let's verify this by checking what happens if the voice ID is not found in the map.
🏁 Script executed:
#!/bin/bash
# Check how VOICE_ID_MAP is defined and how it handles missing keys
# Find the definition of VOICE_ID_MAP
rg -A 5 "VOICE_ID_MAP" --glob "*.py"
# Check how VDBAudioGenerationTool.text_to_speech handles voice_id
cat backend/director/tools/videodb_tool.py | grep -A 10 "text_to_speech"Length of output: 2332
Ensure voice_id is provided and valid before calling generate_voice.
Currently, VOICE_ID_MAP.get(config.get("voice_id")) will return None if the key is missing or invalid, which may lead to unexpected errors deep in the TTS client. Explicitly validate and fail fast:

+ )
+ audio = self.collection.generate_voice(

In backend/director/tools/videodb_tool.py around line 549, the code uses
VOICE_ID_MAP.get(config.get("voice_id")) which can return None if the voice_id
is missing or invalid, potentially causing errors later. To fix this, add
explicit validation before calling generate_voice: check if "voice_id" exists in
config and if VOICE_ID_MAP contains that voice_id; if not, raise a clear error
or handle the case gracefully. This prevents passing None as voice_name and
ensures fail-fast behavior with informative error messages.

Improve content type validation and error handling in video download
The _download_video_file method has a few issues:
- The content type check is too strict - not all video content types start with 'video/'. Some CDNs or servers might return 'application/octet-stream'.
- The method returns False on error, but the calling method doesn't check the return value, only if the file exists.
def _download_video_file(self, video_url: str, save_at: str) -> bool:
os.makedirs(DOWNLOADS_PATH, exist_ok=True)
try:
response = requests.get(video_url, stream=True)

In backend/director/tools/videodb_tool.py around lines 486 to 504, improve the
content type validation by allowing common fallback types like
'application/octet-stream' in addition to those starting with 'video/'. Also,
enhance error handling by raising exceptions instead of returning False, so
calling methods can properly handle failures rather than relying solely on file
existence checks.

In backend/director/tools/videodb_tool.py around lines 405 to 417, the
generate_voice method lacks validation for the voice_name parameter. Add a check
at the start of the method to ensure voice_name is not None, and raise an
appropriate exception or handle the error if it is None before proceeding to
call the API.

Because the function never uses the save_at path, throwing an exception when the path is missing only disrupts the user’s workflow. It’s safe to drop that conditional block entirely.

346-351: Clean wrapper method for transcript translation.The method provides a clear interface for translating video transcripts with optional additional notes.
353-358: YouTube search functionality implemented correctly.Good parameter mapping and clean interface for YouTube video searches.
360-372: Dubbing method returns comprehensive metadata.The method properly structures the response with all relevant video information after dubbing.
374-426: Media generation methods provide consistent interfaces.All the new generation methods (
generate_image,generate_music,generate_sound_effect,generate_voice,generate_video) follow a consistent pattern and return structured metadata.
481-484: VDBVideoGenerationTool initialization is well-structured.Clean initialization pattern that properly sets up both the tool and collection references.
