How to Trim Video and Audio by Timecode with fal‑ai’s Trim Utility
Editing media often involves cutting specific sections quickly and accurately. fal‑ai’s Trim Utility lets you trim video or audio files by specifying start and end timecodes, so you no longer need to scrub long timelines.
Why Precision Matters
When working with long recordings, even a few frames off can disrupt flow. Precise, timecode‑based trimming ensures cuts are frame‑accurate, keeping content tight and professional.
About fal‑ai’s Trim Utility
This cloud‑based tool takes a publicly accessible media URL and timecodes. It then produces a new file that contains only the requested segment. Because it is part of fal‑ai’s AI workflow suite, you can use it in scripts or applications without heavy software.
Timecode Basics
Timecode labels specific frames in a media file. The standard SMPTE format, HH:MM:SS:FF, gives each frame a unique address. This lets editors reference exact points across different tools.
Step‑by‑Step Guide
- Find Your Media URL
Find a publicly reachable media URL. Pass it in thevideourloraudiourlparameter. - Define Start and End Timecodes
Define start and end timecodes. Use either seconds (e.g., 60.5) or HH:MM:SS (e.g., 00:01:30). Accuracy at this step determines trim quality. - Prepare the API Request
Prepare the API request. Create an HTTP POST to the trim endpoint. Include your API key, media URL, start, and end parameters. - Send the Request
Send the request. fal‑ai processes the media in the cloud. - Receive the Trimmed File
A URL to the new file is returned. Download or use it directly in your workflow.
Key Parameters
videourloraudiourl– Direct link to the source media.starttime– Beginning point (seconds or HH:MM:SS).endtime– Ending point (seconds or HH:MM:SS).

Integrating Into Advanced Workflows
Because the Trim Utility is API‑driven, it can be combined with other services such as transcription, captioning, or sentiment analysis. Batch scripts can process many files simultaneously, which is useful for agencies or large content libraries.
Technology Overview
Internally, the utility likely relies on libraries like FFmpeg to perform precise cuts. When start and end points align with keyframes, it can copy the stream without re‑encoding. If re‑encoding is required for frame accuracy, the service handles this efficiently in the cloud.
Best Practices
- Identify timecodes accurately using a reliable video player or transcript.
- Test on a small segment before trimming a large file.
- Integrate the API into your development environment for automation.
FAQ
What is timecode?
Timecode assigns a unique address (HH:MM:SS:FF) to each frame. This enables precise cuts and synchronization.
How does the Trim Utility compare to manual editing?
It automates frame‑accurate trimming. Consequently, it reduces manual guesswork and speeds up bulk operations.
Can I trim video and audio together?
Yes. Provide a videourl to trim both tracks simultaneously. Alternatively, use an audiourl if you need only audio.
What formats are supported?
The service accepts common video and audio formats. It also handles the underlying codec conversion automatically.
