Trim Screen Recordings
Screen recordings often have messy starts, long pauses, and unnecessary endings. Trim your OBS, Loom, Teams, or any screencast to just the parts that matter - without re-encoding or quality loss.
Common Screen Recording Formats Supported
Why Trim Screen Recordings?
Remove Setup Time
Cut the "let me just..." at the beginning when you're getting ready.
Skip Dead Time
Remove loading screens, pauses, and "um" moments.
Focus on the Demo
Keep just the part that shows what you're demonstrating.
Reduce File Size
Shorter video = smaller file for easier sharing.

By Recording Tool
OBS Studio
OBS records to MKV by default. JustTrimVideo handles MKV files natively - no conversion needed. Great for streaming highlights and let's play clips.
Loom
Download your Loom as MP4, then trim to remove intros or rambling. Perfect for tightening async video messages.
Microsoft Teams / Zoom
Meeting recordings are often hours long. Extract just the 5-minute segment you need to share.
Windows Game Bar / macOS Screenshot
Quick captures often have extra seconds at start/end. Clean them up before sharing.
ShareX / Snagit
Professional screen capture tools output clean formats that trim perfectly.
Common Use Cases
Software Tutorials
Record the whole flow, then trim to just the steps that matter.
Bug Reports
Show developers exactly the bug, not 5 minutes of setup.
Training Videos
Create bite-sized clips from longer training sessions.
Gaming Highlights
Extract clutch moments from long OBS recordings.
Tip: OBS MKV Files
OBS records to MKV to prevent file corruption if the recording crashes. Most tools require you to remux to MP4 first. JustTrimVideo handles MKV directly - just load and trim.
