2. Video Aspect Ratio Preview
Publishing content across multiple platforms? Each has its own preferred aspect ratio. Our Video Aspect Ratio Preview tool shows exactly how your video will look when cropped for different platforms—before you spend time editing.
Supported Aspect Ratios
- 16:9 (YouTube/Landscape): Standard widescreen format
- 9:16 (TikTok/Reels/Shorts): Vertical video format
- 1:1 (Instagram Square): Perfect for feed posts
- 4:5 (Instagram Portrait): Maximum feed visibility
- 4:3 (Classic): Traditional TV format
- 21:9 (Cinematic): Ultra-wide movie format
Why This Matters
Imagine spending 2 hours editing a video for YouTube, only to realize your subject's head gets cut off when cropped for TikTok. With the Aspect Ratio Preview tool, you can identify these issues before you start editing, saving hours of rework.
3. Video Frame Screenshot Tool
Sometimes you need precise control over frame extraction. The Video Frame Screenshot tool offers frame-by-frame navigation and high-resolution capture.
Key Features
- Frame-by-frame navigation: Move forward or backward one frame at a time
- Timestamp display: See exact timecode for each frame
- High-resolution capture: Extract frames at original video quality
- Multiple export formats: PNG for quality, JPG for smaller files
Perfect For

4. Video Loop Section Preview
The Video Loop Section Preview tool is perfect for reviewing specific portions of your video repeatedly. Set start and end points, and the tool will loop that section continuously.
Key Features
- Precise time selection: Set exact start and end points down to the second
- Speed control: Slow down to 0.25x or speed up to 2x
- Quick presets: 5s, 10s, 30s, 1min loop presets
- Loop counter: Track how many times you've reviewed a section

Use Cases
- Video editors: Review transitions and cuts repeatedly
- Dance/fitness creators: Practice choreography from reference videos
- Gaming creators: Analyze gameplay moments for commentary
- Musicians: Study technique from performance videos
🎯 Workflow Tip: When reviewing your own content, loop problem sections at 0.5x speed to catch issues you might miss at normal playback. This is especially useful for spotting audio sync problems or brief visual glitches.
5. Video Metadata Viewer
Before publishing, smart creators check their video metadata. The Video Metadata Viewer reveals technical information that affects playback, compatibility, and even SEO.
What You'll Learn
- Resolution: Confirm your export settings (1080p, 4K, etc.)
- Frame rate: Verify 24fps, 30fps, or 60fps
- Codec: Check H.264, H.265, or other compression formats
- File size: Ensure it's under platform upload limits
- Duration: Confirm exact video length
- Audio specs: Bitrate, channels, sample rate
Why Metadata Matters
Different platforms have different requirements. YouTube supports 4K at 60fps, but TikTok might re-encode your video. Instagram has strict length limits. Knowing your video's technical specs helps you:
- Avoid upload failures due to incompatible codecs
- Identify why a video looks blurry on certain platforms
- Optimize file size for faster uploads
- Troubleshoot audio sync issues
Bonus: Video Playback Speed Controller
While reviewing reference content, use our Video Playback Speed Controller for precise speed adjustments from 0.25x to 4x, with pitch preservation for natural-sounding audio at any speed.
Building Your Content Creation Workflow
Here's how these tools fit into a typical content creation workflow:
Pre-Production
- Use Aspect Ratio Preview on reference footage to plan your framing
- Review tutorials with Loop Section Preview at variable speeds
Post-Production
- Check export quality with Metadata Viewer
- Review edits using Loop Section Preview
- Preview cross-platform crops with Aspect Ratio Preview
Publishing

Privacy: Your Content Stays Yours
All five tools process your videos entirely in your browser. This means:
- No uploads: Your video never leaves your device
- No waiting: Instant processing without server queues
- No file limits: Process files of any size your browser can handle
- No accounts: Use immediately without registration

⚠️ Important for Creators: Many online video tools upload your content to their servers. This creates risks for unreleased content, brand partnerships with NDAs, or simply private personal videos. Our browser-based approach eliminates this concern entirely.
