Video Cutter Use Cases
Frequently Asked Questions
Q. Is it possible to cut video without re-encoding?
Yes. By enabling "Keyframe Snap" mode, you can cut based on I-frames for lossless extraction in seconds without quality loss.
Q. Are there any limits on video length or file size?
It depends on your device's RAM. For 4K videos longer than 30 minutes, 8GB of RAM or more is recommended. If insufficient, we suggest reducing the resolution first.
Q. Will the audio sync be affected?
No. The original audio stream is maintained, and multi-language tracks and metadata are accurately preserved in sync.
Q. Can I cut multiple segments at once?
Yes. You can add multiple segments on the timeline and save each as an individual file or export them merged into one.
Q. Are subtitle files (.srt) cut as well?
External subtitle files are not supported. Subtitles already hard-burned into the video will be cut along with the video pixels.
🎬 Keyframe Snap vs. Precise Cut Principle Comparison
I-Frames are key frames containing complete image data. Keyframe Snap moves to the nearest I-Frame for instant, lossless cutting without re-encoding.
| Mode | Quality | Speed |
|---|---|---|
| Keyframe Snap | 100% Original (Lossless) | Very Fast (Seconds) |
| Precise Cut | Re-encoding occurs (Minor loss) | Normal (Requires encoding) |
💡 Recommendation: Choose "Keyframe Snap" for general segment extraction, and "Precise Cut" for editing where frame-level precision is critical.
