Frequently Asked Questions
Why is trimming so fast?
The trimmer uses ffmpeg's stream copy mode (-c copy), which copies the video and audio data without decoding or re-encoding. The only work is reading the container, copying the relevant packets, and writing a new container. This makes it orders of magnitude faster than re-encoding.
Are the cuts frame-exact?
Stream copy mode cuts at the nearest keyframe (I-frame). For most videos encoded with keyframes every 1–2 seconds, the cut point will be within a second of your requested time. If you need frame-exact cuts, you would need to re-encode the video, which our Video Converter can help with.
Can I trim very large video files?
Yes, but keep in mind that the entire file must be loaded into browser memory via WebAssembly. Files up to ~2 GB work well on most modern machines with 8+ GB RAM. For very large files, the loading step may take a moment, but the actual cutting is still fast.
Does trimming add a watermark?
No. The output is an exact copy of the original video data — nothing is added, removed, or modified. There are no watermarks, logos, or branding of any kind.
