Información técnica detallada sobre nuestro motor de conversión.
Cutting a video seems simple — but the technology behind it involves important concepts like keyframes, stream copy, and encoding modes that directly affect speed, quality, and precision. Understanding these helps you choose the right approach for every trimming task.
Stream copy mode (-codec copy in FFmpeg) transfers compressed video and audio data directly to the new file without any decoding or re-encoding. This means:
The only limitation: cuts snap to the nearest keyframe, so you may get a cut 0.5–2 seconds from your exact target.
Compressed video (H.264, H.265) stores most frames as differences from previous frames. Only keyframes (I-frames) contain complete frame data. A cut with stream copy must start at a keyframe — otherwise the output video would start with corrupted frames that reference missing prior data.
Most videos have keyframes every 2–5 seconds. This means stream-copy cuts are accurate to within that interval. For most social media and casual use cases, this is perfectly acceptable.
If you need cuts at an exact frame (e.g., for a sports highlight that needs to start at the precise moment of a goal), re-encode mode decodes the video to the exact frame position and then re-encodes from that point forward. This is slower (takes time proportional to clip length) but produces a cut at any arbitrary frame.
Re-encode mode uses CRF 23 H.264 by default, producing a very small quality reduction compared to stream copy.
The video cutter accepts time in HH:MM:SS format:
Duration works the same way: a duration of 0:45 means the clip will be 45 seconds long from the start point.
If you need several non-contiguous segments from one video — for example, a highlights reel from a longer recording — use the Video Cutter to extract each segment individually, then use our Video Merger to combine them into a final compilation. This two-step workflow gives you precision control over each cut without needing a full video editor.
