Technical Limits and Trimming Methodology
Viditok's online video trimmer lets you cut and trim video clips directly in your browser using our dedicated server-side FFmpeg pipeline. To ensure stability and prevent server congestion for all creators, this tool enforces two transparent operational boundaries: uploaded video files must not exceed 50 megabytes (50 MB) in total size, and clips are capped at a maximum length of 2 minutes (120 seconds). Videos exceeding these thresholds are rejected before encoding begins. By default, trimming runs in ultra-fast stream copy mode, which isolates your selected segment in less than a second without re-compressing video frames. Because stream copy cuts on keyframe boundaries, the cut point aligns with the nearest keyframe in your source clip. If your project demands millisecond-level precision at the exact start and end timestamps, enable the “Precise cut” toggle. This option re-encodes the segment using the veryfast x264 profile to deliver a smooth cut at the exact frame you selected. All uploaded source media and exported files are processed in ephemeral scratch storage and automatically pruned within 15 minutes.
