Tool Limitations & Fixed Assumptions
Platform limits are hardcoded — YouTube Shorts (60s), Instagram (90s), TikTok (10m), X/Twitter (2m20s), LinkedIn (10m). These are approximate, platform-enforced maximums as of mid-2024 and may change without notice. Always verify with the platform before publishing.
Maximum single session total: 99 hours, 59 minutes, 59 seconds. Values beyond this will display but are not designed for edge cases beyond that.
No data is saved between sessions. Refreshing the page clears all clips. There is no export, save, or sync feature.
MM and SS fields only accept 0–59. Values outside this range are rejected in place. If you need to enter e.g. 90 seconds, use 1 minute 30 seconds instead.
Bulk paste accepts whole seconds only. Sub-second precision (e.g. 1:23.456) is not supported — fractional values are ignored.
"Copy Runtime" requires browser clipboard permission. If your browser blocks clipboard access, the button shows a fallback message so you can copy manually.
