FAQ
Quick answers about planning short-form compilation length.
How many clips do I need for a 30 second Reel?
Divide your target length by your average clip length. With ~3 second clips and no gaps, a 30s compilation usually needs about 10 clips. Use this planner to adjust for your real clip lengths and any transition gaps.
Does this tool require an account?
No. The Reel Length Planner runs entirely in your browser with no signup. When you are ready to assemble real clips into a vertical MP4, you can try ReelWorkshop editing free and export finished files on Starter.
Should I leave gaps between clips?
Optional. Many tight compilations cut clip-to-clip with no pause. If you add a short transition or beat gap (for example 0.3–0.5s), the planner subtracts that time so your clip count still fits the target.
What lengths work best for TikTok and Instagram Reels?
15s, 30s, and 60s are common compilation targets. Shorter hooks often perform better early; longer cuts work when each clip earns its seconds. Plan the count first, then assemble and trim in an editor.
Can ReelWorkshop build the compilation after I plan it?
Yes. Import your own clips, arrange and trim the sequence, and preview in the browser for free. Finished MP4 export is on Starter at $19.99/mo — edit and preview stay free.
