Storyboard Frame Counter
Plan shot counts, frames per shot, and per-shot duration for any AI video sequence.
Why Plan Frames Before You Generate
AI video models charge per generation, not per shot. Planning a 24-second sequence as three 8-second clips costs less than three 16-second clips. Knowing your frame budget up front lets you allocate credits sensibly across the storyboard.
Use this calculator to plan shot count, per-shot length, and total frames before you start generating. Pair it with the Veo Prompt Builder to draft the shot prompts. Once the shots are rendered, the free video-to-GIF converter turns a clip into a quick looping preview to drop into the storyboard doc.
How AI video credit math actually works
Veo charges per second of generated video, with a 25-50% surcharge for higher resolution tiers. Kling and Pika charge per clip with a flat credit cost per generation up to a duration cap (usually 5 or 10 seconds). Runway charges per second on Gen-4 and per generation on Gen-3. The implication: a 24-second storyboard cut as three 8-second clips on Veo costs less than the same storyboard cut as eight 3-second clips on Pika, even when the total runtime is identical. This calculator helps you reason about that tradeoff before you spend the credits.
A useful rule of thumb: budget 30% over your planned shot count for re-renders. AI video models miss the brief on the first take more often than they nail it, especially for prompts that require facial expression beats or specific camera moves. Storyboard 24 shots, budget for 32 generations. Storyboard 6 shots, budget for 8.
Pacing and shot length by content type
- TikTok / Reels / Shorts. Average shot length 1.2-2.0 seconds for high-retention edits. A 30-second TikTok is usually 15-20 shots. The first shot must land in the first 0.5 seconds to survive the swipe-away rate. Use the frame counter to budget the opener at 12 frames (0.5 seconds at 24fps) and the second shot at 24 frames (1 second).
- YouTube long-form. Average shot length 4-7 seconds for retention- optimized cuts in the educational and product-demo space. 7-15 second shots for cinematic essay format. Music video pacing varies wildly — high-energy tracks run 1.5-2.5 second shots, ballads run 6-10 second shots.
- UGC ads. Average shot length 2-3 seconds. Most performance UGC is three-act: hook (4-6 seconds, one or two shots), demonstration (10-20 seconds, six to ten shots), call-to-action (3-5 seconds, one shot). Keep the cut count low for credibility — UGC that feels over-edited reads as agency-made.
- Product demos. Average shot length 5-8 seconds. Showing the product in context, in use, and at detail level usually fits in 30-45 seconds across 5-7 shots. Don't undercount detail shots — they're the credibility carriers.
Storyboard Frame Counter FAQ
Does this tool generate the storyboard panels?
No. This tool calculates frame and second budgets from your shot list. To generate the visual storyboard panels themselves, use the Playcut studio's storyboard flow — drop the shot list, generate stills via Imagen, then animate the approved frames with Veo. This tool is the upstream math step.
Why does the framerate matter?
AI video models default to 24fps for cinematic and 30fps for social. Exporting at the wrong framerate causes choppy playback on TikTok (which expects 30fps) or smoothed-out unnatural motion on YouTube cinematic uploads (which expect 24fps). The calculator lets you compute frame counts at any framerate so the storyboard exports cleanly.
How long should a single AI-generated clip be?
On Veo 3, the sweet spot is 6-8 seconds per clip. Beyond 8 seconds, identity drift on characters becomes visible and motion gets less coherent. On Kling 2.0, the sweet spot is 5 seconds. On Pika 2.0, 4-6 seconds. For longer sequences, generate multiple short clips with consistent prompts and stitch in post.
Can I export the frame plan?
The tool exports a copy-ready text breakdown that pastes cleanly into Notion, Google Sheets, or the Playcut storyboard view. We're adding CSV export in the next update.
