Prompts

The instruction Splice sends the AI for every clip — and how to tune it.

What’s a prompt?#

A prompt is the written instruction Splice hands the AI before it looks at your clip. Think of it like the system prompt in ChatGPT — it tells the AI exactly what to look for. Without it, the AI would have no idea whether you’re playing Valorant or Rocket League, or whether a “highlight” means a kill, a clutch round, or an epic save.

Splice ships with default prompts tuned for each supported game. The Valorant default tells the AI to watch the top-right killfeed (with its distinctive purple/orange text), the skull icon next to confirmed kills, and ability-kill markers like Raze’s ult or Sova’s dart — and to ignore round-end banners, scoreboard screens, and agent select. The Counter-Strike default points at the top-right killfeed, the headshot icon, and the HUD kill counter ticking up. These defaults were written specifically because vague instructions produce bad results.

Recall vs. precision — pick your side#

When you tune your prompt, you’re making a tradeoff between two things:

• More recall — Splice finds more clips, but some won’t be actual highlights. Use this if you’d rather skim a bigger batch and delete the misses yourself.
• More precision — Splice only saves clips it’s confident about, so you might miss a few real moments. Use this if you want a tight, clean folder you can share right away.

Loose language like “anything that looks exciting” pulls toward recall. Tight language like “eliminations confirmed by a kill chip on the right side of the screen” pulls toward precision. Neither is wrong — it depends on how you play and how much you want to review.

How to edit your prompt#

1. Open Splice and click Models in the sidebar.
2. In the Game Configurations section, click the game’s card to expand it.
3. Scroll to the Detection Prompt section near the bottom and click Edit.
4. Edit the text in the textarea, then click Save Changes.

The next time Splice runs analysis on that game, it’ll use your updated instruction. You can always paste the original back in if a change makes things worse.

The Buffer Before and Buffer After number inputs sit on the same expanded card, just above the Detection Prompt. These control how many seconds of footage appear before and after each detected moment in your highlight. Three to four seconds before and two to three seconds after is a solid starting point for most shooters.
