How Arknox Times Quizzes and Forms Inside a YouTube Video
What actually happens when a video hits your overlay's timestamp
Every overlay you add in Arknox — a quiz, a poll, a lead form, a booking widget, a CTA card — is stored with a start time and, optionally, an end time. As the video plays, Arknox watches the player's own playback clock. The instant it crosses your overlay's start time, the overlay fires: video pauses (for question, form, poll, and booking types) or the overlay renders on top without interrupting playback (for lightweight CTA-style types). There's no separate polling loop checking "are we there yet" every second — it's tied directly to the player's native timeupdate event, so the trigger fires the same frame the timestamp is crossed, not up to a second late the way a coarse interval-based check would.
Two overlay behaviors, not one
Arknox's overlay types split into two groups that behave differently:
Pausing overlays — quizzes, forms, polls, booking widgets, share gates, and full-screen media cards — stop playback the moment they trigger. The viewer has to act (answer, submit, dismiss) before the video resumes. This is the group you use when you need a real response, not just a glance.
Non-pausing overlays — CTA cards and lightweight prompts — render on top of the still-playing video without interrupting it. Use these for a "learn more" link or a soft nudge that shouldn't break someone's viewing flow.
You choose which behavior a given overlay uses when you set its type — there's no separate "pause mode" toggle to configure.
Gated content can't be scrubbed past
If you mark a question as required, Arknox tracks the furthest point a viewer has actually watched. If they try to drag the seek bar past that point — to skip a quiz they don't want to answer — Arknox snaps the playhead back to where they left off. This only applies to overlays you've explicitly gated; optional overlays never restrict seeking. It's a real behavioral difference from just placing a quiz in the video and hoping people don't scrub past it.
Wrong answers can rewind the video, not just show an error
For quiz questions, you configure what happens on a wrong answer per-question:
- Allow continue — show feedback, let the viewer proceed anyway.
- Rewind — jump playback back to a specific timestamp you choose (say, the part of the video that actually explains the answer) and let them rewatch before retrying.
- Retry limit — cap how many attempts a viewer gets before the question resolves.
Why this doesn't cost what the competitors do
None of the above requires re-hosting your video. Arknox wraps YouTube's existing player and hosting — YouTube's CDN, YouTube's bandwidth, YouTube's global delivery — and adds the overlay and analytics layer on top. That's the entire reason the pricing gap is this large:
| Tool | Hosting model | Starting price |
|---|---|---|
| Arknox | Uses your existing YouTube hosting | ₹49 (~$0.59) one-time, 20 embeds, credits never expire |
| Wistia | Re-upload to their own hosting | $79/mo, billed annually |
| Vidyard | Re-upload to their own hosting | $59/user/mo, billed annually |
| Mindstamp | Re-upload to their own hosting | $99/mo |
The other three all charge you to store and stream video they're hosting for you — that's most of what a recurring monthly fee is paying for. Since Arknox never takes your video off YouTube, there's no hosting cost to pass on, and no reason to charge a recurring seat fee for it. You pay once per embed link, and that credit doesn't expire.
What this doesn't do (yet)
To be direct about the current limits: there's no true multi-path branching where a viewer's answer changes which video segment plays next (Mindstamp does this) — Arknox's rewind behavior jumps to a fixed timestamp you set, not a dynamically chosen path. And overlay positioning is template-based, not a full drag-and-drop canvas editor. If either of those is a hard requirement, it's worth knowing before you commit.
