Pre-flight video validator for webinar presenters

The moment a presenter realizes their video isn't playing is always the worst possible moment — in front of a live audience, with no recovery path. They assumed it would work because it worked in rehearsal, or because the file plays fine on their desktop. Nobody told them that streaming a 400MB MP4 through a screen-share pipeline would buffer and die after 90 seconds.

This gap persists because conferencing vendors have no incentive to warn you. Their product 'works' — the failure is attributed to your file, your connection, your browser. The bug report gets closed as user error. Meanwhile the actual user — a corporate trainer, a marketing webinar host, a professor — quietly learns to never include video again, which is exactly what multiple reviewers said they did.

What's missing is a tool that runs before the meeting, not during it. You drop in your presentation file or video files, specify which conferencing product you're using and roughly how many attendees you expect, and it tells you: this video will fail, here's why, here's a fixed version. The specific problems it catches are the ones users keep hitting — files too large to stream without buffering, codecs that silently fail inside browser-based players, animations embedded in PPTX that won't survive a screen-share render, audio tracks that get dropped when video is shared over certain protocols.

No existing pre-meeting checklist tool does this at the file level. They test your mic and camera. Nobody is testing whether your actual content will survive the session.

This is a business because the pain recurs every single time someone prepares a new presentation with video. Corporate trainers run monthly sessions. Demand gen teams run weekly webinars. Each new file is a fresh risk. The cost of getting it wrong isn't just embarrassment — it's a recorded session with dead air that becomes a broken on-demand asset, a sales webinar that loses the room at the product demo, a training module that fails compliance completion tracking.

What to build

Build a browser-based pre-session checker where presenters upload their PPTX or video files, select their conferencing tool, and receive a per-file report flagging codec incompatibilities, file size thresholds that cause buffering, and animation elements that won't render — along with auto-converted versions that will.

Where to start

Start with PPTX files destined for Adobe Connect specifically, since Adobe Connect's video pod behavior is well-documented and consistently broken in ways you can map precisely — giving you a tight, demonstrably accurate first use case before expanding to other platforms.

The hard part

Each conferencing product handles video rendering differently, so the compatibility rules for Adobe Connect are not the rules for Chime — maintaining an accurate, tested matrix of failure conditions per platform requires ongoing QA work that doesn't scale cheaply.

How it makes money

Per-seat annual subscription targeting webinar coordinators and L&D teams, priced around $15–25/month per user; free tier allows one file check per month to drive word-of-mouth inside marketing and training orgs.
