SubStyle — Caption Style Preview Tool for Video Editors
Why This is an Opportunity
This is basically a visual config tool — image upload, text overlay with CSS controls, and a PDF/image export. No video processing needed at all since you're working with a static frame.
Key Pain Points
- •Previewing caption styles means rendering a 30-second clip every single time you change a font or color
- •You can't easily see how captions look on a phone screen when you're editing on a 27-inch monitor
- •Every new client wants a 'branded caption style' and you start from scratch each time with no saved presets
- •Sharing caption style options with clients for approval means recording screen captures of each variation
Original Discovery
Video editors spend forever tweaking caption fonts, colors, animations, and positioning in Premiere or DaVinci, rendering previews each time to see how they look on mobile. SubStyle lets you upload a single frame from your video, then live-preview different caption styles overlaid on it — font, size, color, stroke, position, animation type — and export the exact settings as a spec sheet for your editing software.
