Caption Preset Editor, AI Style Generation & Best Take Selector

What's New

• A brand-new split-view caption preset editor lets you design caption styles across 13 grouped settings (font, size, position, animation, and more) with a live preview updating as you make changes.
• AI can now generate or remix a caption style for you — describe what you want and the AI produces a ready-to-use preset, which appears in a dedicated 'AI Drafts' section on the My Styles page.
• You can now import custom fonts directly into your caption styles by pasting a URL to a TTF, OTF, or ZIP file, or by searching and adding fonts from Google Fonts.
• Every caption preset now shows a visual thumbnail preview on the My Styles page, so you can tell styles apart at a glance without opening each one.
• A new Best Take Selector automatically analyses repeated takes of the same line and picks the strongest one, surfacing its reasoning and the source of the decision directly in the repetition groups panel.
• A two-panel Transcript Review screen lets you read and edit your transcript on the left while scrubbing the timeline on the right before generating captions — with a sticky 'Review & Generate' button always in reach.
• The My Styles page has been redesigned with a new toolbar, a horizontal tile layout, and a delete button anchored to each style card for quicker management.

Improvements

• Caption preset previews are now generated and stored when you create or update a preset, and loaded directly from a pre-signed URL — no more waiting for multiple parallel preview requests.
• The Best Take Selector falls back to a fast rule-based picker if the AI is unavailable, so you always get a result even without a live AI connection.
• The AI style generator and remixer now use your actual installed font list, so every suggested style uses a font you already have available.
• API retry limits have been raised and errors are now categorised more precisely, reducing failed caption jobs caused by transient network issues.
• The caption bounding-box overlay now stays visible even when text measurement isn't available, using a safe fallback size.
• Dragging, resizing, and rotating caption boxes is now more reliable — input is read from a stable reference rather than a stale snapshot, eliminating race conditions.
• The caption canvas height is capped at 50 % of the viewport and the font Size slider is capped at 200, preventing the editor from breaking its own layout.
• The redundant Position accordion has been removed from the preset editor, and common actions are now reachable in one click.
• The /dashboard/download URL now correctly redirects, and all affected links have been retargeted so the download page is always reachable.

Bug Fixes

• Fixed bounding-box handles being blocked by an invisible canvas wrapper element — you can now drag and resize caption boxes freely.
• Fixed captions bleeding outside the preview canvas area by restoring the correct overflow clipping on the canvas container.
• Fixed a bug where browser-native image dragging interfered with moving caption boxes inside the editor.
• Fixed the My Styles page not immediately reflecting when a preset is activated, duplicated, or deactivated — the UI now updates instantly without requiring a refresh.
• Fixed the cost-ceiling error message that was leaking internal dollar amounts — the message is now user-friendly with no internal figures exposed.
• Fixed a stale broadcast in the server-side rendering path that could cause incorrect data to appear after a page refresh.
