Platform cutdowns
Vertical Cutdowns in Premiere Pro with MCP: Reframe, Safe Zones, Deliver
Plan multi-ratio Premiere deliveries, auto-reframe sequences, check caption safe zones, and preflight exports for Shorts, Reels, TikTok, and YouTube with MCP tools.
Plan the delivery matrix before reframing
plan_platform_delivery_matrix plans multi-ratio delivery of one source sequence to TikTok, Reels, Shorts, YouTube, LinkedIn, X, and Facebook from a local spec table. Strategies include auto_reframe, pad_blur, center_crop, and letterbox. It reports sequence settings, reframe scale math, duration and file-size fit, caption safe zones, and ordered apply routes. Local-only; it never changes Premiere.
create_editorial_plan with workflow platform_cutdown can also produce an evidence-backed plan from captured context without mutating the host.
Plan a platform delivery matrix from my approved horizontal master for Shorts, Reels, and TikTok using strategy auto_reframe. Show safe-zone and duration fit notes. Do not reframe or export yet.Auto-reframe into a new sequence
auto_reframe_sequence creates a new sequence at target_width x target_height with motion presets slower, default, or faster. Premiere derives an intermediate size from the source height; the tool then sets the requested frame size and verifies it so the Auto Reframe effect refits to the new size.
Review the reframed sequence in the Program Monitor. Motion tracking quality is host-dependent; still exports help spot framing issues but do not prove continuous motion.
Check overlays and captions for platform UI
check_caption_safe_zone tests caption, title, logo, and graphic rectangles against approximate platform UI overlay zones and suggests the nearest clear position. Supply normalized rects; the tool never reads Premiere state.
If you import captions on the vertical sequence, follow the captions workflow: build or retime the artifact, import with create_caption_track, then style manually using get_caption_style_guidance.
Preflight and export with evidence
validate_project_for_export runs a non-mutating export preflight for offline media, empty timelines, preset/output paths, duration, and optional gaps. readyForExport means those checks passed; it does not prove the encoder will finish.
export_sequence renders with an Adobe Media Encoder preset and verifies a non-empty file plus duration within one sequence frame when ffprobe is available. Follow with verify_delivery_file and, when you have an explicit contract, verify_delivery_conformance. analyze_loudness measures LUFS on a local file without normalizing audio.
- Refuse existing output paths unless you intentionally overwrite.
- Match the output extension to the .epr preset’s real container.
- Keep platform duration and file-size limits in the plan you reviewed.
Questions editors ask
Does plan_platform_delivery_matrix create the vertical sequences?
No. It plans routes and fit checks. Creating reframed sequences and exports are separate reviewed steps.
Is auto-reframe available on every Premiere install?
The tool is in the default profile catalog, but host Auto Reframe behavior and quality remain Premiere-version and media dependent. Verify the new sequence size and framing yourself.
Can MCP guarantee TikTok safe zones?
check_caption_safe_zone uses approximate overlay geometry you supply. Platform UI changes; always spot-check on-device when the delivery matters.
