Shorts Upload Pack builds a YouTube Shorts–ready 9:16 deliverable: blur-pad to 1080×1920 (or 720×1280 compact), ≈ −11 LUFS, hard-trim 15–90s, Quality/Balanced/Compact CRF tiers, and optional MB cap — one browser job from an owned master.
What export settings does YouTube Shorts need?
YouTube Shorts expects a vertical 9:16 MP4 (1080×1920 recommended), H.264 video, AAC audio, and loudness that competes in swipe feeds — RepostClip Shorts Upload Pack targets ≈ −11 LUFS integrated with a 15–90s optional trim.
Spec sheet and check first:
What does a dedicated Shorts 9:16 pack change vs a landscape master?
A Shorts pack produces a 9:16 Shorts-ready pack at 1080×1920 with short-form loudness and length cap.
What this pass delivers for a Shorts pack in one pass:
- 1080×1920 blur-pad, louder short-form loudness, and a 15–90s hard trim land in one deliverable.
- Shorts-style feeds receive a vertical file without a separate vertical edit session.
- Uploading elsewhere vertical channels starts from a purpose-built file, not a landscape master.
What do vertical feeds invent when the frame is wrong?
Without the pack, vertical feeds invent landscape or quiet masters uploaded into feeds that expect vertical.
What landscape uploads force Shorts, TikTok, and Reels to invent:
- Apps invent crops and loudness — often badly — before anyone finishes the open.
- Multiple half-finished vertical exports replace one Shorts pack.
- Time-to-post slips when each short-form app requires a different last-minute fix.
How do Shorts-ready framing and loudness relate to feed playback?
Native 9:16 delivery is native vertical framing plus short-form loudness for Shorts, TikTok, and Reels.
How short-form discovery surfaces treat vertical delivery:
- Vertical feeds are where most discovery happens for short clips; a true 9:16 file matches that surface.
- Short-form loudness keeps the open audible against the previous video’s volume in the swipe feed.
- When framing and audio land cleanly, completion rate has a clearer path — and completion fuels push.
- Without the pack, auto-crop and auto-gain decide how the clip displays.
A Shorts pack is 1080×1920 with short-form loudness; shelf placement still tracks retention after playback starts.
When do creators use the Shorts upload pack?
Creators use the Shorts upload pack when a landscape or mixed master must become a vertical 9:16 deliverable with loudness suited to short-form feeds in one encode pass.
Can landscape video become YouTube Shorts in one job?
Yes — Shorts Upload Pack blur-pads landscape 16:9 into 9:16, applies −11 LUFS, and trims length in one job. Use Vertical Video Converter or Fit to Aspect first only when you need canvas-only output without loudness or length baked in.
Canvas-only vs full pack:
How does the Shorts pack build a 9:16 deliverable?
The Shorts pack maps the source into a 9:16 blur-pad canvas sized by encode tier, applies short-form loudness, strips leaky metadata, and encodes H.264/AAC at the chosen CRF — or ABR toward an optional MB cap when set.
Typical Shorts pack stages:
- Compute pad offsets for 9:16 (1080×1920 or compact 720×1280).
- Fill letterbox/pillar regions with blurred source (not black bars).
- Normalize loudness toward short-form ≈ −11 LUFS.
- Encode H.264/AAC at Quality/Balanced/Compact CRF, or ABR to an optional MB cap.
When should creators enable the optional MB size cap?
Enable the MB size cap when Discord, DM, or upload limits need a concrete file size while keeping Shorts 9:16 framing and −11 LUFS — leave it off to use encode tiers only.
Size-only alternative:
How does Shorts pack differ from the Reels / TikTok pack?
Shorts pack defaults to CRF encode tiers for YouTube Shorts-style delivery; Reels / TikTok pack defaults to ABR bitrate tiers — both share optional MB caps and 9:16 framing for the same owned master.
When do creators skip the Shorts pack?
Creators skip the Shorts pack for long-form 16:9 YouTube uploads or square Instagram grid posts and use YouTube pack or the square converter instead.
