TRANSPARENT SPECIFICATIONS

What UploadCorrect can fix — and what it cannot.

Clear technical standards and honest capabilities for every content creator.

What UploadCorrect Can Fix

  • Editing software signatures: Purges CapCut, Lavf, Adobe Premiere, DaVinci Resolve, and InShot stamps from container atoms.
  • Privacy & GPS coordinates: Strips embedded ISO 6709 geolocation tags, latitude/longitude markers, and filming locations.
  • Fast-start web alignment: Re-orders the moov atom ahead of media payload for progressive instant social playback.
  • Device & camera metadata: Formats the container with clean QuickTime camera metadata while maintaining full file validity.
  • Lossless stream copy: Never re-encodes or degrades video frames. Video payload remains bit-for-bit pristine.
  • Audio quality & clipping audit: Web Audio API PCM analysis flags digital clipping, 48 kHz compliance, and dead air silence.
  • Safe-zone conflict warnings: Frame inspection warns if subtitles collide with platform engagement rails or caption descriptions.
  • Verified Quality Guarantee: Automated 6-point pre-release inspection generates a downloadable verification certificate.

Honest Technical Limitations

  • Aspect ratio re-shooting: If a video is recorded in 16:9 widescreen, we cannot rotate or crop it into 9:16 without altering the framing.
  • Visible watermarks: Text or logos rendered directly onto the video pixels cannot be removed without re-rendering the footage.
  • No algorithm guarantees: We do not claim to bypass TikTok view limits or guarantee viral reach. We deliver technically verified files.
  • Audio stream presence: If a source video has no audio track recorded, we do not synthesize artificial background music.
COMPLETE 2026 CREATOR PREFLIGHT SUITE

Built for TikTok Shop, Reels, Shorts & High-Volume Creators.

Everything you need to fix safe-zone collisions, normalize -14 LUFS audio, validate .SRT/.VTT subtitles, and batch-clean up to 10 videos at once.

1

1-Click Safe-Zone Auto-Reframe

Captions or bottom hooks colliding with the TikTok description drawer? Preview your 9:16 video elevated and scaled (`86%`) inside the 100% clear safe zone over an ambient blurred canvas.

2

-14 LUFS Audio & Peak Limiter

Prevent TikTok and Instagram Reels from ducking your voiceover. Measure integrated loudness in LUFS and preview real-time Web Audio `-14 LUFS` normalization with a `-1.0 dBFS` true-peak limiter.

3

Upload Compatibility & tkhd Rescue

Inspect MP4/MOV `tkhd` 3×3 orientation matrices for 90°/180°/270° sideways rotation bugs, verify progressive `moov` fast-start alignment, and reset container headers losslessly.

4

Batch Multi-Video Queue (Up to 10)

Drop up to 10 MP4 or MOV files at once to audit every video’s 0–100 Health Score in a unified queue and clean the entire batch with the £6.99 Creator 10-Pack (69p per video).

5

.SRT / .VTT Subtitle Safe-Zone Validator

Upload or paste `.SRT` and `.VTT` caption files to spot overlapping cues or lines over 42 characters, preview live subtitles inside the 9:16 simulator, and export a safe-positioned `.VTT` file.

6

TikTok Shop Anchor & Spark Ads Mode

Toggle the orange TikTok Shop product anchor card (`138px` bottom offset) in the simulator so product links never cover your subtitles, and verify 5-point Spark Ads eligibility.

COMMON QUESTIONS

Frequently Asked Questions

Straightforward answers about our video processing, audio checks, and privacy.

No. UploadCorrect uses in-browser lossless stream copying. We operate directly on container atom headers without transcoding or touching the underlying H.264 or HEVC frame bitstream (the mdat atom). Your output file retains 100% of its original resolution, clarity, and bitrate.

The Video Health Score is a deterministic 0–100 technical rating across 5 categories: Platform Compatibility (30 points), Video Integrity & Export (25 points), Audio Quality (15 points), Metadata & Privacy (15 points), and Visual Safe-Zone Readiness (15 points). It evaluates technical container properties against published platform specifications.

The simulator renders your video inside a realistic phone mockup with actual interface overlays for TikTok, Instagram Reels, and YouTube Shorts. It lets you test whether subtitles, logos, or faces are hidden behind platform action buttons before you upload.

No. No legitimate service can manipulate social media recommendation algorithms or guarantee virality. UploadCorrect ensures your video container is technically sound, strips editing software tags, aligns container atoms for instant streaming, and protects your privacy.

No. Both the free technical scan, audio inspection, safe-zone checks, and paid preparation run 100% locally in your web browser memory via HTML5 Web APIs. Your video pixels never travel across the internet to an external server, protecting your privacy completely.

No account or password is required. You can scan videos immediately for free. When you choose to prepare a video, payment is handled securely via Stripe, and credits can be restored at any time using your email address.

Use the 1-Click Safe-Zone Auto-Reframe and TikTok Shop Anchor toggles inside the 9:16 Simulator, or upload your .SRT / .VTT subtitle file to validate cue timing and export a safe-positioned WebVTT file (`line:70%`) where every subtitle sits above the caption drawer and TikTok Shop product anchor.

TikTok, Instagram Reels, and YouTube Shorts normalize audio toward -14 LUFS integrated loudness with a -1.0 dBFS true-peak ceiling. UploadCorrect measures your track's loudness and lets you preview -14 LUFS loudness normalization with a real-time Web Audio peak limiter in one click.

Yes. Drag and drop up to 10 MP4 or MOV files at once into the scanner to audit every video's 0–100 Health Score in a batch queue and clean all 10 videos with the £6.99 Creator 10-Pack (just 69p per video).
