Video Specs & Bitrate Inspector (100% Local, No Upload)

Most platforms re-encode uploaded videos to optimize playback and bandwidth. You can't fully control platform compression — but you can control what you upload. If your source file is already heavily compressed (low bitrate) or uses unusual settings (e.g., variable frame rate), quality loss can be much more noticeable after re-encoding.

Creators frequently report that videos look crisp locally but become softer or pixelated after posting, even with "Upload HD" enabled — which is why checking your actual export specs before uploading matters.

• Container & codecs — MP4/MOV, H.264/HEVC, AAC/Opus
• Resolution & aspect ratio — 9:16 / 16:9 / 1:1 and unusual ratios
• Frame rate & frame rate mode — CFR vs VFR detection
• Bitrate — Reported (if available) + estimated average total bitrate (file size ÷ duration)
• Platform checklists:
  • YouTube recommended upload encoding settings (official)
  • TikTok In-Feed Ads baseline specs (official ads specs)

YouTube publishes recommended upload encoding settings such as MP4 container, H.264 video (progressive, High Profile), and AAC-LC audio at 48 kHz. YouTube also provides recommended video bitrates by resolution and frame rate (SDR and HDR). This tool compares your file against those recommendations so you can spot potential export issues early.

YouTube Recommended Bitrates (SDR)

• 1080p (24/25/30 fps): 8 Mbps
• 1080p (48/50/60 fps): 12 Mbps
• 1440p (24/25/30 fps): 16 Mbps
• 1440p (48/50/60 fps): 24 Mbps
• 4K (24/25/30 fps): 35–45 Mbps
• 4K (48/50/60 fps): 53–68 Mbps

TikTok's Ads Manager publishes In-Feed video specifications (for ads), including recommended 9:16 creatives, minimum vertical resolution (≥540×960), max file size (≤500MB), and a minimum bitrate threshold (≥516 kbps). While organic uploads may differ, these official specs are a useful baseline for compatibility checks.
