YouTube recompresses every video you upload — this is unavoidable. But the quality of YouTube's output depends heavily on the quality of your input. If you upload a low-quality, over-compressed source file, YouTube's encoding will make it worse. Upload a high-quality source and YouTube's encoding will look great. Here's how to get your export right.

YouTube's Recommended Upload Specs (2025)

  • Container: MP4 (recommended), MOV, AVI, WebM also accepted
  • Video codec: H.264 (recommended for compatibility), H.265 or VP9 also accepted
  • Audio codec: AAC (recommended), MP3 also accepted
  • Resolution: Upload at the highest resolution available (4K if you have it, minimum 1080p)
  • Frame rate: Match your source — 24fps, 30fps, or 60fps
  • Bitrate: YouTube recommends 8 Mbps for 1080p/30fps, 12 Mbps for 1080p/60fps
  • Maximum file size: 256 GB
  • Maximum length: 12 hours

Exporting from VIDEO CUTTER for YouTube

VIDEO CUTTER's export options are straightforward. Here's what to choose:

Format

Choose MP4. While YouTube accepts WebM, MP4 is the standard and most widely supported. The MP4 export from VIDEO CUTTER uses H.264-compatible encoding wrapped in an MP4 container.

Quality

Choose High. This sets the output bitrate to 5 Mbps. For 1080p content, this is below YouTube's recommended 8 Mbps but well within the range that produces excellent results after YouTube's processing. YouTube's own encoding algorithms work best when given a high-quality source.

Why Higher Quality = Better YouTube Output

YouTube uses a two-pass encoding system. It generates multiple quality versions of your video (360p, 720p, 1080p, 4K if applicable) from your uploaded source. When your source file has more visual information — higher bitrate, sharper details — YouTube's encoder has more data to work with and produces better results at each quality tier.

This is why YouTubers say "upload the highest quality you can." A 1080p video uploaded at 15 Mbps will look better on YouTube than the same video uploaded at 3 Mbps, even though YouTube will re-encode both to roughly the same output bitrate.

💡 Upload in 1080p Minimum

YouTube's 720p streams are processed differently from 1080p. Videos uploaded at 1080p get better compression treatment on YouTube's end. If your source is 1080p, always export at 1080p — never downscale before uploading.

Aspect Ratio for YouTube

YouTube's player is 16:9. Upload videos in 16:9 aspect ratio for the best display. If your video is vertical (9:16 for Shorts) or square (1:1), YouTube will add letterboxing/pillarboxing to fill the 16:9 player frame for regular uploads.

For YouTube Shorts: Upload vertically at 9:16, under 60 seconds. YouTube will display these in the Shorts feed without letterboxing.

YouTube Shorts vs Regular Videos

  • Regular video: 16:9 landscape, any length up to 12 hours, export MP4 High quality
  • YouTube Shorts: 9:16 vertical, under 60 seconds, export MP4 High quality

Before You Upload

  • Trim your video tightly in VIDEO CUTTER — no dead air at the start or end
  • Export as MP4 at High quality
  • Check your audio levels are consistent throughout
  • Verify the aspect ratio matches your intended upload type
  • Upload as soon as possible after export — YouTube takes time to process higher resolution versions
