What should I check before uploading a video to YouTube?
Check the exported file, not the timeline: an MP4 file, H.264 video, AAC or Opus sound at 48 kHz, the frame rate you recorded, about 8 Mbps at 1080p for 24 to 30 fps footage (12 Mbps for 60), a 16:9 frame with no added bars and Fast Start on. Verify the account if the video runs past 15 minutes, then check loudness, thumbnail, captions and chapters.
The checklist at a glance
Most upload problems are decided in the export window, long before you open YouTube Studio. Work through these in order:
- Check the account can take the length.
- Match the export settings to YouTube’s recommendations.
- Keep the frame rate you recorded.
- Check the shape: 16:9, or a Short on purpose.
- Run the exported file through an upload checker.
- Check the loudness and the gaps.
- Get the thumbnail, captions and chapters ready.
- Upload as private first and watch it back.

The last thing I do before handing over any video is check the export, from Rex & Alexa’s Roblox videos to Swaylemc’s feature-length Minecraft movies. The two free tools in this checklist are the checks I use.
Step 1: Check the account can take the length
By default, YouTube lets you upload videos up to 15 minutes long. Longer uploads need a verified account: the YouTube app sends a code by text message or an automated voice call. The maximum upload is 256 GB or 12 hours per file, whichever is less. Do this on a normal day, not when a 25 minute video is waiting to go up.
Step 2: Match the export settings to YouTube’s recommendations
YouTube Help’s recommended upload encoding settings, read October 19, 2026:
- Container: MP4, no edit lists, and the moov atom placed at the start of the file (what export windows call Fast Start).
- Audio: AAC-LC or Opus at 48 kHz; 384 kbps for stereo (128 kbps mono, 512 kbps for 5.1).
- Video: H.264, progressive, High Profile, 2 consecutive B-frames, a closed GOP of half the frame rate, CABAC, variable bitrate and 4:2:0 chroma. YouTube says no bitrate limit is required.
- Color: BT.709 for SDR uploads.
And the recommended video bitrates for SDR uploads:
| Resolution | 24, 25 or 30 fps | 48, 50 or 60 fps | Frame size (16:9) |
|---|---|---|---|
| 2160p (4K) | 35 to 45 Mbps | 53 to 68 Mbps | 3840 x 2160 |
| 1440p | 16 Mbps | 24 Mbps | 2560 x 1440 |
| 1080p | 8 Mbps | 12 Mbps | 1920 x 1080 |
| 720p | 5 Mbps | 7.5 Mbps | 1280 x 720 |
The free YouTube Export Settings Calculator turns this into settings you can type into Premiere Pro, DaVinci Resolve, Final Cut Pro or CapCut. Pick the resolution, the frame rate you recorded, SDR or HDR and the audio channels, add the length and your upload speed, and it gives the bitrate, the file size and the upload time. A 10 minute 1080p export at 30 fps comes to about 630 MB at YouTube’s recommended bitrate. If you are not sure whether your footage is HDR, it is SDR.
Step 3: Keep the frame rate you recorded
YouTube asks for content to be encoded and uploaded at the frame rate it was recorded at. A 60 fps gameplay capture stays 60 fps and gets the 60 fps bitrate. The trouble usually starts earlier, in the timeline: put 60 fps footage in a 30 fps sequence (or 30 in 60) and motion stutters, whatever the export says. Check the sequence settings before you export, not after. Interlaced footage should be deinterlaced first; YouTube’s example is 1080i60 to 1080p30.
If you are recording gameplay for someone else to edit, the settings at the start of the chain matter just as much: best OBS settings to record gameplay for your editor.
Step 4: Check the shape: 16:9, or a Short on purpose
16:9 is the standard on a computer, and YouTube’s player adapts to other shapes on its own. YouTube Help asks you not to add padding or black bars into the video file, because they get in the way of that resizing.
Shape also decides the feed: since October 15, 2024, a square or vertical upload that runs three minutes or less is treated as a Short. That is what you want for a Short, and a nasty surprise if an old vertical preset turns a two minute main video into one.
Step 5: Run the exported file through an upload checker
Before you upload, drop the exact file into the free Video Upload Checker. For MP4 and MOV it reads the codec, exact frame rate, audio track and Fast Start straight from the file header, then plays a couple of silent seconds to measure the rest, and compares the file with YouTube’s limits and recommendations. Nothing is uploaded; any file size works.
Each line of the report gets a color. Green is fine. Yellow flags a difference from YouTube’s advice or a change in how the upload is handled, such as becoming a Short or needing a verified account. Red is past a hard limit. Grey means your browser couldn’t read that detail, and the tool says so instead of guessing. Copy the report if someone else exported the file. Fix anything red or yellow in the export and run it again.
Step 6: Check the loudness and the gaps
Picture problems get noticed in the edit. Audio problems often don’t until viewers mention them. Drop the export into the free YouTube Loudness Check, which measures integrated loudness (LUFS), true peak and every silence longer than 1.5 seconds, in your browser. For context, the 50 big-channel videos in my loudness study had a median of −16.3 LUFS, and when I played the loudest ones back, YouTube had lowered them to −14. A hotter mix gains nothing. The method is in how loud YouTube videos are.
The silence list matters as much as the loudness number, because an accidental gap after a cut sounds like an error, and the silence detector finds the pauses inside the edit.
Step 7: Get the thumbnail, captions and chapters ready
- Thumbnail. YouTube Help lists 3840 x 2160 pixels as the resolution for video thumbnails, a minimum width of 640 pixels, a 16:9 shape, and JPG or PNG files, up to 50 MB from a computer (2 MB from a phone). The free thumbnail preview mocks it up next to your title in each place it will appear, phone included.
- Captions. An .srt file must be plain UTF-8 and only basic SRT is supported, with no style markup. Upload it under Subtitles in YouTube Studio.
- Chapters. Timestamps in the description, starting at 00:00, three or more in ascending order, with every chapter lasting 10 seconds or more. On a long video they let a viewer jump back to a part they want to rewatch.
Step 8: Upload as private first and watch it back
Upload as private or unlisted, then watch the first minute, a stretch in the middle and the last minute on a phone and on a computer. You are looking for the things no checker sees: a missing sound effect, a typo in a title card, a black frame at a cut, captions that drift. When it looks right, publish or schedule it.
What I check before I deliver a video
My last check is always on the exported file, never the timeline, because the export preset controls nearly everything above. A preset carried over from an earlier project can quietly drop a 60 fps gameplay video to 30, or flip a long-form video to vertical. Of everything on this list, frame rate is what goes wrong most often on the client videos I export, so the sequence has to match the recording before anything is exported, and 60 fps gameplay goes out at 60 with the 60 fps bitrate.
For 1080p I never export under YouTube’s 8 Mbps: every upload is re-encoded, and a file that starts thin only loses more detail. Length is the other one I check early: Swaylemc’s Minecraft full movies, which I edit, last anywhere from about an hour to nearly four, which means a verified account well before upload day. On those I add YouTube chapters at each act and keep one loudness level from start to end. Fast Start goes by different names: “Web Optimized” in HandBrake, “Network Optimization” in DaVinci Resolve, -movflags +faststart in ffmpeg.
Common upload mistakes
- Checking the timeline instead of the file that will actually be uploaded.
- A frame rate mismatch between the recording, the sequence and the export.
- Black bars rendered into the video to fake a 16:9 frame.
- A low bitrate to save upload time, which YouTube’s own re-encode then makes worse.
- An unverified account and a video over 15 minutes on upload day.
- A mix pushed louder than −14 LUFS, which YouTube turns down anyway.
Before you upload: FAQ
What export settings does YouTube recommend?
YouTube Help recommends an MP4 file with the moov atom at the front (Fast Start), H.264 video in High Profile with variable bitrate and 4:2:0 chroma, and AAC-LC or Opus audio at 48 kHz. Keep the recorded frame rate. At 1080p, aim for about 8 Mbps for 24 to 30 fps and 12 Mbps for 48 to 60 fps.
What bitrate should I export 1080p at for YouTube?
For SDR video, YouTube suggests roughly 8 Mbps when the frame rate is 24, 25 or 30, and 12 Mbps when it is 48, 50 or 60. YouTube calls these recommendations, not limits, and says no bitrate limit is required. Going a little higher only makes the file bigger and the upload slower.
Why can’t I upload a video longer than 15 minutes?
Because the account is not verified yet. By default YouTube allows uploads up to 15 minutes. Verify the account with a code sent by text message or an automated voice call, and the limit becomes 256 GB or 12 hours per file, whichever is less.
Should I export at 30 fps or 60 fps for YouTube?
At the frame rate you recorded. YouTube Help asks for videos to be encoded and uploaded at their recorded frame rate, so 60 fps gameplay stays at 60 and 24 or 30 fps footage stays where it is. Changing it in the timeline is what causes stutter.
What is Fast Start and do I need it?
Fast Start puts the moov atom, the index of the file, at the front of an MP4. YouTube lists it in its recommended upload settings. It is one checkbox in most export windows, often called Fast Start, Web Optimized or Network Optimization.
How do I add chapters to a YouTube video?
List timestamps and titles in the description. Per YouTube Help, the list starts at 00:00, has three or more timestamps in ascending order, and no chapter is shorter than 10 seconds.
