The ceiling is high. Something else stops you

Platform upload limits are measured in gigabytes and short clips are measured in megabytes. The limit is rarely what blocks a post.

01

Do file size limits ever matter for clips?

Almost never. A one minute vertical clip at sensible settings lands somewhere between 10 and 60 megabytes, while platform ceilings run into gigabytes. Size limits bite when uploading long source video, not when posting the clips that come out of it.

02

What actually gets an upload refused

Ceilings are measured in gigabytes and finished clips in megabytes, so the limit that stops people is almost always duration or shape rather than weight.

ReasonHow often it is the causeWhere it bites
Clip too long for the placementCommonPosting side
Wrong shape for the placementCommonPosting side, usually a bad crop rather than a refusal
Source over the plan allowanceCommonBefore the clips exist
Source longer than the plan allowsCommonBefore the clips exist
File genuinely over a platform ceilingVery rare for clipsAlmost never

03

When uploads fail for other reasons

Most failed uploads come from unstable connections, apps closed halfway through, or an unsupported file format rather than size. Uploading over a stable Wi-Fi network with the app kept open usually solves the problem. If an upload stalls repeatedly, restarting the app and trying again often works better than waiting.

Files exported with unusual settings, such as rare codecs or odd frame rates, can also be rejected. A standard format with common settings is the safest choice for every platform.

04

Handling large source files

Long recordings, especially at high resolution, can reach many gigabytes. Moving them around takes time, so plan uploads of source material for moments when you do not need the connection for anything else. Overnight uploads over a wired or strong Wi-Fi connection are the least frustrating.

If a source is far larger than needed, a copy with a lower bitrate at the same resolution can shrink it substantially while keeping the clips looking the same on a phone.

05

Duration limits matter more

Each platform sets a maximum length for short clips, and those limits change from time to time. A clip that is a few seconds too long may be posted as a regular video instead of a short, or rejected entirely. Check the current limit before planning clip lengths.

Shape can also change how a clip is treated. A horizontal or square video may not be placed in the short-video feed at all, even if it is short enough.

06

Keeping export settings consistent

Once you find settings that upload smoothly and look good on every platform, save them as a preset in your editing tool. Using the same preset every time avoids surprises and makes troubleshooting simple when something does go wrong.

Update the preset only when a platform changes its recommendations, and note the date you changed it.

07

The limit that actually applies to you

  • Check length before size. Duration limits stop more posts than file size does.
  • Watch size on the way in, not out. The constraint is on your source material rather than your clips.
  • Use a link for large sources. It removes the transfer question entirely.

Check your source against your plan and send it.

Questions people ask

What are the limits here?
The free video takes two gigabytes, Lite 10 four, Lite 30 eight, and Lite 50 twelve.
Why is my source file so much bigger than my clips?
Because a source is long and recorded generously, while a clip is short and produced for delivery. An order of magnitude between them is normal.
Does a bigger upload give better clips?
Only up to the point where the picture is clean. Past that it adds transfer time and nothing else.
What stops a post more often than size?
Duration and shape. A clip that is too long or the wrong proportions gets refused where a large one would not.
Can I reduce a source without hurting the clips?
Usually yes, by exporting at a lower bitrate. Most recordings carry far more data than the picture needs.
