饾晱 video spec checker
Drop a video. Your browser reads its size, length and dimensions, and the checker compares them with the limits 饾晱's help page gives for uploading on the web, with or without 饾晱 Premium. The file stays on your device.
Updated
The checks show here: file size, length, dimensions, aspect ratio and bitrate.
Everything runs in your browser. The video is read on your device and never uploaded to Crux or anyone else, and nothing is saved.
How it works
饾晱's help page on videos, read on 19 October 2026, says an account without a subscription can upload videos up to 140 seconds long and 512 MB, and 饾晱 Premium accounts videos shorter than 4 hours and up to 16 GB, at 1080p up to 2 hours and 720p above that. For uploads on the web it gives a resolution from 32 x 32 to 1920 x 1200 (1200 x 1900 in portrait), an aspect ratio from 1:2.39 to 2.39:1, at most 40 frames a second and at most 25 Mbps. This checker tests each limit a browser can measure; it cannot read the frame rate.
Questions
How long can a video on 饾晱 be?
140 seconds without a subscription, and just under 4 hours with 饾晱 Premium, according to 饾晱's help page on 19 October 2026. Above 2 hours, 饾晱 Premium videos play at 720p.
Why does it flag my 1080 x 1920 portrait video?
It does not flag it, but it notes it. 饾晱's help page writes the portrait maximum as 1200 x 1900, so 1920 pixels is taller than written. 饾晱 may still accept it; if it refuses, export at 1068 x 1900, which keeps 9:16.
Is my video uploaded anywhere?
No. Your browser reads the file's details on your device, and the page sends nothing anywhere. You can check it with your network turned off.
Why does it say it could not read my video?
Browsers only read the details of formats they can play. The checker still checks the file size; for the rest, export as MP4 with H.264, which every major browser reads.
From one post to every push
Crux (cruxpost.com) watches the GitHub repos you choose. Each push, merged pull request or release becomes three drafts in your voice, checked the way this site鈥檚 tools check a post, and your coding agent can add why a change matters through the Crux plugin for Claude Code and Codex. Crux reads commit messages, pull request and release text and the names of changed files, never a diff. Post on X copies the draft you like and opens X with it, for you to post; on Autopilot, Crux posts only what you schedule. It reads each post at 1 hour, 24 hours and 7 days, and learns which kinds of post work for your account only once a pattern beats chance.
