Video to Notes
Video specs → platform verdict
Drop a file to read its resolution, aspect ratio, length, size, bitrate and codec, then get a field-by-field verdict against nine upload targets — in your browser, nothing uploaded.
Most checkers stop at width and height. This one reads the container, video codec and profile, pixel format, frame rate, real bitrate and the audio track too, then tells you exactly which field breaks which platform's published spec — and links to the tool that fixes it. Your file is read on your own device; nothing is uploaded and nothing is re-encoded.
How it works
01
Drag in a file — MP4, MOV, WebM, MKV, or anything else your browser can decode. Files up to 8 GB are fine: only the header region is read, so a large export costs no more memory than a small one. No file handy? Type the numbers in by hand instead.
02
Resolution, aspect ratio, orientation, duration, file size and overall bitrate appear immediately. The in-browser engine then fills in container, video codec and profile, pixel format, frame rate and the audio track. Anything it cannot read stays blank rather than being guessed.
03
Nine platforms are checked field by field, worst first, with your value and the published limit side by side in the same units. Each problem links to the tool on video-to-notes.com that fixes it — the trimmer, the compressor, or the converter.
Reference
The short answer for vertical video. The TikTok aspect ratio, the YouTube Shorts aspect ratio and the Instagram Reels aspect ratio are the same shape: 9:16 vertical, at 1080 × 1920 — the size and dimensions all three platforms recommend. TikTok and Instagram accept a wider file and then crop or letterbox it; YouTube Shorts treats anything wider than 1:1 as a normal video rather than a Short.
The short answer for length. A YouTube Short and an Instagram Reel both stop at 3 minutes, a standard X post at 2 minutes 20 seconds, LinkedIn's feed at 15 minutes, and TikTok's web uploader at 60 minutes.
The short answer for landscape video. YouTube recommends 16:9 and accepts 240p through 8K; Instagram's feed displays between 4:5 and 1.91:1; LinkedIn rejects anything outside 1:2.4 to 2.4:1 and X anything outside 1:3 to 3:1.
Every limit below is what the platform itself publishes, encoded by hand and last verified on 2026-08-09. Platforms change these without notice, and a “hard limit” is only marked as one where the platform documents an actual reject — so meeting everything here is not a guarantee that your upload will be accepted. The checker above runs this exact table against your file.

Plain English
Everything the checker reports is video metadata — the properties an editor writes into the file when it exports, and the properties an upload form reads back. Here is what each one means, and which of them a platform actually cares about.
Resolution — how many pixels the picture has, written width × height. 1920 × 1080 is “1080p”; 3840 × 2160 is 4K. More pixels means more detail and a bigger file.
Aspect ratio — the shape those pixels make. 1920 × 1080 is 16:9 (landscape); 1080 × 1920 is 9:16 (vertical). This is the field that most often decides whether a video is shown full screen, cropped, or padded with bars.
Orientation — landscape, portrait, or square. A phone clip is often stored landscape with a rotation flag and displays portrait, so the shape that matters is the one you see, which is what this page reports.
Duration — how long the video runs. Several platforms treat this as a hard eligibility rule rather than a suggestion: over the limit and the upload becomes a different kind of post, or is refused.
Bitrate — how much data each second of video uses, in kbps or Mbps. This, far more than resolution, is what drives file size and how clean the picture looks. Two 1080p files can differ ten-fold in size because their bitrates differ.
Frame rate — how many frames per second. 24, 25, 30 and 60 are the common ones; 29.97 and 23.976 are the broadcast oddities you will see on exports from many editors.
Container vs. codec — the container (MP4, MOV, WebM, MKV) is the box; the codec (H.264, HEVC, VP9, AV1) is how the picture inside it is compressed. A platform can accept your container and still refuse your codec, which is why they are checked separately.
Profile and pixel format — the specific flavour of the codec (High, Main) and how colour is stored (yuv420p is the safe, universally playable choice). These rarely block an upload, but they are the first place to look when a file plays on your machine and nowhere else.
What this tool does and doesn't do
Nothing is uploaded. Your file is read in the page. There is no account, no server-side processing, and no API call while a check runs — the only network requests are this page's own static files and the video engine, which is downloaded once and cached.
We diagnose; we don't edit. This page never modifies, re-encodes, resizes or re-wraps your video. When a check fails it links to the sibling tool that fixes that exact problem, and those run in your browser too.
Published guidance, not a promise. Every limit is taken from the platform's own documentation, is dated, and links to its source. Platforms revise these without notice, and each one applies rules no file inspector can see. A pass is a match against the spec we encoded, not a guarantee of acceptance.
Unknown beats wrong. When a field cannot be read, it is shown as unknown and every check that depends on it reports unknown too. Nothing is filled in with a plausible-looking number.
Fix what the checker found
This page diagnoses; these change the file. Each one runs in your browser the same way the checker does, and each is the tool the matrix above links to when that particular field fails. There are more at all our browser video tools.
Too long for Shorts, Reels, or X — cut it to length without re-encoding.
Over a file-size or bitrate limit — make it smaller and keep it watchable.
Wrong container or codec — re-encode between MP4 and WebM.
Audio you need gone — strip the track and keep the picture.
Pull the audio track out as MP3, M4A, or WAV.
Grab a still for a thumbnail as a JPG or PNG.
Turn a short clip into a shareable animated GIF.
Transcribe the video and get the full text of what was said.
Need more than the specs?
If you want the words, not the numbers, Video to Notes transcribes a video and writes a summary, key points, and a timeline you can download. For YouTube links and longer videos, the Chrome extension does it right in your browser.
Or get the Video to Notes Chrome extension to turn a YouTube video into notes without leaving the tab.
FAQ
Drop a video file onto the box at the top of this page, or choose one. The width, height, aspect ratio, orientation, duration, file size and overall bitrate appear straight away, read from the file on your own device. A moment later the in-browser engine fills in the video codec, profile, pixel format, frame rate and audio details.
All three are built around 9:16 vertical, and 1080 by 1920 is the resolution each of them recommends. TikTok and Instagram accept a different shape and then letterbox or crop it in the feed, so the checker reports that as a warning. YouTube Shorts treats shape as an eligibility rule: anything wider than 1:1 still uploads but is not classified as a Short, so the checker reports that as a failure. The reference table on this page gives the published figure and its source for all nine platforms.
3 minutes for a YouTube Short, 3 minutes for an Instagram Reel, and 2 minutes 20 seconds for a video posted to X from a standard account. TikTok's web uploader goes up to 60 minutes and LinkedIn's feed up to 15. Those are the figures each platform published on the verification date shown above the reference table, and every row links to the documentation it was encoded from.
No. The file never leaves your device. It is read in the page, and only the header region is read at that. There is no account, no upload and no API call during a check - the only network requests are this page's own static files and the video engine it loads once.
No. The limits here are what each platform publishes, encoded by hand on a stated date and shown with a link to the source. Platforms change them without notice, and every platform also applies rules this tool cannot see, such as content and copyright review. A pass means your file matches the published spec we encoded, not that the upload will succeed.
Because the platforms behave differently, and pretending otherwise would make the whole table useless. TikTok and Instagram accept a landscape video and then letterbox or crop it in the feed, so a mismatch is a warning about how it will look. YouTube Shorts and Reels use shape and length as eligibility rules, so a video that is too wide or too long is not published in that format at all. Only a documented hard reject is marked as a failure.
Yes, up to a defensive 8 GB ceiling. Most in-browser tools read the whole file into memory and fall over on a large export. This one mounts the file and reads only the header region it needs, so a multi-gigabyte source costs no more memory than a small one.
The fields it could not read show a dash and a note saying so, and every check that depends on them reports as unknown rather than as a pass. Resolution, aspect ratio, duration, file size and overall bitrate come from a separate, simpler read, so they stay accurate even when the deeper read fails.
Resolution is how many pixels the picture has, written as width by height, for example 1920 by 1080. Aspect ratio is the shape those pixels make, 1920 by 1080 being 16:9. Bitrate is how much data each second of video uses, which is what actually drives file size and how clean the picture looks. Two files can share a resolution and an aspect ratio and still differ enormously in size, because their bitrates differ.
No. This page diagnoses; it does not change your file. Every failing or warning check links to the tool on video-to-notes.com that fixes that specific problem - the trimmer for length, the compressor for size and bitrate, the converter for container and codec - and those tools also run entirely in your browser.
