Check frame timing when movement looks different after an export.
Video Resolution Checker
Check your video’s width, height, aspect ratio and orientation before you edit or share it. Choose a local file to see its dimensions, with rotation taken into account.

A clearer picture of your video's dimensions
A file called final-4k.mp4 may have been exported at 1080p. A portrait clip can carry a rotation setting that makes its stored dimensions look horizontal. The Video Resolution Checker helps you check the file itself, so you can work from its dimensions rather than its name or the size of a player window.
Start with the width and height, then read the aspect ratio and orientation alongside them. Together, those measurements tell you whether an export has the shape you intended. They also help you spot a smaller copy before you use it in a larger project. Checking a file does not resize it or change its picture.

How to use the Video Resolution Checker
Choose the file you actually plan to use
Select a video from your device or drop it into the tool. If you have several exports, check the final delivered copy. An editor's project settings describe the timeline; they do not prove that every export was saved at that size.
Read width and height together
Look for a pair such as 1920 × 1080. The first number is width and the second is height. Check the orientation and aspect ratio too, especially when a phone recording should appear upright or a square edit is intended for a different layout.
Compare the result with your intended export
If the dimensions are wrong, return to your editor and review its export settings. Check the new file again after exporting. Keep the original recording separately, particularly if a smaller version has already been cropped, compressed or shared through another app.
What the Video Resolution Checker results mean
Resolution: the size of the frame
Resolution describes the frame's dimensions. A 1920 × 1080 frame contains about 2.07 million pixels; a 3840 × 2160 frame contains about 8.29 million. These numbers describe space for image detail. They do not tell you how much useful detail the camera captured or how well the video was compressed.
Aspect ratio: the shape of the frame
Aspect ratio compares width with height. Both 1280 × 720 and 1920 × 1080 have a 16:9 shape. A 1080 × 1920 clip has a 9:16 shape. The proportions matter when you place footage in a new canvas: preserving them avoids stretching faces, products and text.
Orientation: how the picture is presented
Landscape is wider than it is tall, portrait is taller than it is wide, and square has equal sides. Orientation is useful when checking several exports for different placements. It describes the complete frame, including any black bars already baked into the video.
Common video dimensions at a glance
Use these familiar sizes as reference points. Exact dimensions remain more useful than a short label when a video is cropped, unusually wide or intended for a custom display.
| Common name | Width × height | Shape |
|---|---|---|
| HD | 1280 × 720 | 16:9 landscape |
| Full HD | 1920 × 1080 | 16:9 landscape |
| QHD | 2560 × 1440 | 16:9 landscape |
| 4K UHD | 3840 × 2160 | 16:9 landscape |
| Portrait Full HD | 1080 × 1920 | 9:16 portrait |
| Square | 1080 × 1080 | 1:1 square |
YouTube's resolution reference lists the landscape dimensions above. Other shapes can be valid too. A 1920 × 800 film export is wider than 16:9; it should not be stretched to 1920 × 1080 merely to match a familiar label.
Why a phone video can have two sets of dimensions
Some files store a landscape frame and include an instruction to rotate it for playback. A player may therefore present a 1920 × 1080 stored frame as a 1080 × 1920 portrait picture. Both numbers can describe the same file, but they refer to different stages of displaying it.
Older or specialist footage can also use non-square pixels. Its stored width and height may differ from the shape viewers see after display adjustments. If two apps report different dimensions, look for rotation and display information before assuming that one app resized the video. Use the displayed picture when deciding how the clip should fit your layout.
The main result uses display dimensions, with the stored dimensions and rotation shown separately. Read them together when a file behaves differently across editing apps. A custom size remains a custom size; it is not forced into an HD or 4K label.
Check your export before the next step
Before handing footage to an editor
Use the Video Resolution Checker to confirm which copy you received. A small preview and a camera original can have nearly identical filenames. Send the measured dimensions with your handoff so the editor can choose a suitable timeline and identify clips that will need extra care when enlarged.
Before repurposing a horizontal video
Changing a landscape clip into a tall canvas involves a composition decision. You can crop, add space around it, or arrange it with other elements. Check the source dimensions first; the available width and height help you judge how much of the subject can remain visible.
After a cleanup or re-export
Check both the original and the finished copy if dimensions must stay consistent. A matching resolution confirms the frame size, but still review the picture and motion. This is especially useful when cleaning overlays or preparing footage for another editing pass.
A 4K label cannot explain a blurry picture
The Video Resolution Checker measures dimensions; it does not award a sharpness score. A soft recording exported onto a 4K canvas is still soft. Compression can remove fine texture, camera movement can blur a frame, and an enlarged source can have more pixels without recovering the original detail.
If your dimensions look correct but the result looks poor, compare it with the original at the same viewing size. Check faces, small text and moving areas. Avoid judging only from a tiny preview, where artifacts are harder to see. Resolution is one useful check in that review, alongside motion, compression and the condition of the source.
Check a local file, keep the original
The Video Resolution Checker accepts MP4, MOV, WebM and MKV files up to 2 GB and inspects the main video track. Your selected file is read on your device and is not uploaded for this check. There is no conversion step and no new video to download.
A supported extension does not guarantee that every file can be read. Unfinished recordings, damaged transfers or unusual container features can cause an error. When that happens, keep the original, check that it plays correctly, and try a complete copy.
Video Resolution Checker questions
01Is the Video Resolution Checker free?
Yes. Checking video dimensions does not require an account or processing credits. Choose a local file to read its details. Paid cleanup features elsewhere on RemoveText.video are separate from this checker.
02Does this change or compress my video?
No. The Video Resolution Checker reads information about the selected file. It does not resize, crop, re-encode or overwrite it. To change dimensions, use your editor's export settings and check the newly exported copy afterward.
03Why does a vertical 1080p clip show 1080 × 1920?
Its width is 1080 pixels and its height is 1920 pixels, giving it a 9:16 portrait shape. The familiar landscape arrangement is 1920 × 1080. Always keep both numbers and their order when describing a file.
04Can the Video Resolution Checker prove that footage is native 4K?
No. It can identify 4K-sized dimensions, but those dimensions do not reveal whether the footage was originally captured at that size. A smaller source can be enlarged before export. Confirm the recording settings and inspect the source if that distinction matters.
05Why does my video have the right dimensions but black bars?
Bars can be part of the encoded picture. A 1920 × 1080 frame might contain a narrower or shorter image with empty space around it. The checker measures the whole frame; it does not detect or remove those built-in borders.
06What should I do if the file cannot be read?
Check that the file opens normally and that the transfer finished. A familiar extension does not guarantee a supported container or an intact file. Try the original copy or inspect it in a desktop media tool; renaming the extension will not repair it.
