What the app measures, before you upload anything.
The Compare Videos tool by Metadata2Go helps you detect differences between two videos by analyzing their quality frame by frame. It uses a machine learning-based video quality algorithm designed to closely predict how viewers perceive video quality.

VMAF stands for Video Multimethod Assessment Fusion. The report shows up to 12 metrics in all, VMAF plus the ADM, motion, and VIF measures behind it, and each one is pooled 4 ways: harmonic mean, mean, max, and min.
Numbers replace opinions. Two people can disagree about which video looks better; the metrics do not.
This app analyses the two videos instead of playing them next to each other. There is no video player and no scrub bar. What comes back is the evidence: a table that puts both files in adjacent columns, and a gallery of difference images.
The File Details table lines up 7 properties for each video, so a mismatch in dimensions, duration, or codec is visible in one glance rather than after two rounds of checking file info by hand.
The Frame Comparison gallery shows where the two videos stop matching. Each image marks the difference at that point in the timeline, which is what a quality drop, a re-encode artefact, or an edited shot looks like on screen.
Everything the comparison finds lands in one report: the file details, the quality metrics, and the frame differences, in that order. Export PDF turns the whole thing into a single file with a page footer that names where it came from.
That matters when the comparison is evidence for somebody else. A colleague reviewing an encode, a client signing off a delivery, or a case file six months from now all need a document rather than a browser tab.
The report stays with the comparison in your workspace, so reloading the page does not throw the result away.
The comparison runs on our servers and the result opens in your browser. There is no binary to download, no package to compile, and no command line to learn, which is what most of the alternatives ask for before they show you anything.
Each of the 2 videos can come from wherever it already is: your device, a direct link, Google Drive, Dropbox, or OneDrive. A file already open in your workspace can be dropped into either slot with one click.
Comparing videos is free and needs no account. Each video can be up to 75 MB, and a paid plan raises that to 8 GB.
Accepted formats: MP4, WebM, OGG, MOV, MKV, AVI, FLV, WMV, and M4V.
Three sections and an export. This is everything the app hands back after it compares the 2 videos.
| Report section | What it shows | Where it comes from |
|---|---|---|
| Alaye Fáìlì | 7 properties, both videos | The 2 uploaded files |
| Quality Metrics | Up to 12 metrics, 4 figures each | The frame analysis |
| Frame Comparison | Difference images, frame by frame | The frame analysis |
| PDF export | The whole report in one file | Built in your browser |
The 7 file properties are name, size, dimensions, duration, file type, video codec, and audio codec. Every metric is pooled 4 ways: harmonic mean, mean, max, and min, to 4 decimal places. A metric the analysis does not return is left out of the table rather than shown as zero.

Before a delivery goes out, compare the export against the graded master. The metrics say whether the render held up, and the frame images say exactly where it did not.
A smaller file always costs something. Compare the re-encoded video with the source and you can see what the saving cost, instead of guessing at a bitrate.
Two copies of the same recording should be identical. When they are not, the report shows which frames differ and hands you a PDF you can attach to the case.
The footage you compare can be unreleased, confidential, or evidence. Here is exactly how it is handled.
Nobody reads, watches, or copies the videos you upload. The comparison is fully automated. The download link is generated at random and cannot be guessed.
Your videos are not used to train AI models. You keep the copyright and the ownership of both files you upload and of the comparison report you get back.
The servers that do the work are located exclusively in Europe, under a data processing agreement you can download. Only what the comparison needs is processed.
Upload the two videos you want to compare.
Add the first video. This is the reference the second one is measured against.
Add the second video and start the comparison. Both files are analysed frame by frame.
Open the report to read the metrics and the frame differences, then export it as a PDF.
Upload the first video, which is the reference, then add the second one and start the comparison. The app analyses both files frame by frame and returns a report with the file details, the quality metrics, and the frames where the two videos differ.
Read the VMAF row in the Quality Metrics table. VMAF is built to predict how a viewer would rate the picture, so a higher score means the video looks closer to the reference. The other 11 metrics say how similar the two files are on detail, motion, and contrast.
This one runs in the browser, so there is nothing to install and no command line to learn. Most alternatives are desktop programs that have to be downloaded or compiled first. Upload 2 videos here and the comparison report opens in the same tab.
MP4, WebM, OGG, MOV, MKV, AVI, FLV, WMV, and M4V. The 2 videos do not have to share a format, so an MP4 can be compared against a MOV of the same footage.
VMAF stands for Video Multimethod Assessment Fusion. It is a machine learning-based metric that fuses several image measures into one number designed to track how people actually judge video quality. The report shows it alongside the ADM, motion, and VIF measures it is built from.
No. A comparison takes exactly 2 videos, a reference and the one you check against it. To compare a third file, run a second comparison against the same reference.
Yes. Comparing videos is free and no account is needed. Each video can be up to 75 MB on the free tier, and a paid plan raises that to 8 GB.
Yes. Nobody reads, watches, or copies your files, because the comparison is fully automated. Your videos are never used to train AI models, the servers are located exclusively in Europe, and you keep the copyright and the ownership of everything you upload.
Upload here and both videos open in the workspace, where the wizard walks through the 2 files and the report is built.
The first video is the reference. The second is the one measured against it.
