Free media metadata viewer
Inspect video and audio properties in your browser
Check MP4, WebM, MKV, MOV, MP3 and M4A files before editing or sharing. See the container, codec, resolution, frame rate, sample rate, channels and bitrate.
See important details
Find resolution, FPS, codec, sample rate, channels, bitrate and duration in one report.
Troubleshoot playback
Check why a video will not play or whether a download contains both video and audio.
Private local analysis
The file is read in your browser and is not sent to a FlowPick server.
When should you use a media information analyzer?
A file extension does not tell the whole story. Two MP4 files can use different codecs, resolutions or bitrates, which affects playback and editing. Use this free media metadata viewer to inspect a downloaded video, verify a converted file, check an audio track, or prepare a file for an editor. Export the local report as JSON when needed.
Check before editing
Confirm resolution, frame rate and codec before importing MP4, WebM or MOV footage into an editor.
Find missing tracks
See every detected track and check whether a downloaded file contains the expected audio and video.
Compare media quality
Use bitrate, duration, dimensions and codec details to understand different file sizes or playback results.
How it works
Analyze a media file in three steps
No account or command line is needed.
Choose a file
Drop a video or audio file into the analyzer.
Read the report
FlowPick reads container and track metadata in your browser.
Export the details
Copy the JSON report when you need to share technical information.
What the file is really telling you
The extension is only the label on the box. These checks explain the details that usually cause playback, editing, or upload surprises.
MP4 is a container, not a codec
Two MP4 files can carry different video and audio codecs. When one device plays a file and another does not, compare the codec and parameters instead of looking only at .mp4.
Why a video has no sound
A video-only file may be intentional, or audio may have been left behind during a separate-stream download. This report makes the missing audio visible before editing or sharing.
VFR and CFR are not the same
Variable frame rate can look fine in a player but cause timeline drift or sync problems in an editor. Check the frame rate before matching a project or cutting long recordings.
M4S and TS files need context
M4S fragments and MPEG-TS segments are often pieces of a streaming presentation rather than a finished video. Track details help distinguish a segment from a ready-to-play file.
Media information analyzer FAQ
Which files can this analyzer inspect?
It focuses on MP4, WebM, MOV, MKV, MP3, M4A, AAC, WAV, OGG and FLAC files.
Are my files uploaded?
No. Analysis runs locally in your browser and the file is not sent to a processing server.
Can it repair or convert a video?
No. It reports media information only. Use related conversion or downloader tools to create a new file.
Why is some information unavailable?
Some containers do not store every field. The analyzer only displays information it can read reliably.
