Review streams, metadata, timeline continuity, truncation signals, tag sizes, and a cancellable SHA-256 fingerprint.
Review precisely
Seek, change speed, request adjacent frames, set an A–B loop, and pin the player above other windows.
Control audio and subtitles
Choose available tracks or add a local external subtitle while the original media stays untouched.
Leave a portable record
Add timestamped markers, save a review session, and export diagnostics as JSON or readable Markdown.
Keep work on your PC
No account, ads, telemetry, cloud processing, automatic uploads, or bundled codec-pack setup.
Clear scope. Honest results.
Inspect even when a stream cannot play.
FLV and F4V are containers, so playback still depends on the codecs inside each file. When a stream is unsupported or damaged, FLV Video Player Pro keeps its metadata, findings, markers, and export tools available instead of claiming a repair it did not perform.

Coming to Microsoft StoreQuestions, answered
Before you open the archive
Does the app upload my videos?
No. The desktop app initiates no uploads, analytics, advertising, cloud processing, or update-check requests.
Will every FLV file play?
Not necessarily. FLV is a container and older files may contain unsupported or damaged streams. Inspection can still remain available.
Does it change or repair files?
No. Source media is opened for local review. Snapshots, sessions, and reports are written only when you choose a destination.
Where can I get help?
The support guide covers playback, subtitles, damaged files, diagnostics, and the information to include with a support request.
