Know what you are working with.
Check the duration, file size, and video dimensions before moving on to editing or delivery. The workspace reads what your browser can identify.

THE WORKFLOW
See the details.
Keep the bigger picture.
You do not need a complicated dashboard to ask better questions about a media file. Start with a few useful checks.
Preview in context.
Use the native player to check playback, seek through a file, and listen to the audio. Support depends on the codecs available in your browser.
Try a fileKeep files on your device.
The inspector uses a local browser object URL. Your selected media is not uploaded to a server, and no account is needed.

FIELD NOTES
Good playback starts
with good questions.
A few practical ideas to take into your next project.
The container is
only the beginning.
MP4 and WebM describe containers. The video and audio codecs inside them help determine where a file can play.
Read the note
Two files with the same extension can use different codecs. If a file does not preview, try a player that supports its encoding before concluding that the file is damaged.
For publishing, test your actual export in the browsers and devices your audience uses.
More pixels are
not the whole story.
Resolution, bitrate, motion, and encoding choices all influence the result. A larger file is not automatically a better experience.
Read the note
Fast motion and detailed scenes place different demands on compression. Compare exports with the source, paying attention to fine texture, gradients, and movement.
Check both the picture and the sound. Keep an original copy before creating smaller versions.
Test the journey,
not just the file.
A smooth local preview is a useful first check. Network conditions and the playback environment add their own variables.
Read the note
Before publishing, test startup time and seeking on a slower connection as well as your own. Check captions and controls on a small screen.
This local inspector cannot measure a CDN, predict every device, or verify that a delivery service is available.
A LITTLE MORE CLARITY
Before you
press play.
Are my media files uploaded?
No. Selecting a file creates an object URL in your browser. The file is previewed locally; this page has no media upload endpoint.
Why does a file fail to preview?
Your browser might not support the codecs inside the file, or the file might be incomplete. The inspector can show the size and file type even when playback is unavailable.
Can this workspace convert or compress files?
No. It is a lightweight inspector and preview player. Use a dedicated editor or transcoder when you need to change formats, resize, or compress media.
Does clearing the selection delete my original file?
No. Clearing releases the browser's temporary reference. It does not edit or delete the original on your device.
