One practical example
A launch film, ready for the publishing team
Suppose your approved film is a 24 GB master. Put the master, a smaller review export, the subtitle file, and the poster image in clearly named folders. In the delivery note, point the publishing team to the master and tell them which export is only for checking the cut. That small explanation prevents the wrong version from becoming the public launch video.

From start to finish
A clear handoff at every stage
- 1
Prepare
Export the correct cut and verify picture, sound, captions, filename, and duration.
- 2
Package
Add the master plus any agreed subtitle, artwork, checksum, or readme files.
- 3
Upload
Keep the device awake until Transfer ready appears and use only the access controls the delivery needs.
- 4
Confirm
Tell the recipient the format and size, then keep your backed-up master until they confirm the download works.
Prepare the work
Make the delivery easy to understand
Label the stage of the video
A review export, camera original, mezzanine file, and final master are not interchangeable. Put the stage in the title and filename so a client does not publish a low-bitrate review file or mistake an old cut for the approved master.
Check the whole delivery, not only the picture
Play the start, middle, and end. Check frame rate, resolution, color, audio channels, loudness, captions, and any separate subtitle or artwork files. Include a short readme when the recipient needs a particular player or post-production application.
Prepare for a long upload
Large masters may take hours. Upload from a local drive, connect power, prevent sleep, and use a stable wired connection when possible. TransferSize keeps confirmed parts and can retry a failed part while the tab and upload session remain open.

Tell the next person what happens next
Treat preview as a convenience
Supported browser codecs can show a quick preview, but professional codecs and unusual containers may not play in every browser. A failed preview does not prove the original is damaged; download it and test it in the correct player.
Choose transfer or streaming deliberately
A transfer gives the recipient the original file. Live Relay is for an existing authorized HTTPS HLS source and does not convert a master, transcode video, or create additional quality levels.
Make the next person’s first five minutes easy
A video package should answer the questions an editor or publisher will ask before opening it: Which cut is approved? What are the resolution and frame rate? Are subtitles embedded or separate? Is this stereo or a multichannel master? Put the answers in a short readme beside the files.
- Open the delivered master in the intended player after downloading a test copy.
- Include linked media when delivering an editable project, if agreed.
- Leave enough upload and download time before the publishing deadline.
Want the technical detail?
A file extension describes the container, not every codec inside it. A MOV or MP4 may download correctly even when the browser cannot preview its video or audio. TransferSize does not re-encode the original download. For long uploads, keep the browser session open: a failed part can retry, but closing the tab is not a dependable overnight pause.
Questions
Questions people ask
Will TransferSize reduce video quality?
No. The recipient downloads the video file you selected; it is not re-encoded into a smaller chat copy.
Why can the recipient download a video that will not preview?
Downloads and previews are separate. Their browser may not support the video's codec or container.
Can I close the tab and resume tomorrow?
Do not rely on that. Part retries work during the active upload session, so keep the tab open until completion.
Does Live Relay turn my uploaded file into a stream?
No. It only passes through an existing authorized HLS source.
