Telegram delivery is more than uploading an MP4. CastLiveRec tracks each completed recording so retries do not send mismatched fragments.
Player cover and contact sheet
Each video receives a single-frame player cover so Telegram displays a useful preview. The contact sheet is a separate image sampled across the recording with timestamps. It helps you scan the live without seeking through the entire video.
Both belong to one Telegram album. CastLiveRec sends the complete set so recipients do not receive the video in one message and an unrelated frame grid later.
Large recordings
When a final file is too large for one Telegram video, CastLiveRec creates ordered parts. Every part keeps a cover, and the contact sheet remains in the same album.
Duplicate protection
CastLiveRec protects each catalog request against duplicate delivery. A second click shortly after a successful send returns an “already sent” response instead of filling the chat with duplicates.
Why verify the complete album?
CastLiveRec verifies that the video parts and contact sheet belong to the same completed recording before delivery. This check prevents incomplete albums after an interrupted upload or retry.
Can I forward the album?
Telegram provides normal forwarding and save controls. Whether you may redistribute the content is a separate rights question; public source availability does not remove creator copyright or privacy obligations.
