KeepStreams is a tool, not a piracy platform. Always respect the terms of service of the streaming platforms you use. Download content for offline personal use (e.g., long flights or poor internet areas) where permissible. Do not redistribute or upload downloaded files.
According to the official changelog, this update focuses on stability and parsing. Here are the headline changes:
1. Improved DRM Handling (Widevine) Streaming services are constantly rotating their encryption keys. Version 1.2.3.7 patches the DRM decryption module to keep up with recent changes on Max (formerly HBO Max) and Paramount+. Users reported error 401 on certain titles in the previous build; this should now be resolved.
2. Fixed Amazon Prime "Black Screen" Bug Several users experienced a glitch where downloaded Prime Video files would play audio but show a black video track. The devs have isolated this to a muxing issue with H.265 codec streams. The fix in 1.2.3.7 ensures proper rendering in VLC and Plex. KeepStreams 1.2.3.7
3. Enhanced YouTube Playlist Parsing If you download large YouTube playlists (100+ videos), the previous version sometimes skipped random files. The new parser is more robust, respecting your "limit" settings and ensuring every video in the queue gets processed.
4. UI Polish for the Task Scheduler The built-in scheduler (useful for downloading overnight) now correctly saves time zones. A minor but welcome fix for international users.
Solution: This is an antivirus conflict. Temporarily disable Windows Defender Real-time Protection or add C:\Program Files\KeepStreams to your antivirus exclusion list before running the installer for 1.2.3.7. KeepStreams is a tool, not a piracy platform
Solution: In KeepStreams 1.2.3.7, the default subtitle output format changed to .SRT for better compatibility. If you want hardcoded (burned-in) subtitles, go to the download dialog window and select "Burn subtitles into video."
Version numbers tell a story. The jump to KeepStreams 1.2.3.7 signals a maintenance and optimization release. According to the official changelog and user reports, this version focuses on three critical areas: protocol adaptation, audio synchronization, and download speed optimization.
If you are using version 1.2.3.7, here are three advanced tricks to get the most out of it: Do not redistribute or upload downloaded files
Yes. Unless you are in the middle of a massive batch download, there is no downside. The DRM updates alone make this a critical patch, as older versions may stop working with major services within a week.
A persistent issue in versions 1.2.3.5 and 1.2.3.6 was a 200-millisecond audio desynchronization when downloading Hulu content at 720p. This has been fully resolved in 1.2.3.7.
