Game Recording

• Improvements to drag and scroll behaviors when finalizing the beginning and end of a clip
• No longer warp the play head to the beginning/end of a clip when setting the beginning/end of a clip via the UI buttons
• Fixed a bug where using the hotkey to add a user marker would drop the marker at the wrong location
• Increase the minimum background recording time to 15 minutes, to give the user time to edit recent clips before the recorded video ages out
• Added a warning to the user if game recording has been turned off to prioritize broadcasting
• Ignore user marker shortcut key if game recording is disabled
• Improved reliability of saving/renaming of .m4s video segment files when antivirus software locks the files temporarily
• Added the ability to save a specific frame of a video as a steam screenshot
• Improved default naming of clip files to improve readability and sortability. Steam will also scan game state descriptions to apply to default clip filename, if available
• Fixed an exception thrown if the user canceled a clip save in the file picker dialog
• Updated message displayed when there is no recent other session where the user can send a clip
