M|Replay Version 2.3b72 (12 June 2025)

Warnings and Important Changes

This version of M|Replay introduces support for High Frame Rate (HFR) capture. Please note that this is still a work-in-progress feature, and we recommend using it cautiously.

Important: Before opening existing sessions with this version, make sure to back them up. When a session is reopened, the timestamps in the associated files will be rewritten, and you won’t be able to revert to the previous version.

Release Notes

• NEW: HFR Inputs/Outputs: Added the ability to create High Frame Rate inputs and outputs by selecting multiple sources and choosing “Create HFR input/output”.
• NEW: Multiple Playlists: Added support for multiple playlists, with the ability to switch between them using SKAARHOJ’s Time Spin (XC8) shuttle wheel.:

  • the shuttle wheel (the outer part) to select a playlist

• NEW: Export Status Window: Added a new window to show the status of ongoing exports, with options to cancel or reorder exports.
• NEW: Multiple Export Locations: Export to different destinations with custom file naming and angle selection options.

About the High Frame Rate (HFR) option

Requirements

• Requires all incoming signals to be genlocked, and using the same format and frame rate.
• Requires timecode embedded in the SDI signal. This may be challenging, but is the only way to be 100% sure of the sync between all the signals.

Limitations

• Currently this feature only works with Blackmagic-Design devices. Other devices will be supported later on.
• The number of formats and frame rates is currently limited (see screenshot). Ask us if you need to support one that is not currently in the list, as we will be adding more.
