Clipmaster Build 6 Manual (Updated 2020-06-13)

Back to project page

Setup

  1. Enable the Replay Buffer in OBS (Output -> Replay Buffer -> Enable Replay Buffer).
  2. Set a hotkey in OBS to save the replay buffer (Hotkeys -> Replay Buffer -> Save Replay).
  3. Open Clipmaster. Add your OBS recording directory as a replay monitoring path.
  4. Press your save replay hotkey to test that Clipmaster detects the created file.
  5. Left click on the clip thumbnail in Clipmaster to produce a file at output\output.mkv.
  6. Add a media source in OBS and point it to output\output.mkv.

It is recommended to enable the following options for your media source in OBS:
Restart playback when source becomes active
Show nothing when playback ends
Close file when inactive

Basic Usage

Clipmaster works by monitoring for video files produced by the OBS replay buffer, copying them into its own library, and then providing static file paths for you to use in your replay scene.

Selection mode can be toggled in the top left. In Single mode, output is processed immediately when you click on a clip in the library. In Multi mode, clips are added to a queue in the output panel, and are combined into one file when processed (highlight reel).

You can create multiple categories (tabs) to organize your clips. If you have multiple monitoring or output paths, they can individually be linked to a specific category.

Output Settings

Clipmaster provides a number of features to modify or enhance the output. You can enable up to six output paths (output1.mkv, output2.mkv, output3.mkv, etc) with different settings on each one.

Slow
Slows the playback rate of the output (e.g. slow motion). Uses x264 by default, so heavy CPU usage. NVENC can be enabled in settings.

Audio
Remove the audio or replace it with a custom track. Custom audio track can be selected in settings.

Clip Editor

The integrated clip editor allows you to trim your clips on-the-fly. The in and out timestamps are saved non-destructively, and only applied to the output as it is processed.

The editor can be accessed by right clicking on any clip. Clipmaster may freeze for several seconds the first time the editor is loaded.

In point cut uses the closest available key frame before the specified in point, which may be several seconds earlier. Out point cut should be frame accurate.

Automatic Scene Switching (“Auto”)

Clipmaster supports automatic scene switching via the obs-websocket plugin. When enabled, OBS will automatically switch to your designated replay scene when an output is produced, and then back to the previous scene when the playback duration of that output has elapsed.

Once you have installed obs-websocket in OBS and successfully connected, the Auto button will appear in the output panel.

Troubleshooting

If your OBS replay buffer files are not being detected by Clipmaster, make sure they have unique file names (for example by including timestamps) and are not being overwritten by OBS.

Consumer-grade Nvidia cards are limited to 2 simultaneous NVENC encoding streams. If you are already using both streams, NVENC will not be available to Clipmaster. If your output silently fails while slow is enabled, make sure NVENC is not being used by a background process (such as Nvidia ShadowPlay).

Known Issues

If automatic scene switching had previously been enabled, but Clipmaster is unable to connect to OBS, this may cause Clipmaster to hard lock when an output is processed. This can be fixed by either connecting to OBS and disabling the Auto button in the output panel, or by finding “Auto” in settings.json and changing the value to “false”.
