2. Fast Playback

  1. After recording data in Live mode, the fast playback function can be used to play back the recorded data to see if the desired recording effect has been achieved. It can be used for scenes such as studio and virtual shooting. In the quick playback side window, you can also record, delete, add/delete notes, and descriptions of data. When recording data, you can also record reference videos. Below is a brief introduction to the various functions in quick playback:

  2. Open Fast Playback:

    • After recording motion capture data in Live mode, click the "Fast Playback Pane" button on the toolbar to open the Fast Playback panel (10.2.1).\

  3. Playback Data

    • In the "Playback Data" list, all files in the current working path will be displayed by their Cap file names. The files are sorted based on their recording times. Double-click on a Cap file for quick playback of its data.

    • During quick playback, a red text prompt saying "Fast Playback in progress" will appear above the 3D view, and the progress bar below will move forward (10.2.2).\

    • During fast playback, users can pause playback or drag the pointer on the progress bar. After dragging the pointer to a certain frame, the data displayed in the 3D view will synchronize with that frame.

  4. File Description and Remarks:

    • After double-clicking on a Cap file in the "Playback Data" list, you can add descriptions and comments to the file in the "Detail" section. The added descriptions and comments will be bound to the file. The next time the file is played back, the latest descriptions and comments will be displayed.

  5. Recording:

    • In the quick playback window, you can perform data recording operations by entering the file name. You can choose whether to automatically increment the file name. Before recording data, you can enter a description for the data, which will be bound to the file. Click the record button to start recording. After recording, double-click the Cap file that was just recorded in the "Playback Data" list. The description box will display the content entered before recording (10.2.3).\

  6. Delete:

    • Manage cap files in the "Playback Data" list. After double-clicking a cap file, use the delete button to remove the selected cap file. Note that except for the Mars file and the calibration file associated with this cap file, all other files will be deleted. Please use this function with caution, as once a file is deleted, it cannot be restored.

  7. Recording and playback of reference videos:

    • To record a reference video, first deselect the "Reference Video" checkbox in the quick playback panel. Then, click the record button in the quick playback panel or the third record button in the middle of the software to start recording.

    • Before recording data, you can add a description for the reference video in the description section of the quick playback panel. After recording, double-click the recording file to start playback and open the reference video view. The description entered during data recording will be superimposed on the reference video (10.2.4).\

  8. Record files:

    • After recording data in Live mode, a recording file will be automatically generated in the same directory as the recording file, which is also the software’s working directory. The file type is a text document (.log). The recording file will contain the name of the file recorded that day, the start and stop recording times, description information, and remarks information. The recording file name will be the date of the recording.

    • For easier viewing, you can drag the recording file into an Excel spreadsheet.

Notes:

During fast playback, templates cannot be added or removed. To add or remove templates, please exit fast playback first. Then, double-click the name of the played Cap file to exit fast playback and return to Live mode.

During fast playback, the system will automatically match the loaded Mars file. If the Mars file is not loaded, the MarkerSet will not be displayed in the 3D view.
