Smooth Playback

If multiple effects and titles has been added, real time processing may not catch up the timeline playback.

This real time processing is delayed due to the heavy data loaded on the playback operation. While playback is performed, the lines of the parts where rendering is required are displayed in red (overloaded) or in orange (loaded).

Performing rendering enables smoother playback.

Color Coding of Time Scale

Realtime processing sometimes cannot keep up when playing back a timeline. The line of the part judged as requiring rendering when playing back changes color.

The line colors indicate the following states.

Line color

Timeline state

No line

No clip exists.


A clip matching the project settings is placed.

Light blue

Playback is keeping up. (Rendering is sometimes required.)


Rendering option (load area)


Rendering is required (overload area).


Already rendered


  • Tracks with mute set to video parts cannot be rendered.

  • It is recommended to export the file using the exporter if you need to use rendered clips.

    Exporting in File Formats

  • When rendering is performed, a temporary file is created in the “rendered” folder. Make sure that there is enough disk space for temporary files before starting rendering.

Rendering Overload Areas of the Entire Sequence

Render all the areas that are judged as overload (red) in the entire sequence.

1) Click the [Render In/Out (Render Overload Area)] list button on the timeline.

2) Click [Render Sequence] → [Render Overload Area].


Rendering Overload Areas in the Entire Project

Render all areas that are judged as overload (red) in the entire project that comprises multiple sequences.

1) Click [Render] on the menu bar, and click [Render Entire Project] → [Render Red Area].

Rendering only Overload/Load Areas

Render only the areas that are judged as overload (red) or load (orange).

1) Right-click the line of overload (red) or load (orange) areas on the time scale, and click [Render].

Rendering Overload Areas between In and Out Points

Render areas judged as overload (red) between In and Out points on the timeline.

1) Setting the In and Out Points to the Timeline

2) Click [Render In/Out (Render Overload Area)] on the timeline.


Rendering Around the Timeline Cursor Position

Render only overload areas (red) or load areas (orange) around the timeline cursor position.

1) Move the timeline cursor to the area to be rendered.

2) Click [Render] on the menu bar, and click [Render Cursor Area].

Rendering Clips/Transitions

Perform rendering in individual clip or transition units.


  • If you perform clip rendering on a clip with alpha effect, alpha information will no longer be applied.

  • Keys, transparencies or transitions between tracks (effects set in the mixer area) cannot be rendered. In this case, take the alternate method to render a part of the timeline.

1) Right-click the clip to be rendered, and click [Render].


When a clip has been rendered

When a transition has been rendered, the center line of the transition changes color to green.


When a clip transition has been rendered


Exporting Video Clips from Timeline

Render between In and Out points on the timeline, and export only video clips as a file in AVI format. Exported clips are placed on the V/VA track.

1) Set the area of the clip to export from the timeline with the In and Out points.

2) Click the [Render In/Out (Render Overload Area)] list button on the timeline.

3) Click [Render and Add to Timeline (Between In/Out)].



  • Track areas set with title track clips and mute are exported as black clips.

  • Exported clips are automatically deleted when a project is ended while these clips are not in use in the project. If exported clips will be required for continued use later, either place them on the timeline or save the project with the clips registered to the bin.

  • To use exported clips in other projects, copy the file to another folder.

Exporting Still Image Clips from the Timeline

1) On the Recorder, display frames to be saved as still images.

2) Click [Clip] on the menu bar, and click [Create a Still Image].


Manually Deleting Temporary Files

Manually delete temporary files that are created during rendering.

Temporary files for rendering are saved temporarily in the “rendered” folder created in the project folder. Temporary files that are not referenced by a project are automatically deleted when the project ends, however, it is recommended to manually delete them when the “rendered” folder increases in size.

1) Click the [Render In/Out (Render Overload Area)] list button on the timeline.

2) Select [Delete Render Files] and click [Files that are not Used] or [All Files].


3) Click [Yes].


  • The temporary files created in the “rendered” folder can be freely edited (e.g. renamed, deleted or copied). However, temporary files such as [Render In/Out] that are referenced by a project cannot be edited. When a clip has been placed on the timeline by the [Render and Add to Timeline (Between In/Out)] function, the clip becomes an offline clip when the original temporary file is edited.
