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.

Blue

A clip matching the project settings is placed.

Light blue

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

Orange

Rendering option (load area)

Red

Rendering is required (overload area).

Pink

Rendering job has already been registered to the Render Service, or rendering is in process in the background.

Green

Already rendered

  • Rendering is judged based on the remaining buffer set by [Application] in [System Settings] → [Render], and a red line is displayed for overload areas when the remaining buffer is less than the preset value.

    [Render]

  • When data such as CG animation has been placed on the timeline by one frame at a time as consecutive still images, rendering the range will not lighten the load of playback processing. In this case, use the [Render and Add to Timeline] item to replace with the exported clip.

    Exporting Video Clips from Timeline

  • Rendering is enabled even if the clip becomes out-of-position by a ripple delete, for example.

  • In the following cases, the color of the line of the time scale returns to the state before the rendering process started.

    • The rendering job has been canceled by operation from GV Job Monitor.

    • The rendering process has failed.

Note

  • 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

  • Temporary files generated at the time of rendering are saved in the following folder temporarily. Make sure that there is enough disk space for the files before starting rendering.

    The “rendered” folder in the folder specified from [User Settings] → [Application] → [Project] → [Rendered File]

    Manually Deleting Temporary Files

  • Files generated by [Render and Add to Timeline] are saved in the following folder. Make sure that there is enough disk space for the files before starting rendering.

  • Make sure that there is enough disk space for the files before starting rendering.

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

Manually Deleting Temporary Files

Manually delete temporary files that are created during rendering.

By default, temporary files for rendering are temporarily saved 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.

  • You can set the save destination of temporary files from [User Settings] → [Application] → [Project] → [Rendered File].

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].

Alternative

  • Click [Render] on the menu bar, and click [Delete Temporary Render Files] → [Files Not Used] or [All Files].

  • Deleting unused files: [Alt] + [Q]

3) Click [Yes].

    [Render]

  • A temporary file is created in the following cases:

    • When a clip has been exported from the timeline

    • When whole or part of the timeline has been rendered

    • When a clip has been rendered

  • Files created by [Render and Add to Timeline] and saved in the “RenderAndPaste” folder will not be deleted even if [Delete Render Files] is executed. In case there is a shortage of capacity of the “RenderAndPaste” folder, delete the files manually.

Note

  • The temporary files created in the “rendered” folder can be operated (e.g. renamed, deleted or copied). However, temporary files referenced from a project, such as [Render In/Out], cannot be operated.

Exporting Still Image Clips from the Timeline

Video images in the selected preview window (Player/Recorder) can be exported as still image clips and registered to the bin.

Example:

To export the frame displayed on the Recorder as a still image

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

2) Click [Create a Still Image (Save as)] on the timeline.

  • The [Save As] dialog box appears.

3) Set a file name, save destination, and [Save as type], and then click [Save].

  • The still image is saved in the specified folder, and the still image clip is registered to the bin.

Alternative

  • Exporting still image clips from the timeline: [Ctrl] + [T]

  • Click [Clip] on the menu bar, and click [Create a Still Image]. The still image is saved in the same folder as the project, and the still image clip is registered to the bin.

  • Video from a deck also can be saved as still image clips.

  • The aspect ratio of still images sometimes is output different from that of the original image depending on the frame size. To output correctly, set to correct the aspect ratio. The settings of still images to export can be changed by [Importer/Exporter] in [System Settings] → [Still Image].

Draft Preview

Reducing image resolution or bit depth for preview improves the performance of real time playback. Although the preview image quality becomes lower, it reduces the load on PC and you can edit data comfortably.

Make use of this feature when you apply heavy-load effects such as [Mask] and [Layouter], or when you play the timeline where high-resolution clips such as 4K are placed.

1) Click [Preview Quality] on the menu bar, and select an item.

  • The image quality for preview will be changed according to the selected item.

[Full]

Previews video without changing the resolution and bit depth.

[Full 8bit]

Previews video with the original resolution maintained but with the bit depth changed to 8 -bit.

This is displayed only for projects with video quantization bitrate of 10 -bit.

[1/2]

Previews video in 1/2 of the original resolution.

[1/4]

Previews video in 1/4 of the original resolution.

[1/8]

Previews video in 1/8 of the original resolution.

[1/16]

Previews video in 1/16 of the original resolution.

  • Click [Settings] on the menu bar, go through [User Settings] → [Preview] → [Playback], and add the check mark for [Show full quality when Paused], to enable preview in the original image quality when playback is paused.

  • When proxy editing is started while [Preview Quality] is set to [Full] or [Full 8bit], the setting is automatically changed to [1/2]. When proxy editing is started while [Preview Quality] is set to lower than [1/2], the setting is maintained. After proxy editing is finished, [Full] is applied for [Preview Quality], regardless of the original setting.

Note

  • Depending on the [Preview Quality] setting, the timecode or level meter in the status area may not be displayed.

Playing Back Video with Effects Applied Smoothly

When heavy-load effects such as [Mask] or [Layouter] are applied on a clip, real time processing may not catch up and the timeline may not be played back smoothly.

Draft preview can be used in such a case. Although the preview image quality becomes lower, it does not take time for converting resolution or bit depth, and the timeline can be played back quickly. If you need to check image details, adding the check mark for [Show full quality when Paused] can let you check the image in the original quality when playback is paused.

Playing Back 4K Video Smoothly

Draft preview is effective in playback of timeline where the data amount is large due to a case such as heavy usage of high quality 4K image clips.

For example, when [1/2] is selected for [Preview Quality], 4K (3840x2160) video is displayed in the image quality equivalent to Full HD (1920x1080). If you edit video on a notebook PC, selecting [1/4] and previewing in full screen can maintain an adequate image quality.

By using the draft preview, you can handle high-quality image sources regardless of the performance of your PC.

  • Draft preview functions effectively in the following commonly used formats.

    Sony RAW, Cinema RAW, Cinema RAW Light, Avid DNxHD/Avid DNxHR, Apple ProRes, RED, Motion JPEG, JPEG, Grass Valley HQX

Frame Skip Playback

By thinning frames for preview, the performance of real time playback improves.

Make use of this feature when you apply heavy-load effects such as [Mask] and [Layouter], or when you play the timeline where RAW data clips are placed.

1) Click [Skipped Frames] on the menu bar, and select an item.

  • The image quality for preview will be changed according to the selected item.

[Full frames]

Does not thin out frames for preview.

[1 frame] - [30 frames] *1

Thins out the specified number of frames for preview.

By increasing the number of thinned-out frames, the load on the PC during playback will be made smaller.

*1 Select [1 frame] - [5 frames] to specify by1-frame unit, or select [10 frames] - [30 frames] to specify by 5-frame unit.

  • [Skipped Frames] in the multicam mode can hold specific setting values which are different from those in the normal and any other modes.

  • If [Skipped Frames] is set to an option other than [Full frames], the timecode, closed captions, and other information to be displayed on the preview window also appear reduced according to the number of thinned-out frames.

  • If a clip on which [Motion Blur] is applied is played by frame skip playback, the motion in the thinned-out frames will not be used.
