Playback stutters or stops

  • Operation
Playback stutters or stops
Timeline playback stutters or stops frequently. How do I solve this problem?

If the PC’s processor is overloaded or disk performance is not enough, timeline playback might stutter or stop frequently. Here are some reasons why this might happen:

1. Many video filters are applied.
2. Many key frames are set in an effect or in the layouter.
3. Placed clips have resolution, aspect ratio or frame rate different to the project settings.
4. Placed clips are in a format that requires a lot of processing (e.g. AVCHD, Uncompressed AVI or QuickTime).
5. Placed clips are read from lower performance storage like USB hard drive.

 

Suggested Solutions

I. Change playback buffer size

1) Choose [Settings] > [System Settings].
2) Choose [Application] > [Playback] in the left-pane.
3) Set larger playback buffer size than current size.
4) Click [Apply] and then [OK] button.

 

II. Render the timeline
Render the timeline via [Render] > [Render Sequence] > [Render Overloaded Area] (or loaded area).

 

III. Use GPU acceleration
If H.264 or H.265 file is placed onto the timeline, use GPU acceleration. Here is more details.

 

IV. Convert to an HQ file
Especially in the case of 3. or 4. above, convert the clip and then place the converted clip onto the timeline.

1) Right-click the clip in the Bin and then choose [Convert] > [Convert to File].
2) Converted clip will be registered into the Bin.
3) Place the converted clip onto the timeline. 
NOTE: If you use large frame size still images (especially TGA file), it is recommended that you re-size the images before importing into the EDIUS.

 

V. Play back from local drive
If the loaded clips reside on a USB hard disk, copy them to the local drive before loading into the EDIUS.

 

VI. Playback after buffering
Press Shift + Space combination. EDIUS will buffer video data to configured value. Once done, playback will start

 

VII. Use Draft preview mode
* Only available in certain version and edition of EDIUS
You can see drop down list at the right top of preview screen. Choose lower resolution (Full is original resolution).
