This part is frequently asked questions about editing.

1. Why the playback on timeline appears to be lagging or out of sync?

The choppy playback on the timeline occurs mostly by the files with a high Bit Rate. Most files coming directly from an HD camera or Drone have a high Bit Rate, such as MOV and MTS files. But generally, the output video quality will not be affected. As an alternative, you can try to transcode the imported videos to.MP4 before loading to our program. The whole re-encoding process will help you reduce the high Bit Rate and keep the video quality.

2. How to speed up or slow down a video?

4. Why the conversion process is so slow?

The conversion speed depends on not only the size, length of the source video, but also depends on the output settings. Meanwhile, it will be affected by the performance of your computer as well. There are things you can do to export more quickly.

① Optimized Media

To encode more quickly, the videos in your sequence should be optimized as much as possible before export. First of all, while using effects increases the time it takes to encode a video, it is suggested to cut down the unnecessary effects when in the editing phase. Besides, when exporting, please keep the Resolution, Frame Rate, and Bit Rate the same as those in your original video to shorten the encoding process for scaling. You can check the original parameters in Media Library, right click, and see the properties.
