VFR (Variable Frame Rate) vs. CFR (Constant Frame Rate)

You can change the frame rate mode by clicking the [...] button in the video format settings.
FPS settings: VFR and CFR
  •  1   Use VFR - Variable Frame Rate (Recommended)
    • VFR is a very efficient recording method which allows you to get small file sizes with the maximum FPS which the recording target can obtain. For example, even though you select "60" FPS at the video settings, you will get a "variable 40FPS video" if you are able to get only 40FPS while recording.

  •  2   Prefer CFR - Constant Frame Rate
    • VFR is much better than CFR. However, some video editing software such as Adobe Premiere doesn't support a VFR video. In this case, you have to choose "CFR". If you select "60" FPS with the CFR option, you will normally get a "constant 60FPS video".

    However, even though you select 60 FPS with the "CFR" option, you will get a "VFR" video if your computer/encoder is not good enough.

* Choose "VFR" for media players

Most media players and some video editors support VFR (Variable Frame Rate), so please choose "VFR" to enhance the recording ability and reduce the video size.

* Choose "CFR" for video editing software

To edit the recorded video with editing programs such as Adobe Premiere, Camtasia, CyberLink's PowerDirector, Magix Movie Edit Pro, Lightworks, Corel VideoStudio Pro with the MP4 container, choose "CFR".

* Caution) If the encoder's performance is not good enough, the video will be saved as VFR and you could have the video and audio syncing issue. In this case, you have to use the "Motion JPEG" and "PCM" codecs.
If you have the syncing issue with the "Motion JPEG" and "PCM" codecs, you have to reduce the video resolution of the recording target.
