Questions You May Ask

1. CFR or VFR, what’s the difference, which one to choose?
Constant frame rate and variable frame rate are two FPS standards. As the name suggests, the former one keeps a fixed frame rate value when recording while the latter one obtains an actively changeable fps value according to the real-time screen movement.

video parameters - cfr and vfr

VFR is widely used in mobile film shooting, (live) streaming video encoding, and many more for outputting a relatively smaller-sized video. But it’s not compatible well with video editing software like Adobe Premiere Pro, more likely to cause video and audio out of sync or other issues. So many people choose CFR recording for post-production or record VFR first and then convert VFR to CFR before the editing.

Another note on CFR is that sometimes even when you select one certain fps value say “30” FPS with CFR option, it’s still possible for you to get a VFR video due to the incompetent computer or encoder.

2. How to choose an appropriate frame rate Value?
Let’s take a look at some fps standards first: NTSC color encoding system that’s popular in the US and Japan adopts 30fps as its standard, and PAL in UK, Australia, and more countries delivers a frame rate of 25 fps. All general TV shows and movies are created and viewed at 24fps. That’s to say, choose any fps value between 24 and 30 is totally enough for a high-quality recording. If you want to lower the file size, you can lower it to 20.

video parameters - frame rate

Then why there’s 60fps option? Generally, under the following two circumstances can you pick 60fps as the target frame rate:

– You plan to record a high-powered PC game that’s played in 60 or higher fps.
– You want to make a slow-motion video after the capture. If the original fps is too low, the slowed video will look laggy.

3. What’s the bit rate of each quality option?
We all know that video quality is decided by many factors including video parameters and the recording environment. And bit rate is de facto one of the key parameters influencing the quality (where you can set from Menu>> Settings>> Video>> Resolution on Windows). Currently, only Windows users can use adjust the exact bit rate values.

And for Mac users, although the exact value is not adjustable, the bit rate values are automatically set for the best output quality.

We believe a decent screen recorder should serve for both noobs and pros. Therefore, if you prefer more parameter settings, please feel free to contact us and let us know your actual requirement.
