I did capture in this software.
However, CFR option does not work correctly, the average frame rate is now as set, but the minimum, and maximum frame rate was not the specified value, that is, instead of CFR, in fact it it had been captured in VFR.

The following is a log of MediaTab.

I tried x264, QSV and NVEnc, but the result did not change.
Remains in this state, and load them into the editing software, time code can not be read correctly with VFR non-compatible software, audio and video are out of sync.
Of its software "AviUtl" and so forth "Javie".

In addition, if you add a source in the game capture function, the preview screen of editing software called "Javie" can not be successfully captured has been found. Editing software stops responding when you start the capture.
Window screen of this software can not be captured in window capture function.
Therefore, we are using a full-screen capture by DWM now, but it is inconvenient.

At the same, it is not matter, but the software will not work properly with the 3 or less frame rate setting.
I think you have improved to work properly even frame rate 3 or less with them or so can not be set to less than 4 frame rate is whether it is all right.
Although people think that this setting is and not here to there.

I don't know about QSV or NVenc, but x264 is definitely running on constant frame rate, because I programmed it myself. The max/min may be deceiving, but it is CFR.

I know this because when I originally made the program, I did use VFR, and I remember quite clearly what results it gave, and it prevented video files from being usable within many programs. I then switched to CFR, and it fixed a ton of issues.

I confirm, OBS creates files with VFR. CFR option doesn't work. Neither with QSV, nor with x264.
I verified it with Mediainfo. Adobe Premiere creates correct files.
OBS version 0.653b 64 bit, Windows.
