Setting up a source also is slideshow-like and saving changes of seource properties may take up to 6 seconds - it is synchronized to the fps. If you press stop again to force stop, you might lose some of the last frames.Īlso be aware the the preview of OBS also works at 1/6 fps if you enter this fps value. If it needs to record another 19 frames, it takes up to 19*6 = 114 seconds or almost 2 minutes until the recording stops gracefully. The file itself will be rather small, since it will contain only 600 frames.īe aware that if you press the "stop recording" button while recording with 1/6 fps, it may take a few minutes until the recording actually stops, because OBS can only stop about every 20 frames. Set Numerator to 1 and Denominator to 6.Ī video recorded with these settings will play normally (1 hour) in any media player and look like a slideshow with changing the image every 6 seconds. You can enter this fps in OBS as "fractional fps value" in Settings->Video. This is 600 frames / 3600 seconds = 1/6 fps. If you record more, the additional frames would be dropped, so you don't need to record more in the first place. That means you need to record 600 frames into your one hour source video.
So 10 seconds with 60 fps are 10 * 60 = 600 frames.Īnd you want a speedup factor of 3600 seconds / 10 seconds = 360 I suppose you want the timelapse video have 60 fps. You want to record one hour and timelapse this into 10 seconds.
