Question / Help Offset Sync

[SAKTIKABEH]

My audio is 7 frames faster than video. How much do I have to set Offset Sync?

That depends on your framerate.

At 60fps, each frame is 16.67ms, so 7 frames is 116.69ms.

At 30fps, each frame is 33.34ms, so 7 frames is 233.38ms.

My video is 25 fps

 

[Narcogen]

25fps is 40ms per frame so 7 frames is 280ms.

Thank you

To compute the the time of one frame, compute the reciprocal value of the frame rate. You get the number of seconds. To get the value in milliseconds, multiply by 1000.
25 fps: frame time is 1/25 s = 0.04 s; in milliseconds: 0.04 * 1000 ms = 40 ms
30 fps: frame time is 1/30 s = 0.0333 s; in milliseconds: 0.0333 s * 1000 ms = 33.333 ms

I just do

Frametime = 1000/60FPS = 16.6666666666666667
FPS = 1000/16.6666666666666667 = 60FPS
