2.8 & 2.81 - WebM / VP9 Encoding error: Additional information: g_timebase.den out of range Using either Blender 2.8 or 2.81 when trying to encode a video using WebM/VP9 I get the following error:

Additional information: g_timebase.den out of range [1..1000000000]


I've tried a variety of containers in 2.8 including the previous workaround using "Matroska". And I've also tried just WebM encoding preset. Every attempt results in the same error mentioned. 

Is there somethign else that I'm missing?
The WebM/VP9 Container and Encoder only worked after I had selected a Dimension preset. Then afterwards readjust the render scale percentage and frame rate.



Does this solution make sense? No. But it worked with two different files I had been working on. Defining the dimensions manually for some reason caused the error previously mentioned and also the error, 

CQ level 0 must be between minimum and maximum quantizer value (2-31)

which I received when setting the "Output quality" to "Lossless".
