Topic: Frame rate: variable + playback issues

So, I'm a bit confused by this Mediainfo:

How come frame rate is variable rather than fixed?
And for some reason my Blu ray player (specs here) cannot play the output videos. I wonder what I'm doing wrong. Could you please help?

Re: Frame rate: variable + playback issues

Bluray players are very sensitive to profile level and advanced settings used in H.265.
I see you are using x265 coder and profile Main@L8.5@Main. Perhaps it is not good for your Bluray player. Try another more standard settings when encode.

Variable framerate can be a result of combining two videos with different framerate into one video.

How your questions are connected to SVP? Are you using SVPcode?

I bought SVP and am trying to transcode video collection to 60fps for playback on TV.
I'm not sure how to change the Main@L8.5@Main setting. Could you please help?

Re: Frame rate: variable + playback issues

First try to use H.264 instead of H.265
Perhaps it will be good enough for your tasks.
