NVX Frame Rate Matching

 

Working with a NVX setup and using Kaleidescape as a source. The encoder is receiving the proper feed whether it be 24P/60P depending on the source. On the decoder side, if I look into the stream being received I can see I am getting the proper frame rate (4K24P as an example) but it appears everything is converting to 4K60. If I manually choose the output resolution on the web GUI resolution I can get it to 24P as an example, but is there a setting that would make this automatic? Ideally I wouldn’t be converting frame rates or color space and just passing things directly from the encoder to the decoder but I am not sure how to have that done automatically.  Resolution is currently set to Auto on the output section of the web GUI.
 

As far as I know with the more advanced decoders ( eg the 300 series ) frame rate matching is not done automatically.   It’s a real pain imho.  I think that their reasoning is that crestron want the output to be continuous without all the blanking out that occurs with frame rate changes etc.  but it leads to terrible jitter so I hate it 

I have setup automation within crestron to active frame rate matching.  It’s not hard.  The source always reports its input frame rate. It’s on of the extensions.  I simply forward that to the framerate setting of the output nvx unit.  Simple.  But it does cause a resync of hdmi each time it changes.   

The other thing that annoys me is that the lack of 23.98 and 59.94 frame rates. So I have to use 24p for 23.98 sources.  Even the judder on the 23.98 to 24p frame rates conversion annoys me.   I wish they would include all the fractional frame rates because so many blu rays etc are 23.98

Thank you this is very helpful.  I am using Crestron Home for my setup but do have a 3-series processor integrated for some of the issues that arise within home.  I was able to program a solution here that seems to be working well and solving the issue.  Wish I would have posted yesterday as I ran around trying to make sure there weren't EDID issues in the chain/etc...
 

I haven't used NVX in a little while but is there no option to disable scaling on the receiver at all??
 

I don’t think there is any option to disable scaling from my recollection.  

The ironic thing is that the cheaper decoders eg d30 don’t have a scaler in built and so they output the original without needing any automation to make it match.
