V8 NOVA framerate and AV out issue

Post by chector »

Hi everyone.

Some weeks ago, I reported an issue with videos with 50 FPS progressive in some channels or video player from a HDD.
After a couple of tests I discovered that the issue has relation with the AV output selected in the configuration.

Here's some examples:

1)
AV Output mode: 1080i PAL (25 fps interlaced)
Media played FPS: 1080i 25fps
Comments: Video is played smoothly (it seems to be 50 fps, because is 25 fps interlaced played with bob deinterlacing)
Result: Media is played OK

2)
AV Output mode: 1080i PAL (25 fps interlaced)
Media played FPS: 1080p 50fps
Comments: Video seems to be playing 25 fps deinterlaced WITHOUT bob, I mean, there is visual diferences with first example.
Result: Media is played NOT OK

3)
AV Output mode: 1080p PAL (50 fps progressive)
Media played FPS: 1080p 50fps
Comments: Video is played smoothly
Result: Media is played OK


As you can see, if you choose 1080p in AV output mode, the issue is resolved. But my LG TV has better image quality if the output is set to 1080i.
I think that the video has to be played with the same visual framerate in any AV out mode, because is not "confortable" to be changing the AV mode depending on the channel or media played.
