Video Quality on Raspi 2 Mod B

Help and Support Raspberry Pi
1

Hey all,

I have a Raspi 2 Mod B with OSMC running on it. I am watching videos through an Epson EH-TW6600 Beamer with FullHD. While watching 1080p content I realized that there is a hard to discribe fuzziness … if the camera within the moving is fast the video is getting unsharp. If the camera is not moving or moving slowlier, the video is sharp again. I the settings I switched on that the refresh rate is changed upon starting a movie. So it is set to 23,976fps. What can I do to improve the quality of HD content or how can I check if the right resolution and so on is used?
I also have activated the licenses for WVC1 and MPEG2.

Maybe running in a different mode?

You need to login through SSH to be able to run these commands…

Too check the current mode:

tvservice -s

Too readout all modes supported by your beamer:

tvservice -m CEA tvservice -m DMT

3

At the moment I am not at home and Beamer is turned off, but the output is as follows:
osmc@osmc:~$ tvservice -m CEA | grep 1080
(prefer) mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
mode 20: 1920x1080 @ 50Hz 16:9, clock:74MHz interlaced
mode 31: 1920x1080 @ 50Hz 16:9, clock:148MHz progressive
osmc@osmc:~$

Hmm no 24p or 23,976p … maybe because the beamer is turned off, can check this in the evening

True, and prefered is interlaced, so 1080i instead of 1080p

5

uncool … :confused:
I will turn un projector tonight, start a movie and se what tvservice -m CEA/DMT is telling me and which mode is used.
At which config or position in the settings I can adjust that 1080p instead of 1080i is used?
And the Pi is always on, does it resync and change the resolution if the projector is powered on?

You should always boot the Pi with TV/projector powered up or it may not be able to read the edid and determine the correct supported modes.

If you always use the same TV/projector then you can save the EDID to a file:
http://kodi.wiki/view/Raspberry_Pi_FAQ#TV_is_not_detected_unless_powered_on_first

7

Hm yes it is alway the same device, I only power off the projector and raspi remains running.

8

Boot Pi with projector powered on first and report output of:

tvservice -s tvservice -m CEA tvservice -m DMT

Then do the same, but boot Pi with display powered off.

Ok, switched Beamer on and rebooted Pi afterwards:

then started a 1080p movie:

Now i powered off the Beamer and also the Receiver in between Pi and beamer and did a Pi reboot:

Beamer and Receiver back on:

so looks good till here
now started a movie and refresh rate does not change as above after reboot to 23,98 but from 60 to 59,94 … wtf :frowning:
osmc@osmc:~$ tvservice -s

I dont get it … restarted Pi with Beamer on and have same modes like before but this time it works again … But now there are only 17 modes, after my first reboot there were 27 modes … :confused:

And what about deinterlacing? It is set to automatic, how can I see wether it is being deinterlaced or not?

It looks like when the beamer is powered off you get the EDID from the receiver.
“tvservice -n” will report the name from the EDID that may make it clear who is providing it.

Anyway, follow the instructions from the wiki for capturing the edid to a file after booting with beamer already powered on.

Kodi will never use an interlaced resolution (unless it is the only resolution available).
Deinterlace should be automatic and should be very obvious if an interlaced source is not deinterlaced.
See http://www.100fps.com/ for examples of interlaced artefacts.
Try setting deinterlace to “off” and see how interlaced content looks.

Looks like you are right … at the moment beamer and receiver are powered of but he provides edid of my Yamaha RXV receiver …

And that one doesnt have mode 32 which is 24p … I will try saving EDID to file and will test again and report here. thx

Seems to work much better at the format, osmc desktop starts 60Hz, PAL TV switches to 50Hz and HD content to 23,98Hz, modes and device name stays the same even if Pi was powered on the whole time.

Will test in detail tomorrow or so but seems tgat saving the EDID did the trick and wron mode was the problem for the poor quality.
Thx for your help :slightly_smiling:

If so then mark it please as solved :slightly_smiling:
