Zgemma H9 combo slow motion issue on some channels, kodi not playing videos

[dumitru.o]

hi

i am new to this forum and i've just received my Zgemma H9 Combo ordered from World of Satellite. Since i ve got the box (loaded with OpenATV 6.4) i am learning to use it day by day but i have encountered some issues that i don t know how to solve and, if they are because of the box or the software:

1. i have inserted my official CAM Irdeto from DigiTV DVB-C subscription that is opening all my channels but some channels have the image in slow motion all the time (not only when you change the channel ). for now i discovered the following to have this issue: AXN HD, Eurosport 4K and i also have some channels from the satellite (FTA) doing the same think, one example is Hotbird 4K1 channel on Hotbird 13 East. The signal on the DVB-C is 91% and on the satellite is around 47%. With the cable directly connected to my Sony Bravia TV (with the CAM inserted) the is no slow motion .


2. i have installed Kodi and added the videos from my SMB server (locally , no password) the library was loaded with all the movies but when i try to play one, screen goes black and the movie never starts.


I already have few days looking for a solution on these and could not find until now. Any help or advice would be appreciated

thank you

A lot of slow motion problems with 4K TV are the "enhancements" on the TV itself. On many brands it is recommended to turn off any picture smoothing features. On the LG tv I have it is called Trumotion - it will be called something different on sony tvs. Also I found noise reduction to be a huge problem. I have a SF8008 which has the same chipset as the zgemma H9 and the Hotbird 4K1 is fine. Just because the picture works fine when the feed is connected directly to the TV does not mean the TV is not at fault - there will be different picture settings for each input.

thanks for the suggestion. what you claimed i tested now and i am definitely convince the TV is not the issue and i will explain why:

- i set the output on the Zgemma to 1080p and i still have slow motion/glitches on that channel.
- i connected the HDMI cable to a different TV (Samsung LED Full HD) and the image is the same: slow motion/glitches

the Sony had a feature for the HDMI input which i set to both Full and Limited. no difference

so definitely it s something with the Zgemma H9 combo box

[ronand]

What are your output settings 50hz/60Z/Multi? The Hotbird 4K1 channel actually uses different refresh rates for different programs

[ronand]

Also Motionflow is the name of the feature on Sony TVs - turn it off.

[dumitru.o]

i have found the MotionFlow feature and turned if OFF. it also has a feature regarding the dynamic range of the HDMI input. i set to standard format (the other one was enhanced format )

the image is the same, no improvement

maybe i need to set up something in the zgemma box output

btw: i have installed the Egami image now and it s the same,

the output of the egami is set to 2160p30 with multi (the other options are 25,30,auto) and HDR Type to auto

since the behavior is the same on a Samsung LED full HD i believe the issue relies in the zgemma box. when you set the output to 1080P and still have slow motion image with glitches , this has to do with the processing of the image in the box and not with the output.

there is one channels FTA, AXN HD that a a huge delay between the audio and the video where the video is slow motion

It’s because it has a Hisilicon chipset, so the brief slow motion on each channel change will always be present, nothing to do with Image or TV etc.

Lets be clear on one thing - it is not slow motion. If it was slow motion the sound would also be slow and you would notice this immediately (unless the sound was out of sync). The problem is frames being skipped/dropped or incorrect refresh rate. You haven't confirmed what video output settings you are using so I can't offer any more advice on it. The hotbird 4k1 channel in the past hour has used 25Hz, 50Hz, HLG & SDR variants. It also plays content from the USA which could a problem. Try the NASA UHD channel on hotbird - its at 60Hz.

The OP is aware of that Andy - check the first post

[dumitru.o]

NASA TV UHD is broadcasting static images now you can t tell if there is a lag.

looking on Hotbird 4K1 now, i have slow motion with audio 1-2 seconds behind the video. i don t hear any glitches in the audio

LE i call it slow motion because i can almost see it in frame by frame, but i believe you got the point

[dumitru.o]

if the TV is the issue, then why do i have the same behavior when i set the output to 1080p and even connect the box to another TV which is not 4K?

[ronand]

Try posting a screenshot of your video settings.

[ccs]

Post #1 says he's using OpenATV 6.4, I don't know if that is still the case.

[dumitru.o]

NASA TV UHD seems to work fine but sometimes it has small glitches/slow motion video . i suspect this to be a signal issue

but the channels i have on DVB-C both have 91% and their picture is almost frame by frame with audio way before the video

I switched back to OpenATV

[ronand]

2160p30 will cause you lots of problems - most european transmissions are 25/50Hz. I think that mode is only for tv sets that are not properly 4k compatible. Is your tv capable of 50/60Hz?

[dumitru.o]

Yes, my TV is 60Hz compatible, i can watch NASA TV UHD 60Hz no problem with the dish connected directly to the TV.

Attached a small video of Eurosport 4K from the DVB-C tuner

Again no information - what is the refresh rate of Eurosport 4k and what are the settings on the zgemma? I don't have this channel here. Since most of use here use openvix there is no point using openatv as we cant help you with the settings. Install Openvix 5.3.034 and send a longer recording of Hotbird 4k1. Do not install the cam - just keep things simple. Set the video resolution to 2160p and refresh rate to multi.

[dumitru.o]

on the other page i posted a picture with my Zgemma video settings. i don t know the refresh rate of Eurosport 4K nor of the AXN HD channels.

i will install openvix image on slot 3 and return with answers to your questions

thank you

[ronand]

Those were the openatv settings which are different to openvix. Do not restore any settings - just scan the channels in on hotbird. In openvix if you press the OK button twice usually you can see the refresh rate (it depends on the skin used).

[dumitru.o]

switching to OpenVIX image impreved things:

- AXN HD channel works good now, as it should
- the output video settings have 50/60Hz settings now (instead of 25/30Hz on the OpenATV and egami)

but

still the image on Eurosport 4K is slow motion/with glitches
the image on Hotbird 4K1 is out of sync, sound is before image and image is like slow motion

LE: now watching Hotbird 4K1 with the content from "The Explorers" i don t see any issues

[dumitru.o]

i have quite a nasty raining now and the only 4K channel on Hotbird 13 East that is working it s the Hotbird 4K1. The signal is too weak for Nas TV UHD or Fashion TV UHD to check them out

at this point i can only see this problem with the Eurosport 4K channel on my DVB-C subscription that is 50Hz and has HDR. maybe one of this two is the reason for my slow motion image and glitches (both audio and video) that i have on this channel, inserting the CAM in the TV slots works fine though ...............

now i have installed Kodi but i can t make it see my network server.......box is connected to the router by wire, internet is ok, lan connection is good. will do more research here

[dumitru.o]

this is the issue i am talking about on HotBird 4K1

regarding Kodi, it still not playing the videos but the Plex addon works, it plays video but not all of them, guess it s a codec issue on Plex, not playing an 4K video from my plex server

LE: kodi plays the video just fine from the USB connected to the back of the box but won t start playing the video from the local server (SMB or FTP)

[ronand]

Its a very bad sync problem all right. I haven't had any such issues and I don't think anyone else has reported any such problem with the H9. Any problems I had were caused by my tv. Wait and see if any H9 owners see this thread and can offer some suggestions.

[dumitru.o]

i understand. thanks for all your time

[twol]

H9 doesn't have a lot of flash memory, especially with Kodi.
I would be tempted to insert a large memory SD card into teh H9 and use the H9SDManager (in ViX plugin) to format and move the root to the SD card - you then have as much memory as basically is on the SD card.
After this you boot from the SDcard by long press power button and then selecting the SDcard

[dumitru.o]

i think the H9 Combo has enough flash memory. does anyone with H9 Combo installed/tested Kodi app?

Yes, misread post - h9combo is fine
