X1 Video quality seems poor

X1 Video quality seems poor

Today I received the X1 equipment and installed it, to my dismay, the video quality droped a lot from what I was currently watching.  I disconencted the old comcast box and installed the X1 (resumed watching HBO series "The Young Pope") and the change was not subtle, it is very obvious.  I have gone through all the settings, the box comes @720 and changed it to 1080i to surprisingly not much difference.  The picture looks awfully soft in focus and the dynamic range has dropped.  TV is setup through a Sony AV receiver hooked to the X1, a Blueray player and an Apple TV (which BTW the picture on the BR and ApTV still look as they always did). Looking at HBO through the X1 and switching to HBO Go on th Apple TV the difference is night and day, it used to be the oposite, meaning, the Live HBO through the old comcast box was better than th HBO Go. What gives?  I'm almost ready to return it and go back to the old comcast box, any ideas of what I might be doing wrong? It should've been a simple swap, one box to the other and not an overexpectation to retain the same video quality...

Re: X1 Video quality seems poor

X1 boxes require much better incoming and outgoing signal levels than older legacy boxes.

Assuming your setup is connected properly, if you are experiencing "pixelation" that strongly suggests your signal levels do not meet X1 spec. If your signal levels are within spec, X1's picture quality is just dandy.

You could always have Comcast send a tech out to troubleshoot your situation.

No pixelation, signal doesn't drop, interrupt, in short, no sign of signal level problem.
Thanks for the suggestion.

I understand that is difficult to describe a lose of video quality and for some reason there is no obligation or law for content providers to publish the technical spec on their service, so there is no objective backup for my experience.

It looks fuzzy and soft fucused with way less dynamic range meaning it can't resolve fetal on very dark areas or bright.
Is the total contrary of pixelation, the best description I can give is like if the picture was applied a Gaussian Blur filter

Re: X1 Video quality seems poor

I would get XG2 box and change box resolution to 1080p. The box makes a difference. I had nrg150n for some time and the box was freezing almost everyday picture quality was poor, it looked like downgrade. I had rng110 box before that and I was getting better picture quality than nrg150n but up to 720p couldn't set it higher than that. But when I got the XG2 box I was in disbelief. The picture quality is amazing big difference. The box works much faster than nrg150n and the default settings were 720p and I was happy that I could change the resolution to 1080p, and I did change it to 1080p. I see people here that complain about the picture quality, the first thing that comes to mind is a bad box and bad signal of course. You can have a good signal but your box must be good.

Re: X1 Video quality seems poor

My box is an XG2v2-P

 

Last thing I'll do is connect direct from the box to the TV with the HDMI cable supplied by Comcast to eliminate any othere variables, just TV and X1 box.  If same result, then is either bad box as sugested or poor quality as I suspect.  Maybe I'm just very sceptical, but recording 60+ hours of video on a 500GB drive (as I read somewhere on this forum to be the spec of the box) seems an unreasonable amount of compression in order to fit that amount of content, and if we are viewing from the output of that recoding in order to pause, rewind or ff, for me, is just an unreasonable degradation for the convinience. At least there should be an option of Video Quality vs recording time so people like me interested in the best quality possible and don't care about storage could get the desired experience.

 

However, I'll call Comcast to verify the signal strength...who knows if the box can't keep up and degrades the signal in order to provide service on a lower resolution (TV info says it is recieving @1080 but I understand that has nothing to do with the possible degradation the box could be applying), I can't see on this box a significant difference between 720 and 1080 settings.  Once again, the Apple TV feed looks way better than the X1...

Re: X1 Video quality seems poor

Calling Comcast to check your signals is partially pointless because phone reps can't see all critical X1 signals. The only person that is able to check ALL critical X1 signals is a Comcast tech who is actually on-site.

I have one Arris V3 DVR (connected to my best TV) and two XG2's. Personally I think the Arris DVR has notably better picture than the XG2 does. I tried an XG2 on my main TV and I couldn't deal with the drop in picture quality so I re-installed the Arris DVR in that location.

Thanks Rick for your insight. Yes, I meant for a tech to come to the house and do proper measurements :-)

So I guess you also noticed the video quality drop on this boxes right?

Re: X1 Video quality seems poor

At this point I will limit my answer to saying that I believe the X1 DVRs have better picture quality than any of the "Companion" boxes including the XG2.

My beliefs about X1's picture quality differ from most people in this forum.

Re: X1 Video quality seems poor

So, I did the direct connection box to tv... no cigar
Connected the box on the first split of the signal which is my bedroom(all this splits done by a Comcast tech on an earlier last year complaint about signal drop on my internet... tech confirmed it was a problem on the Comcast distribution hub that sits out of the house... they fixed it and then kindly reviewed my wiring and splits which they changed to theirs and confirmed levels in the middle of the optimal window). No cigar with box at the first split of signal

I enclose 2 photos the best I could of the same frame of the 2nd episode of young pope... first is HBOgo on a 720appleTV the second is X1... unacceptable... box goes back tomorrow

Re: X1 Video quality seems poor

I recently switched to the brand new box and X1 and I’m a videophile that works in post on films. I’ve also noticed the picture quality is worse. The best way I can describe it is it looks like a smoothing filter or denoiser is added to certain elements like skin tone. I cannot see and blemishes or pores on actor faces. And it looks bad! I can switch to Amazon, Netflix, or a Blu-ray and it looks like real 1080 resolution. Unfortunately the box menu does not offer any controls over the picture outside resolution. But I suspect a denoiser or digital smoother is set to on to make the picture less grainy and make faces look better. But it looks bad.

Re: X1 Video quality seems poor

The old boxes used to let you turn off noise reduction, etc. the new box doesn’t give you any control! This is horrible if you have a huge calibrated tv and are used to that very detailed true to the material image. I guess they dumbed down the box for the average consumer who like the artificially digitally cleaned look. Maybe it’s time to cut the cable!

Re: X1 Video quality seems poor

Just an update: I got on the phone last night with comcast and the rep on the other side of the phone admitted that they didn't know any technicalities about HD specs or the processes, only how to plug and play and reset the box.

So I got online to chat support, and the person I was chatting with did say they were aware of a problem, seemed to understand what I was talking about, and told me to go to the "standard" X1 Box, (meaning one iteration behind?), as there was no solution to the problem we're seeing on the new boxes. He said that even a tech couldn't get into the settings on the new boxes. I was assured he didn't mean "Standard Definition" by switch out to a "standard" X1 box and that it was still and HD DVR.

He said I would have to go into a service center and trade in my newer boxes for the older ones.

When I went to the service center, they told me all they had was the newer X1 boxes, that there was no such thing as a standard x1 box, only a non DVR X1 box. They said that the only thing standard could refer to is standard definition. They told me I would have to go to the older legacy box (non X1) if I wanted to change it out. I asked if it was still 1080 in resolution to make sure, and she said she didn't even know what 1080p or 1080i was! But another worker assured that it was still HD. He defended the X1, and said he used the X1 and it looked great. I told him it was a subtle thing that you wouldn't notice unless you had videophile standards or a large TV set to cinema standards.  I told him that even their TV in the lobby was exhbitiing the "smooth" loss of details. I also mentioned that other customers were noticing this and that there were the screenshots like the one above in this official thread that perfectly illustrate the problem. He abruptly turned and left, as if he didn't want to get into it.

Well I got the legacy box (and legacy 2nd box for an additional TV) andf hooked it up. They had told me it should all be fine once plugged in. But 20 minutes later it had not loaded anything. I called in to service, and the person I got told me that the boxes weren't registered in their inventory yet (as being assigned to my account?), and that it could take anywhere from 2 hours to 24 hours to activate them. she said she would call me back when it went through.


I'll keep posting if I make any progress.

Re: X1 Video quality seems poor

Okay, I am now watching The Deuce on the legacy DVR, and the image quality is back to the previous standard of sharpness without the strange blurring of colors and faces. I can see the texture on people’s faces and even the filmic grain.

The problem is the x1 box, not my TV, and not the signal. I’m happy to get the better image quality but sad to lose the voice operated remote control.

hi, what is the model number of that set top box? do you have other X1 set top boxes? how is that set top box connected to your TV? Do you pay for the HD technology fee? What is the output resolution set to for that set top box?

Re: X1 Video quality seems poor

I don’t work in the film/video biz, but I too loathe the X1 resolution filter. It looks like every frame has been Photoshopped with a filter called “cutesy, bland, ultra-smoothing filter for people who can’t tolerate the complexity of reality and would rather watch only plastic people or anime, preferably on opioids.”

it is probable that your TV equipment may need to be set up or features turned off etc. The video that you see is prepared by the producers and is unchanged as it is delivered to your device.

Re: X1 Video quality seems poor

I would guess that the reduced resolution is the product of signal compression.  If so, there likely wouldn't be any way to turn it off (what if everyone turned it off?).  As I understand it, X1 boxes aren't tuner boxes like we used to have which recieved all the channels at the end of the cable and decided what proceeded to the TV but the X1 box sends a request to a "main server" that responds with the one channel we want to see and it alone is streamed (that would explain the delay in changing channels and other sluggish response from the remote).  This frees up an immense amount of bandwidth and if they can compress that one channel down some more they save more bandwidth.  This feature wouldn't have an OFF setting either (what if everyone turned it off?). Who knows, maybe in the future one might be able to pay to upgrade to "TRUE 4K" service.  Awesome.

linear TV channels (numbered) are not IPTV they are each broadcast on a particular frequency and received by your TV. The tuning channel change delay is a combination of things, the request goes to a cloud server that tells the actual set top bot to change the channel.

Re: X1 Video quality seems poor

 If it is linear, it should be the same no matter what box you have, if it is VOD, X1 may be using IP-VOD at god knows what awful bitrate with their lousy MPEG-4, and the older boxes would still be using QAM-based VOD with MPEG-2 encoding at ~9mbps. The linear content in MPEG-4 looks like complete trash, there is no detail, the colors are crushed hard, and everytime there is a lot of motion, everything just gets blurry and you completely lose all the detail. It's amazing that Comcast hasn't had more complaints about the poor picture quality, it seems that most Americans are too oblivious to tell the difference, or they are watching on a much too small TV.

moving to mpeg4 from legacy mpeg2 doesn't degrade ithe signal. What is the output setting you have on your set top box? 720p? 1080i? 1080p?

Glad I’m not the only one that noticed this ridiculous problem. But frankly not surprised. 

 

I noticed the softness immediately. Tried letting the tv upscale, made no difference. It’s built into the box, which is absurd.

 

need a settings hack soon. Love the GUI and backlit voice remote but the pic quality is driving me nuts.

What is your TV model and what is your X1 model.  I'm sitting in the middle of Harvey's destruction and I don't see a "softness" on any of my three X1 DVR's.

What resolution is your DVR set to?

https://www.xfinity.com/support/cable-tv/x1-video-display/

It sometimes helps to unattach and reattach EVERY coax connection you can find from entry to the residence to the DVR.

I have the same model DVR and my Samsung TV doesn't have that issue.
