When I play mp4 videos, I see strange artifacts appearing randomly on the screen using WMP or Media panel. They are horizontal and they look like short white dashes. It happens when I watch youtube videos too and it tends to appears more on higher resolution videos.
I really hope someone can shed some light on the issue. Thank you all just for any comments because this is really bugging me and seems to suggest faulty hardware.
Got this test video from somewhere.

No one else encountered this problem?
This device just doesn't handle video very well at all, at least thats my experience. Especially video with higher bitrates. And yes I sometimes see artifacts, mostly "residue" of clips I've played just before like stuck frames at the borders of the video.
I have the edge problems too
But the artifacts/streaks of tiny short lines are appearing randomly in the screen area, not the edges. I am worried about having faulty hardware. I don't know how pda hardware function, but I have several desktop GPUs dying on me before.
Please guys, I really need more insight into this matter because if it is a hardware problem, I will be going down to the service centre soon.
Please just play a mp4 video and report your observations. I know it means nothing but I will be very grateful.
Have you tried running the vids through CorePlayer?
Have you ensured that the files aren't too big (res or framerate)?
Instead of posting vague information like "do you get artifacts" how about some real info about the files you are using.

I specified I get the problems with mp4 files on WMP and Media Xperiance Panel. The files are DVDs encoded with the tool from "[APP][REF]Full HD (800x480) video playback with acceleration" with the recommended settings(which I believe wouldn't be too high). Also, they lag horrendously with CorePlayer so I used WMP or MXP where they played smoothly EXCEPT with white - - - (dashes) appearing consistently but randomly. It occurs on all the videos I encoded this way when played on MXP or WMP.
In case you want some more details, one of the files played have the following details viewed with CorePlayer's Media Properties menu,
Video: AVC aka H.264
Video Size: 640 x 480
Frame Rate: 29.970
File Size: 20370KB
I thought I would not need to post much details because I believed people here would have at least tried playing videos close to the native resolution of X1's screen.
It seems the problem is only with my device and no one else here is having any problem I am having so I will head down to the service centre.

anybody? no one willing to help test?
I find no problems -am on stock UK Vodafone X1i and encode DVD's onto the SD card regularly (watch on train commute)
No problems with original FW and none since updating to RA2 via SEUS
Have just tried your posted "test" mp4 (crysiswarhead?) and definitely no white --- artefacts at all
It plays OK but is a bit laggy (only just noticeable)
The res is 800x480 which may have something to do with it (bit too high) ... I have been using 480x272 which works great and looks awsome (I use a commercial DVDripper -Aimersoft)
Good luck at the service centre!!!
Thanks for the reply. Unfortunate for me though, I always hate service centres. =(
More input please. =(
Same problem here.
Don't think it's a hardware thingy.. it's just not the ideal encoding for this little machine
I'm already happy I can play a normal mp4 / xvid / 'specially' encoded file on it.
Unless it's all over your image I do not think there is any succes in returning the phone.
they'll tell you it's not the 100% right codec format for the phone and will kick you out.
at least.. that's my thinking
Thanks mate for the response. I love this device and can live with this flaw, but I don't like the idea of having a defective hardware on the *inside*.
I can live with the problems I'm already having, scratch keyboard, wobbly slider, black paint dropping off but the fact that my x1 is havinga defective processing chip inside scares me so much.
Heading down to the service centre now...
There are videos that I encoded that play SMOOTHLY but will white flickers popping out all over. The service centre I know have a demo set, I will try playing videos on thatt and compare and hopefully convince those guys.
I'd like to know if Coreplayer will produce noticeably better video playback than the Windows Media Player or HTC Album Player that are already built in to the phone.
I don't care about other features or the number of different formats supported. If I take a simple .mp4 and play that same file with all three players, will CorePlayer have a faster frame rate or any other noticeable improvement?
Thanks for any info.
Coreplayer in my opinion is a great piece of software that you will really enjoy. It is a must for PPC!!

Coreplayer will be a lot slower than the built in apps, as it is unable to make use of GPU acceleration. People like it because it allows playback of a wider range of codecs and file types. The best video peformance is got by transcoding to .mp4 format and playing with HTCAlbum.
I used core player a lot over the past 2 months. It does have acceleration for mpeg4. I used Handbrake to encode up to 1500kbps and 672x378 Resolution. You can go higher in resolution, but you than cannot multitask without stutter. If I try to do the same with h.264, I am lucky to get up to 480x272 at 100% video playback.
Coreplayer cannot handle 800X480 mp4 videos without stuttering really badly. I am re-encoding some of the videos to 624 X 352 to see if it's more compatible with Coreplayer.
One issue I have with WMP and HTC Album is that they play 2.35 AR movies with the sides cropped and no black bars. I don't know if there's something I need to do when I encode or if that's an issue with the player. I cannot find any options to change this.
Coreplayer will display these movies correctly, but again, the stuttering makes it unwatchable. I am hoping the lower resolution will rectify the problem.
I really can't see any big difference between 624 X 352 xvid files and 800 X 480 mp4 files WRT sharpness and clarity. I don't think screen is big enough to make the distinction between the two resolutions noticeable.
Anything below 700w pixels it will run fine on Coreplayer.
Try out handbrake. It is free. Use FFmepg Mpeg4 files. You can use whatever bitrate you want but I wouldn't go past 1500kbps.
is coreplayer available for free or do i have to pay?
I have a question... I have core player for my device, and I've downloaded hand brake. Im wanting to make mp4's from my dvd collection. what do I need to do, and does handbrake contain everything I need to do this?

Core player is a pay application that is about 30 USD. It doesn't do mp4 videos as well as the built in apps as they use hardware acceleration. What core player does better is play other formats such as divx. I get 23 frames per second in high quality out of my 640x480 divx videos.
Although there is a Rhodium ROM on this site that does include it by default.
stupid question

I've got Coreplayer and it does well with divx, as you say. I just tried some MP4 videos and indeed they didn't play well. How can I get the built in player (not WM Player) to play something? I've removed all file associations from Coreplayer, which allows me to play an MP4 by clicking on it in File Explorer or Pictures and Videos, but is there a way to get the built in player to play an AVI file?

The stock player will only handle mp4, you just select your videos through the album and you're golden. I have a HD movie that plays with no stutter and DVD quality

FAB, thanks: now I know.
side note (purely conversational) -- I created a test MP4 with HandBrake, but there was no picture on the device, only sound (it plays fine in QuickTime on the desktop) -- back to fiddling with settings!
I use coreplayer since most of my movies are AVI(xvid). I haven't had a glaring problems with coreplayer other then the flickering blue screen when using TV-OUT. I really hate to trans-code videos.
If I really had to use TV-OUT for a video presentation, I found these setting removed 99.9% of the flickering. See link below:

***edit: I have been using other ROMs and they run fine with the settings listed on the link.***

I've not tried this with a video that is wider than 16:9, but certainly one that is narrower than the screen aspect ratio is played zoomed to full-screen by default, but this can be overridden quite easily. In HTCAlbum if you tap the screen you get a row of buttons appearing at the bottom, including pause and stop. The right-hand button controls zooming and stretching. By default a video is zoomed and cropped to fill the screen. Tap the right hand button once and it switches to stretching the video to full screen; tap it a second time and it switches to the correct aspect ratio (with black bars).
@combat goofwing
Are you using the old free CP or the new, $$ one? The free one stutters. The paid one works fine, set to Qtv. No transcoding, no stuttering. I just shoot my vids over and I'm gtg.

Wow. That was so simple. And here I was looking in the menus.
Thanks for the tip!
Accessing the built in HTC Album Player
Can anyone tell me how to access the HTC Album player? It just comes into action when I open a Video file, but can we access the program itself and adjust any settings etc.? One post says it only plays mp4. It plays my 3gp files too. Does it play any other formats?
Ok so I converted Batman Begins straight from DVD to 800x480 resolution using Aimersoft Video Converter Ultimate. I Converted it to an mp4 as xvid as the encoder. I've also tried H.264 as the encoder as well. I have tried everything to get the video to expand to the edges like the transformers movies did. I had kumar's lite rom but then switched to NRG's rom and its still doing it. I messed with the settings in the TCPMP player to see if I could force it to expand but it keeps staying cropped. I've included a sample pic to show you guys. Any help would be awesome!
*edit* after looking at the viewable size of the movie in the pic vs my screen size I would have to say its about the same size. But when you look at my screen as its playing the movie, it doesn't look that wide at all.
855-480 res with 16:9 aspect ratio?
ok sweet I think I figured it out. Another question. Looking at the size of the transformers movies (around 1.2gb each) and looking at the quality of the video, how could I make my rips the same quality but retain the same size of video?
.mp4 high quality codec try that setting
how did you figure out to get around the cropping?
I use core player and play movies. wmplayer does not do it for me. I use to convert movies for my omnia but you can adjust the aspect ratio on the fly. I usually do 16:9 but on the hd2 I have been choosing "fit to screen" and there is no cropping.
I notice on some avi videos vertical lines that are probably caused by upscaling - they are even more visible when using HDMI (because the screen is bigger). I tried several players. In one they were not visible but instead the picture quality was much worse.
I suppose the cause is scaling algorithm used by Tegra2 and there can't be anything done (other than upscaling the videos to 720p and converting to h264)? Or maybe there is a player that can do software scaling or allows selecting scaling quality?
Whatever file i play back skin tones on the files look way over saturated and there faces are very red i find this on anyfile that I use, hd, sd, mp4, avi, mov etc but video quality is fine when watching youtube and iplayer, how do I get rid of this, how do i convert files to show less of this oversaturation.
BTW I have a hd finding nemo trailer that looks incredible, so I know it is not all videos.
