Trouble displaying UHD videos on 4k TV - G4 Q&A, Help & Troubleshooting

Hi, I am trying to play UHD videos shot by the G4 on an LG TV that has 4K resolution (remember UHD and 4K are not the same thing). The video proportions seem to be altered into something narrower. I am using VLC media player and have already tried the "A" shortcut to experiment all the available formats, but none seems to bring proportions back to normality. I have also tried out all the TV available formats, with no success. When I play the same videos on my laptop, I finally get the right proportions. Any suggestion to solve this problem?
Thank you

How are you playing them? Are you using an USB stick connected to the TV or a PC? I had issues with playing some videos with the built-in player from my LG TV.

By means of 4k 60fps capable hdmi cable attached to a laptop

What player are you using? How powerful is your laptop? G4 records at a high bitrate, it can really stress your laptop. I suggest re-encoding them with a lower bitrate.

Bitrate is fully supported, the problem is with format / proportion not with performance.
Thank you

Like I said, try to re-encode the files from the G4.

Could you please suggest a tool for re-coding? Thank you

Handbrake is by far the most easier to use https://handbrake.fr/downloads.php. It also has versions for all major OS-es, I am using it for a while now on Windows (it also has multithread). It can also do HEVC (H265). Just make sure you select a high enough bitrate for H264 (talking from encoding 4K videos). Try with a smaller file when you perform some tests, I would recommend using about half of the bitrate the G4 produces (probably 15 Mbit bitrate should be enough for H264). For H265 I would recommend using 5 Mbit bitrate, this encoder is still new.

Video encoding settings?Please help! :-)

I'm trying for a while now to convert movies to be played on my desire.Right now I am trying using handbrake.However it just won't seem to play whatever I have thrown at it.
My average convert settings are something like this:
An H.264 .mp4 file @ 2mbps bitrate with mp3 or AAC audio @128kbps,resolution 800x480 or 1280x720.
I have also tried to play each converted video with RockPlayer but nothing changes.
Bear in mind that the only size limitation for me right now is fat32's 4GB limit.I use a Kingston 16GB class 10 SD.
Many many thanks in advance!
Strange, I've got an Avatar rip that I dl'ed and put straight onto the Desire that played with no problems, looks awesome as well. Plays through the default player or through Rockplayer as well
Sent from my HTC Desire using XDA App
Yeah,I am also trying this with Avatar.I have downloaded two versions,one 1080p that obviously doesn't play at all,and a 720p one that plays but is really really laggy.
Can you tell me more info on the copy of Avatar that plays ok on your device?
I do it in two steps:
1. PocketDivXEncoder, just to have a "clean" AVI in 640x480.
2. SuperC, no resize (I find PocketDivXEncoder better for resizing).
Video MP4, Codec MPEG-4, 15 Fps, 768 kbps
Audio AAC-LC, 44100, 2 channels, 128 kbps
Perfect, IMO.

Thanks for the reply my friend but that's not what I'm talkin' about...I want high quality when I watch movies.Strangest thing is that I try to make my videos have the same settings that the Desire uses for the videos taken with its camera.To no avail so far!
Also,if anyone uses handbrake I think it would be a more productive thread!
I'm using AVS Video Converter now and my files works flawlessly. The settings are H.264 [email protected], 720p resolution (or native WVGA, as you like it), up to 8000kbps (without any problem for Desire) bitrate, no CABAC, MP4 ISO v2 container. Handbrake lacks some advanced settings, maybe you should try to change it.
But dude,it's a paid program,Handbrake is free,that's why I use it.I will try to find a cracked version though...
@Pigbrother
Man,can you please share the settings you use for H.264 with me?I encode again and again and,although it does play on the Desire,it lags like ****!
I do a H.264 @3Mbps,but I am confused with the advanced settings of it and probably that's where it all goes fuzzy!
I managed to snatch a copy of Avatar with Handbrake that plays well,but it's MPEG-4 @2Mbps(although it seems that higher would play no prob).But H.264 is better,so I want that if possible!
Here they are.
I'm using the default player with hardcoded subtitles (you can select them in the advanced tab, bottom of the screen)
Dude,this is STRAAAANGE!
Following your instructions and settings pigbrother,I got a small length video(a 1080p trailer of Harry Potter 7 I downloaded from youtube),I converted it according to what settings you used with a 3250kbps bitrate and 720p and it played super smooth while having the best quality I'd ever seen on a mobile device!Then,I converted Avatar with exactly the same settings and it wouldn't play!I tried stock video player,mVideoPlayer and RockPlayer but none worked,it just said it couldn't open the file.The only thing I can think of is that there is some sort of limitation regarding the size of the file to be played(mine was 3,8GB),because the only playing copy of Avatar I got was an exactly 2GB big one I got with Handbrake.
Please guys,If you can think of something help me!
Thanks!
So,guys,this is interesting.I made another copy of Avatar using AVS and I used some higher profile settings(like CABAC) to make an 720p H.264 mp4 file @4Mbps and checked the option to split it in 2000MB files.Total size is about 4,8GB for 3 files and it plays like heaven!The picture of it is the absolute best I've seen until now!
So guys,there is no meaning in disabling all those advanced options as they only give better compression and quality(while making the process of conversion slower however,mine took 7:30 hours with my E8400 Intel Core2Duo).You should only put a limit to the bitrate so that the output file doesn't get bigger than 2GB.
So that's it!Now,if there is any way to make the conversion using the PCs GPU which will make it far faster I'll be happy!

All about Videos(Conversion softwares, formats,Video Players)

Hi guys I am starting this thread because i didn't find much information regarding:
1)Video conversion softwares.
2)Best video formats for obtaining least size with highest possbile quality
3)Converting full HD videos to be able to play on defy with the best quality
4)Best players available for defy to play good quality videos smoothly.
I have started experimenting on this..
I am using total video converter for conversion and Moboplayer for playing.
Keeping Resolution 854x480 and Video bit rate 2500Kbps.
I get a file of size 55Mb .avi(H.264) after conversion of a 113Mb .mov(1080p) file.
I want you people to tell me your methods and softwares for doing this.
I hope this thread will help all people having trouble in playing HD videos on their Defy.
I will keep updating whenever I find something new and useful info.
Thank You.
For the Defy, my favorite video conversion software is Handbrake.
It's free and it's the best at letting me crop 4:3 format videos the way I want easilly.
- Choose the 'iPphone Legacy' format
- Uncheck 'large file size' and 'Iphone 5G support'
- Select your file name/location and resolution [make sure that keep ratio is enable];
- Choose auto or set your custom cropping
- Let it do the re-encoding; it is very fast: it keeps both my cpu cores at 100%
The Defy will basically play anything smaller or equal to its native screen resolution but most of the time, I find that 640x360 looks just fine.
What is the best container for 720p movies? I tried .mkv but Software decoding is too slow...Video is chopy but sound is good.
I made my own HD video with Defy camera (auto packed it as .3gp), and when played it was also chopy and even slower than .mkv :S
mp4 is native
Ok, that is cool...I have MS2Ginger1.0 with 720p video shootin, but I can't change format when shootin a video...It saves it like .3gp :S
That just sucks then

Unable to play 4K Videos on my Mobile!!!!

LG G4
Tried playing 4K video on my G4 and it could not handle it... only sound kept coming... *.mkv format is what I tried.
INstalled MX Player with Customer DTS codec support.. tried all..nothing helped!!!!
Please provide some help and I downloaded videos from Youtube 4K Resolution ones...
So it sounds like you downloaded a video but you don't have the codecs.
Is this happening with all videos?
I would imagine that you are able to play them just fine on youtube?
I hate to break it to you, but you won't get quicker/better responses based on how much larger you make your text.
Yes 4k does not play and but 2k(1440p) plays fine in ma youtube... But once downloaded cannot play 1440p videos using any player.. tested mx, dice, bs and stock player too
I have found the issue in playing the 4k and 2K videos I downloaded from Youtube.
I downloaded MKV format which was the culprit... 2k and 4k mp4 formats work fine... mkv works only till 1080p.. may be a codec for mkv should be released for ARM V8

I tried 4K video on VLC with enabled Full HW acceleration and without single lag
test video here: http://demo-uhd3d.com/fiche.php?cat=uhd&id=149'
every video with 60+MB/s bandwith (ofc depends on storage speed, on my Samsung 32GB EVO+ even 70MB/s plays without problems) is laggy 10 bit HEVC is not playing H264 works without problems
YT 4K videos works also on VLC...
same problem
Only 4k video with h264 of codec
Maybe it's too late to reply but the fact that LG G4 only supports 4K video in h264 (mp4) format. You should convert the video with your PC (i recommends Handbrake) select 2160p profile and do some edits or you can convert with any software. Make sure the files converted to mp4. The only one reason if you downloaded a 4k youtube video and it can't directly played on G4 is just because youtube codec for 4k isn't h264 as like 1080p or lower but webm.

cannot play downloaded youtube 4k videos smoothly with mx player and default player !

hello all... i m facing a strange lag in my htc m9. currently running Viper one m9 4.3.0. but i have tested with stock rom also , that, i cannot play 4k videos smoothly which i'have downloaded from youtube. i moved that video to my device memory, then opened it with mx player. that video is only playable with mx's SW mode but veryyyyy slowly. both the HW/HW+ mode says "not supported" what can i do to play those 4k videos smoothly in my device? please..T.I.A.
The M9 have an 1080p display, so 4k videos, even 2k videos won't look better than 1080p videos...
You can download the videos at full hd resolution from youtube, you will save space too.
The problem is mxplayer. Because it is downscaling the video from 4k to 1080p on the fly via software it can only convert so much in so little time and that causes it to pause while it converts.
You will find that youtube servers do the bitrate at their end so even if the video says 4k, if you play it via the YouTube app you'll only get the max resolution that your device can handle, in this case 1080p as that is all your device can do.

What about vlc player?
It might work, it might not..

Gen1 Fire TV - Max bitrate for HEVC

So, HEVC files of 720p along with DD play fine. I know it's using the CPU to decode, but it works, and if it works, it's good with me. I'd like to try out 1080p, and the first file I tried stuttered a little here and there. I was wondering if anyone knows a good bitrate to encode to, that would include DD, that would not stutter as much? I'm sure someone's tested it... otherwise I'll do a bunch and try them out over the weekend.
thanks
This site has a collection of videos in different bit-rates you can use to test:
