Best Video Setting for Smooth Video?

Anyone know what is the best setting for smooth video playback when viewing in Touch Pro 2?
I have download the Transformers 2 Trailer in FLV format and playback on my Touch Pro 2 but it seems to be laggy.
Anyone can advise me whether it is the video format problem or the phone memory problem as I have installed many applications.

Can only get on youtube through my Rhodium at work but isn't that video HD?
It's got a pretty fast processor for a phone but it's still only 533MHz, it can't playback HD content!

I've seen a couple of DivX movies (700MB each) on my TP2 and I have no lag issues...
In fact, I did had that, but back then I was using the player supplied with DivX codecs for Windows Mobile. Once I started using Core Player, the "lag" was gone.
I'll try that YouTube HD video in FLV format and get back to you.
BTW, what player are you using?

Yea i have no issues at all with any video format with coreplayer with the exception of mkvs.

I am also using Core Player for playing back the above FLV format file.

Sorry for the delay guys, but during my video speed testing , I found that although Core Player is supposed to play MP4 files (so they say), on my TP2 Core Player says "Player: Video codec (AVC aka H.264) not supported by the player!". So it seems that I have no H.264 codecs installed, which is strange because the H.264 codec is quite common on DivX. Well, I guess the movies I've been playing were not H.264 encoded.
This happened because I downloaded (without converting) both Transformers 2 trailers (LowRes and HD) from that link. The LowRes version came in FLV format (4MB), and the HD is a 33MB MP4 file. The FLV plays flawlessly without hiccups or delays.
I'm still searching for H.264 codecs for Windows Mobile, and will report back to this topic after installing and testing the video.

The HTC player will playback mp4's encoded with H.264, so long as they're Standard Definition with stereo audio.

I have download the same file again by copying the Videoplayback file in FLV Format from Internet Explorer Temporary Files Folder, file size is 12.2MB instead of 4MB.
How you can get 4MB and how you download the Low Res file? The playback is a bit jerky and not so smooth but after comparing the original one in YouTube, it is also a bit jerky and not smooth so there is nothing wrong with the Touch Pro 2 Playback as the problem lies on the source itself.

What you wanna do is get Coreplayer.
Encode your videos into Divx with vertical res. of 720 or under and keep the bitrate under 1500kb/s.
Great image quality with approx 112% playback speed.

I have used Coreplayer for playback.
Tried encoding "The Black Knight" Movie in the below format :
1) Width x Height (704 x 296)
2) Bit Rate (64kbs)
3) Audio Format (Lame MP3)
4) Frame Rate (23 frames/second)
5) Data Rate (1031 kbs)
6) video Sample Size (24 bit)
7) Video Compression (XVID)
There is some portion of the playback jerky and not smooth, any problem with the above settings?

You could try downloading that little encoding program.
It encodes your files into the perfect format for HTC Album. The user interface of the program is very easy and it encodes your files so that they play with full resolution and a good bitrate. Hope I could have been of help. All credit goes to it's creator.

I used a Firefox addon that "strips" the contents out of the pages (videos, sounds, SWF, ...). It can also be used to convert to other video formats while downloading, but I didn't use this feature as I wanted to test with the real deal.
I double-checked just now, and the smaller file (LowRes) is 4.76MB and it's fully functional and it plays 'till the end. The HD is 33,9MB. Perhaps there's a different file version when you stream directly from the internet... it doesn't make much sense, but I'm just guessing.
I didn't had time to continue searching for the right codecs yet. But I'll give it a go tomorrow. I'm sure I was not the 1st to experience this "issue" and the codecs "should" exist somewhere... so I hope.

Thanks for your recommendation and I recode the video again, it is much smoother playing over the WMP.
Will use this program to encode future DVD or Video for playback in my Touch Pro 2.

Play HD Videos on X1i ????

hello need a player who can play hd videos ( coreplayer, tmcpm, windows media, divix mobile etc ) dont work what can i do ? i cant play avis or some other videos on the x1 rom is toutchit v11 leo german please help me!

Let me Google that for you.

X1's hardware can barely play SD videos with acceptable quality/frame rate, let alone HD...
Another thing - the screen is 800x480 and it is not capable for any of the HD resolutions (720p/1080i/p). There are not enough pixels to display HD content. DVD (NTSC) video resolution is 720x480 and that's eventually the best you can get as a resolution off X1.

X1's hardware is capable (of SD), just use the normal WinMo Media Player instead of others which cannot make use of hardware accel.

Use the tool provided by XDA to convert your movies to mp4. Those can be played in high res 800 X 480 with wmp or the media xperience panel.

...i played video with more pixels than screen have...it was about (854*480) in .flv format, played in CorePlayer...i have few videos of that size, some of them plays fine, some of them are played in low frame rate(few per second only)...so its depends on hardware speed, not screen resolution...
armin van buuren-love you more.flv, is 864*480,and it plays very good...video is downloaded from youtube via savevid.com
I've posted links, so you can see...

I use mp4 format and this is this same what HD quality

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!

[Q] 720p video playback issue

Hello,
I'm having some problems about playing 720p videos from HTC Desire Z. It plays some 720p videos smoothly which are recorded by itself (also there is a fps problem in there, some are about 19fps).
I wonder which {container, codec} we should use to play 720p videos smooth. I tried with several media players like Vplayer, Moboplayer, Rockplayer and Android's default media player.
I tried some files. Here their properties:
Container: MKV
Video Codec: H264
Audio Codec: AC3
Overall Bitrate: ~4.5Mbps
Length: 71min
Size: 2.2GB
This was a concert video.
--
Container: MKV
Video Codec: H264
Audio Codec: AC3
Overall Bitrate: ~4.5Mbps
Length: 40min
Size: 1.1GB
This was a tv show.
Rockplayer can play this videos but not smooth enough. It freezes for 5-10 milliseconds at every 1-2 seconds.
Using stock 2.3.3 ROM and stock SD Card.
Phone can play 480p videos smoothly but I think it can play 720p videos since it can record 720p videos.
Thanks in advance.

The DZ isn't actually powerful enough to play 720p videos from an external source. I can barely play 480p AVI smoothly. MKV and MP4 are a total lost cause for me. Haven't tried after I installed Virtuous 2.0 and had it OC'd to 1.5GHz though.

As far as I know, DZ has hardware decoding for 720p videos. So it can play 720p videos and DZ records with 8mbps and encodes with h264 and its container is 3gp. Only difference is container. Maybe changing container will fix this but I tried with avi, mkv. Maybe I should try with 3gp container.
Anyone tried?

Tried with its trial version but it says "sorry, this video can not be played" when i try to play video which I mentioned at my first post (tv show one) and also another video which is a mp4 video.
DicePlayer can not play any video in the phone

I use Rock Player Lite and it can play MP4 vids properly. Granted, I just OC'd my DZ to 1.5GHz, and an MP4 file encoded in h.264 with an average bitrate of 1.5kbps plays flawlessly. At stock speeds the audio goes out of sync and artefacts get introduced. Haven't tried MKV files since I OC'd yet though. Software decoding in RPL.
Hardware decode basically is the same as the default media player, software decoding takes up more CPU resources, but is able to play more formats and containers.

I haven't found any way to reliably open mkv container on desire z. MX video player by far does the best job (and yes, I've used other players like rockplayer, dice player, etc) but it still plays 720p mkv h264 slightly choppy. 720p h264 mp4 plays fine with software and hardware decoder, while 720 avi xvid can play smoothly on a small overclock.
I try to avoid 720 anyway because the difference between 720 and 480 on a 3.7inch screen is barely visible to me lol

Exactly lol. As long as it can play 480 on the DZ it's more than fine by me. 720p on a 480x800 screen... ~_~
MX Video Player.. Never heard of it. Gonna search and try that out. How does it compare to Rock Player?

i really liked rockplayer for a long time until i found out mx player had software codecs tweaked for ARMv7. Check it out on the market, its free anyway lol

I tried mx player but still there is the same problem.
I also tried to change the container to mp4. PC plays well but when I try to play on phone, video is smooth but there is no sound and audio codec is ac3. Maybe the problem is here.
I tried with rockplayer using software decoding, there is sound but laggy video.

Try MX with SW. Works fine on any container and format so far for me.

The trick is to use video in the correct settings for the hardware decoder. If you do that then it won't matter if it's in mkv or mp4.
For the video portion, use baseline profile h.264 with the maximum bitrate (VBV) capped at 8mbps up to 720p
For audio, use AAC-LC in stereo.

I think so. But there is a problem when playing MKV files. There is problem after I changed container to mp4, though.
But the audio codecs of videos which I tried are not AAC. Maybe this causes the problem.
I don't know, how hard can it be to play videos which have AAC audios.

Use Handbrake to encode and it'll be easy to specify AAC for audio. You can use the iphone profile for encoding.

Hi again,
I've solved my problem. I use dice player which plays 720p mkv videos (even with ac3 audio codec).
I wrote here dice player can't play any video in the phone. That was a hardware decoding problem, I think. When I try to play an unsupported video format with hardware decoding, hardware decoding crashes and unable to play videos as it should be.
So, after that if I restart the phone hardware decoding comes back and plays videos perfectly.
Is this a common issue? If it is not should I do a factory reset to my phone?

To be honest, with our default 800*480 screen, we would not be able to take advantage of 720p quality as 720p is 1280*720 (Unless we stream it to a HDTV or Monitor). Re-encoding it to 800*450 is wiser to conserve file size as well
found this recommended settings at afterdawn for Handbrake or MEGUI. Tried it with rockplayer hardware decoding and it is smooth i used mp4 format

Video quality?

How good quality video playback can the Arc (S) handle?
in mp4, h.264 and ffmpeg?
I am thinking max bitrate for video/audio.

all the above,ffmpeg im not sure
hd mate,what can it be?surely 720
from the ARC

Very good quality just like every other high end device. Although Arc doesn't support avi or mkv files but you can play em with Rockplayer.

Very good, just like any other devices that capture [email protected]

last video I recorded was:
Audio:128kb/s
Video:6000kb/s (aprox, can go higher)
