Movie Trailers For N900
 

In this thread you will find movie trailers optimized for the Nokia N900 converted with attention to quality. These are trailers that I find interesting for whatever reason.

Each trailer that I convert is from a 1080p source and tested on my n900.

Edge of Darkness - Trailer 1

IronMan 2 - Trailer 1

RobinHood - Trailer 1

Star Trek - Trailer 3

The Dark Knight - Trailer 2 - by Slender

Toy Story 3 - Trailer 1

Zombie Land - Internet Trailer

Converting the trailer at this level of quality is a multi-step process involving ripping the video only, audio only, recombining, and re-encoding.

My grad school program starts back up in about 3 weeks; any apparent regularity of updates may diminish then. Additional trailers will be posted in this post and notification of such will be made in the form of a thread "bump." If other people post movie trailers and they meet or exceed my quality standards then I will add them to this post.

Re: Movie Trailers
 

Added Toy Story 3 - Note the first ~36 seconds of the trailer is intended to be lower res home video footage.

Re: Movie Trailers
 

The Dark Knight Trailer 2

Multichannel audio is now correctly mixed and there is no clipping in audio. But I´m not quite sure about video. It looks like it´s sometimes a bit jerky. So If you have time just check this out.

Re: Movie Trailers
 

Added Zombie Land

Re: Movie Trailers
 

Slender - you may want to up your bitrate slightly in the future.

Re: Movie Trailers
 

Added:
Edge Of Darkness
Star Trek
Slender's Dark Knight

Re: Movie Trailers
 

Maybe, perhaps, yes, no. I´m just now experiencing some performance problems with lower avg bitrates, but full screen resolution. It´s not all about avg bitrate. Just looking different files with bitrate viewer and thinking that what is n900s max VBV and vbv buffer size. For example in dark knight there is quite much blackness so bitrate doesnt go up so frequently. We need some stress test file.

Dark knight has lower avg bitrate but its peaks are higher than ironmans.

Re: Movie Trailers
 

You might consider using HandBrake for doing your encodings, it's much simpler, there is no need or reason to to multiple steps (demux audio/video, encode the streams, remux, etc) as HandBrake does all of that in a single go. Select the source, select the target format, change options for specific resolution, audio/video bitrate, etc, then encode to h.264 (using x264) in an .mp4 container without another thought.

It's got versions for Windows (32 bit), Linux (32 and 64 bit), and OSX (32 and 64 bit) so, it's not like you can't run it. :)

I use it for encoding pretty much anything as the internal libs now can decode almost any source material without any additional materials or codecs needed. It's as close to a one-step encoder with the best possible results you're going to find.

And realistically, if you encode to 400 pixels wide, the videos will still look fantastic and you can save a ton of space in the resulting file - the N900 will simply double-up to play it full screen and realistically nobody will be hard pressed to notice the difference.

I still have a Dell Axim X51v that I've had for years now, and I use HandBrake to encode content to it in a variety of forms, including AVI as well as MKV containers - the Intel 2700G GPU in it handles the playback and offloads that from the CPU so it's still more efficient at playback than most any handheld device ever made. 5 years after it's introduction, it is still just as useful today as it was on day 1... actually, a lot more useful since I have Windows Mobile 6.5 running on it without issues. :D

For all the N900 offers, it's sad that it still basically sucks for actual hardware-based decoding of video content such as these clips. Sad, really, since nobody out there in the "Smartphone" field seems to get it yet. In time we'll see devices with far longer battery life and better/larger screens, but all we can do right now is get by.

Hope this helps...

Re: Movie Trailers
 

I use handbrake (video, yamb output), yamb (joining of audio+video), and either quicktime pro or tmpg for audio.
Second, handbrake is not a one-stop solution for quicktime movie trailers to n900. Try it, you will fail.

The n900 does not suck at hardware based decoding. These clips play perfectly.


The point of me encoding these movie trailers in this fashion is to show off the beautiful screen (both in color and resolution). I am not posting any other videos, such as movies or tv shows, because of legal concerns.

Your "help" was not helpful and not appreciated.

Re: Movie Trailers
 

bbz_Ghost,
I think that this is really nice way to test N900 limits. Actually nobody knows what the exact limits are and right now there is some people just guessing what optimal values could be. With video+audio its complex when you have to take account boths bitrate, diffrent settings and additionally optimal buffer size limit which I´m right now trying to find.

I know that i could make almost half resolution movie and probably wouldn´t notice difference, but that's just not the point :) Handbrake is quite good, but i really want to know what x264 settings mean and as Clayton said handbrake can't handle everything.

If someone knows N900 optimal VBV settings please let me know.

Re: Movie Trailers
 

I grab HD QuickTime trailers directly from Apple's website using a combination of addons with Firefox and Greasemonkey, then feed them directly into HandBrake without issues, and convert them to the final format so, I don't know what steps you're either missing or just not getting. Doesn't require all that multiple demux/remux action.

In my experience of using HandBrake since it's inception, and with the latest versions and snapshots, the only file content it can't natively accept as source material is/are Real Media clips which, well, who cares about it anyway. ;)

Maybe the fact that I run Windows 7 could play into all this since the native format decoder in this OS covers everything out there save for Real Media - I can even play back those very same QuickTime trailers downloaded from Apple using one application - Media Player Classic Home Cinema - and nothing else but Windows 7's own internal decoders.

Regardless, I don't see a point in encoding videos to 800 pixels wide when none of the current video standards use that format natively to begin with. Encoding to 400 pixels wide and letting the device upscale is still going to garner you an outstanding image that's far more than adequate - and I've owned several N770s, 3 N800s, and one N810 in the recent past so I've done hundreds of encodings for those devices. I am quite familiar with the 800x480 working resolution of Nokia ITT devices.

But whatever... the info is there for anyone to read, as no one has the "end all be all" perfect profile for any device. Every piece of content is different and should be encoded accordingly.

As I said before, the Axim X51v has been handling video decoding with the Intel 2700G for 5+ years now, without issues. I guess it's about time other device manufacturers finally catch up...

Re: Movie Trailers
 

I grabbed some 1080p trailers with 6 channel audio from Apple's website and couldn't transcode it properly with current stable version of handbrake. Sound was clipping/distorted on explosions and downmixed wrong way. First didn't notice but looking and listening encoded file over and over again you start to see and hear things you want to make better. It's just makes me happy to tinker stuff with avidemux2 :) Made resize to 800 wide resolution using Bilinear conversion. I would like to use Lanzcos3 but some reason it gives subtle horizontal gray lines to background. After that msharpen to sharpen things up. Audio I extracted and downmixed with mplayer which has extra codecs. It´s just same thing with ffdshow or with avisynth. Experiment and have fun.

Reading and learning from doom9 or nowadays doom10 is just fun. There is people who do not want compromises.

Re: Movie Trailers
 

'Your "help" was not helpful and not appreciated.'

Haha, check you out! Got your knick knacks in a twist then.

Anyway, your approach seems rather long winded and massively unnecessary.

I encoded a 1080p Up trailer in handbrake, using the preset described on the encoding wiki, and it looks, and sounds, absolutely unbelievable. HD quality, better then the included 9 trailer. Showed to some customers today and they were blown away.

Handbrake is a very good tool for easy encoding. because its easy, don't be fooled into thinking it doesn't give you as good results as all the fannying around you did with vid and audio.

And, as usual, a screen that small can only show so much detail. Any standard AVI can 'pop' on that little screen. An episode of Lost, with the vibrant greens and blues, can look breathtaking, even as a 'standard' file.

Re: Movie Trailers
 

Luke Valentine,
If you answered to me then I do not know if we speak same language and i encourage you to read my text again, but if you didn't then ignore this.

Re: Movie Trailers
 

Nope, not to you mate, the original poster on page 1 got a little snappy.

And then I just commented on the quality that I seem to be able to get through the recommended handbrake preset on the wiki.

On a side note, regarding your encoding -

Can you remember what settings you were encoding using? Did you click 'Web optimised' on the first page? It seems to make a big difference. And the N900 doesn't seem to support anamorphic, so hopefully you either set that to NO or CUSTOM. Handbrake seems very good, once you have found the right settings.

Re: Movie Trailers
 

When ripping audio and video separately and remixing you can get better quality video and audio files.. and often smaller.. than with using Handbrake. Handbrake is not the end all be all solution of audio and video encoding.. there is still a place for manual conversions and that's getting the absolute best possible rip you can. Whether it's worth it or not is the question as it's much more difficult.

On the N900's screen could the human eye tell the difference between a completely 100% optimized (not that I'm sure anyone's achieved yet) video file and a good looking handbrake video? Probably not. But some people are perfectionist, they like having complete control of their rips and settings. This isn't something to yell at someone for.

OTOH: the "not helpful and not appreciated" comment was definitely not warranted, I don't think.

Re: Movie Trailers
 

Luke Valentine,
I have tried wikis baseline3.0 preset. I´m now comparing different files with bitrate viewer:
http://www.winhoros.de/docs/bitrate-viewer/index.html
I do not know if it shows things properly, but right now I´m having problem with 30fps file which looks like it´s avg bitrate is lower than what I have encoded before/these trailers here but it´s still jerky. And yep..I noticed that you have set resolution and hit keep aspect ratio for that preset I´m not that Noob :)

Re: Movie Trailers
 

No ones yelled.

The OP was out of line with that comment though. And by now, people have proved that for regular HD files, handbrake will give you a stella out put.

As regards file size, well im not sure what some people are looking for here. if you want the quality, the size is a secondary matter, surely. Straining a file through several encoders may make you feel like your doing something magical, if you lop 50mb off or so, but for what purpose? The memory of the device is huge, utilise it if the quality dictates.

In my eyes, no rip the Op has done has come close to the few I have done myself, both at 900mb, both done in handbrake.

As you correctly pointed out, a human eye can only see so much, on such a small screen. I think what bbz_Ghost is trying to point out is to keep that in mind when encoding for the device. It only has so many pixels.

Re: Movie Trailers
 

Ha, no offense implied!

The files that you are encoding, are 720 or 1080? I've found that encoding at 30 FPS really slows some bits down.

Re: Movie Trailers
 

If I´m going to encode movie/show just for myself then probably i wouldn't care much about quality and settings. For sure 400 wide is probably just enough when we are speaking about moving pictures. For me this is just experimenting and trying to find optimized values for different sources. Fun :)

Re: Movie Trailers
 

720p30. But i think that it doesn't matter what fps rate you have because bitrate comparison is universal between files regardless fps.

Tried handbrake and it made quite low bitrate file. Hmm, have to investigate.

Re: Movie Trailers
 

Well, all the best with it! You seem to know exactly what your doing anyway, I think i'll just settle for videos that play smooth, leave the expertise to the guys who know what they're doing, haha

Re: Movie Trailers
 

These trailers are great - and are encoded exactly for the great N900 screen - 800 wide.

I can easily tell the difference between videos encoded at full and half resolution (400 wide).

One of the important advantages of the N900 is its ability to play very high quality videos on a high-resolution screen (so there iPods), and it uses hardware acceleration.

Re: Movie Trailers
 

It would be a pretty quick and painless process to convert anything from the apple site to N900 format. I can do a batch process and cook out like 20+ super high quality trailers while I go eat a sandwich.

thing is who really puts these on there device? I watch a movie trailer one time to see if I like a movie and only because I want to check if I like it or not, I dont tote it around to view multiple times for no reason.

Well downloading your Ironman 2 trailer now to see what it looks like and what kind of codec settings you used.

I agree on using 800px wide if you want max quality, its the native for the N900 screen. No need for 30fps though, cinima is not run @ 30fps and recoding an original source that is only 24fps to 30fps is rather barbaric and pointless, infact you may lose quality there since your not going to create any new frames just by increasing the frame rate and the interpolation between the frames could get jarred up. Even in a best case you just keep the same quality but made it harder to render and the file size larger.

I assume you just used baseline 3.0 H264 profile? or have you found the N900 can handle some of the more advanced features of the codec?

Re: Movie Trailers
 

I get no sound on the Avatar trailer, all the others ones will say completed download after about 700k

Re: Movie Trailers
 

Just downloaded Avatar and works here. Do you get sound on your Laptop? Have you got latest extra codecs installed?

Re: Movie Trailers
 

I didnt try it on my laptop I just put it straight on my phone

I do have the latest extra codecs installed, but I cant play mpg or mkv's either as they say unsupported

I think I will uninstall the codecs and re-install them as ive upgraded the FW since installing the codecs

Re: Movie Trailers
 

The codecs were refreshed especially for PR1.1

Re: Movie Trailers
 

Here is one for you guys, I'll do some more soon if I can find any more good trailers that have not been posted already.

Re: Movie Trailers
 

Thanks, I get sound on avatar now but I still cant play mkv's

Re: Movie Trailers
 

Not sure if its MKV per se or the encoding of the vid. Bug in PR1.1 cant play files with chapter markings. Have you tried to re-mux using avidemux. V quick so is pretty painless.

Re: Movie Trailers
 

I havent tried anything other than a couple of different mkv's not even sure if they have chapter markings in them

Media player just says it cannot play that format, its no biggie though

Re: Movie Trailers
 

If your encoding something for the masses you should be doing it in a manner that it works with the device out of the box. A format that is supported and a codec that is supported.

In other words these should be in a .MP4 container encoded with .H264 & .AAC

Let me know what trailers are not encoded that way that were already posted and I can redo them so they play properly without you needing to take a risk installing the extra codecs package, I dont have it on my device I have read a few too many post about issues caused by it.

Re: Movie Trailers
 

So do it. Search here and wiki and be amazed how difficult its to some people even install some program to pc and try to find out what settings they should put there.


That´s nice. Do I care about your habits? Nope.

Hmm. Have to check that out, but I do not remember that he encoded it 30fps. And this threads point is to find and demonstrate maximum quality. If you wan optimum size&quality then there is threads and wiki for that.

Search here and wiki.

I did following with dark knight
-> Demux audio to wav with mplayer (binary codecs included)
--> careful here because we have to downmix 5.1 or 6.1 proprely to stereo. Have to listen carefully wav because explosions might clip.
-> Open video and external audio in avidemux 2
-> Resize with msharpen
-> Unsharpen mask to sharpen picture (because of resize)
H.264 settings from wiki.
->made mp4 file
--> goto start if result doesnt satisfy

Unfortunately i have found that kmplayer plays video files smoothly when default media player sometimes gets jerky. I do not know why because both use same engine but there is bug report already about this issue.

.edit
Ironman2 and dark knight and couple of other trailers have worked for me from first firmware trought both firmwares. I have not yet tested avatar

Re: Movie Trailers
 

no need to worry about audio slender, just demux and remux the original. Remember AAC is a lossy format, so it already lost some of its original data and quality. If you transcode from lossy to lossless (AAC to WAV) you only increased the file size and then when you code that again to a lossy codec your going to lower the quality even more than it was originally.

Since all the Apple trailers are just using AAC LC at an acceptable bitrate its going to play on the N900 as is without any transcoding or additional loss of quality.

I have no problems contributing to your little thread, but your attitude is way off base, this stuff is not hard so no need to toot your own horn for knowing how to do it and infact you still have a lot to learn.

Re: Movie Trailers
 

*facepalm*
I have found SOME trailers with 5.1 or 6.1 sound and downmxing is broken with current handbrake. Search doom9 for downmixing and normalizing audio.

.edit
About attitude. You just said that you do not understand why someone would watch trailer from small screen again and again. Excuse me but how about if you chek your attitude first.

Re: Movie Trailers
 

I stated that I dont know why somebody would put a trailer on there phone, a simple statement and not directed at anybody. You can drop your childish he said she said drama act now and move on and make this a worth while thread. If you need to take it further send a private message.

You started the situation upon yourself by coming in here claiming the title of encoding god when really your just another normal user and reliant on the real experts to make a GUI for you.

So from your original post being the "quality control freak" you should know basic things like each time you encode a lossy format that you lose quality and since you have these "standards" you wouldnt be doing that.

Why do I need to know downmixing is broken with Handbrake? I dont use it. I compile my own custom x264 binary for 64bit encoding its 20% faster than the x86 binaries you can download and I run all the other tools directly from the command line so I can keep the leading edge on all the binaries with any dependency on a GUI.

MP4Box.exe
NeroAACEnc.exe
x264.exe
avisynth
Mkvmerge.exe

Thats most of what I use, hardly ever do I need something else.

I like GUI's its a great way to start and to learn, but once you get past that you start to do things yourself and learn a lot more.

Edit: Slender I thought you were the OP :D had you two mixed up. I cant load anything on this forum right now its moving slower than free dial up service from my sega dreamcast 8 years ago.

I felt the OP had a really bad attitude, and then you kinda jumped into the same game. We can collaborate and learn from one another the goal of a forum like this, or we can go at each other throats and I never start the attack but I am always willing to counter attack like I just did at you.

Re: Movie Trailers
 

Well fact is that generalizations do hit somebody eventought you try to not direct them to specifically to anybody.

I´m far away any encoding god. I´m just trying to say that things are not easy as you might think. Firstly there is different kinds of trailers on apples site. They are not all encoded with same profile.

Hmm. Only reason I´have messed with some trailers audio was that:
- Just copying aac didnt work
- Trancoding aac to aac with handbrake broken downmixing (speak was coming from left channel only)
- demuxed with mplayer but noticed that explosions were clipping/distorted ( noticed only when listen on high volume)
- and after finding some Mplayers settings about downmixing i found that downmixer seems to use correct algorithm when combaining all surround channels and there was no clipping.

Useful tools. So we can iterate optimal settings here.

This is true. No hard feelings but posts before you where some people also said that they do not understand and wondered why would someone encode with highest quality already made me little pissed.

Hmmm. And i´m quite sure that hydrogenaudio forum has some other toughts about aac goodness. But transcoding is generally bad that i agree.
