Video format/encoding in Apps

Hello,
i try to build a video learning app. And this will be my first app with the media framework, so i'm not familar with that stuff.
The iOS devices has many different screen resolutions and i wanna have the best result on each device.
So i have to find out:
- which video codec i should use.
- should i deliver video files for each resolution? i think there are 4 diffrent resolutions
- is is better to deliver a special app for the iPad because the video files are much bigger?
I have so many questions an try to find out which is the best way to do the job.
I know that this is not much input but i'm at the beginning and looking for best practice scenarios. I hope my english is not so bad that you cant understand what i need.

You should use H.264 for the codec. It's probably the most standard codec you'll find in Apple systems and beyond.
About the resolutions, you'll probably don't need to care much about that. As long as you have a decent resolution, your video should scale well on any device. But, if you really want the best resolution for each device you should look at Apple specs for each device.
For instance, the iPhone 3GS supports 480p, while the iPhone 4 supports 720p, and the iPhone 4S goes up to 1080p. Both iPads should support 1080p.

What video format to export for Ipad Apps

Hi,
I am new in export flash to ipad. I tried to export my video as FLV for my ipad apps, it plays but its lagging or jerky.
I had tried other formats like mp4, f4v, m4v or mov it just doesn't play
Wonder if anyone knows what video format to export for my ipad apps?

[email protected], on an iPad, here's what I did to get the FLV loading and taking up (most) of the screen. You can't use the FLV Component skins so you have to use the UI Components as markc888 suggested below your comment. My only gripe with this solution is that I can't get the fullScreen button to make the video go full screen.
This is starts from a playVideo button on my stage.
playVideo.addEventListener(MouseEvent.CLICK, playVideoClick);
function playVideoClick(event:MouseEvent):void {
var flvPlayback:FLVPlayback = new FLVPlayback();
flvPlayback.x = 62;
flvPlayback.y = 62;
flvPlayback.width = 900;
flvPlayback.height = 506;
flvPlayback.fullScreenTakeOver = true;
flvPlayback.autoPlay = true;
flvPlayback.source = "yourMovie.flv";
flvPlayback.bufferTime = .1;
addChild(flvPlayback);
flvPlayback.playPauseButton = playPauseBtn_mc;
flvPlayback.stopButton = stopBtn_mc;
flvPlayback.seekBar = seekBar_mc;
var closeMovie:yourMovieClip = new yourMovieClip();
addChild(closeMovie);
closeMovie.x = 977;
closeMovie.y = 77;
closeMovie.addEventListener(MouseEvent.CLICK, closeMovieClick);
function closeMovie(event:MouseEvent):void {
flvPlayback.stop();
removeChild(flvPlayback);
removeChild(closePres);
Hope it helps...

How do I get Pro Video Formats 2.0.1 to stop appearing in Mac App Store after I've installed it?

Pro Video Formats 2.0.1 appeared in my App Store a few weeks back (I'm running an 2011 MBP with 10.10.4 and have been using the betas). I installed it, and it continues to appear as an update every day. No matter how many times I install it, it continually comes back. I even wiped out all of my codecs in /Library/Quicktime, reinstalled the PVF. I downloaded the standalone installer, ran that. No change. I've seen a few mentions of this online, but hoping for a fix!

Best video format to encode for playback on iBook G4 1.2GHz?

I have been scratching my head for a week on this. What is the best video format that is highest quality and will playback smoothly on my iBook g4 and my iPhone 4? It has 1.25GB of RAM and I upgraded the HD to a WD 250GB 5400 RPM IDE drive 2 years ago and it's running dual boot Leopard 10.5.8 and Tiger 10.4.11 (keeping Tiger for Classic Mode).
I have a very large HD video collection consisting of 720p HD DVDs and 1080p Bluray discs that I have already spent a year to convert to MKV and MP4 files for storage on my media server. They have all been ripped and encoded with H264 using Handbrake. The average 720p movie is about 4.5GB and the average 1080p movies run about 8GB. I have over 100 movies stored on my media server and they playback fine on all my computers. They work fine on all my Windows 7 systems, they even play fine on my G5 2.0GHz DC late 2005 Powermac with 8.5GB Ram and the NVidia 7800GT.
Most of my 720p files can be reduced in size and or quality to 1-2GB and are playable on my iPhone 4, iPad 2 and even my little Acer Aspire One netbook in m4v or mp4 format.
I know my iBook is out of date, but no matter what compression method I have tried, the only thing it can play is MPEG-2 encoded media. And it cannot handle any h264 video I make, even at 480p settings using the simple profile. Since MPEG-2 takes 4-8GB per movie, this is a huge waste of HD space. And if I encode my movies like the old iPod video size, it looks like crap in full screen. I really want to store about 20 movies on this iBook for playback when I travel since I have 2 extra batteries. I need to movies to playback on the iBook and be able to transfer them to my iPhone 4 or iPad at any time.
Is there any method for getting 480p to encode and playback well on this iBook without making it look like crap or using the old DivX avi standard? If I have to reduce all my movies for playback on the iBook, I don't want to go lower than 480p because I want the same conversions to work on my iPhone 4 as well with decent quality. It is redundant to keep making copies of each movie for each device. Anyone have any suggestions? I don't want to take my little netbook around with me because the screen is too small and there is no opticle drive.
If anyone has any ideas, please post which Handbrake profile or other that can work... or let me know if my iBook is just garbage now. Thanks!

I am not asking you how to rip a DVD. I am asking how to convert any video file for decent playback on my iBook or iPhone!
This feature is available in iTunes so you can convert your DVDs to iPod playable formats. But when iTunes or Handbrake (or even Apple Compressor) convert anything, even my own videos made with Final Cut and iMovie, they will play on any iDevice other than my iBook unless I use the lowest most terrible video format.
I am just trying to figure out the proper video format the iBook can play. I am not ripping the DVD's right now... did that years ago anyways (and half of the videos I want to convert I made with iMovie during my travels in China and Hong Kong... I am just trying to play movies I already own on an older iDevice... my iBook. Converting purchased videos and home made videos is in no way illegal.
You misunderstand what I am asking. I am not trying to break digital copyright. If this is breaking digital copyright, then why does iTunes allow me to convert the movies for my iPhone 4 in the first place? You are telling me if I didn't purchase the movie from Apple I cannot watch it on my iPhone and iBook? That is not right.
I just want to know what the proper video playback requirements are for the iBook hardware. Plain and simple. If it is illegal in any way to tell me how to do it, just tell me what video my iBook supports. Apple tells me what video my iPhone supports ie. 1280x720p @ 29fps.... blah blah blah. Seems so far the iBook can only play a DVD MPEG-2 stream and no advanced codecs like h263 or h264. I just want to know what format the iBook can handle.
I have exported movies from iTunes and of my time in Hong Kong from iMovie and I cannot get them to play on the iBook at all if they are even 480p. So I just need to know what the max video playback is. If it can only play 320x240 or something, it is completely useless. I remember years ago when I bought the iBook, it did play the sample h263 and h264 videos that Apple had on their website (some of them 480p-720p)... but today it seems it can't play anything but 320x240 or less without getting locked up. I know the HD video requirements are G5 or higher... but we are talking DVD size cannot play in h264 mp4 formats, only MPEG-2 formats. This makes no sense? So I need to know the exact maximum resolution, framerate and codec this iBook 1.2 GHz can handle.
Don't tell my watching movies on my iBook, even the ones I made is illegal.

Best video and audio converter that contains most format at mac app store

Dear All;
What is the best video and audio converter that contains most format at mac app store?Can you suggest any on Mac App Store?
Regards;

I use Wondreshare's dvd ripper. I travel for a living, so the $60 or $70 I spent to rip my entire dvd collection onto an external hard drive that I can take anywhere I go. Their software isn't available in the App Store to my knowledge but I have had it for a couple years now without any trouble.

Hello, I'm wondering if any of you know whether or not there's an App that allows you to watch multiple video formats online (like online TV series, movies etc) Thank you so much

Trial and error.
I wish I had a better answer for you, but that pretty much encapsulates it. There is some, but not much, good wisdom out there, but it takes a significant amount of experience to be able to recognize it. The software development community if currently afflicted with a case of copy-and-paste-itis. And the prognosis is poor.
The solution is to be brutal to yourself and others. Focus on what you need and ignore everything else. Remember that other people have their own needs and methods and they might not be applicable to you. Apple, for example, can hire thousands of programmers, set them to coding for six months, pick the best results, and have the end-users spend their own time and monety to test it. If you don't have Apple's resources and power, think twice about adopting Apple's approach. And I am talking from a macro to a micro perspective. Apple's sample and boilerplate code is just junk. Don't assume you can't do better. You can.
Unfortunately, all this takes time and practice. You can read popular books, but never assume that anyone knows more than you do. Maybe they do and maybe they don't. It takes time to figure that out. Just do your best, ignore the naysayers, and doubt other people even more than you doubt yourself.

Adobe Media Encoder CS4 H.264 iPod video format green flashes in Quicktime

Quicktime 7.3.1 apparently shows no flashes but 7.4.5, 7.5.5 and 7.6 all show green flashes on videos encoded in AME CS4 H.264 iPod video small.
No other quicktime versions tested.
Videos play fine in VLC Player and Adobe Media Player.
Videos encoded with the latest MediaCoder sourceforge application play fine in Quicktime.
Clearly something's wrong with the way Adobe exports and the way quicktime 7.3+ reads H.264 videos.

I think it may be the QuickTime Player issue and not Adobe Media Encoder. Its seems to play find in other players like Adobe Media Player and Windows Media Player after installing Windows Essentials Media Codec Pack 2.2c. (http://download.cnet.com/Windows-Essentials-Media-Codec-Pack/3000-2140_4-1066270 9.html). Haven't check to see if it plays correctly on my i-Touch. Not all videos I encode from .AVI to .MP4 using the i-Pod small preset seem to have this issue.

I finished making an animated .gif image in FireWorks. My question is, how do I convert it into video so that when I edit video, that every video editing program recognizes it? Long story short, How do I convert animated .gif files into video formats?

I worked in Adobe FireWorks to make the animated .gif. What program do I use to convert the file from .gif to any video format: .mp4, .m4v, .avi, .wmv, etc. I want to convert it into video format, so that QuickTime Player plays the video, I can insert it into iMovie '11 and edit, and also insert it into Final Cut Pro X and edit video.

Thanks for getting back with me so promptly. It has taken me this time to connect with the proper people to find out the information you requested.
The camera used to film the class was a Panasonic AG-HMC40P, owned by a local cable TV station; they use Kodak video encoding software, and a SD card was used to store the video. The file extension is .mts, and the mime file is MPEG 2 transport. He said I probably need an AVCHD converter, and the Mac app store lists 8 of those options, 4 free and 4 for up to $9.99. He said I'll also need a converter for later plans of posting on YouTube or on the website, and while some of those in the app store might work for the later needs, he knows one app called "Compressor" that would work for the uploading later. He also suggested I could try renaming the .mts file to .MP2T, but he wasn't sure that would work.
They don't work with Macs at the studio, but I had thought I could have some lessons there in editing, and apply what I learned to my iMac and iMovie.
First, though, I have to be able to see it and review it!
Thanks again!

Best video format for sharing with windows users

I've tried many ways to share videos with different clients, they mostly have windows computers (and windows media player I guess). I tried .mov (H.264) and mp4 (also H.264) from final cut pro X, but also from Compressor. I also did some test exporting Apple ProRes and then converting them with Mpeg streamclip, or even with Adobe Media encoder. Same problem, windows does not see these videos. I finally had to use a mov to wmv converter, but the final quality is really bad. Or upload the videos to vimeo, and then share the link (but I haven´t got a plus account, so I guess what I´m doing is not allowed, and i have only 500 mb per week). I believe that windows media player can be updated to open these phootage, but I cannot explain that to my clients.
Which would be the most compatible video format to share with clients?
Which paramaters should I take care of while exporting them?
Thanks!
Pablo

You should be able to export as H.264... I'm going to guess that your problem might not be the video -- it might be the audio. The audio track should be converted to AAC. Try exporting H.264 directly from FCPX. From Share > Export File (you might need to add that destination) > Settings > Video Codec > H.264 (audio should automatically change to AAC.) If you export as ProRes and transcode from another app, they might not be converting the audio for compatibility (LinearPCM/AIFF is not an "expected" audio format with h264/mp4, or even WMV, etc.)

Blocky video after encoding AVI

Hi there, I encoded an AVI of pretty good almost DVD quality, after encoding the AVI to a DVD using IDVD 6, the video is blocky around the edges....
Why is this? IDVD does not have any advanced features allowing you to play with the encoder settings so i don't what to do...
If I were to convert the AVI to MPEG2 using another application and then re-burn my DVD, would IDVD automatically skip the encoding process as I would be using a DVD MPEG2 format???
Anyone know of any other decent apps for making DVD's?
Thanks for the help, I truly appreciate it.

GIGO does not apply in this case
I bet it does...
the AVI was only 1hr 45min so it's not too long
...and what was the file size in MB? Note that if it were in DV video format, the file size would have been about 21 GB - I'll bet your AVI file was very highly compressed and no where near this file size.
What was the on-screen image size? Many AVI files I've seen use the old MPG-1 size of 320x240 pixels - just 1/4 the size of the image iDVD expects to see.
Maybe DVD studio pro is the answer i'm looking for!!
iDVD uses the same Compressor application that DVD SP does.

Video Format Total Solution: How to Convert and Edit Video on Windows/Mac

More and More video formats are coming out with different video encoders and it makes our spare time more and more colorful. However, it is not to say that there is no problems. Actually, different video formats make it difficult to share video with others, even your own camcorder and iPod. Is there an easy way to convert videos effectively. Yes, there is.
In this article, I will show you guys how to convert videos on windows and mac.
Part 1. How to Convert and Edit Videos on Windows
For Windows users, you need a Video Converter(http://www.aiseesoft.com/total-video-converter.html) to do that for you.
Here I use Aiseesoft Total Video Converter(http://www.aiseesoft.com/total-video-converter.html)
Step 1: Download and install Aiseesoft Total Video Converter
After you download it to your computer, double click it and it is really easy to install.

Step 2: Load Video
Click “Add File” to find the video that you want to convert and click “open”. It will be loaded automatically.
Step 3: Select the target to decode
In the “Profile” drop download list you can find your target according the usage of your output video, such as if you want to put the video on your iPod touch, you can select the “iPod” in the first list and “iPod touch 2 MPEG-4 640*480(*.mp4)” in the second list.
Step 4: Set Advanced Parameters
After you select the right output profile, you can click “setting” button to set your advanced parameters. You can adjust video and audio settings separately. In video section, you can change “video encoder”, “resolution”, “frame rate”, “video bitrate”In audio section, you can change “audio encoder”, “sample rate”, “channel”, “audio bitrate”If you want to save this profile and settings and use it next time you can click “save as” button to give a name to it. And the next time you want to use it you can find it in the profile list named “user defined”.
Step 5: Choose a Destination
To browse and find a output folder for your output files or just the default one.
Finally, Click “Convert” button to begin your conversion, here in the converting
interface you can choose “shut down the computer when conversion complete” or “open output folder when conversion complete” or you just do not choose neither one.
Tips: How to Edit the Output Video
This video converter is also a video editor, you can use it to edit your output video as follows:
http://www.aiseesoft.com/images/guide/total-video-converter/effect.jpg
1. Effect:
You are allowed to adjust the “Brightness”, “Contrast”, “Saturation” and you can choose the “deinterlacing” to make the video more enjoyable.
2. Trim:
In “Trim” section you can pick up any part of the video to convert.
There are two ways to select the part of the video you want. One is set the start and end time in the box. The other one is to drag the start and end button in the processing bar.
3. Crop:
This function allows you to choose a certain play area to convert. That means you can choose a part of the screen you like to convert. For example, you just like the tv in the middle of the screen, then you can drag the frame around the preview window to select the tv and the output preview will show you the output video.In this section you can also choose the “zoom mode”, such as “keep original”, “full screen”, “16:9”, “4:3”.
4. Watermark
In the section, you can add a watermark on the output video to show people something, such as your name, website, studio name or other things. The watermark could be words and picture. You can adjust the transparent of the watermark easily to make it more beautiful.
Part 2. How to Convert Video on Mac
This time you need a Video Converter for Mac(http://www.aiseesoft.com/video-converter-for-mac.html)
Step 1: Add File
Click “Add File” button to load the video you want to converter
http://www.aiseesoft.com/images/guide/mac-video-converter/steps.jpg
Step 2: Choose profile and adjust settings
You can find your output video format from a drop-list called “Profile”You can also adjust the specific settings of the output video, such as “Resolution”, “Bitrate”, “Encoder” and so on.

If you are OK with a DVD with a basic menu, you could try the Share>DVD option in FCP.
Good luck.

Best video format for mac and pc

Hello,
I recently embeded an mpeg video, flv, mp4, and swf video file to my web page. I then asked several pc users to go to my page and see if they could view the animation clips. They were were able to view all clips, but the mpeg and flv clips automatically downloaded to their computer. I don't want that to happen. The mp4 did not download, and it worked as well.
How do I stop this from happening? I ask becuase it seems flv is used by mac and pc users alike, and I think I may use said format.
What is the most widely used video format by both mac and pc users?
... should I just stick with mp4 since it worked without down loading?
rekh
code i used...

Colin has pointed you in the correct direction.
I'll bet you're using just plain text "links" to your files. That method by-passes the browser plug-in and can cause issues (especially on Windows).
You need solid html code that gives the browser plug-in all of the needed instructions.
Another thing that may have happened is that your fast start files have lost their fast start abilities. This happens with any fast start file that is then edited and uses a regular "save". Save As will restore the fast start feature (even in files that do not normally have it).
AVI is dead. Do not use it.
Many WMP formats (codecs) are not yet ported to the Mac OS so that delivery container should also be ruled out.
H.264 Video codec (default in most Tiger app exports) also requires the viewing machine (Mac or PC) have QuickTime version 7 installed.
Since not all machines can install QT version 7 (requires 10.3.9 or Win 2000 or XP) maybe you should rule it out, too.
So.
What are we left with?
Maybe QuickTime format using MPEG-4 Video codec and AAC audio?
They would only require QuickTime version 6 be installed. Since version 6 has been around for over 5 years it may be your best option.
But you're still going to get complaints from PC viewers.

I'm facing issues with using f4fpackager for different video formats.

I tried using the f4fpackager with flv files, but getting an error there too.
$ ./f4fpackager --input-file=sample.flv --bitrate=400 --output-path=flvsample
Error 14: Error when reading the FLV
Is there any particular video format specification which is recommended to be used with f4fpackager?

No the sample isn't same as FMS.
I'm able to fragment a video using another mp4 video. (Open source video downloaded from elephants dream site.)
But many others which I've tried, which are also mp4 videos, and which play well in flash player - are getting stuck. The generated f4m file segment I've already pasted above.
FLV files so far I've tried, are also not working. I get Error 14, Error when reading the FLV - So seems like again some format issue. I again can play this flv file directly from a flash player.
