How can I play ABSOLUTELY LOSSLESS video on the iPad2?

Hi everyone!
I'm creating some test videos for a project I'm working on. I have a sequence of png test images that are 1024x768. I would like to have these images play back on the iPad2 as a video. The catch is that there needs to be absolutely zero mathematical loss in the final video - each frame should be an exact representation of the associated png image. This is not an aesthetic requirement, it's a scientific requirement. I'm doing a study on pixels. Any suggestions?
I've been using the free version of FileApp to load videos onto the iPad and play them through that app. I've been encoding my lossless video into Quicktime in AfterEffects using a variety of codecs, including Animation and PNG, both of which playback on my PC perfectly lossless-ey, but when I try to play them back on the iPad2 they don't play back at all. Some other codecs like the H264 or Jpeg get very close, but there are losses in the final version.
I'm not concerned with file size... I have the 64Gb version and I'm willing to use all of that for this project.
Any suggestions for video playback apps? Preferably free so I can test this lossless requirement without wasting some money first.
Any suggestions for encoders and codec settings?

Well, if you are not concerned about file size, then you can just encode the videos as APNG and then play the videos with https://itunes.apple.com/us/app/apng/id447928057. All you need to do is put the xyz.apng file on a webserver somewhere and then copy and paste the URL into the bar at the top of the APNG app. The file will then be downloaded and played. Just be aware that a full screen iPad size video is massive and it will tax the IO subsystem to the limit, so the max framerate you will be able to get on an iPad2 will be about 20FPS. In case this was not clear, APNG is basically the same as a series of PNG images, it is completely lossless.

How can i delete or clear video from the youtube most viewed?

How can I delete or clear video from the youtube of "most viewed?"

The 'most viewed' can't be edited - it is the videos on YouTube that have been watched most, so apart from the video being taken down from YouTube, or other videos getting more viewings, they will remain in that list.

How can I play multiple music videos continuously on Apple TV?

Regular music plays continuously, one song to another, etc. I can't get my music videos to do the same. One plays, and after it's over, ATV won't go to the next video. I can't figure it out. Does anyone out there know how to do it?

What I find is really silly, is the fact the music video's are listed under that artists albums in the Music menu. And when you go into the video 'album' (called 'Unknown' unless you change it) there is an option to shuffle the tracks. Clicking this just results in an error message. So, they should either remove that option if it is a video album, or, better yet, GET IT TO WORK. So silly of them to omit this.
I have submitted feedback.

How can I play iPhone 4 video on my HD TV

I just took some video on my just arrived iPone 4. I plugged the USB end of the iPhone 4's cable into my TV. I scrolled through 'Inputs' on the TV. No go using 'Camcorder' setting which I connect to the front of the TV when used. No go using 'PC' input setting either.
I am not positive I have actually used the USB connector to display camcorder video or camera pictures in the past, but I 'think' I have.
SHould it work with just the iPhone 4 supplied cable?

No easy way to do it like on the EVO or droid X which both have HDMI mini out for that exact same purpose. Apple wants you to buy their overpriced cables instead and then only display it in 480p max. YAY thanks apple for taking 2 steps backwards. I think apple just adopted the HDMI format for the mac mini but before it was nothing but the old OUTDATED DVI connection, lame. Try this link below. If it works for 3gs it should work for your iP4.

I know there is an app called QIK video pro that will record videos and let you stream them over your wireless network.
If you have a pc and a ps3 you can download the videos you took on your iphone to your pc and stream them to your ps3 using a free program called tversity or just put the avi files on a thumbdrive and plug and play via your ps3 or the usb input on your tv as long as its in a format your pc can handle and display. Confusing yet?

How can I play music and video files in Solaris 10?

Hi all. I just downloaded Solaris 10 and installed it. I haven't used it for a long time (since version 8), and as I can see now, there are many improvements. I just loved Java Desktop! :)
Can someone please tell me what libs or codecs etc, do I have to download and install in order to play music and videos (mp3, wmv, dvd etc), and where I can find them?
I use the on-boaad sound system (Realtek AC97)
Thank you all.

You didn't mention if the sound drivers are working. If not, download and install the driver from here and reboot (it supports your codec):

DVDs are more of a problem because of DCIMA. Look around.

How can I control a FLV video using the main play bar (not the FLV skin)?

I need to have the ability to play/pause an FLV video in a slide with the main play bar. Research has shown me that in previous versions, there was a "synchronize with project" checkbox that enabled this. I cannot find this in version 8. Is there a different way of doing this?

Hello ,
Welcome to Adobe Forums
Try inserting the video as Multi-Slide Synchronized Video instead of Event Video ,
Then down below there will be an option to Distribute the video across the slides and you can select from Slide n to n ,(Where n is your slide number).
Hope this will serve your need.

How can I watch 1920x1080 60p video in the iPad?

Background - I recently purchased a Sony Camcorder. It records in AVCHD format 1920x1080 60p. I have converted the AVCHD format to .mov using clip wrap but I cannot sync the file to my iPad 3 with iTunes probably because the iPad can only play up to 30 fps and this video is in 60 fps. I can record in a lower quality mode of 1440x1080 30 fps but the quality is significantly less. Is there a way to make this compatible somehow to play on the iPad? Maybe convert it from 60 fps to 30? I know there must be a way. I have a 3rd party app called Filebrowser and when I play the .mov 1920x1080 60p file directly from the source (my MacBook) it plays it on the iPad and the quality is incredible. Only problem is that since it is streaming the iPad can't stream fast enough to play it without pausing every 5 seconds. If my camera could record in 1920x1080 30p I wouldn't have this issue but for some reason Sony doesn't allow this. I chose Sony because the video is significantly better than Canon, Nikon and other brands. Does someone please have a suggestion? I have been researching for hours so if there is another forum post that explains I am sorry I could not find it and I have a migraine from searching. I am definitely an amateur at best trying to get great quality home video on my retina display iPad. What good does the retina display do if I have to watch mediocre video quality. Any help is appreciated. Regards.

Hi,
I too would like to know the answer to your question. I don't thnk the answer you got was what you were looking for. I would go to the Digital Vdeo Infrmation Network forums and ask there about which is the best software to convert 60p to 30p. I don't remember off hand how exactly to do it. But it is a little complecated as I recall. People over there will be more than helpful.
I took 720p 60fps footage when I should have taken 30p footage with my Canon 60D camera.
I just hope that in the next IOS6 update that we will be able to import 60d footage. But I am not holding my breath.
I can't see why 60D footage would not be possible on the ipad3. It is the same amount of data bits. 1280x720 60p vs 1920x1080 30p.

How can I play an audio file without the whole screen going black?

When I play the mp3 file on IE it opens in a small screen so I can still see the web page.
On Firefox the whole screen is taken up with the sound file being played.
Can this be changed?

Is that file played in a tab in the current window or in a separate pop-up window?
Are you allowing pop-up to modify the window size (dom.disable_window_move_resize = false)?

How can I play a playlist and not the entire library on my shuffle?

I can't seem to organize songs into playlists and then play only the songs in the playlist -

There is if you play music from your computer (mine is connected via AirTunes to several stereo systems) or if you later get a Nano, or iPod with Video or an iPhone that does support playlists.
You can also use them to load songs on your Shuffle. For example, say you are going on a long exercise walk and you want many motivational songs with increasingly faster tempos. You could create a playlist on your computer, put the songs in it that you want, in the order you want, call it Long Walk, and then when your Shuffle is connected choose to Autofill from the playlist Long Walk

How can you create a karaoke video with the music lyrics?

I'm working on a generic music video. I want to add written lyrics to the video so that people watching can follow along with the singing. What is the best way to create trailing lyric highlights to the way the song is sung?

QuickTime Player Pro ($30) and lots of patience.
QuickTime Player supports "text" tracks and, with some special manipulation, can display the text "karaoke" style.
QuickTime Player 7.6.6 (not the X version) can play ".kar" files. Millions of them found on the Web and easy to download. They include MIDI audio (computer generated sound) and are very tiny in file size.

I downloaded a .kar file using QuickTime Player Pro and the Movie Properties window, extracted the text track and then changed the text using TextEdit. I then added my new text track and deleted the original.
