This is a question regarding video files and my iPad 2, currently running iOS 6. While I am a very experienced PC user & builder, I'm only "average" when it comes to my iPad 2. In my PC activities, it is my observation that when I run VLC, which is my all purpose video player, the video will fill the screen, limited only by whether the vertical or horizontal dimension reaches the screen edges first, so I get to use most of the available screen pixels for the video image. The image will never be cropped, so there may be unused pixels depending upon the aspect ratio of the video image, compared to the screen's aspect ratio. I have a large number of video files loaded into my iPad 2. I use GoodReader for my file management. I have one folder which contains a bunch of video tutorials for Photoshop CS5, in either a MOV or MP4 format. Most of these seem to run just fine, although I think I did have a couple of the MP4 files hiccup. These files were not created by me, but downloaded from several online sites. And when they are run, they too will fill the screen as in my PC. I have a lot of WMV files (slide shows that were used to create a WMV file) that were created by me on my PC. When I run them using VLC on my PC, they will also fill the screen, until either the V or H dimension reaches the monitor's edges. So I have pretty much a full screen view of these videos I wanted to load these onto my iPad 2, but WMV files will not play there. So I used the free program "Any Video Converter" (AVC) and converted copies of these files to MP4, which the iPad handles nicely. These converted have an MP4 filename extension, and I chose the MP4 type which was listed for iPad 2. The converted filename has some other characters in it. A typical file name is Video22_x264.mp4, where the original filename for the wmv file was Video22.wmv. In the conversion process, AVC offers a variety of choices for the iPad. I chose the mp4 for the iPad 2. The conversion process applied the new file name, and added in the "_X264". But this converted file now will no longer try to fill the screen on my PC, and also uses much less screen space than is available. And on the iPad 2, the image is of course razor sharp, but far from full screen. Trying to use my fingers to enlarge the displayed image does nothing here. Somehow this converted mp4 has lost all ability to do any pixel doubling or the like, and is just displaying pixel for pixel to produce whatever size that will be. But the MP4 files that I've downloaded off the Internet are still perfectly capable of "stretching" themselves to fill the max screen area without distorting the aspect ratio. As I noted, other "plain" MP4 files can this just fine on my PC, and iPad 2. So it would seem that the "_X264" is indicating a special type of MP4 which cannot enlarge itself to fill a screen. So the real question is - Is there anyway to convert my WMV files to an MP4 file which will have the capability to expand itself on my iPad 2 to give me larger screen image?
