New iPad (3): What's the real difference between 720p and 1080p, the two major high-resolution video formats?

image

In the MacRumors forums (thread HERE), an interesting discussion has emerged on the visible differences between the two most widely used consumer  high-resolution video formats, 720p (meaning 1280*780 pixels) and 1080p (1920*1080 pixels) are visible at all on the iPad 3's screen.



Looking for the best video player with even 24bit / lossless / 5.1 WMA / FLAC support? Here's the answer!

As my forthcoming iOS Multimedia bible will also cover playing back audio files not natively supported by iOS, I've made some serious tests to find out:

- whether special, high-quality (24 vs. 16 bits, lossless vs. lossy, 5.1 vs. stereo) WMA and FLAC audio files (these two audio formats are immensely popular among audiophiles) are played back by the universal (meaning also video-capable) multimedia apps I compare

- what the CPU usage (measurement methology HERE) is during playback in both foreground and background mode (if the latter is applicable – many basically video-centric multimedia apps aren't capable of this)



Multimedia player RushPlayer updated: quick change review - UPDATE: RushPlayer+ review & comparison

image

While, in the last week, several multimedia players have been updated (including my favourite, GoodPlayer, which, among other things, has clearly improved its DVD playback support in the current, 5.0 version), one of them I've already (quickly) reviewed (see THIS and also the comparison videos HERE), RushPlayer has received the most updates and new functionality. This is why I'm dedicating a separate (quick) article to it (but, currently, no other players).



The new iPad (3) for 2K(+) video playback? Definitely!

image

You might have heard of 2K video. It delivers (horizontally – but not vertically, at least not in the widescreen mode!) a little bit more resolution (2048) than Full HD (1920).



Welcome my latest app: Video Transcriber!

(A quick note: I know I've published quite a lot of articles in the last 1-2 days – for example, some three yesterday. The sole reason for this is that I, at last, have had some free time – as opposed to the past two years, when I had very little time for writing – and could resume writing. Hope I'll be able as much as back in the good old days of Windows Mobile ;-) ).

In one of my yesterday's articles (see THIS), answering a request from a forum member, I've promised I'd write an application that shows a text editing field next to a video player (with a Pause / Start icon) so that you can easily write a transcription of a video.



EXCLUSIVE: How I've restored the full potential of Full HD playback on the iPad 3 (with source code!) - UPDATED: new player

image

I've recently received an e-mail with a question from one of my readers, Eric Vinicius, asking for my opinion on the effects of upscaling Full HD video (1920*1080) to the slightly wider (2048 pixels) screen of the iPad 3 to fill it entirely and not to leave a 64-pixel black bar on the two sides of it.

Today, now that I've created a highly reliable, high-quality test video (it's available HERE), I've finally run some tests to find out what the situation really is.



Sure you can listen to the audio of a video in the background - or in a window pane

iMore.com has frontpaged a thread (it's HERE) asking about the lack of playing non-YouTube / non-podcast videos in the background; that is, only to listen to the sound but not watch the video itself.



This is how you can convert your DVB recordings' subtitles to iDevice-friendly MP4 subtitles

UPDATE (12/Sept/2012):  in the meantime, Subler, one of the best remuxer and MP4 editor tools has also received OCR capabilities. It has some advantages over the character recognition of SubRip, introduced in the article below. Please read THIS for a full tutorial.



Playing back 1080p60/i60 (M(2))TS videos right from your camera? - UPDATE: desktop converters tested

Over at DPReview, answering a question (thread HERE), I've elaborated on playing back both 1080i60 and 60p videos created by the new, highly recommended and popular Panasonic FZ150 camera so that this info can also be included in my forthcoming iOS Multimedia bible. As the info can be of interest to people before the Multimedia bible is finally published (which takes at least one additional week or two), I dedicate a separate article to the question. (Note that this article applies to all other cameras producing MTS, M2TS or TS – and not MOV / MP4! - files.)



Making the stock Videos application play every MP4 file possible

image

I've dedicated several articles (latest one HERE) to converting videos into MP4 (M4V / MOV) files so that they can be played back by the H.264 decoder of even older-generation iDevices. In the current one, I elaborate on how how you can play the output files with the built-in, stock Videos application. This article also belong to my Multimedia article series, in which I plan to publish a “Streaming multimedia over your local Wi-Fi” in the next few days and, then, finally, the real Multimedia bible.
