Kindle Fire HD

[tarzan54]

Just got a Kindle Fire HD, I want to put some movies on it for when I travel, What does anyone suggest as the best way to do this, I assume I would have to convert the movie with some kind of video conversion software that supports the Kindle.

You need to decrypt the BD/DVD's first then use Handbrake to convert:

You might also get the app mentioned in this thread:

xmediarecode has a preset for the kindle fire hd

Thanks Guys, The video from youtube was very helpful, I'm going to try both xmediarecode & handbrake to see which is better or if their is any difference between the 2.

Don't forget the Kindle Fire is a triumph of marketing over substance. It is HD but only when plugged into something that can display HD, it's SD on it's own display.

KindleFireHD's "1280 x 800" > 1280x720, which is surely considered HD by the vast majority of consumers & professionals (particularly at that screen size), so I don't know where you are getting this SD business...

You must be an Apple fanboy since Apple has been marketing style over substance for years.

As Scott mentioned the HD models are 1280x800 or 1920x1200:

Definitely not an Apple fan, all I'm going on is the Kindle Fire HD that my father was given as a Christmas present does not display HD on the screen, only when plugged into an HD display. 1280x800 isn't HD in my book, 1920x1080 is.

Since when is 720p (1280x720) not considered high definition?

maybe with 4k displays now available standards need changing. <(\

I think we are getting ahead of ourselves by re-evaluating the criteria for calling something HD. There isn't a great deal of video available for home use yet that goes above 1920x1080 resolution. Anyway, those displays have already been officially dubbed "Ultra HD".

it was a joke. sometimes levity is needed around here. the old "wizard with a wand" got kinda wacky with auto smiley detection.

Years ago, when digital HD was just starting to become available, this had been a point of contention, but it was ultimately and finally decided by Industry consensus:

720x576 or lower, interlaced is considered SD (standard def).
1280x720 or higher, is considered HD (high def), whether interlaced or progressive.
Anything in-between, plus 720x576 or 720x480 progressive, would be considered ED (extended def).

This is what all techies & marketers have been going by since ~2004.

Now, 2k, 4k & 8k are being added to the mix. Since 2k is nearly the same as 1080p, that still falls under the realm of HD. 4k & 8k are already being included under the new, and fairly agreed-upon term of UHD (ultra-high def).

Like I said a moment ago: on a screen the size of 7", a 720p image should look IDENTICAL to a 1080p image. Doesn't just have to do with the # of pixels, it has to do with the resolving power of our eyes (aka visual acuity, ~1 arc minute), so this includes the size of the pixels themselves (partly determined by the screen size) and the distance of the viewer from the screen.
IOW, even if you had a 4k screen, it couldn't look any sharper to you on a 7" screen at normal viewing distances, compared to 720p resolution. It's not just personal, anecdotal labelling going on here, it's objective, scientific designations. *

Don't really know where Apple ever entered into this...?

*(although at the beginning of Television, the electronic tube scanning format was considered HD compared to the opto-mechanical formats previously tried (which had an equivalent resolution of ~240x180 @ 30Hz)

Thanks, I have the flu, so I needed the explanation. Couldn't figure out what the extra characters meant.

Thanks for all the information, I was hoping my kindle fire HD played HD movies at least that's what I thought the HD stood for and it does list as a 1280x800 high definition LCD display , guess I should look more into it before doing movies on it.

According to Amazon, the Kindle HD plays 720p video, which qualifies as HD, but the video has to be provided in a form it can use.

I was only going on what my father told me at Christmas. He was complaining that the Kindle Fire HD only did HD when plugged into an external HD display. It now transpires that he was expecting that something with the HD designation would run at full 1080p and nothing less. However, it is something that needs to be taken into account when converting movies to put on it. There's no point in filling it full of files at 1080p that it can't display, when 720p will take up far less storage space.

Technically, being 720p instead of 1080p does NOT automagically make a file smaller. As always, it's bitrate, bitrate, bitrate. Yes 720p should be able to use a lower bitrate than 1080p but it doesn't have to.

I've got an even cheaper Android knock-off, and it can display 1080p on its 800x600 screen. It just resizes it down (plus, stutters like crazy because of the bitrate bottleneck). I'm pretty sure the K.F.HD. could do the same. If the bitrate were in the usable range of its processor, it should handle it fine.

Doh, jman98 got to it first!

usuaully_quiet, Your correct about the Kindle fire HD displaying 1280x800 resolution an video playback at 720p, So guys, When I convert my movies to the kindle format do I use the 720p setting?

If the source is Blu-ray then yes, if it's a DVD then just use 863x480(16:9) and let the Kindle upscale.

[aedipuss]

the kindle has a dual cpu and dual gpu like my nook hd+, so it shouldn't have a problem with any 720p video. i'd use the xmediarecode kindle mp4 preset and only change the bitrate control to cq and start with maybe a cq of 20 for it. adjust down for higher quality and larger filesize, higher number cq for lower quality smaller filesize.

[aedipuss]

and the video size is on the filters screen

[tarzan54]

Thanks aedipuss, Great guide on how to use the program xmediarecode for kindle, I will give it a try.
