View Full Version : What are the best 1080p HD video formats?

January 12th, 2011, 04:22 PM
I'm just a bit confused here with all these different HD video file formats available? I see the main ones are: h.264 with .mp4 and .mkv file extensions.. is that correct?

what file size is smaller (better compression) but renders a higher quality video? what format is most similar to using a BlueRay player at 1080p?

and where on the internet do you find these 1080p high def video files? I have often downloaded video files over the internet but they are usually .avi file extension and they are usually only standard definition (dvd quality).

besides that, anything HD I have has always just been through BlueRay discs.. I would like to do away using any form of dvd player, but instead just be able to download the 1080p videos to my harddrive and get the same 1080p HD BlueRay quality.. is it possible?

and where on the internet do you find these 1080p high def video files?Most people rip their blu-ray collection.

Vudu rents/sells 1080p content (only viewable through their app though).

Amazon probably has some 1080p content as well.

If you're talking about downloading for free, then all the usual places :p

what are the BEST (best quality and smallest file size, best compression) 1080p video formats to use? .mkv, .mp4, etc. etc.?

and how does Divx compare?

The Matroska Video container (.mkv) with H.264 encoding seems to be becoming the de-facto standard for compressing high definition content like XviD and AVI was to DVD.

^^good question.. not meaning to hijack your thread, (lets call it expanding your topic) but what exactly is the advantage of divx. It has always seemed to be clumsy and slow for me.

What makes it better than say... mp4 which is what i use.

Have you folks read through this thread? http://forums.boxee.tv/showthread.php?t=22632 Your questions might be better suited there :)

yes i have.. i even attempted ripping a few movies with the presets and suggestions but it seemed to cause larger file sizes, longer encoding time that using the default settings which have always seemed to work on every player i try. I moved back to my old settings.

Although have still wondered why everyone seemed to love divx so much.

The video quality of an AVC (h.264) .mp4 file and a .mkv file created with the same encoding settings will be identical.

The Matroska (.mkv) container is much more flexible in that it can handle a wider variety of audio, subtitle, and chapter formats. Therefore, it's ideal for use on personal computers and HTPCs (I consider the Boxee Box, from the perspective of media format support, to effectively be a Linux HTPC).

The Mpeg4 container (.mp4/.m4v), while being more capable than some other containers, doesn't officially support surround sound formats like AC3 and DTS, but it has the advantage of enjoying support on more devices, especially game consoles like the PS3 and XBox360 and portable devices like smartphones. The only major downside is that you're stuck with stereo audio for now.

Boxee and the Boxee Box will happily play back both formats. What you need to consider when deciding between them is compatibility with any other devices you may use regularly and whether or not surround sound is a priority.

DivX and XViD are (were, actually, DivX now actually uses their own version of h.264) roughly comparable, with DiVX being the commercial, proprietary implementation of Mpeg4 part 2 and XViD being the open-source, free version of Mpeg4 part 2.

H.264 is, technically, Mpeg4 part 10.

XViD is definitely the most mature, best supported implementation of Mpeg4 part 2 since DiVX, as a company, moved to h.264 with "DiVX Pro".

Additionally, this movie (http://www.bigbuckbunny.org/) has been released under the Creative Commons license and is offered in 1080p.

Well, the Boxee Box's only video output is the HDMI port, so I'm not sure what you're asking.

If you're asking if it supports other resolutions: it does. The Boxee Box should allow you to set it to your display's native resolution, and it will upscale/downscale content that uses lower and higher resolutions than that of your display.

This is the first place that comes to mind-


Just right click on the res you want and save link as. If you download multiple, I would suggest renaming at this point too as they usually are default to just a number.
