The Multimedia Player KMPlayer Now With Stereo 3D Support As Well

April 29th, 2012 · 6 Comments · General 3D News


When talking about a good general audio and video player three names quickly come up in my mind – Media Player Classic, GOM Player and KMPlayer. All powerful both in terms of features and options available to the user and easily playing back most audio and video formats, but this goes as far as 2D video. The it seems that these players could soon also support 3D video playback, for example the GOM Player has gotten stereo 3D subtitle support some time ago and more recent beta builds of the KMPlayer also do come with support for stereo 3D subtitles as well as stereoscopic 3D video playback capabilities as well. Have in mind though that when talking about stereo 3D subtitles support with these players it means support for plain text file subtitles used for 2D videos that are just being played back properly at screen depth in 3D mode. Regarding the supported stereo 3D input formats the KMPlayer can handle videos in Side by Side or Top/Bottom (Over/Under) and can display them in multiple anaglyph output modes as well as Row or Column Interleaved format. So you wither need a pair of anaglyph 3D glasses or a passive 3D display that can work with direct Row/Column Interleaved input such as LG’s 3D monitors and 3D HDTVs, unfortunately there is no support yet for 3D Vision for example. So next up is Media Player Classic starting to get some stereoscopic 3D support as well…



The KMPlayer also has some sort of an online service for accessing 3D videos called 3D Movie Plus, however I was not able to see any videos available as in the example screenshot above, so this may only be working in Korea for example. And while neither the GOM Player, not the KMPlayer are yet even close to offering what the Stereoscopic Player supports in terms of stereo 3D video, they are still much better in 2D video playback. So if you have never used Media Player Classic, GOM Player or KMPlayer, then I’d recommend to check them out at least because of their 2D multimedia playback capabilities.

Using GOM Player for 3D Video Playback with Subtitles on 3D HDTVs

February 11th, 2012 · 1 Comment · Other S3D Tech


One of the common complaints by the new to 3D users from the usual 3D video players such as the 3D Vision Video Player and the Stereoscopic Player is that they lack some features that have been common for quite a while on other 2D video players like Media Player Classic, KMPlayer, GOM Player, VLC etc. Unfortunately none of these few very popular and widely used media players does have full stereoscopic 3D video support, but some of them do have some useful features for people watching 3D videos as well. I’m going to be talking about the GOM Player here, as it is one of the first to implement some stereo 3D-related features in its official version and more specifically 3D subtitle support. This means that when playing back 3D video sin Side by Side or Over/Under format you would be easily properly overlay 2D text subtitles over the video in a proper format, so that you would get 3D subtitles displayed at screen depth. An easy to use functionality built into the GOM Player that everyone can use without having to go through adding additional filters and configuring them as is the case with using the ffdshow subtitles filter for example, but also not as flexible and as functional as the external ffdshow filter for subtitles.



To activate the 3D subtitles support in the GOM Player you need to right click on the video player, select the Subtitles menu, 3D Subtitles Mode and choose Disabled for 2D subtitles, Left/Right Mode for Side by Side and or Top/Bottom Mode for Above/Below videos. Have in mind that the choice you’ve selected remains until you close the player or select something else, so even if you play a 2D video after watching a 3D video with activated 3D subtitles support, the subtitles will still be shown “doubled” in the 2D video, so you would have to switch to 2D mode. Closing the player and then running it again however resets the 3D Subtitles mode to the default Disabled state, meaning the normal 2D video support.



When switching the subtitles to a different mode for 3D videos the on-screen messages overlayed on the video from the player also change correspondingly to reflect the 3D format of the video being used. What is left however is to also do the same with the playback controls of the player at the bottom of the screen that still render in 2D. So a job well done for the authors of GOM Player, but there is more to be desired in terms of stereoscopic 3D support that can be added in the software. Have in mind also that the 3D Subtitles functionality of the GOM Player is only useable for playing back 3D videos with subtitles on 3D HDTVs with manually activating Side by Side or Above/Below input mode. GOM Player does not support HDMI 1.4 frame packaging or frame sequential output for 3D content and is not compatible with stereoscopic 3D solutions such as the 3D Vision, so it is not a complete replacement for the 3D Vision Video Player or the Stereoscopic Player, just an alternative that you may use in some cases.

3D Subtitler, a Tool For Easily Converting Subtitles for 3D Videos

September 3rd, 2011 · 15 Comments · 3D Movies & Videos


Adding proper subtitles to 3D videos can sometimes be a real pain, even if you already have the subtitles in a text format such as SRT, something that is quite common for 2D videos, but still not as useful for stereo 3D ones. There is the ffdshow subtitles filter that you can use for displaying 2D subtitles properly over a 3D video file, but that method is a bit more limited and can cause some problems setting up and using. An alternative method is to convert the SRT subtitles and integrate them into the video, but I’m not talking about recompressing the whole video and hardcoding them inside the video frame, there is no need to do that. With the help of the free 3D Subtitler software you can convert the 2D SRT text file into the proper format for using with Side by Side videos or Over/Under formatted ones, adjust their position, font size and style and border. Then have the newly prepared subtitles integrated into an MKV video file using MKVmerge (MKVtoolnix) or into a Blu-ray video image with the help of TsMuxeR. As I’ve said this is done without hardcoding the text into the video, so you are able to enable/disable the subtitles at will. Of course using 3D Subtitler requires a bit of time to process the video with the properly prepared subtitles, it is not as easy as to just open the 3D video file with a player using the ffdshow subtitles filter and having the SRT subtitles in the same folder. But still the 3D Subtitler tool can be a useful alternative if you are having problems with making the ffdshow subtitles functionality to work properly for you.

Both of these solutions however will output by default the 2D text subtitles as 2D subtitles appearing at screen depth level, they will not make them into 3D ones that will have varying depth based on the depth information from the current scene of the movie. So if you have the subtitles displayed at screen depth level, but the current scene has some pop-out effects below the position of the subtitles you will be experiencing trouble getting the correct volume information. The same applies if the scene at the position of the subtitles uses a lot of depth, again making it hard to properly focus on the text and the image from the movie properly, making it uncomfortable for the viewer. That however should not be a very common problem and getting rid of it would require a more robust software for preparing 3D subtitles, not to mention that it will also require more knowledge and skill to be properly done, so it is not something that normal users would usually do. The results provided by the ffdshow subtitles filter (it also has parallax adjustment option for the 3D subtitles, but you can set it only once for the whole video and not vary it through the subtitles) or the use of the 3D Subtitler software should be quite good most of the time and easy to use by most people.
