3D TROUBLE SHOOTING
DVD skipping/freezing? This could be a bad disk, but it can also be caused by older DVD players, or by playing field-sequential disks on game consoles (Playstations or Xboxes). If you have access to another DVD player, try the DVD in it and see if the freezing/skipping persists. If you are still having problems, contact me.
Anaglyph Tip: Most people (myself included) report that anaglyph 3D content often looks better on a computer monitor than on a television screen. This is particularly true if you are watching 3D on an older TV. Computer monitors tend to hold colors much more accurately than do some televisions. However, newer televisions (LCD, plasma, etc.) tend to do a better job than the older TVs.
Generally, all 3D is best viewed in as dark an environment as possible. Also, glare on a TV screen displaying 3D content will usually ruin the effect altogether.
If you are viewing DVDs on a standard CRT television (aspect ratio 4:3), make sure your DVD player is set for your TV. 4:3 Letterbox is the correct setting for most of my DVDs.
**Field-Sequential 3D just doesn't look right? If you are NOT seeing double images, BUT the 3D just doesn't seem to be working, you might need to change the mode/phase (this is the most common problem people encounter, as many people have no idea what that button on the sync box does!). The button on the front of most viewing systems switches back and forth between mode settings. If the 3D looks weird, try pressing that button once to see if there is any improvement. Not all field-sequential DVDs are encoded with the same mode/phase, so one setting will not work for all DVDs. ALSO, if you are using the Virtual FX system, make sure the unit is set for 3D input and 3D output.
Seeing double images with no 3D effect? Most standalone field-sequential viewing systems REQUIRE an old-fashioned CRT (cathode ray tube) type television in order to maintain the 3D video encoding. If you are sure your TV is a tube-type television, it could be that your TV or DVD player may be set to progressive scan. This obliterates the organized interlaced signal that is required for proper field-sequential 3D viewing. Check your DVD player and/or TV video settings and look for a progressive (p)/interlaced (i) option for video input AND (more importantly) output. It should be set for 480i (not 480 p). Also, in some rare instances, I have had people encounter this problem with widescreen DVDs because their DVD player forces progressive scan on widescreen DVD video to improve the video that is resized to fit on a 4:3 (standard/full-screen) television. You can try changing the DVD player video output setting to 16:9 aspect ratio to see if that helps...otherwise contact me as I may have another solution for you.
Faint ghosting? Ghosting refers to the existence of a faint double image in one or both eyes when viewing 3D content. To confirm its existence, you can close one eye and see if you can see the faint double image through one or both eyes separately. This condition can be caused by a couple of factors such as too wide of a separation between right/left eye views, brightness/contrast settings on the TV, the hardware used (glasses or monitor) or image bleed between the two viewpoints due to poor DVD encoding or more commonly when a field-sequential 3D movie is converted from anaglyph (red/blue) source. The easiest thing to try is switching to another pair of glasses to see if there is any improvement. I have one pair of wireless glasses that exhibits ghosting on every movie, while the other three pair are fine. The next best solution may be to adjust the brightness/contrast on your TV/monitor to see if that makes any improvment.
If you are using a Virtual FX wireless viewing system, you may have your parallax setting adjusted too high (which means wider separation between the left/right viewpoints); if the ghosting is NOT visible when viewing the video with only one eye open (and try both!), this may be the cause. Lowering the parallax setting value should bring the right/left views closer together and reduce ghosting if that is the cause.
Most DVDs have a 3D screen test so that you can judge if you are getting any bleedthrough between the right/left viewpoints and whether or not your polarity/phase setting is correct...with one eye open, you should only see ONE clear image...if you are seeing ghosting on these screen tests, the cause is most likely something with your setup (TV, glasses, software configuration, or DVD player) as these screen tests are 100% clean separated images. On my CRT television, I always see some minor ghosting on these screens, but on my DLP TV, the ghosting disappears altogether.
Tri-Def users: The "d" button on your keyboard is the shortcut for advancing through the software's various 3D formats. The defalt is 2D, so if you are using the Tri-Def media player and the video is not in 3D, try pressing the "d" button a couple of times and see if there is an improvement. Check HERE for Tri-Def software keyboard shortcut list.
