VDJ. Whats it take to get this right? Alot of videos now are coming out as proper standard ratio 16:9 or 640x360.

It can't be that difficult to make VDJ not stretch these videos to 4:3. If its a budget thing let me know so we can work something out. I've tried ffdshow & had no luck. Video is one of your big selling points......y cater to 4:3?? Enough is enough.

Its hard to even buy a 4:3 tv anymore. Y cater to 4:3?

Simple. Make it possible for active picture videos to be played within vdj without being stretched out.

Make sense? It should.

Now catering to the 16:9 world :-)

I used my monitor on the night before last for the first time, the res is 16 something is this why when I tried to get it to work it took ages basically in the end I stretched the box to fit the screen.

In config/video I ticked the activate box in the video output section however my monitor did not appear in the drop down box, does anyone know why?
 
Extend your desktop in windows to the second display, and it should appear :)

If you extend your desktop like SBDJ mentioned then your videos will work on most widescreen (16:9) televisions and Projectors.

However I think what your asking for is to have VDJ re-format the videos automaticly when being displayed?

That's something that's out of their hands, most nweer videos will be made for widescreens but older ones will not. I don;t beleive there's anything to be done about itexcept spending the time your self re-formating all your videos on your harddrive.

That sounds like a lot of work for minimal gain.
 
hehe okay. didn't really think that message was replying to my post. uhh yeah that will kind of work...but only for the active picture videos. but then all the other 4:3 videos will not look right at all.

You don't have to convert your whole library when dealing with active picture videos. a letterbox 4:3 video...yes. but again right now if u play a 16:9 video NOT anaphormic, a active 16:9 video (640x360), vdj will stretch it vertically to fit a 4:3 ratio. I'm suggesting to vdj to make it not do that. Just a disable check box would cure it. To be able to "preserve" its aspect ratio is gold.

Not trying to compare but have to, Serato is doing it right, soon after that Traktor is coming & i'm sure will be molding after them. Video is the future, also is 16:9, so it just makes sense.

Hopefully that puts it in a better perspective SBDJ & Marcel. anaphormic is not the right way for us to play music videos.
 

I agree this needs to be done: "So powerful yet so easy".

Sorry, you are correct, I was replying to the post above about the output not being selectable, nothing to do with your AR post.
 
i didn't think so but i guess its Marcel's fault :P hehe

I think right now is a real good time for everyone to come together & show the need to vdj. I guess my next step is to show hands on maybe I'll even shoot another video of what or how its suppose to be like.
 
I always thought this was a function of the tv as VDJ does not know what the format needs to be for each individual tv, it only sends out the format the video is in. Most new tvs have a setting in the menu that shows the incoming video stretched to the proportions you chose, streched to the actual screen proportions or reduced or enlarged to retain the proportion recorded in but fit the whole video on the screen (this is the setting you want if you don't want any stretching i..e if you have a 16:9 proportion screen and you send it a 4:3 video the screen will show it as 12:9 there by leaving the picture without stretching or distortion and the appropriate black space on the left and right of the video to fill the 16:9 size.

Also keep in mind a lot of videos are recorded in 4:3 proportion but then letterboxed (i.e. intentionally leaving the appropriate black space RECORDED in the video to show them as 16:9 on 4:3 tvs.....I hate these becasue then on 16: screens they look really small with lots of black space all the way around them as the tv thinks the black space on top and bottom are the video so it still puts the black space ont he left and rignt.

Just as a matter of note, on most of these monitors if you have them set to stretch the video to fill the screen I have found if you are using the text2d plug in it will NOT show on the screen where you want it.
 
ehh but not really a solution for us. You can't hope that the club that your going to be at has the monitors with these features. Especially projectors etc.
 
As far as i know, most projectors offer a control for either 4:3 or 16:9. The vast majority of European music videos are at 16:9 with a res of 720 x 576 Pal.

PAL widescreen is 720x576 with a pixel aspect ratio of 1.422

Perhaps a conrol in VDJ to change aspect ratio of secondary video output is the way forward.
 
Displaying the correct aspect ratio shouldn't be the function of the monitor or tv, some may have an override but it should not be necessary. NTSC DVDs are 720x480 and PAL DVDs are 720x576. Contained inside the video stream is a flag signalling whether the video is 4:3 (which causes conversion before being display to 640x480 or 768x576 respectively. For 16:9 content the sizes are 853x480 and 1024x576. Any other aspect ratio is letterboxed, e.g. 2.35:1 will contain large vertical black borders and a 16:9 flag.

Virtual DJ wouldn't need an option to change the aspect ratio of the secondary output, it needs to support the feature of aspect ratios first. It can determine the appropriate letterbox required based on the resolution for the output as all LCDs and Plasmas have square pixels.
 
The output window of VirtualDJ when set to full screen is stretched to whatever resolution/aspect ratio that display happens to be. So, if say the display a 16:9 1080p LCD on the wall, VDJ will stretch its output to that. Now if you're playing widescreen videos with a resolution of 640x360, the output will be correct. Because 640x360 and 1920x1080 both happen to have the same aspect ratio, 16:9 or 1.78:1. So in a sense, VDJ already kind of does support WideScreen videos ;)

As long as your input and ouput AR match, VDJ behaves correctly. Start mixing ARs, and you run into problems. Now with the above setup, if you feed it a 4:3 video (let's say 640x480), THAT will now be stretched to 16:9. Like others have said, VDJ needs to add a 'preserve aspect ratio' function, where the AR of input video is calculated and when scaled, the source AR respected.

Also note that the above examples are applicable if your ouput display is connected via HDMI/DVI/VGA, where different resolutions are possible. If you connect a display via composite/s-video, the computer has no idea whether you have a widescreen or fullscreen display conected and defaults to 4:3 output because that's the nature of analog video. In order to send a widescreen signal via composite/s-video, it would need to be anamorphically squished durng playback and stretched out by the TV/display. The funny part is that this will already happen, kind of a positive side effect of VDJ's missing AR support and most clubs' . With most VJs connecting their setup via composite (so the computer outputs 4:3) and most plasmas/LCD's set to "stretch", playing 640x360 video in VDJ WILL YIELD proper display, unlike what's happening now, where all 4:3 video is being distorted to 16:9 and all "widescreen" videos living letterboxed in 4:3 frames are being distorted AND have black bars on the top and bottom that don't need to be there.

Furthermore, support for non-square pixel video should be added as well. Like andrew87 mentioned, both 16:9 and 4:3 may exist in a 720x480 mpeg-2 stream and it's the flags that tell the player how to display it. This is also possible with h.264 video in the MP4 container, via PAR, SAR and 'pasp' flags/atoms.
 
interesting about regular tvs. too bad their basically obsolete now.

this a very very important feature that is currently overlooked.

maybe a plugin would do the trick for the time being.

Just incase the developers are reading this thread. I'm another user that would find this feature useful.

Like somebody mentioned already, I guess the best thing would be an option somewhere for what screen ratio you're using (4:3, 16:9, etc) and then vdj could add black bars as appropriate (or maybe even take them away as well if the programmers are feeling clever).

Just thought, it's basicly whatever code is used in the photo slidshow plug-in to make photo's fill the screen and be centred, then simply leaving the remaining space black. Obviously, nothing's ever as easy as that, but I guess it must be possible.
 

I think this would be useful for anyone who's using the video features in VDJ, it's just they don't know on first glance of this thread.
 
I'm willing to pay someone to design a plugin to make it work. Payment on delivery

Any takers?
