iamedi Posted March 23, 2006 Share Posted March 23, 2006 This may be a stupid question, but I'll ask it anyway.I have a show coming up rapidly and have just had the opening video edit dumped on me :o .The screen is 10mtrs wide x 4 high (2.5:1 ratio) and the client wants it full screen.We are running an EVENTIX 2 projector system for the screen already, but I'm not sure of the best way to get the video into this ratio (1315 x 576 pixels) including blended area.Is it just a case of doing it letterbox and scaling?Also the audience are only about 10-12mtrs away so need to get best quality possible.Any help greatly appreciated as show goes live in 9 days.

viktorkr Posted March 23, 2006 Share Posted March 23, 2006 Hello,dont know what are your editing cappabilities, but I usualy do this in after effects or final cut pro etc. and edit a PROJECT in 1280x512 pixel (2,5:1 aspect), and render the final video also in that resolution as quick time movie. If you have that done this already, simply use a computer with at least the same output resolution as the edited video which is cappable to play that video smoothly in full screen. You will have the video in full screen as letterboxed video, feed that in both EVENTIX with CROSS BLENDER and with SHOW MANAGER software, use ZOOM capabilities for that input and scale it to full screen. If you can use Mac as a player for that video, use the Cellulo player software, which is capable to play video in full screen and to "anamorph" it, so you dont have to use zooming on eventix.... Good luck, Viktor Just forget to mention that I will not go for a DVD or any PAL source for full screen video, and reason is hov much I have to scale it. When you scale from 768x576 to approx. 1920x768, it is much worse than scaling from 1280 to 1920 pix. Finally, as much resolution you can get for your video, the result will be better..... Hope this would help. Viktor Link to comment Share on other sites More sharing options...
paulears Posted March 23, 2006 Share Posted March 23, 2006 further to what Victorkr has posted, Don't that you will also lose a bit more resilution if you take a standard 4:3 image and crop rather than stretch to the new format size - then up-scale - you lose vertical resolution when you crop the bottom and bit of top off, so when you then expand that it looks a little 'granular'. applying a softening filter blends it a bit, but you can't recover the sharpness. This makes the comment about original quality even more critical. If the original stuff is from VHS in any way, it is going to look a bit rough around the edges.paul Link to comment Share on other sites More sharing options...
iamedi Posted March 23, 2006 Author Share Posted March 23, 2006 Thanks for the input on this.We are going to create a piece in AE at full res and "squish it" back to 1024 then let the eventix stretch it back out.Unless I've misunderstood the replies this should solve the issue??? Thanks againTim... Link to comment Share on other sites More sharing options...
Tomo Posted March 23, 2006 Share Posted March 23, 2006 If you have a choice of source resolution, for God's sake create it at the resolution you will project it at. Every time you reduce resolution, sharpness and detail is lost. It cannot be regained, no matter what CSI: Miami may claim. Link to comment Share on other sites More sharing options...
back_ache Posted March 23, 2006 Share Posted March 23, 2006 no matter what CSI: Miami may claim. ** laughs out loud **! We'd all love one of their video scalers! :o Link to comment Share on other sites More sharing options...
iamedi Posted March 23, 2006 Author Share Posted March 23, 2006 Thanks Tomo,Unfortunately all source material is Pal 4:3, so gonna create a nice background in AE or similar (topic relevant of course) :( and genrate final piece at full res 1923 x 768 and get the lucky editor to fly elements around a bit.Is it really mean of me to have hooked the client into the editor direct :o Thanks for the tips.

James Posted March 24, 2006 Share Posted March 24, 2006 iamedi, If your source material is 4:3 non anamorphic and your delivery medium is 10:4 don't you have a problem. ? You do realise that if you crop this you will end up with effectivly 307 lines resolution on your source material don't you. Also what Is your delivery format going to be?

iamedi Posted March 24, 2006 Author Share Posted March 24, 2006 Hi James,Yes the source material is 4:3, however if we use it as PIPs in the full size segment 10:4 and have smaller PIPs floating around waiting be scaled up as the front segment then scaling back and away, I think we should get away with it. Playback will now be done via either PC or Mac haven't decided yet. Tim... Link to comment Share on other sites More sharing options...
