View Full Version : viewing final rendering

I was wondering how companies can put their "animations" on tape and stuff.
How do they compress their final renderings ?
Into .Avi or .Mpg or DivX maybe ?

I'm asking this cause i have rendered a scene at full 1024x768 .AVI
Without compression the animation is just plain jerky.. it seems like the videocard doesn't want to or have enough bandwith to output the 2 gig animation onto the screen.
I have tried running the animation on screen res. 1024x768 and 800x600 (only the res. of monitor, animation resolution stays the same)

So what compression is best that is "good" enough for tv ?

Grazie !

Yes studios do compress the video in order for it to play on the system. Also they may have a special video board in order to compress it and play through the cards "memory". I say special because this is aside from your regular video board that runs the VGA on the system. We use a DPS velocity. You can check the name on the net if youd like to know more.

Couple of specifics: 1)When you render frames from maya look under the renderglobals and in the sizes there are presets for television probably the bigest will only be 720x486 or 640x480. (tv cant display more yet) Film res is also in there.

2)Also what are you using to compile the shot in? Aftereffects, combustion? Well render from whichever to either Quicktime/sorenson codec compression, or if you like avi's try exporting to mpeg1,2,4.
Hope this helps. If you have other specific questions just ask.

OOps! Just saw your location is netherlands. You may want to use the PAL then if your on European standard settings. U.S. studios usually use NTSC if its going in that direction.

so rendering at 1024x768 is just a waste of rendering time and drivespace ??

well...here it is:For europe PAL (720*576) and fields or motion blur if you are going to composite over live action.And rendering in Avi is not a good idea.Render in a sequence of tga or tiff images,you can later save an avi out of them.:)

i work at a company that does comercials and they let me do all the cg at home... its in the states. so i work at 640 * 480 but the key is to make it quicktime and cinepac compresion at 90 percent (so that it isn't that big a file) cause anyway a lot of the quality will be lost when thay put it into media 100 (which is the editing program they use where i work at) and they play their projects realtime so you don't want it to be too time comsiming for the program (and video card) to read the file


hope that helps..

sincerely
