soz folks, This post could well go on all day with my lack of braincells.
Just tried exporting a test movie now. AVI. but the quality is cack, what do I need to do?
- paddywop0
from where? You mean rendered?
- Bullitt0
rendered?
wheres that option? I've just exported from the composition?
wrong?
- vespa0
composition > add to render queue
make sure your quality is set to best and resolution is set to full
- Bullitt0
Okay done it, thanks, when I play it though in a mediaplayer the framerate has dropped to about 6!.
Had it set at 29 fps in the comp, anyway of fixing this?
- paddywop0
in the render window, click on best settings and choose 'use comps frame rate'.
As for media player, why? Why not quicktime?
- vespa0
check your composition settings.
otherwise check your render settings in the render queue.
- Bullitt0
nah, rendered it as a quicktime movie this time, runs smoother but starts stalling in framerate again halfway through the clip, didnt think it was possible to loose framerate within a movieclip?
the effect I created is a bit like the old Pearl and dean advert they used to show in the cinema;s years back, so its a compination of many 3d blocks moving down a tunnel, i used a motion blur effect on them and also the keying on the blocks. Could all the effects I've added cause the loss of framerate? is there a way of flattening the effects to increase the frame rate?
- paddywop0
nah matey, once its a quicktime it is flattened. Frame rate will not be affected by effects at all.
What it might be is that maybe you have rendered the quicktime uncompressed, therefore its a big file size, and then a lot of computers struggle to play them without stuttering. Could that be it or do you mean something else?
- Bullitt0
yes mate, I think its maybe uncompressed, file size is over 100mb for a 6 second clip.. how do I compress it down?
- chossy0
just lower your quality,
in format within your render settings click animation compressor and reduce quality.
there is allot to learn before you can get things rendered in the correct way, once you have that you are free to just creat masterpieces, :D hang in there man it won't be too long before you are kicking ass.
- paddywop0
man thats big, what aspect ratio are you using?
- Bullitt0
Iam doing stuff to run at fullscreen at an expo in vegas next month, ratio is 720x480

If you use QT then use Sorenson 3 and play around with quality settings.
Because if you don't compress your movie, your every frame will be about 1 meg (like uncompressed .tif). Now imagine if you have 6 seconds with 30 fps then you have 180 meg file on your hand.
Even if you do something for TV you still compress it for eighter PAL or NTSC.
About your background keying problem. What program you used to make that 3d anim? I suggest you render out .png sequence with alpha channel. Then you don't have to key anything out (because Key Color filter is shit and to get better results you need proper keying filters).

Sajets, Iam using 3dswift6.5, il check if theres such an option.
- chossy0
sajets you are not correct there, I never use compression when outputting my files for TV.
Basically bullitt your computer cannnot handle the data rate, when you are giving it to the person who is mastering it onto tape or DVD, you must use uncompresed 10 bit 4.2.2 or your project will not I repeat not be the best quality. I use Black magic 10 bit and also uncompressed 10 bit 4.2.2, give whichever production house you are using the file as a quicktime they will then sort the end process out for you :D

If it doesn't then one other way to do it is to render out your animation with all the objects being copletely black (no highlight whatsoever) on white background or vice versa. Then import that sequence also to AE and use it as luma matte like decribed above but this time you will have accurate alpha.
I always do it like that if i can't render out PNG with alpha.
- sajets_v20
chossy - what i meant was that if you render out using PAL settings the video will always be compressed. It was an example and not that i do it like that.
When i render something out for TV i render it out as PNG sequence and sound separately. Then in TV studio their techincans will import them and record them straight to BETA.
But analog TV picture in itself is compressed. Or am i wrong here?
- Bullitt0
Chossy,
Where abouts is this animation compressor exactly?

Hit Ctrl+M (PC)
Make movie window pops up. Select Best Settings for Render settings and for Output module click on "Lossless" or whatever is your default.
Another window comes up:
Select QT for format. Then click Format options and select whatever compressor you like to use.
