Interesting TH2go content creation discovery

[PCProject]

New to me. Others may have already posted or know about this.
I have been making projects/compositions in After Effects at 2400*600 and rendering at the same size.
Earlier I made a mistake and rendered at 800*600 giving me a squashed clip when looked at in a media player BUT when played back in avenue at 800*600 and output to the TH2go it was stretched back into its original aspect ratio.
Anybody got any thoughts on this? I need to do some more tests to see what is happening to the quality but on the one clip I have it appears to be ok.

That's called Anamorphic


its a good idea if your finding your clips don't playback smoothly as your reduced resolution will be less taxing to playback.

Brilliant. I had wondered what people were talking about when refering to anamorphic and had never made sense of stuff refering to it. I am shit at reading technical documnets.
Are there any useful tips, as I think I have seen an anamorphic setting in the render options?

It's the same as having a "16:9" video stored as a PAL (or NTSC) 4:3 video. You simply have x pixels across and y pixels down, stretched to whatever shape the output/screen is.

I've had a thought recently to using video scaled to 512x512 (262144 pixels total): a bit less horizontal resolution, but greater vertical resolution than 640x480 (307200 pixels total), overall 85% of the higher pixel count. Why do this? Well, graphics hardware likes to do things in dimensions that are powers of 2. If you want 640 pixels wide, that might occupy a buffer or texture that is 1024 pixels wide.

Similarly, you could try rendering your clips at a slightly reduced triple-head resolution, say 2048x512 (1048576px), and see what performance benefit that gives you. Maybe 1024x512 (524288px) will be good for you, if you're finding 800x600 (480000px) to be okay.

it is however worth remembering that when using avenue some odd things happen with some of the effects if the clip sizes are different to the final composition output size. ( i only mention that as i know you are an avenue user dave )

Well my thinking was for a gig where there are 3 x 800*600 native projectors available this might be my best approach for content and lose a little on the overall resolution.

you know I've never bothered with the higher res triplehead stuff, I make everything at 1920x480. even if the beamers are XGA, it still looks good, and the performance of my machine is right where i want it.

just sayin..
