Hi Ivan,

Thank you very much for you thorough reply!

I will have access to the laptop next week and until the time of the presentation. I will not have access to the actual projector until then (except perhaps briefly, in which case I will prepare some test projects at different fps etc. to see what looks good), but I will have access to another projector in the meantime so that I can verify that the playback performance of the machine as such is good enough.

I’m in Europe, so I guess 25fps for me then. The only thing I worry about is choppiness in some parts of the animation where there is quite a bit of horizontal motion – is there any reason beyond file size/bitrate why 50fps is not a good idea? I imagine I will at least create a 1024×768 50fps test file to play side by side with a 25fps one if I get a moment to test with the actual projector that will be used.

You are correct in your point 2 – so I will give these settings a go.

I am fortunate enough to only have to deal with local playback (no streaming, everything is coming from local SSD), so I have few restrictions on file size/bitrate. I will experiment, but sounds like a bitrate of around 15Mbps will give me what I need. I’ll test different encodes of the high/baseline profiles you mention to see what looks best.

When you say keyframe distance – we are talking about the compression concept of keyframe, right? This has nothing to do with the keyframes I use for my animation in After Effects? Sorry for what must be a really stupid question, but I am new at this and just need to make sure.

And finally, thanks again – a LOT – for your extremely helpful answer. I will note down your tips and make sure I test this until my eyes bleed. My background is actually as a programmer, and I practice something called Test Driven Development, so having the safety net of testing is very comforting when I’m on “thin ice” like this. 🙂

Again – thanks!
