Hi,

I am working on a project involving video playing at 1 fps, it renders fine when I use the Microsoft Video 1 codec but the quality is rubbish and the file size tends to be huge..

I have started using the DivX codec but it is interpolating the frames, making the video very hard to watch.

Is there any way to turn this off?

I have attached a small clip to demonstrate what I'm talking about.. just change the file extension to .avi ;)

TIA

Re: Turning off interpolation

Hi,

DivX Codec is not doing that, your video software is. The clip is encoded at 24fps, and I imagine your video software is applying a filter that tries to adaptthe input clip's 1fps to match the output setting of 24fps by blending.

Check that whatever video application you are using has the output fps set to match the input fps exactly.

Other things: For 1fps video you might want to turn off bi-directional coding. B-frames are interpolated (though not related to what you're seeing currently) and encoded at lesser quality than I/P frames.
