This paper proposes selection of Intra prediction m odes for Intra frame coding in Advanced Video Codin g Standard using Matlab. The proposed algorithm selects prediction modes for intra frame coding. There are nine prediction mode s are there to predict the intra frame in AVC using Intra prediction,but all t he prediction modes are not required for all the ap plications. Intra prediction is the first process of advanced video coding standard. It predicts a macro block by referring to its previou s macro blocks to reduce spatial redundancy,appling all the prediction modes to pred ict intra frame it leads to more computational comp lexity is increased at the encoder of AVC. In the proposed algoriyhm, applied all the prediction modes(0-8) for prediction of int ra frame but only few modes such as mode0, mode1, mode2,mode4,mode6 gives good PSNR, high comprssion ratio and low bit rate. Out o f these modes mode2 gives good PSNR, compression ratio and redced bit rate, mode5, mode7 and mode8 gives lower PSNR, low compression ratio and increased bitrate compared to mode0,mode1, mode2, m ode4 and mode6. The simulation results are presente d using Matlab. The PSNR , compressed ratio and bit rate achived for di fferent quantization parameters of mother daughter frames , foreman frames was presented.
