| Summary | 0000327: H.264 Encoding of YUV422 files results in a larger file size | ||||
| Description | Hi Everyone, We are comparing Encoding efficiency of H.264 with different Chroma subsampling. We took a video, subsampled to YUV444, set a QP value, performed H.264 encoding. FOr the same video, resampled to YUV422, set QP value same, perforemd H.264 encoding. The file size resulting from YUV 422 Input to H.264 Encoding is much higher than YUV444. It is actually 3 times more and also the PSNR is also very high. For example: Input File: sc_cad_waveform_1920x1080_20_8bit_200_444 YUV444 --------- Bit Rate : 2100 PSNR: 41.1 (AVG) QP: 17 YUV422 ------- Bit Rate : 11000 PSNR: 46.1 QP: 17 Even for equivalent PSNR, YUV422 files were twice as much YUV444 (encoded) | ||||
| Steps To Reproduce | Take any input file: Convert to YUV444/ YUV322 formats Set same parameters except for CHroma Subsampling Compare the encoded files for file size and you will see the difference. | ||||

Are you still encoding your 4:2:2 file as 4:4:4? It seems that you are setting YUVFormat as 3 which is for 4:4:4 material instead of leaving that value at 2. Also, make sure that you are reading the data properly, assuming that the video file is in Packed format instead of Planar (see parameters Interleaved and PixelFormat). |

Has that been resolved by Alexis' comment? If there is no further comment, I'm going to close the ticket. |
