 Verify uncompressed video using ffplay before encode to VVENC (important replace video size, otherwise it will not correctly show video, it's like scrambled eggs video):
 ```
-ffplay -i inputtranscode.yuv -s 854x480
+ffplay -i inputtranscode.yuv -video_size 1280x720
 ``` 
 
 Default pixel format of ffplay for yuv and y4m is yuv420p without `-pix_fmt` command.
