that is not how SAR is used... search this forum for usage..it's pixel aspect ratio..

also there is no need to set a framerate for audio and you can merge audio and video in one run via MP4Box.exe -fps 29.97 -add c:\psp\video.264 -add c:\psp\audio.mp4 c:\psp\output.mp4

@puffpio: about SAR i found: and thats how i tried to use SAR on PSP. Using another resolution than 320x240 is no option for me. So I'm looking further for signaling anamorphic content to PSP. I know its possible, PSPvideo9 doing so too...

SAR is NOT the resolution and its NOT 16:9/4:3 for the correct SAR values for 16:9/4:3 use search

@bond and @Sharktooth: Thats why I edited my post 10 minutes before you wrote to --sar 64:45 based on your FAQ and that including link to: or do I miss something important? --sar 64:45 should be the correct ratio for 16:9 PAL If I use --sar 16:9 then output should be "wider" and not the correct ratio. But when playing on PSP NONE of these both settings change my display output. Thats why I asked, because i thought I missed something, maybe in AtomChange or somewhere.

pso surpports anamorphic 16:9 MP4 playback(for example, 320x240 is displayed as 426*240 in original mode). psp recognizable sar flag is in the special header but not in the video stream. you can edit the MP4 binary as following: address: 00AC-00AF 00 04 00 03 -> 16:9 00 01 00 01 -> 4:3
