I tried to use megui to create a psp supported video. I got some information which that the video should be less than 480*272 to support PSP. However, this video works on PSP.

http://www.flyupload.com/?fid=7152068


It is told to be 720*480 DAR (16:9) and amazingly it work. I tried to use the profile provided here

http://forum.doom9.org/showthread.php?t=101813&highlight=megui



but the most I can do is 480*272. So how is it possible to do like the video about.

What is the actual term or setting to let mp4AVC support PSP? And how can I convert the video like the above?

Need someone to explain please. Thank you.

for 720x480 DAR 16:9, you should be fine with this setting:

--crf 20 --level 3 --keyint 240 --min-keyint 24 --ref 2 --no-fast-pskip --bframes 3 --b-rdo --bime --weightb --subme 7 --trellis 2 --analyse p8x8,b8x8,i4x4 --me umh --threads auto --thread-input --progress --no-dct-decimate --no-psnr --no-ssim --sar 32:27

key options are:
--level 3
no p4x4
no b-pyramid (causing artifacts)
proper number of reference frames
proper number of b-frames
--sar 32:27 (DAR 16:9)

the behavior of --ref have been changed since rev721, so "--ref 3" may be also working

BTW 720x480 is 480p:)

Thanks,I tried to change the title but in vain.

will this work?

--crf 22 --level 3 --ref 3 --mixed-refs --bframes 2 --b-rdo --bime --weightb --direct auto --subme 6 --trellis 1 --analyse p8x8,b8x8,i4x4 --vbv-bufsize 200 --vbv-maxrate 2000 --me umh --threads auto --thread-input --progress --no-psnr --no-ssim --output "output" "input" --sar 32:27



How can you select a dar option? Through AviSynth or?
