ok first you will need Megui and K-lite codec installed
maybe you already know that there are not a lot of ps vita Convertibg guide and the 1's that exist are shit/the lowest quality possible on the PSV so im gonna tell you how to go to the max possible on the PSV
1st guide oneclick encoding
1)click 'one click' in the bottom
2)then you get input/output and all basic stuff and on the bottom there's 'show advanced options' click this now there should come 2 new pages (if the video contains multiple tracks then use only 1)
3)then go to 'advance config' choose a working directory(there should be 1 by default but if you want you can make 1 youreself), don't use chapters because PSV doesn't support it.
then there's output resolution (if the input is lower or the same as 1920x1080 (1080p is supported since firmware 2.00) it's fine but if it's higger go to the second guide and the resolution may not be an odd number) just use keep input resolution you can stretch it but it wil only make the video worse.
4)then 'encoder config' here's where a lot of people get stuck.
take 'x264 scratchpad' and click config.
this will show up
first press advanced settings
encoding mode: you can choose from 'const. quality',multiple pass encoding, 'const. quantizer' and ABR you can search for another guide on what each 1 does because it's way to much put in this guide.
here were using crf on 19,0 (a video of 25 min should be around 300mb)
preset: is how fast the encoding will be but don't set it already to ultrafast because high speed=low quality and greater sizes and i realy don't recommend using ultrafast because the video will get realy worse and the size double maybe even triple.(update: don't pick anything lower than 'slow' because the ps vita can't handle it's complexity, medium is the most stable way to encode for ps vita because the slow can sometimes have problemes aswell. )
tuning:default (you can change if you know what your doing)
AVC profile:high profile
AVC level:4.0 is the higest limit you can go (but 3.1 is more stable)
target playback device:default
just leave 'frame type' by default
then go to 'rate control'
just leave everything to default exept for 1 thing VBV buffer size and VBV max bitrate set both on 15000 (you can only choose this if you use const. quality) (update)
use M.E algorithm 'hexagon', M.E range 16 and subpixel refinement you can choose what you want I use 07 but you go higher or lower depending on how much time you have because this makes it longer to encode
just leave misc to default
then press ok and go back to encoder config
now the audio for this we use 'nero scratchpad'
now go to config
choose your preferred decoder (i use nicaudio)
then output channel set this to 'downmix multichannel to stereo'
and sample rate to 'keep original'
the use constan bitrate and use 192 kbit/s (you can go higher or lower but higher won't make much difference while watching the video on Psv, update: for some reason too high audio bitrate makes the ps vita crash or some time refuse to play the video)
and AAC profile 'automatic'
then press ok and go back to 'general'
then press ok
then you go back to the main menu then go to the page 'queue'
there should be 3 jobs in your queue then press start and you done (this can take a while depending on your PC)
2nd guide 'AVS Script'
this guide is for video's higher than 1920x1080 and video's that use external subs (update: ps vita now supports 1080p)
start from the begin meny and press tools and click AVS script creator
page like this will show up
input your video and press directshowsource
now there are 2 things you will do (3 if your just here for the resolution and 4 if your encoding anime)
1)select DAR set it to 16:9 (1,7778)
2)resize: set it to 1920x1080(if the video is lower than 1920x1080 you won't be able to do this if that's the case just leave it to the original resolution, Psv can play any resolution equal or lower than 1920x1080)
3)set source to anime if your encoding anime if not, don't click it
then press save now go to main menu
the avs script should already be loaded if not just input it then use x264 scratpad exact the same as in guide 1 just scroll up
set file format to mp4
now the audio just input it in the audio section on the menu
and use nero AAC scratchpad exact the same as in guide 1 just scroll up
then both the video and audio press queue
now in the 'queue' menu 2 jobs will be there just press start.
after it's done you should get a video file without audio and a audio file.
now open the tools and select muxer and choose mp4 muxer
now put the video without audio in video input and the audio file in audio input leave chapters and subtitles blank
then press queue
now there should be a new job in the queue menu press start.
now it's done now you made a HD PSV video

PS Vita can play MP4s at up to max video bitrate of 1.5Mb/s, and audio of stereo channel with no restriction.
What this means is, for any MKV found on the net that is < 400MB for a single TV episode with run time of 45 minutes, you can simply remux them into MP4, and they will play fine on the Vita. No unnecessary video reencode = no time wasted = more time for gaming.
You want to make sure that the audio is in stereo. If it's in AC3 or DTS 6 channels, then reencode just that track into stereo with your favorite media encoder. For painless muxing of x264 and AAC you can use YAMB.
I'm glad I don't watch foreign cartoons that necessitate hardsubbing and thus reencode. I really wish the Vita would accept SRT or ASS subtitle files.
