The sync issues I have is videofile related and not because I play them on my J3. But it differs depending on what input video I use and since it takes long time to convert them, I haven't checked which specific format is causing trouble. I can tell that it mostly is DVD's that suffers under the problem, but all DVD's I've converted with DVDFab+DVD2AVI+AviSynth+FormatFactory has been clean from any bugs so far.

Another issue I have with SUPER is the sound quality I get. It doesn't matter what input sound format it is, every video I convert to H.264/mp3 has issues. Here is two examples, sorry for the large file sizes:

[Problem Solved]

Could you try listen to them both? I would like to know if it's just me or the sound really is worse in the converted version of Grass. Here is the settings I used with SUPER and here is the info related to the original (input) video file.

Give me some time to check that.
Meanwhile you checked the sample in my previous post.
The audio is @128kbps ,load in your J3 and see/hear quality.

The sound is clearly distorted/clipping on that transcoded video. Make sure you have "adjust the encode volume" in "other opts" in SUPER turned off. This certainly isn't regular behavior, I never had a file starting to clip when transcoding with SUPER.

Thanks for testing it dfkt. And you were right, it was due to the "adjust the encode volume" was turned on with +10db that the mp3 audio was distorted. Thanks for testing it out.

As I still have issues with converting DVD's through SUPER I'll continue on the promised tutorial. Hopefully finished by tomorrow.

I was aware of volume option,still,with the given file I experienced stutter in result.
With format factory(xvid) the result is much fine but double the size of H264 file.

here is xvid sample

Edit:@Uren : I am using SUPER for reason that I am getting same quality(as of xvid) with lesser file size.
As I have suggested in earlier post that use Join Vob tool to get 1 .vob file(for main movie)from DVD.
I have converted 4 DVD9 with these 2 programs and results are painless.
Other option is format factory that directly converts DVD or Video_TS folder but H264 files are not compatible with J3 so one has to stick with Xvid which means bigger file size.
I do not want to encode single movie twice.

I haven't had any problems creating working MP4 files (H264/AAC LC) with SUPER. The only surprises are that it would work at 640x360, and according to that stats file it's also Level 3.

I will have a play around with some stuff to check supported resolution/level/etc, but otherwise, if you want to create an MP4 (H264/AAC LC) file it should work fine as long as you follow the other instructions in the guide (except you use FFMPEG)

The only problem I have noticed with MP4 files so far, is that for the same bitrate, SUPER does not produce them at as good a quality as AVI. This is obviously related to the way that it does the encode, not any specifics of the container. Interestingly, it appears to do a 2-pass! Because of the poorer quality though, I would not reccomend using MP4 at the moment.

I tried recreating those settings with SUPER/FFMPEG, but it doesn't work. With an MP4 container one can't choose Mencoder in SUPER, so I guess one has to look for another tool for working MP4 encodes.

I have tested upto level 3.2(though not required for small resolution 480 x 272) but clip playing fine on J3.
However H264 .avi files from Format factory are not working.
The quality I am getting is at par with avi(encoded with format factory) though file size is reduced.

I can only confirm that H264 videos in .mp4 container produced by SUPER is of sub-optimal quality.
Only .avi container is producing smooth videos.
I have emcoded H264 .mp4 videos from Mediacoder,Nero and other softwares, non are working on J3.
It is our luck that J3 supports H264 in.avi format.

great tutorial! thx

i've just one problem:
when i'm coding movies with an aspect ratio of 21:9 (2.35-2.40) the cowon j3 zooms it to 16:9. is there any way to avoid this?

It's hard to explain since the J3 speaks "icon" in its interface instead of English or German, but you have to click the second icon from the left in the video screen's top bar, then the upper left one in the menu that follows, then play around with the four bottom icons until you got the aspect right.

thanks but i already found this option and it didn't help. all buttons do nothing except the 4:3 aspect ratio. i've tested it with some 21:9 files encoded following this tutorial with super.

EDIT:
maybe i found the mistake: in super the "stretch it" box under options is checked and i can't uncheck it. any idea?

Weird. I did transcode some 1:2.35 Cinemascope stuff for the J3 as well with SUPER, and it displayed just fine.

i've deactivate the "strech it" option. it didn't work.
i also checked the files with mediainfo an it says still 2.35:1 and when i play the file on my pc the aspect ratio is correct and the black bars are back.
weird!

There are some problems with SUPER like if a .vob file has 5 audio languages then I do not know if I am making correct choice of audio.
The integrated Mplayer is crap.
The trail mode(where we can choose some beginning for trial is not working for me.
Format factory is better in this regard and xvid video are working perfectly fine on J3.

here is the solution for my problem:
16/9
1,77

480/272
1,77

21/9
2,33

480/206
2,33

so i render movies with an aspect ratio of 2.40:1 (21:9) with 480x206 and then i get the correct aspect ratio with the j3.

I just wanted to add that any h264 encode looks the best when the width and height are divisible by 16. For example, for a standard 1:2.35 Cinemascope movie, I used a resolution of 480x208 (a height of 204 would be closer to the original aspect ratio, but isn't divisible by 16).

1:2.35 = 480x208
16:9 = 480x272
4:3 = 368x272
interesting and what is the reason for that?

Without going into the highly technical details of the H.264/MPEG-4 AVC standard or how video compression works, here is a somewhat simplistic analysis:
"..it's slightly better to have dimensions divisible by 16, but only because H.264 divides up a picture into 16x16 blocks and if you have a partial block it still has to expend time and bandwidth on it.

A size that is an exact multiple of 16 H & V will compress a tiny bit more efficiently, or look slightly better at the same bitrate."
