D2video converter (simple, drag-and-drop)

MaxSt · 07-25-2007, 14:34

1) Unzip the D2video.zip archive.
2) Put mencoder.exe in the same folder as as D2video.exe
3) To convert a video, drag-and-drop it into D2video.exe

In case you don't know where to find mplayer/mencoder, the official build for windows is here (no GUI).
Or you can try one of more current (and optimized) builds here.

Are there any syncing issues?

elviselvis · 07-26-2007, 04:05

nice thanks

Can you publish how it works (command line commands)?
I`m also interested in mencoder, but mencoder`s command are sometimes tricky so every information is good. Bye

daniel6226 · 08-06-2007, 07:34

thank you! you really saved me! now i can put movies on my cowon.
thank you veryyyyy much!!

wokao118 · 08-06-2007, 16:43

very nice, thanks a lot!!! but just woundering if cowon d2 support mp4 coding and if you have one version for mp4...

jeremyblank · 08-08-2007, 02:31

couldn't find an mencoder.exe in those links. can you send a direct zip please.
Thanks

100 downloads, not enough feedback.

testing it now. few things straight off, there's no quality setting, resize filter setting, nor progress indicator. After this i'll compare it speed wise to ffmpeg+avisynth.

EDIT: took about 6 minutes on the sample video i gave it, and it's rubbish. The quality is good, but it was only 1 pass, it's synched on the pc, but it got cropped from 2.25:1 to 4:3, which will not do. Change this, please. Do not crop, resize only.

testing with ffmpeg now.

EDIT #2: took 11 minutes with ffmpeg, but that did do 2 passes, and did not crop, as you can fully customize it.

I'll now test both files as to sync issues.

EDIT #3: synch is good.

final recommendations: make it 2 pass, add an option to either crop or resize only, option to choose bitrate (350, 500, 700 for instance). Otherwise, nice mencoder "interface", does away with the hassle of commandline.

MaxSt · 08-13-2007, 00:07

There are lots of options exist, just nobody cares to ask about them... Look in the D2video.ini file and you'll see the BITRATE option, for example.

For widescreen source videos, PADDING=32 option is good, it will add black borders of size 32, so there is less cropping. Or use PADDING=AUTO for no cropping, but keep in mind that for very widescreen videos the black borders will become uncomfortably big.

Examples of some other options:

Code:

CUT_TOP=80
CUT_BOTTOM=80
CUT_LEFT=8
CUT_RIGHT=8

START=0:30
DURATION=21:00

IceBone · 08-13-2007, 03:09

If there actually was D2video.ini file, maybe people would ask.

And i don't understand why people want to add black borders... the D2 plays movies just as well without them, like a normal dvd player on a 4:3 tv. :S

It is normal, people only giving feedback when is something wrong ... trust me i have my own experiences with similar application

I tested it only once (before a month) to find out how it using the mencoder to get videos without async, but it don`t have any kind of logging, so i wasn`t succesful.
But it think it will have some async (at least static) for some videos (MPEG-2 from TV is usualy problem), because mencoder have broken muxing (even autors saying it). I have experieces that only if you using external applications for muxing then it is ok. But unfortunately i can`t find the video which has that problem, all mpeg2 which i tested are ok, so maybe you solve it

.

It has async problem with flash videos from youtube.com, for example this
http://www.jakubsloup.cz/Truth_about...uslim_lady.flv
but i wrote to the mencoder bug report, and they said me that it is bug of mencoder, so it not your problem. FFmpeg dont have this problem with this video, it is only mencoder problem, because mencoder don`t using timestamps and ffmpeg yes.

note: do not use 2pass, because quantizer is better; only reason why is 2pass used is because you can exactly set the size of final video (it is good if want to fit it exacly to size of cd, dvd...)

note 2: I saw that it is using xvid as codec, do you know that it dont have any kind of maximal bitrate limit? Only libavcodec mpeg-4 codec in mencoder have maximal bitrate limit. But i dont think it is big problem because i tested d2 that it can handle 3800 kbps without problems (presharpened HDTV video, lancoz 10 tapes scaler, and quantizer = 1) at full 25 fps.

It's better to use 2 pass, because it adjusts the bitrate according to the "action" in the video, and therefore you can get a lot smaller/better quality encode than with just qt (i've been encoding dvds for a long time now, i know).

elviselvis · 08-13-2007, 04:53

I compared 2 pass and quantizer, not 2 pass and constant bitrate. Quantizer doing the same as you said, but without any delay in the changing of bitrate(2 pass have delay, because it save complexity of video for example from 5 seconds sections, but quanitizer count comlexity for each frame personally (better), for example when scene change from slow to fast then with quantizer you dont have any pixelation at the begining, and with 2 pass you have, because 2 pass average bitrate from slow and fast scene, and it give the right bitrate to the fast scene with 5 seconds delay)

IceBone · 08-13-2007, 05:17

No, the purpose of 2 pass encode is to optimise the quality as much as possible, the bitrate is constantly variable, not just averaged, with quantitizer you can never get the proper balance between size and quality. I've done tests where a video with qt 2 was about 5x larger than 2 pass and there was no difference in quality.

elviselvis · 08-13-2007, 05:27

2 pass will always fail in these two extremes (for example with this settings for 2 pass [average bitrate = 1000kbps, max bitrate = 2000 kbps] and this for quantizer [quantizer = 3, max bitrate = 2000 kbps] (it is D2 theoretical maximum)):

1) you have extremely low complex video, quanizer it will give it bitrate 20 kbps for whole lenght but 2 pass give it 1000 kbps
result: both video looks the same, 2 pass give it extremely high bitrate which is useles in this case, it can`t give less, because in 2 pass you always set average bitrate, which always have to be spent

2) you have extremely high complex video, quantizer it will give it bitrate 2000 kbps, but 2 pass give it only 1000 kbps, because 2 pass it cant give more,

as you see average bitrate (2 pass) is nonsense, important is quality (quantizer)

sorry for me is 2 pass masochism techinique, you don`t have any proove that output will not be pixelated
