if the video really smooth for u, try lowres=0 to restore the video resolution, lowres quite ugly lol.
sub display works for me though, im not sure coz the mplayer version u using is rc2, while im using the latest svn version.

try play the video again, then press CTRL + M,
copy the entire log, post here.
example:

» Click to show Spoiler - click again to hide... «


anyway, I notice that when the video name is in Japanese/Chinese, it can't play
must rename it to English first
btw, the subtitle is in Chinese... is that the reason that sub cannot be display??

VirtualDubMod can do it for you

You need to reencode the audio to a supportable format for ur DVD player example mp3 (if the ogm files are using Vorbis or others)

how to 'extract' the audio from the ogm ?
can virtualdub do mp3 encoding for me or should i use another software for that?

hehe ..quite noob too .. not familiar with virtualdub on ogm files

whats the diff between full processing, normal recompress, fast recompress and direct stream copy ?
also, i want to do the files in batch ... how? each file have to do manually?

guys, really really need your help icon_question.gif

with the coming of the new year, i've planned to post some videos on youtube. on 1.1.08, i've recorded a video using my Sony Cybershot DSC-T200. The file is .mpg with a size of 126MB. During the recording, I've also recorded separate audio tracks (.wav format) with a size of 60MB each for guitar track & vocals.

i've also created the final video using the Windows Movie Maker and the result is a 126MB video in .wmv format, running approximately 6 mins. when i tried to upload the video in youtube, i was prompted that the file should not be more than 100MB and not more than 10 mins. so, i use WMM again and compressed the file size to 97.3MB, also in .wmv format. when i tried to upload again, it seemed that its taking ages to do so. so, i checked at the youtube's help centre, and found out this:

We recommend the following settings:

* MPEG4 (Divx, Xvid) format
* 640x480 resolution (* most updated recommendation)
* MP3 audio
* 30 frames per second

Resizing your video to these specifications before uploading will help your videos look better on YouTube.

to comply those, what software do i need to use:

1) to convert the .wmv format to MPEG4 with those resolution & 30 fps?
2) to convert the .wav format to MP3?
3) any other simpler way to do so?

thanking u guys in advance for your professional advice. happy new year!!

thanks for the prompt reply! anyway, i've found the converter from wav to mp3, the Xilisoft mp3 wav converter. works fine!

anyway, i've downloaded tha virtualdub. all i can see is there's only one option of saving it into .avi format. what i want is conerting the .wav into mpeg4 as recommended by youtube. how can i do this with virtualdub? sorry, total video noob here.... blush.gif

actually i know how to one shoot transcode ur wmv to divx/avi, but i dont think u even know how to use it, unless u know what its batch file tongue.gif

download xvid, http://tirnanog.fate.jp/mirror/XviD/XviD.cvs.head.MTK.exe
or dixv here http://www.divx.com/
once finished install one of the vfw encoder from above, virtualdub will be able to encoder ur video to the so called mpeg4 video.

if u wish to resize ur video, press CTRL + F, and press ADD button,
and search for resize filter, press the preview button to preview the changed resolution on-the-fly.
explore yourself tongue.gif

open virtualdub, and press F1, that should pop up a virtualdub help documents, although its outdated, but i think that should help alot. virtualdub not that hard to use, just the codec settings are too complicated for new users.

youtube re-encode the audio to 56kbps, 22050hz and mono mp3 iirc, thats why the quality is low, unless they use he-aac.

http://en.wikipedia.org/wiki/Flash_Video

too bad i cant watch the video smoothly sweat.gif connection slow lol.

Added on January 5, 2008, 7:05 pmor try divx stage6, http://www.stage6.com/
it should preserve the audio/video quality if u use the correct settings.

how to balance out between resolution, bit rate, and file size if we want to resize a video?
any tips/rule-of-thumb to do this?

let say i want to resize a file from 350mb to 260mb, what's the best bit rate, resolution, bits/pixel to use so that the quality loss is not too severe?
any tips?

u can try experiemnt with xvid encoder, 2 pass mode with target file size, use high quality settings. after that u can use the bitrate setting form xvid on x264 encoder, but its up to u tongue.gif

i think what usually encoder do is, lower the encoding bitrate,
resize the video resolution is not a good idea because of pixel interpolation will make the video look blurry, or other artifacts.
