Virtualdub Converting help?

[fruitpassion]

I HAVE TRIED ALOT OF VIDEO CONVERTER AND NONE OF THEM SEEMS TO WORK WELL EXCEPT VIRTUALDUB 1.6.19, I have xvid and real alternative installed on my system. Trying to convert rmvb to avi, so i could watch it on my divx player. i tried posting and ask for help and still no one answered my question.

SO HERE IS THE STEPS I HAVE TAKEN
1. Download and install Avisyth, real alternative, virtualdub (not virtualdubmod)
2. open notepad, type DirectShowSource("C:\07.RMVB", fps=29.97, convertfps=true)
Save as 07.AVS in the same folder as the 07.RMVB movie file
3. Open virtualdub and open the 07.AVS file
4. Select video, compression, select xvid MPEG-4 Codec
5. Audio, full processing mode, compression, MPEG Layer-3, 40kBits/s, 24,000 Hz, Stereo
6. File, save processing settings
7. File, save as avi

The movie has a exellent quality (i think it has better than any other converters out there)
but the problem is that the movie freezes around the end and alot of times the audio is not sync with the video?

what should i do? other converters either has bad quality, too slow, or file to big.

I would very appreciate for some answers, thank you very much!

that the movie freezes around the end

That is possibly a sign of using low quality blank dvds. Try different brands. Also try not filling up the disc. Don't max it out and leave your project a little bit under the full size of the disc.

As for the rest I wouldn't know since I don't use real. Good luck.

I would try converting the audio (Audio -> Conversion) to 44.1 Khz, 16 bit stereo and encode as 128 kbps CBR MP3. Many players don't like very low bit and sampling rates.

[fruitpassion]

ok i will try that, i'll get back to you later, and also how do you encode to 128 kbps CBR MP3 and thank you very much

install lame acm

[fruitpassion]

after i installed lame acm, when i tried to open the avs file in virtualdub
it says

avisynth open failure:
DirectShowSource: Could not open as video or audio.

video returned: "Directshowsource: couldn't open file xxxxxx: an operation failed due to a certification failure."

audio returned: "Directshowsource: couldn't open file xxxxxx: an operation failed due to a certification failure

xxxxxxxxxx07.AVS

any help would appreciated!

weird,

perhaps you broke your real directshow filter,

can you open it in mpc?

[fruitpassion]

the failure message has been solved by reinstalling windows xp and real alternative. But its not working at all I tried converting the audio (Audio -> Conversion) to 44.1 Khz, 16 bit stereo and encode as 128 kbps CBR MP3 Video. The audio is still not sync with the video? and the video still freezes around the end, even though the rmvb can play perfectly in windows media player classic. i am really frustrated, and i don't know what to do. any ideas? thanx

[jagabo]

Is the audio off by a constant amount throughout the video or does it start out in sync and slowly drift out?

DirectShowSource("C:\07.RMVB", fps=29.97, convertfps=true)

Are you sure you have the right frame rate?

[fruitpassion]

its out of sync and the video freezes around the end only and i have the right framerate:
DirectShowSource("C:\07.RMVB", fps=29.97, convertfps=true)
and how can you check what the framerate is?

[jagabo]

I understand your audio and video are out of sync. What I'm asking is HOW they are out of sync. Are they off by a constant amount throughout the video? Say one second off at the beginning of the video and still one second off at the end? Or do they start out in sync and get more and more out of sync as the video progresses.

The former is easily fixed by adjusting the Audio Skew in VirtualDub. The latter is indicative of an incorrect frame rate.

i have the right framerate... how can you check what the framerate is?

If you don't know how to determine what the frame rate is, how can you know you have the right rate?

It's hard to get the frame rate of an RMVB file. (RMVB files can be variable frame rate. This is the source of all the difficulties in converting them). I use MPlayer2.exe (the old Windows Media Player 6.4 which still comes with Windows, in the WMP folder). Once the video is playing, right click on the video window and select Properities. Go to the Advanced tab, hilite Video Render, and select Properties. Go to the QUality tab and watch the Average Frame Rate Achieved field. It will bounce around for a while but eventually settle down. This may not work if your system is using a different video renderer (on my computer it's the standard XP renderer, quartz.dll).

[fruitpassion]

its out of sync somewhere in the middle of video, it starts out ok then it gradually out sync at the end. they are off 1 second. i tried to check the framerate like you said and i got average framerate achieved 25.17fps.

and what is audio skew how do you set as?

[yoda313]

if the framerate really is 25fps than it is set up for pal format. You need to have it set to 29.97 for ntsc.

[fruitpassion]

you meann set the DirectShowSource("C:\07.RMVB", fps=29.97, convertfps=true) and then save as avs file then open it in virtualdub if not how do you set to 29.97 for ntsc?

[jagabo]

Just use DirectShowSource("C:\07.RMVB", fps=25.00, convertfps=true). Save as AVI. You're done.

Audio skew simply advances or delays the audio track by the given number of milliseconds. In VirtualDubMPEG2: Audio -> Interleaving -> Delay Audio Track By [ ] ms. Use a positive number to delay the audio track, a negative number to advance it.

[fruitpassion]

have tried a lot of things, but the video is still not sync, i guess i should give up now! *sigh*

[45tripp]

upload it, or a sample rather if you can manage to cut it with real producer

[fruitpassion]

i finally found another way using mediacoder, the converted file plays perfectly, there is no sync issue and it doesn't freeze. Thank You All for Helping!

[fruitpassion]

after using mediacoder, the rmvb plays good and its in snyc, just one small problem is the graphics are very pixalated

This is the settings
Target Format
Container: Default
Video: Xvid
Bitrate: 500 kbps
frame rate : 25.00fps
audio: Lame mp3
audio 64 kbps
estimated size: 152MB

can anyone tell me did i set the settings wrong?

[jagabo]

Use a higher bitrate. If you used CBR encoding use 2-pass VBR encoding intead.

ok well try thats thax
