When you combine two clips, they need to have audio that's the same samplerate.

Samplerate is the rate of samples in an audio clip.

e.g.

CD: 44,000 Hz Sample Rate
DVD: 48,0000 Hz Sample Rate

chances are that one of your clips is 44,000 and the other is 48,000.

SAmple rate is kind of like frame rate for video. You can convert it between 44,000 and 48,000 and it'll sound about the same, or you can just playback 44,000 Hz audio at 48,000 Hz and it'll sound higher pitch and be sped up.

Avisynth has a few built in commands for adjust these:

ResampleAudio is like "Convertfps" and will convert to another sample rate without changing the pitch.
AssumeSampleRate is like "Assumefps" and will simply change the rate at which the samples are played back, causing the audio to speed up or slow down.


Homework Problem:

You have a video file which is 23.976 fps. You want to convert the video file to PAL at 25 fps by using Assumefps, but the audio gets out of sync. How do you use "Resample Audio" and "Assumesamplerate" to fix the audio?

Wait a sec XD I dont got it...

Which order I need to put and where?

here is the tab:

a=DirectShowSource(Video,fps=23.976,convertfps=true)
b=DirectShowSource(Video,fps=23.976,convertfps=true).Trim(2159,33311)
last=a+b
TEXTSUB(Subtitles)
TEXTSUB(Subtitles)

The quality is 704X396..

after the "ResampleAudio" what supposed be?

You kill yourself because you're trying to convert to PAL.

Are you sure the download is complete and went 100% correct?
Does the file play fine in your media player?
Post the exact AviSynth error messages!
Are you using the latest ffmpegsource version? (r580)

I may be in the wrong thread for this, but why the hell not??

Ok, so I made Avisynth script and I'm loading it into virtual dub. I'm trying to apply some filters for sharpening. I heard that the 'General Convolution' filter is better then warp sharp and the regular sharpening filter. If this is true, what values do I need to put into each box to get a sharpen result. Or is there another filter I can download?

Btw the way, the clip I'm filtering is an old episode of One Piece, episode 1 to be exact. Just trying to clean it up a little to watch on my big screen.

don't use virtualdub filters

Also, sharpening an image by applying a general convolution matrix is "better" than sharpening it with warpsharp kinda like how cholera is "better" than the bubonic plague. I strongly advise you start checking the dates on the guides you read; 2002 called, it wanted its shitty filters back.

Well I was obviously in the wrong. So what would you recommend I search/lurk for, for sharpening?

The General Convolution filter is for people who know what a discrete FIR filter is and how to design them.

The question Fluff is asking you is, why do you think you need to sharpen your source at all? Because you most likely don't really.

Because I would like to see an HD version of it on my big screen, but just 'upscaling' isn't all that great. I'm sure I'd have to remaster it to get true HD but I don't have the time for it.

limitedsharpenfaster is still pretty good and easy enough to use, you could start there

You mean make an ARGB video for overlaying from an ASS file?
Yes, VSFilter has an Avisynth function called MaskSub() that will do that.

MaskSub("file.ass", width, height, framerate, framecount).flipvertical()

ARGB32 video in VFW is rather brittle so be careful when encoding it, you can easily lose the alpha channel.

Quote:
MaskSub("file.ass", width, height, framerate, framecount).flipvertical()

Final result

text not clear ?




Quote:
clip1 = AviSource("D:\anime\Persona4 13 ED.avi").ConvertToRGB()
clip2 = AviSource("D:\anime\OverlayFX.avi").ConvertToRGB()

mask_clip = Mask(clip1, clip2.GreyScale.Levels(0, 1, 75, 0, 255))
Overlay(clip1, clip2, mask=ShowAlpha(mask_clip), mode="Blend", opacity=1)
