avspmod - use variables across tabs

[maudit]

hi,
I'm working on a mux beetween a dvd and a webdl fullhd.
the final result must have the webdl for the video and the audio from the dvd.
the webrip contains extra scenes which do not appear in the dvd..
so I've created a variable containing the extra clip, and I try to use it in another tab,
but I receive the message that avspmod doesn't knwn what "VARIABLENAME" means.

I'm using 3 tabs, the first for the webdl, the 2nd for the dvd and a stackvertical tab where i can see audio/video sync.


WEBDL script:

VideoWeb=FFVideoSource("C:\PATH\.WEBRip.mkv", fpsnum=24000, fpsden=1001, threads=1)
AudioWeb=FFAudioSource("C:\PATH,1)

WEBFull=AudioDub(VideoWeb, AudioWeb)

WEBAV1=Trim(WEBFull,19413,19599).Spline36Resize(706,388).Waveform(window=4, zoom=8, under=true)

DVD script:

VideoDVD=FFVideoSource("C:\PATH\C1_t00.mk.mkv", fpsnum=25, fpsden=1, threads=1)
AudioDVD=FFAudioSource("C:\PATH\C1_t00.mkv",1)

AudioDub(VideoDVD, AudioDVD).AssumeFPS(24000,1001,sync_audio=true).Spline36Resize(706,388)

Loop(0,0,573)
Loop(0,605,605)
Loop(2,3247,3247)
Loop(2,3852,3853).Loop(2,3855,3855)
Loop(2,4105,4105)

DVD1=Trim(0,19412)
DVD2=Trim(19413,0)
Final=DVD1++WEBAV1++DVD2

The error is "I don't know what WEBAV1 means."

so, I will probably get some other problems about the audio has not the same bitrate or something,
but for the moment, how do I use that variable coming from another tab?

[jagabo]

You can't use one script's variables in another script.

[VoodooFX]

You can't share variables across tabs, just use one tab:

# WEBDL script:
VideoWeb=FFVideoSource("C:\PATH\.WEBRip.mkv", fpsnum=24000, fpsden=1001, threads=1)
AudioWeb=FFAudioSource("C:\PATH,1)

WEBFull=AudioDub(VideoWeb, AudioWeb)

WEBAV1=Trim(WEBFull,19413,19599).Spline36Resize(706,388).Waveform(window=4, zoom=8, under=true)


# DVD script:
VideoDVD=FFVideoSource("C:\PATH\C1_t00.mk.mkv", fpsnum=25, fpsden=1, threads=1)
AudioDVD=FFAudioSource("C:\PATH\C1_t00.mkv",1)

AudioDub(VideoDVD, AudioDVD).AssumeFPS(24000,1001,sync_audio=true).Spline36Resize(706,388)

Loop(0,0,573)
Loop(0,605,605)

DVD1=Trim(0,19412)
DVD2=Trim(19413,0)
Final=DVD1++WEBAV1++DVD2

ok thx , i got it, but now, using this script:

there's another error regarding audio, it says:
Splice: The audio of the two clips have different samplerate! Use SSRC()/ResampleAudio()



this is the audio of the webdl:

can i join them? how do I fix the webdl audio?

[VoodooFX]

You are changing the sample rate of DVD here: "AssumeFPS(24000,1001,sync_audio=true)", the sample rate must be same to join.

[maudit]

You are changing the sample rate of DVD here: "AssumeFPS(24000,1001,sync_audio=true)", the sample rate must be same to join.

ok fine, if I remove the "sync_audio=true", I can join them, but this way the audio will desync...
ok maybe I'll fix it at the end.. let's see i f I can continue with the video sync now..

[jagabo]

It told you what to do: " Use SSRC()/ResampleAudio()"

[maudit]

It told you what to do: " Use SSRC()/ResampleAudio()"
http://avisynth.nl/index.php/SSRC
http://avisynth.nl/index.php/ResampleAudio

I see but I'm in difficult with them. Never used before.
Tried both, SSRC gives me this error: https://www.dropbox.com/s/bl2hihpd98qss2t/SSRC.png?dl=0
ResampleAudio, just do nothing: https://www.dropbox.com/s/kh8i87igeb161yw/Resample%20Audio.png?dl=0

can I please have a bit of help understanding what command to use of those two, and how to use it?

and why, the line "AssumeFPS(24000,1001,sync_audio=true)" changes the samplerate from 48000 to 46034?

[davexnet]

Something like this

AssumeFPS("ntsc_film", sync_audio=true).ResampleAudio(48000)

[jagabo]

and why, the line "AssumeFPS(24000,1001,sync_audio=true)" changes the samplerate from 48000 to 46034?

Because that keeps all the audio samples intact. You slowed the video by changing how long each frame is displayed (with no other changes to the frames). And you slowed the audio by changing how long each sample is played (with no other changes to the samples). Ie, both are lossless transitions.

[maudit]

Something like this

AssumeFPS("ntsc_film", sync_audio=true).ResampleAudio(48000)

thank you all, that works.
SSRC gives me the same previous error or maybe I don't know the correct syntax.

just one thing: the audio loses sync progressively during the whole film.
at the end of the film (frame 144692), the audio shift by about 4 or 5 ms.
audio comparison 25p vs 23976.
https://www.dropbox.com/sh/h6u260pii9yajpb/AAD-8WpyfNezk4KRYwoZSE__a?dl=0

it is not a bug issue, but i would like to understand: this progressive unsync is made by some floting point errors made during the Resample?
using SSRC can make it better? I mean without the progressive 4ms desync?

I'm also wondering if it isn't better to make the mux at 25, using the sync_audio=true, and resample on the webrip parts..
in order to avoid the desync.
edit: I did it and audio sync is now perfect, but in this way for english audio,
I have to use the AC3 192 DVD audio which needs the same script process or better use usac3to to strecth the WebRip E-AC3 224.
uhm.. the best should be to keep all at 23.976 with original eng audio and ita audio processed in this script but without that 4ms desync...

at the end of the film (frame 144692), the audio shift by about 4 or 5 ms.

Less than ~150 ms shift is unnoticeable. Better worry about the audio pitch.
Btw, the original DVD audio may have the incorrect pitch.

I would do like this:

# If audio has the correct pitch:
VideoDVD=FFVideoSource("C:\Users\antip\Desktop\Cittadino X (Gerolmo, 1995)\makemkv\C1_t00_track1_[eng].mkv", fpsnum=25, fpsden=1, threads=1).AssumeFPS(24000,1001)
AudioDVD=FFAudioSource("C:\Users\antip\Desktop\Cittadino X (Gerolmo, 1995)\makemkv\C1_t00.mkv",1).TimeStretch(tempo=(96.0/1.001))

# If audio has the incorrect pitch:
VideoDVD=FFVideoSource("C:\Users\antip\Desktop\Cittadino X (Gerolmo, 1995)\makemkv\C1_t00_track1_[eng].mkv", fpsnum=25, fpsden=1, threads=1).AssumeFPS(24000,1001)
AudioDVD=FFAudioSource("C:\Users\antip\Desktop\Cittadino X (Gerolmo, 1995)\makemkv\C1_t00.mkv",1).SSRC(Round((48000*1001.0)/960.0)).AssumeSampleRate(48000)

I'm also wondering if it isn't better to make the mux at 25, using the sync_audio=true, and resample on the webrip parts..

Not in this case as 25 FPS is not correct FPS for this film, it's 4% speed up.

SSRC gives me the same previous error

It doesn't work on all samplerates, usually it is used for 44100↔48000 conversions.

[jagabo]

at the end of the film (frame 144692), the audio shift by about 4 or 5 ms.

Less than ~150 ms shift is unnoticeable.

And note that 1 frame at 23.976 fps is 41.7 ms. So 4 ms is about 1/10 of a frame. There is no way you could see/hear that.

[VoodooFX]

using SSRC can make it better?

In theory - yes, I dunno if it's audible in practice, I've never used ResampleAudio().

[maudit]

thx all, it worked as expected.
I made 2 versions, one with ita-eng dvd audio at 25p, for ita users.
the other with the webrip untouched plus ita audio at 23.976, just by change position at these few lines:
AssumeFPS(), sync_audio=true and ResampleAudio().
Also used Amplify(0.6) to have smoother audio joints.

all audio tracks are in sync at ms level.
