[Avisynth] How to concatenate multiple audio/video files?

[marcorocchini]

Hi but sorry I'm_a_cAt

please I wonder

is there a way to concatenate more .mxf files

C0001.mxf
C0002.mxf
C0003.mxf
C0004.mxf
C0005.mxf
C0006.mxf
C0007.mxf
...
and so on

so that a unique .avs open all thsi .mxf files with the audio part of each file?

thanks

ps: if a .mxf file does not have the audio part, avisynth should put a silence in audio but the sync audio/video for each file have to be keep, thanks

file1 = SOURCEFILTER("C0001.mxf") #replace "SOURCEFILTER" with the source filter of your choice
file2 = SOURCEFILTER("C0002.mxf")
file3 = SOURCEFILTER("C0003.mxf")
file1++file2++file3

Note that you can run into memory problems because more source filters = more RAM needed. So you may need to append them before loading them in AviSynth. (Using ffmpeg/fmbc?)

SetMemoryMax(16)
LoadPlugin("v:\automazioneclip\avisynth\plugins\LSMASHSource.dll")
file1 = LWLibavVideoSource("W:\brisighella\C0060.MXF") 
file2 = LWLibavVideoSource("W:\brisighella\C0061.MXF")
file3 = LWLibavVideoSource("W:\brisighella\C0062.MXF")
file1++file2++file3

mmmm yes I have try this but there is no audio :=(

mmmmmmmmmmm

SetMemoryMax(16)
LoadPlugin("v:\automazioneclip\avisynth\plugins\LSMASHSource.dll")

videofile1 = LWLibavVideoSource("W:\brisighella\C0060.MXF")
audiofile1 = LWLibavAudioSource("W:\brisighella\C0060.MXF")
file1 = audiodub(videofile1,audiofile1)

videofile2 = LWLibavVideoSource("W:\brisighella\C0061.MXF")
audiofile2 = LWLibavAudioSource("W:\brisighella\C0061.MXF")
file2 = audiodub(videofile2,audiofile2)

videofile3 = LWLibavVideoSource("W:\brisighella\C0062.MXF")
audiofile3 = LWLibavAudioSource("W:\brisighella\C0062.MXF")
file3 = audiodub(videofile3,audiofile3)

file1++file2++file3

can I tell to avisynth:

if the videofile or audiofile part does not have video (or audio) part, please insert black (video) or silence into the gap?

There are functions to create black video and silence. I'm sure it's possible to make it a bit automatic but I'm too lazy to give you an example. Try a search.
