Trim() does not cut audio together with video.

[jurij]

hi!
i would like to know a workaround for triming audio and video together and keep them in sync.
let's say i have any audio file and a .d2v i can load them both (i can convert the audio to wav and load it in the avs script) but using trim() ith happens that the audio is not trimmed at all.
any solution for this?
i need it to cut commercials out when capturing from SAT TV.
THANX!

Post your script!

OK here's the script:

LoadPlugin("mpeg2dec3.dll")
video = mpeg2source("F:\sw\sw4.d2v")
audio = WavSource("F:\aa MPA T01 DELAY -396ms.wav")
AudioDub(video, audio)
trim(0,7747)+trim(13489,59549)+trim(65055,121630)


The clip is PAL 25 fps
What happens is that @ frame 7747 video is trimmed OK but audio is not exactly trimmed:
@ frame # 7747 (00:05:09)
-video is trimmed ok
-Audio is trimmed but it had a offset delay of -13 seconds
Maybe it's calculated with the wrong frame rate because trim() works with frames while audio is calculated in HH.MM.SS
hope that helped

What happends if you use


trim(0,7747)++trim(13489,59549)++trim(65055,121630)

You should also have a DelayAudio() in there to match the filename, although that alone wouldn't produce sync errors of the magnitude you describe.

i delayed the audio wav in besweet, so it matches right, infact the 1st part before trimming is in sync

I have used:

trim(0,7747)++trim(13489,59549)++trim(65055,121630)

but nothing changed!
Please can you test the trim() function on a PAL movie with a wav source?
Thanx

I've been playing with the trim function today too. I'm having some problems getting it to play nice with the rest of my script, but I know it's something that I'm missing in the readme.

I'm trying to take an episodic DVD, combine the audio and video and then trim out each episode individually. I know it can be done, but every configuration I try brings an AVISynth error.

While I was typing that last reply I figured out my problem! w00t!

I really didn't mean to hijack your thread here... Just got excited ;)
