This is similar to https:*developer.blender.org/T78200 but itis not answered in https:*developer.blender.org/T77669.

The code is:

- !/usr/bin/env python
- -*- coding: utf-8 -*-

import bpy
import os
import sys

s = bpy.context.scene
sed = s.sequence_editor
sequences = sed.sequences
vse = s.sequence_editor

event_ID = sys.argv[8]
event = str(event_ID)
print("event_ID = " + event_ID)

pathout = "/var/www/html/data/event"
    
#Declare arrays#
fileOut =[] * 5
fileOut.append("")
    
#Read in voiceovers#
fileOut.append("/var/www/html/data/event1/event1-1.wav")
fileOut.append("/var/www/html/data/event1/event1-2.wav")
fileOut.append("/var/www/html/data/event1/event1-3.wav")
fileOut.append("/var/www/html/data/event1/event1-4.wav")

#Include frames per voiceover# 
vLen1 = 187
print(fileOut[1] + ' length in frames = ' + str(vLen1))

vLen2 = 254
print(fileOut[2] + ' length in frames = ' + str(vLen2))

vLen3 = 333
print(fileOut[3] + ' length in frames = ' + str(vLen3))

vLen4 = 367
print(fileOut[4] + ' length in frames = ' + str(vLen4))

#change voice overs
s1 = fileOut[1]
frame_start1 = 1
frame_end1 = frame_start1+vLen1+9
sound_strip1 = sequences.new_sound("Sound1", s1, 2, frame_start1)
sound_strip1.frame_final_end = frame_end1
print("frame_start1 = " + str(frame_start1))
print("frame_end1 = " + str(frame_end1))

s2 = fileOut[2]
frame_start2 = frame_end1+1
frame_end2 = frame_start2+vLen2+9
sound_strip2 = sequences.new_sound("Sound2", s2, 3, frame_start2)
sound_strip2.frame_final_end = frame_end2
print("frame_start2 = " + str(frame_start2))
print("frame_end2 = " + str(frame_end2))

s3 = fileOut[3]
frame_start3 = frame_end2+1
frame_end3 = frame_start3+vLen3+9
sound_strip3 = sequences.new_sound("Sound3", s3, 4, frame_start3)
sound_strip3.frame_final_end = frame_end3
print("frame_start3 = " + str(frame_start3))
print("frame_end3 = " + str(frame_end3))

s4 = fileOut[4]
frame_start4 = frame_end3+1
frame_end4 = frame_start4+vLen4+9
sound_strip4 = sequences.new_sound("Sound4", s4, 5, frame_start4)
sound_strip4.frame_final_end = frame_end4
print("frame_start4 = " + str(frame_start4))
print("frame_end4 = " + str(frame_end4))

renderout = pathout + event + "/vid" + "-" + event + ".m4v"
print("renderout = " + renderout)

bpy.context.scene.render.image_settings.file_format = 'FFMPEG'
bpy.context.scene.render.filepath = renderout
bpy.ops.render.render(animation=True)

sequences.remove(sound_strip1)
sequences.remove(sound_strip2)
sequences.remove(sound_strip3)
sequences.remove(sound_strip4)

Based on https://developer.blender.org/T77669 I changed the sound strips to 2, 3, 4, and 5 instead of putting everything into sound strip 2.

I still get the following when I run the Python script:

Blender 2.83.3

Aborted (core dumped)

This is done strictly by a script, not using the GUI. The strip is not being copied and pasted. I am adding four separate strips through the Python script.

Just as a test I added the strips in reverse order. I got the same results.

Why am I getting the error? And more important, how do I make this work?

SOLVED!!!

All I had to do was add:

bpy.context.scene.frame_end = frame_end4-1
