Issue in Video when giving effects to multiple videos using FFMPEG

I am facing issue when giving effects to multiple video using FFMPEG using script below:

ffmpeg -i Episode10_2952.mp4 -i Episode10_3507.mp4 -i Episode10_RmvAdVi_1_5645.mp4 -i Episode10_RmvAdVi_1_9226.mp4 -i Episode10_3507-5.mp4 -filter_complex \
"[0][1]xfade=transition=fade:duration=0.5:offset=8.07[V01]; \
 [V01][2]xfade=transition=fade:duration=0.5:offset=16.81[V02]; \
 [V02][3]xfade=transition=fade:duration=0.5:offset=16.58[V03]; \
 [V03][4]xfade=transition=fade:duration=0.5:offset=26.42,format=yuv420p[video]; \
 [0:a][1:a]acrossfade=d=0.5:c1=tri:c2=tri[A01]; \
 [A01][2:a]acrossfade=d=0.5:c1=tri:c2=tri[A02]; \
 [A02][3:a]acrossfade=d=0.5:c1=tri:c2=tri[A03]; \
 [A03][4:a]acrossfade=d=0.5:c1=tri:c2=tri[audio]" \
-map "[video]" -map "[audio]" -movflags +faststart out.mp4

I am facing following issues:

1.) Video size is 09:50 2.) Audio of video is completlty out of sync 3.) I am not seeing any effect produced

Logs are available here:

FFmpeg version details are available here https://drive.google.com/file/d/1JLuwJRrtsgtmGLuSj3oQUYWJvkZBu8gn/view?usp=sharing

Offset value coming for 3rd video is 16.58, which is less than second one. Is this ok? If not what is the solution in this case?

Also, I have used bigger image inspite of this video. Still I am facing the issue I mentioned.

Please advise.

Kind Regards,

Your inputs are minutes long, but your xfade offsets are just seconds long.

For example, your first xfade should be offset=537.07 or offset=00\\\:08\\\:57.07.
