avisynth + avsmpod stuttering problem?

[ofortunad]

Not sure if this is the right place to be asking but I'm having an issue with avisynth and the avsmpod. The resizer will open and play fine but once I input the code into avsmpod the clip will start suttering and duplicating itself. It's even worse when I try to drag the cursor back because it will then start adding in clips from other timestamps. It's an MP4 file but I don't think that would be the issue because most of the files I use with avisynth are. I use avisynth 2.6. I've tried uncommenting some like it said to but that didn't do anything.

Is there any way to fix this? I've attatched a video of what the outcome looks like and and the avsmpod

LSMASHVideoSource is only frame accurate on a good day. Try LWLibavVideoSource instead. The first time it opens a source there'll probably be a slight delay while it creates an index file.
If LWLibavVideoSource doesn't seem to work correctly, try FFVideoSource from FFMS2. I'm not sure if the latest version has been uploaded to the Avisynth wiki, but you can get it here. https://forum.doom9.org/showthread.php?p=1995165#post1995165
You could also try a newer L-SMASH. https://github.com/HomeOfAviSynthPlusEvolution/L-SMASH-Works/releases

I assume they both still work with Avisynth 2.6. Do you have a good excuse for not using Avisynth+?

Also.... your sample is 59fps rather than the standard 59.94fps. If there's no A/V sync problems you can leave it that way, and it might be due to the issue you're having, but if the the A/V sync is out after encoding you might need to upload a sample of the original MP4 if you need help fixing it.
