global.bat gets stuck on this line:
".\programs\avs2pipemod" -info encode.avs > ".\temp\info.txt"
The encode.avs file works on VirtualDub; however, the process stays open even after you close the program (so I assume that it, too, hangs). Running avs2pipemod -info ..\encode.avs from the command-line shows the data, but it doesn't close afterwards. However, once I changed the ng_bighalo/FreeSub bits to ng_bighalo only in the avs file, everything worked properly. (Doesn't look too great in the low resolution encodes, though.) I have tested a few different versions of AviSynth (including AviSynthPlus), re-downloaded avs2pipemod 1.1.1 and freesub.dll, and tried 2 different lossless AVI codecs, with no success. Is there any known solution to this (e.g. an alternative to FreeSub that looks good at lower resolutions, a version of AviSynth that is known to Just Work™, etc.)? Although I'm personally only interested in HD encodes at this moment, but I imagine others may have this same issue at some point (if not right now), so if I get this fixed, it may help others later on.

This is a problem with how avs2pipemod and freesub "work" together, and it's quite hard to figure out. Lately I discovered that sometimes it does proceed after freezing on the -info command for a while. If you only need HD, by all means drop freesub, it looks bad at high resolutions.
Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

I'm not so sure that the problem is exclusive to avs2pipemod, because the same happens to VirtualDub - the process stays open after I close the program, if the .avs file uses FreeSub, while that doesn't happen if I remove FreeSub from the equation (here's a video to demonstrate that). In both cases, the program reads the file "normally", but fail to close afterwards. So, I assume that the problem is on how AviSynth and FreeSub interact with each other, probably being a bug on FreeSub itself. But hey, it's just a guess. I'll just not use FreeSub since ng_bighalo works well for me, but let me know if there's any updates on this because I'm curious now ahah, thanks for the reply!
