If RawCapConv is crashing on you, here's a quick fix I found on how to salvage video recorded that you made with rawcap

1) Get a 2nd computer OR dual boot a 2nd windows OS
2) Don't install any codecs on the 2nd PC or windows OS
3) Install Dxtory
4) Feed the rawcap files on the 2nd computer and it shouldn't crash.
