Cleaning old 640x480 AVI clips

[Al74]

I am looking into it.

The same happens when I activate Vapoursynth preview of the clip or remove one of the filters in Filter Queue/Order. By the way, when I remove all DeHalo filters, and would like just to use QTGMC, or in general when I try to change filter order. So in each case I have to click ok to move on. So far it has only happened in the case of DeHalo filter.
