Media Encoder Crash when transcoding an avi file

[HardyHKW]

Hi,

I have a problem handling avi Files in Premiere. I record livestreams out of Livestream Studio in the Higest quality possible. the software generates an avi file then. but when I import this file to Premiere there are lots of error frames in it (sound noises and green screen isues). When playing these Files from the VLC player everithing is fine. So I tryed to transcode these avi s to a different format eg. Apple Prores but wehn I start the encoder the meory of my system Harddrive is going constandly down until it reachs about 80GB left and the I receive the message Yor system has no Memory left you´ll hav to quit the aplication. has anyone any idea hoew to handle this? 

Thanks Hardy
