image artefacts on qtgmc-ing .MTS files

[i4004]

ps2/ i think i'll try some other video compression in meantime

that makes no sense, as issue is there even before compression.....

let me just try using gpu for decoding on this version, because it seems this indeed is video decoding issue, as turing on gpu decoder in video players (for example pot player) seems to solve it. 

nope, still artefacts in the beginning. i'll try new version and report back. 
prediction: i believe small timing issues in the way this camera writes down avc are causing some macroblocks to be dropped by decoders....in some way it has to do with interlacing....
