Think it must have been using MEP 2015 at the time, and I had imported old camcorder recordings that had at the time been saved on VHS. I started cropping them and exporting each short sequence. Well I must admit that I had started this project months ago and thought I would do a quick revisit to finish off for Xmas.
At the time as I progressed, I exported each sequence as a Mpeg file and also saved the sequence as a MEP file. I think since I started the project I have upgraded to MEP 2016 so don't know whether that is causing problems but I cannot seem to open any MEP files in either MEP 2015 or MEP 2016 (it cannot find them) to finally complete this project. Looking at the folder there does seem to be something there but MEP cannot find it. Does anyone have any suggestions please?
