Importing .tga's as image sequence or still image appears to be vertically mirrored.
Hardware: OS - Windows 7 Ultimate 64 bit
CPU: Intel Core i5 4670k quad core 3.40ghz
GPU: AMD Radeon HD 7800 Series
RAM: 16 GB
Issue: I went to render out some footage out of Source Filmmaker and upon importing the .tga as either image sequences or as a still, I noticed it was mirrored vertically. I checked the actual tga's themselves and noticed they were fine.
Here are some photo's from hitfilm 3 pro and source filmmaker respectivly, with a frame also imported into gimp photo editor to show the exported frame.
How to reproduce: Open up hitfilm 3 pro and under media, click import > image sequence. Navigate to the folder containing images in a sequence using the .tga format and click Select Folder. The images will be constructed as if it was vertically mirrored. Same applies for still image media.
