I recently recorded a short tutorial video (not for Blender) using TechSmith SnagIt 11 and wanted to edit and render it in Blender. This works fine except for one thing: After having imported the video into the VSE the colours all look really dull: for instance, what was originally pure white is now #C9C9C9... It's also not just a display issue - it also looks like this when I render the video out again. It does look fine when playing back the original video in VLC.
Here's part of an original frame from source video (left) and (approximately) the same frame as it appears inside Blender 2.79 and after render (right):
Any ideas what could be going on here and how best to fix it (ideally without having to rerecord the original video)?
In case it helps, this is the codec information reported by VLC for the original video:
Codec: H264 - MPEG-4 AVC (part 10) (avc1)
Display resolution: 1280x720
Frame rate: 8.043657
Decoded format: Planar 4:2:0 YUV
