Tracking with upside-down footage

Support Compositing and Post Processing
1

Sometimes I hold my phone the wrong way around and end up with upside-down footage. This is no problem in the video editor and compositor because there are easy options to flip videos.

I can’t see those options in the tracking editor though, and I’m resorting to working upside down as I work on all the tracking shots.

I know I could use Blender to convert the movies from my phone to new right-way-up versions, but this seems like extra time if there is a simple switch orientation option. Is there an efficient way to flip images while in the video tracker?

No. no easy way… if it were me i would use ffmpeg to rotate / flip the video – https://superuser.com/questions/578321/how-to-flip-a-video-180°-vertical-upside-down-with-ffmpeg

blender uses ffmpeg internally to read / write video files.

At the same time as the tracker, could you have a compositor window or VSE window open with the Movie clip loaded and rotated? Might make it easier to reference.

Thanks for your answers. It’s good to know that I haven’t overlooked the feature.

ffmpeg seems to be the fastest approach to correcting the videos, although the attributes and options seem to change from version to version, making online guides and explanations a bit hit & miss. Despite being primarily a linux user for the last fifteen years of so, I found this newbie guide was quite useful for my rusty ffmpeg knowledge: http://linuxers.org/book/export/html/593
