frame rendering issue
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See

STEPS TO REPRODUCE
1. Load the attached project
2. press play in the editor and watch how you catch a glimpse of a random frame
that is the preceding frame to what I've selected to be shown from the clip.
You won't see it again (at the moment)
3. right-click on the clip in the project bin and tick Proxy Clip. Wait for the
proxy to be generated then press play. You will see it does not do it anymore.
Now, I develop music videos with proxy enabled so I never see these issues at
this stage.
4. Now render the video to mp4-h264/aac Generic HD
5. Watch the rendered video and you will see these frames pop in several times
This issue has been around for years and I've not been able to isolate a clip
for demonstration until now. I get these issues on almost every video that I
render. I normally just spend an hour going through the rendered video and
manually fixing up these errors in the video rendering.
OBSERVED RESULT
A stray preceding frame from the chosen clip is shown.
EXPECTED RESULT
I expect to see in the rendered video what I see in the editor using proxy
clips when developing videos.
