the one in my signature. the video of the panther that almost got my puppy was moved to the 4 tb purple driveoh nothing probably just Porn bot scanning your video files.
I used to see that on my old system.
i7-3770, wd Blue 6TB, before substreams.
What hardware/ system are your running BI on?
so I tried copying the file to other drives, still the same when I open it outside of BIDoes that clip play okay before you export it? If so, it is likely that your current BI version is just buggy and can't export to mp4 properly. Try exporting to AVI. AVI has different frame timing mechanics so it might behave differently in this case.
