I tried NTSC, PAL, different resolutions (HD or 720) - it was still choppy and jerky.
X265 isn't supported in the trial version, but I tried exporting as XAVC - and it was the same.
The clips look great in the timeline edit, the preview is OK - but the output files are just bad-looking, like a laggy transmission.
I then tried encoding at 120 FPS. It looked better, but with Hitfilm, I exported videos @ 29.97 FPS and they were perfect at half the filesize and no choppiness at all.
I tried this on two different computers, with different hardware (both Nvidia cards, but different types), and the output files from Power Director were always choppy and jerky.
Then I saw this about turning off deblocking: https://www.youtube.com/watch?v=wrJ0s9KmWds
I did that. It helped a little, but not much. There is maybe 10-25% difference, but the output clips are still much worse than the ones made in Hitfilm.
Has anyone run into this? Is there a fix? Or is it done on purpose in the trial version?
