using this effect makes video editing laggy. Is there a way to majorly optimize this? its an effect all youtubers use, and it will be excellent if optimized somehow
Hello, this filter is in comparison to other filters indeed fast. If your PC is too slow you have to use proxy files with lower resolution or you simply limit the player resolution to something like 540p.
Rotate and Size GPU filter with GPU Effects is faster if you only need to rotate by multiples of 90 degrees using Properties > Rotation. You can still use the CPU filter for rare occasion to use arbitrary rotation. But GPU Effects also needs proxy and preview scaling if you using high resolution and/or frame rate.
