Greetings

Do you know the max 2D DVE scale on a 4K clip if the end product will be shown as HD? Example, a medium wide shot to a close up. What would the scale percentage be before the image breaks up into visible pixels?

Thanks
Vince

That depends on your viewing distance, go close enough and you'll see the pixels evon on unscaled 4K.
Just joking.

Lightworks applies DVE to export resolution which means there is no benefit when using 4K video. When exporting 4K to HD the original is downscaled to 1080p and DVE is applied afterwards. This turns the question into "what are the limits to zoom-in using DVE with HD media".

My view, for high quality demands, don't use it - it will never look as good as a camera zoom.

Zooming/panning using the source resolution of a clip has been submitted as a feature request in the past, but so far, it has not been implemented.

Nope. But there are times when you just have to.

Like khaver, in my opinion you can't really use either of the LW DVE effects for significant enlargement because you can't directly access the media at its native resolution. You will get better results using Boris FX UpRez on the original media or using one of Fusion's 2D or 3D transform effects (also on the original media, NOT an export from Lightworks).

Disappointing. It would serve as a two camera shoot.

Thank you to all
Vince
