4k video on HD timeline?

I have been recommended to shoot at 4K even if my final output destination will be standard HD. Mainly because there is more detail to begin with, and I can zoom in to get a closeup without losing quality.

In Premiere they recommend starting a new project with a 1080p timeline and dropping the 4k footage onto it.

Does the same principle apply with Magix? Or is it better to make a 4k project and then just export at HD?

Hi,

Normally if you create file 4K or HD file 1080 the software convert your original clip in proxy file, that means a low quality file to work in your project. When finish it use the project file to compile the final product this is call rendering.

Hi

The rule is it is best to set the project resolution to the resolution you will be export at, that way any titles or effects like sharpness etc that you add will be displayed properly during preview. Also if the project is set to a lower resolution it reduces the load on the GPU and CPU during editing, similar to clicking the "reduce resolution" in the Lightning Bolt button dropdown. If you have a modern reasonably powerful system, you should not need to use Proxies with 4K with the above method.

Excellent, that explains it very well, so I still have all the benefits of 4K source material then.

Yes, as far as reframing to a smaller section goes, but there may be losses when re-encoding from one format and codec to another. Also perhaps longer render times. Your camera would need to be set to a bit rate 4x that of HD to not be applying more compression with the associated losses.

It would probably be best to shoot a test of the same scene at 4K and then HD, and render both to HD to see if there was any difference in the exported file.
