What is the meaning of Background Rendering? When would I use it?

If you are working on a Full HD Project with many tracks and a number of video effects applied your system may not be performant enough to play your preview in realtime. Also 4K projects can suffer from perfomance in preview.

For such cases ‘Nero Video’ has a special function called ‘Background Rendering‘. With this function enabled Nero Video will render your project in the background whenever your project is idle so that you can even watch complex projects in realtime.

To switch on ‘Background Rendering‘ in ‘Nero Video’ go to ‘options > application settings > editing’ and ‘Enable Nero Background Rendering’.

‘Nero Video’ will show a percentage indication. When this is finished (100%) ‘Nero Video’ is ready for a realtime preview.

How can I preview Nero Video editing projects via Dual Monitor?

If you prefer doing video editing on a laptop it is very useful to have a second larger video monitor for your project preview. This way you also have the advantage of enlarging the project workspace on your laptop.

Make sure your second monitor is attached. In Nero Video click on the dual monitor button underneath the preview screen. Now your preview is shown on the second monitor simulateneaously.

For adjusting the preview quality click on the respective button in the left hand side of navigation bar underneath the preview screen and make use of the quality slider. Select ‘Best Quality’ most right for Full HD preview.

If your system lacks perfomance you can also set the slider more to the left hand side and reduce resolution in favor of having more real time performance.

Finally you can adapt the layout of your main screen to gain more space for your project work.

Your layout will be auto saved with your project and loaded automatically next time you start Nero Video.

How much video can I burn on one DVD? Which settings do I have to select?

This depends on one hand on the type of disc on the other on the video quality (compression rate) you prefer.With standard quality (5073 kbit/s) you can have 2 hours of video onto a DVD-5 (4.38GB).With high quality (8000 kbit/s) you will be able to burn about 1 hour to the same disc.

Quality settings are available in ‘Options > Recording format options’

The Tab ‘General’ lets you select your regional TV standard under ‘Video mode’ to PAL (Europe, etc.) or NTSC (North America, etc.). Per default it is set to be in sync with the language of your operating system. Also ‘SmartEncoding’ is set to ‘automatic’ by default, and we recommend to keep this. So, in a normal case, there is nothing to be set within the tab ‘General’.

TIP: Check Nero KnowHow Glossary if you want to learn more about PAL/NTSC or SmartEncoding.

In the tab ‘DVD-Video’ under ‘Recording format options’ you have ‘Quality settings’ available to select from.

You can also have ‘Nero Video’ compress your quality automatically so that your content fits on one disc. Lots of content on one disc can lead to a high compression resulting in a lower viewing quality, though.In such a case we recommend using a ‘DVD-9 Disc’ (double layer disc with 8.5 GB). This will roughly double the space on your disc and increase recording time based on above mentioned quality levels.For ease of use ‘Nero Video’ has disc format switch that allows hot format switching from within a project’s content screen and within the final burning screen.

1-pass or 2-pass Encoding – Which one is better?

‘Nero Video’ provides two ways of video file encoding as shown in the screenshot: ‘Fast encoding (1-Pass)’ and ‘High Quality (2-Pass )’.

Two pass encoding makes sense if you have used many effects that need to re-render the individual frames from scratch, or if your input and output formats differ a lot. Two pass encoding does a double check to tweak out the last bit of quality. If your input and output formats are more or less identical it is not neccessary to do 2-pass.

Also note that 2-pass encoding takes the double amount of time to finish the encoding.

Moreover ‘Nero Video’ has ‘Nero SmartEncoding’ technology included that helps you save time and quality in case your input and output format are identical. When SmartEncoding jumps in it will not re-render your exported file and save original quality to file.

AVCHD Discs vs Blu-ray Discs – What makes most sense?

For private home videos that won’t last hours – like a commercial movie would – AVCHD discs are the better choice.

AVCHD gives you Full HD quality on a standard DVD disc (red laser burning) while using the disc recording structure of a BD (BDMV). Due to the latter, only a Blu-ray Player can play AVCHD discs.

The good thing about AVCHD discs is that you get the same quality as on a Blu-ray Disc but you will have much less storage space (e.g. 4.7 GB with single layer, or 8.5 GB when using a double layer DVD disc).

As the name indicates a Blu-ray Disc burns via blue laser and has a much higher storage capacity (25 GB or 50 GB) but is more expensive to use.

A cool thing about Nero Video is that you can also create AVCHD structures on hard discs or external flash devices like USB sticks. If your Blu-ray Player has a USB slot – which most have – you can easily play your Full HD AVCHD disc structures with all the menus from the USB stick or USB attached hard disc without even having to burn a disc.
