Local Recording Settings

Last Updated: Nov 23, 2015 07:34PM HKT
Welcome to the XSplit Workshop, a series where we provide tips to help you get the most out of your broadcast.

This edition will give you an overview of XSplit Broadcaster’s local recording menu, which has changed quite a bit from version 1.2 . We’ve also prepared a video that gives an overview of this guide.

 


Video Encoding

This area determines the quality of the video in your recording. The first option is the codec menu. Here you can select either the X.264 software encoder or Intel’s Quick Sync if it is available on your machine. For more information on hardware encoders please check out our dedicated blog on hardware encoders found here. Please note that hardware encoders will create larger files, but will have decreased CPU usage.

The second option is the quality setting. You can choose from a variety of quality levels from Standard to Ultra High. You also have an option for custom quality settings, but this is only recommended for advanced users. To enter the custom setting menu click on the gear symbol next to the quality selection menu. The graphs below highlight the differences between using X.264 and Quick Sync.

X.264 vs. Quick Sync (Using a 1080p/30FPS 30-second recording for reference)

The graph below shows that the file sizes when using X.264 (software encoder) are about half the size of those using Quick Sync (hardware encoder).

This graph shows how Quick Sync reduces CPU usage at various quality levels.

Audio Encoding

This area determines the quality of the audio in your local recording. The first option is the audio codec, which isn’t quite as complicated as the video codec options. If you have a personal or premium license, you will have access to the AAC LQ & AAC HQ codecs. If you have a free license you will only have access to the Speex codec.

Depending on which audio codec you are using, you will have a variety of choices in the bitrate menu. The higher the bitrate, the better the audio will sound in your recording.

The format menu lists the available sample rates (e.g. 44.1 KHz) and available audio channels (mono or stereo) for your recordings. Speex can only generate mono recordings, whereas AAC can produce both stereo and mono recordings. As with the bitrate, using a higher sample rate and using stereo results in a clearer recording compared to a lower sample rate and only using a mono format.
 

File Output and Other Options

The output area is where you can determine the file type that is output and whether to split the files when you finish a local recording. The options in the file type drop down box will depend on the type of license you have. Those with a personal or premium license will have the option to choose between the FLV and MP4 file types. The MP4 file type is definitely the preferred choice as it easier to playback and edit. The FLV file type tends to require special codecs for playback and needs to be converted to be edited.
 

Picking the MP4 option also allows files to be split at custom file size intervals. Splitting files is quite useful in order to avoid long post processing times with large files and also makes it easier to manage files in video editing software.
 

Finally, the force constant frame rate option is useful for those who wish to use XSplit local recordings in various video editing software (where frame rates of imported videos may vary).
