Recording to Disk (ISO Recording)

Table of Contents

With the Recording to Disk feature, you can easily record your mimoLive productions to your local disk. This is especially useful for users who want to have a backup of their live streams, or for those who want to edit their videos later. You can choose between various output codecs such as h.264, multiple Apple ProRes variants and HEVC to adjust the quality settings to suit your needs. The feature allows you to start and stop recording at any time, making it easy to create clips for any purposes. Whether you’re a professional broadcaster, a YouTuber, or just starting out, Recording to Disk gives you the flexibility you need to produce high-quality content and share it with your audience.

Recording the program out

mimoLive can be used to record the program output to disk. This is useful for example in the following use cases:

  • Handing off to post production
  • Re-encoding for upload to YouTube, Facebook or any other video platform
  • Archiving a live stream in high quality
  • Record clean video streams of your cameras

Recording various sources simultaneously (ISO Recording)

By enabling ISO Recording in mimoLive, you can capture each input source individually in its original quality. This feature allows you to record multiple sources at the same time, providing numerous benefits such as:

  1. Convenience: Recording multiple sources simultaneously saves time and eliminates the need to record each source separately.
  2. Increased flexibility: Recording multiple sources provides greater flexibility during post-production, as you have more options to choose from when editing the footage.
  3. Better quality: Recording multiple sources can lead to better overall quality, as you can capture different angles, perspectives, and sound sources simultaneously.
  4. Cost-effective: Recording multiple sources simultaneously can be cost-effective, as it reduces the need for additional equipment and crew to capture each source separately.
  5. Improved workflow: Recording multiple sources simultaneously can streamline your workflow, as you can quickly review and edit footage from multiple sources at once.

The File Name field defines the naming format for the automatically created recording files. The final path name with all tokens resolved is displayed below. The following values are available:

  • %document
  • %year
  • %month
  • %day
  • %hour
  • %minute
  • %second
  • %extension

Force the movie container format by specifying the extension!

By default mimoLive will write a QuickTime file with .mov extension. You can force this file format by exchanging the %extension token by the hardcoded extension .mp4 . You also can use the file format M4V by using .m4v as the file extension.

The Video Format menu allows the selection of a video format for the file recording. The following formats are available:

  • Apple ProRes 422
  • Apple ProRes 4444 (includes alpha channel for transparency)
  • Apple ProRes 422 HQ
  • Apple ProRes 422 LT
  • H.264
  • HEVC (macOS 10.13 and newer)

Streaming and Recording Simultaneously – Update macOS 10.13

Update Beginning with macOS 10.13 (High Sierra), Apple has enabled using multiple encoders at the same time. This enables mimoLive to record and stream in H.264 at the same time, making the following warning obsolete. Prior to macOS 10.13 If you plan to live stream while recording, do not choose H.264 as the recording’s video format. If there is an H.264 hardware encoder on your Mac, mimoLive will use it. However, it can only encode one video at a time, so that trying to simultaneously encode recording and stream with H.264 will lead to performance issues. Use ProRes 422 instead as this encoder is quite easy on the CPU and leaves the H.264 hardware encoder free to encode the live stream.

The Audio Format menu allows the selection of an audio format for the file recording. The following formats are available:

  • Linear PCM
  • ACC

Monitoring Live Performance

Once the Output Destination was toggled live its settings view is replaced by a status view displaying performance data in realtime. Refer to Monitoring Performance for details on performance monitoring in mimoLive.
