How can I convert unsupported media? (iOS)
Video converters can be used to transcode incompatible media for use in LumaFusion. These are available online or in the App Store, but if you have access to a computer, we recommend the free video converter Handbrake. You can find the recommended conversion settings below:
- Format: MP4 file
- Video Encoder: H.264 (x264)
- Constant Quality: RF:22
- Frame Rate: Same as source (constant frame rate selected)
- Encoder Options:
- Preset: Medium
- Tune: None
- Profile: Main or High
- Level: 3.1
- Additional Options: keyint=60
You'll need to type in the keyint=60 into the Additional Options text field. The actual value should be around 2x the frame rate of the video (so, keyint=50 for a 25fps file). This will create a keyframe every 2 seconds, making seeking much better on iOS and in LumaFusion. You could also set to around 1 second (keyint=30 or keyint=25) for even better seeking, but it seems to have diminishing returns and a larger file size.
