How can I convert incompatible media to use in LumaFusion? (iOS)

If you have access to a computer, Handbrake is a free video conversation application that can convert a wide variety of video formats to .mp4 files compatible with LumaFusion. The Handbrake settings we recommend when converting files to edit in LumaFusion are:


Format: MP4 file

Video Encoder: H.264 (x264)

Constant Quality: RF:22

Framerate: 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 2 times 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 have diminishing returns and a larger file size.


Please note that Handbrake is not able to encode in ProRes.
