Recording Audio in FiLMiC Pro
FiLMiC Pro supports audio capture using any of the iPhone’s internal microphones as well as external 3.5mm and compatible lightning microphones.
Audio settings can be configured under Settings > Audio. Here you can specify the input source and recording format and sample rate. FiLMiC Pro will use 48kHz by default as it is the standard sample rate for video production.
The audio input gain slider is integrated into the Time Code Medallion on non-notched devices — and into the full height audio meter on notched devices — and can be adjusted by dragging the white line in combination with the VU meter in order to set correct levels.
For best results, we recommend recording a guide track using the iPhone’s internal microphone, and using a dedicated external audio recorder/microphone for your main audio.
FiLMiC Pro supports most wired external mics, but it may require an adapter or two to work properly. If your phone's 3.5mm plug isn't TRRS, then you'll need to get a TRS-to-TRRS adapter. All smartphones require 3.5mm TRRS plugs instead of 3.5mm TRS plugs, and they look very similar so it's easy to mistake them for each other and it's even easier not to know that there's a difference! The easiest way to tell the difference between TRS and TRRS is by counting the black lines on the plug. TRRS plugs have 3 black lines, while TRS only have two, like in this image:
Check your mic's plug and if it's TRS, you'll need to get a TRS-to-TRRS adapter. They are not too expensive and pretty commonly available. Here's an example of one from Røde: http://www.rode.com/accessories/sc4.
You can find other versions just by searching for "TRS to TRRS adapter." Please also make sure that you are plugging the TRRS end (the three lines) into the 3.5mm to Lightning adapter, not the TRS (two lines) end.
NOTE:
- External microphones should be connected after launching FiLMiC Pro.
- If a microphone is disconnected during recording it will result in audio sync issues.
- If editing in Adobe Premiere Pro we recommend using AAC as your audio format, as Premiere has bugs associated with AIFF and PCM audio.
