[Guide] ALEXA Mini and iMovie/FCPX/Avid workflow – How to rewrap ALEXA Mini footage to MOV for editing via AIC/ProRes/DNxHD codec?
Follow these steps:
Step 1: Open up HD Video Converter as a ALEXA Mini Video Converter. When its main interface comes up, click ‘Add File’ to load your source media.
Step 2: Select output format for your editing program
To convert ALEXA Mini video for iMovie, from ‘Profile’ list, choose ‘Apple InterMediate Codec (AIC) (*.mov)’ as output format under ‘iMovie and Final Cut Express’ column. This profile is also suitable for use in the discontinued Final Cut Express.
To transcode ALEXA Mini files for FCP X, select ‘Apple ProRes 422 (*.mov)’ as output format under ‘Final Cut Pro’ column. The ProRes codec is also workable in its former version FCP 6 and FCP 7.
To encode ALEXA Mini footage for use in Avid, from ‘Profile’ list, select ‘Avid DNxHD (*.mov)’ as output format under ‘Avid Media Composer’ column.
Important: If you’ve loaded a number of video clips to do batch conversion, please do remember ticking off ‘Apply to All’ option before you start.
Step 3: Custom video and audio settings (optional)
If necessary, you can click ‘Settings’ button and go to ‘Profiles Settings’ panel to modify video and audio settings like video encoder, resolution, video bit rate, frame rate, aspect ratio, audio encoder, sample rate, audio bit rate, and audio channels. 3D settings are also available.
Step 4: Begin ALEXA Mini Video Conversion
When ready, click ‘Convert’ to start format conversion. Once the conversion process is complete, you can click ‘Open Folder’ button to get the generated AIC MOV files, ProRes MOV files or DNxHD MOV files for editing in iMovie, FCP X or Avid with optimum performance.
If you don’t want to wait for the entire conversion process, you can tick off ‘Showdown computer when conversion completed’ and go away to do other things.
