TransMXF perfect transfer JVC GY-HM850 AVCHD to ProRes

Shortly before, a friend recommended me Aunsoft iMedia Converter for Mac. It is an intuitive app which can help me transcode JVC EX255 AVCHD to Apple ProRes 422, ProRes 422 HQ, ProRes 422 LT or ProRes 4444 to ensure maximum editing quality and efficiency when working with Final Cut Pro X. Now JVC has announced new HD GY-HM850 which also records AVCHD footage. 

We can directly use MP4 and MOV quality. However, as to AVCHD recordings, I always choose to transfer AVCHD clips to Apple ProRes Codec. The iMedia Converter for Mac is the most fastest conversion tool I've tried. Now I am studing the output profile of this JVC AVCHD to ProRes Converter. More than GY-HM850 AVCHD to Apple ProResconversion, I find I can convert  GY-HM850 AVCHD contents to AVI, WMV, MPEG, FLV, DivX, MP4, MPEG-2, WMV9, etc. 

JVC GY-HM850 best review

The ProHD GY-HM850 has built-in networking protocols so you can attach available USB modems/Wi-Fi adapters and stream live footage while simultaneously recording to readily available SDHC/SDXC media.The GY-HM850 uses three 1/3” CMOS sensors with 12-bit processing to capture Full HD at up to 60p. JVC’s Falconbrid processor provides the power to simultaneously record two different formats. The camera records to standard formats that are native to many NLE systems, recording to your choice of Mov, XDCam EX-compatible MP4, as well as AVCHD Progressive, and H.264 Extreme High Quality at up to 50 Mb/s.

Below are my experiences on converting JVC GY-HM850 AVCHD to ProRes MOV for FCP X.

Step 1. Add MTS footage

Once you run the program, click “Add Video” button or “Add from folder” button to load your source MTS files. 

Step 2. Choose output formats

iMedia Converter for Mac offers optimized format presets for Final Cut Pro, “Final Cut Pro -> Apple ProRes 422 (*.mov)”, “Final Cut Pro -> Apple ProRes 422 HQ (*.mov)”, etc. Choose a one you need.


If the default settings do not fit your needs, you can click “Settings” button to adjust audio and video parameters as you like.

Step 3. Conversion

Click “Convert” button and the selected MTS files will be converted to Apple ProRes encode mov files. You may check the converting progress and set auto shutdown in the conversion window. After conversion, click “Open” folder to find converted footage for importing to Final Cut Pro X.
