The problem

DaVinci Resolve (free version) can’t load 4:2:2 10-bit files. You’ll need the Studio version if you want to skip this hassle.

The search begins

After searching both Google and YouTube, I came across this video from GuyWithCamera that converted the files into ProRes. He later modified the script to also creates proxies. For the full video, see below:

I was able to modify the script slightly and added my Windows instructions in writing (for Mac, see GWC’s video description).

1. Download ffmpeg.
2. Open notepad in Windows and save the file as “convert.bat” (w/o the quotes) into your folder containing MP4s and MOVs.
3. Use Windows command-prompt to run convert.bat to convert all MP4s and MOVs

The script

ren *.mp4 *.mov

if not exist ".\converted\" mkdir ".\CONVERTED"
if not exist ".\converted-proxies\" mkdir ".\CONVERTED-PROXIES"

for %%A IN (<em>.mov) DO ffmpeg -i "%%A" -c:v dnxhd -vf "scale=854:480,format=yuv422p" -profile:v dnxhr_lb -c:a aac  ".\converted-proxies\%%A" for %%A IN (</em>.mov) DO ffmpeg -i "%%A" -c:v prores_ks -profile:v 3 -c:a aac  ".\converted\%%A"

Summary

If you have trouble loading your GH5 4:2:2 MOVs/MP4s, try the script above. Otherwise, you can always shell out the money to get DaVinci Resolve Studio.

Good luck!
