I'm trying to take a script that converts 4K MP4 video from my Sony RX10 iii camera to a format editable by Davinci Resolve. For testing, I have the script print the string before it calls it. If i manually copy that string direct to the command line it works perfectly. But when the script calls it, it makes a video from just one frame. How call I correct this? Here's the script:
red []
f: request-file
str: to-string mold f
in-str: trim/with str "%"
out-str: copy in-str
replace out-str "MP4" "mov"
print out-str
ffm-str: rejoin ["ffmpeg -i " in-str " -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a pcm_s16le -f mov " out-str]
print ffm-str
call/wait ffm-str
quit
f: request-file
str: to-string mold f
in-str: trim/with str "%"
out-str: copy in-str
replace out-str "MP4" "mov"
print out-str
ffm-str: rejoin ["ffmpeg -i " in-str " -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a pcm_s16le -f mov " out-str]
print ffm-str
call/wait ffm-str
quit
if it's windows we're talking about
also ensure you're using latest, not stable, build
I'm using archlinux, not windows. The build of red I'm using is about a week old.
Is there any way to make the resulting file overwrite the existing file?
I don't understand how red can call the wrong codecs though.

it's kinda weird that Resolve would only support Quicktime format
it's a very ancient format
I been playing with it. It uses gtk
