I'm a n00bie with video production.
I installed ffmpeg. It's recognized.
So I tried my first conversion.
ffmpeg -i earth.webm earth.DNxHD
and, then, after searching:
ffmpeg -i earth.webm -f DNxHD earth.DNxHD
In both cases I get the following error:
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!
What I gather from that is that the default settings did not work and ffmeg wants me to include those values.
And that's the problem. What values should be selected for these unknown files? (I grabbed them from the web - they're copyright free - and want to use them in Da Vinci Resolve (hence the need for DNxHD)
Included is the error msg
