Thanks again.
MP4 best converted to what?
D.
It depends very much on your storage capacity and implementation.
Transcode creates data.
Mp4 is a container such as QT that holds the datas, so to say.
If your codec is H.264 it's not that great for editing because it requires a lot of calculations and could slowdown.
(I remember that when I started to use Red, it was playing smoother in the NLE with the decode settings to 1/8 than any of the 4k MP4 highly compressed...and that, without the Red Rocket!! That would happen also into Mistika without the help of any Rocket.
Sometimes even HD avchd from certain devices was not that smooth.
AVCHD is a format that uses the codec.
You may well choose DNx on PC or Prores on Mac.
But the reason why you'd have to transcode is what Paul's pointed: if there are audio data issues in some MP4 containers with Resolve then what's your choice?
As you are on PC, my bet would be DNxH.... Check Avid tutos on the use of the different flavours.
But with DNx you are safe everywhere.
Now...I ignore if the Hdcinematics converter Paul pointed above allows an unofficial convert to Prores on PCs.?? Before it was possible with this, that was called clipztool or something like that.
In this case it would be awesome because to my knowledge, the only software that cuurrently allows to export Prores on Pc is Scratch from Assimilate.
Not cheap, big learning curve.
Edit: BM Fusion allows also to write Prores on PCs!
