When you add video files like MP4 to Davinci Resolve, you may come across problems. This could happen because of the different video or audio codecs in a number of MP4 files as Resolve(even the latest Davinci Resolve 12) might not support all of these codecs. First of all, have a look at the related issues:
Q1: Sony A7s audio problem
I have been just importing Sony A7s MP4 files into resolve and it tells me there is 0 audio channels. When I open them in abobe premiere the audio is there. This happens both in Resolve 10 and 11 beta.
Q2: Sony F3 MP4 file is black in DaVinci?
I have a short film, shot by ARRI Alexa and Sony F3. The alexa mov files are ok, but Sony F3 files with mp4 file format are black in DaVinci. I imported XML file from Premiere Pro CC to davinci. I tried to load only one mp4 file into davinci - and again its black... Any suggestions?
As a quite hot file extension, MP4 is widely used for saving media data and can be found in lots of places online or off line, which means, you may download MP4 videos from video sharing sites such as YouTube and Fox, or from Camcorders like Sony A7S(XAVC S encoded MP4), Sony XDCAM PMW-EX3, PMW-F3 PMW-EX1R, PMW-200, PMW-100, and PDW-F800, etc. According to Davinci Resolve's offcial site, Resolve does not support mp4 files, or any compressed audio file formats. To solve the MP4 and Resolve issues, the easy workaround is to transcode MP4 to a more editing-friendly format, such a Resolve's DNxHD.
