How To Add and Edit an MP4 File in Final Cut Pro?

After importing an MP4 file into Final Cut Pro, it is sometimes still not possible to add it to the timelines and continue the work. It happens so that an average Mac user may notice an error notification that tells: “Error: Out of memory.” Some users believe conversion is the only way out, but it does not always work. Try to convert the target item in MPEG Streamclip to make it lighter. If the attempt fails, you will see a message saying “Error: Can’t prepare the movie.” Even though MP4 may run without any problems, it might be impossible to convert files to that format or edit them.
Before moving on to the existing solutions, let us first discuss what Final Cut Pro is all about and why a person may want to add video or music there. Final Cut Pro is a special Apple’s software, which allows creating your own video. It is based on a 64-bit architecture, which makes it possible to work with complicated, large-scale projects. It offers many effects to design an inspiring video. Once a user adds any music file to the app’s timeline, he/she can make the chosen music run in the background during the video presentation. The software allows cutting the track or performing any other sorts of editing.

Solution: Use a Compressor App

Perhaps, the best solution is a Compressor. It is a stand-alone app for solving similar problems with video and music editors. First of all, it is critical to decide on the format to convert an MP4 file. Do you know the end user? What about the original pixel dimensions and frame rate? Just sit down and mention it on a separate page not to decide on such important factors during the work. An MP4 file will not be enough to use it on, for example, television, so keep it in mind.

You will need to get it and do the following:

  1. Launch Compressor tool.
  2. Find a Drop Zone feature in the upper left corner.
  3. Place the target video files in that zone.
  4. Search in the presets for ProRes 422.

In other words, you should maintain the pixel dimensions and convert to ProRes 422. Try editing in that format too. Before doing so, activate audio in the Eboder panel in Compressor: set it to 48k 16 bit.

Except for this top effective solution, there are several other things you should try. Just involve these search terms: H.264, MPEG, mp4, Long GOP format and the legendary. However, other possible solutions are not as effective as the one discussed above. If nothing works, try a file of another format or clean up the hard disk. Sometimes, the main cause of any failures on Mac is the lack of space.
