Importing Dual-System Footage into FCPX

This tutorial tells you about how our equipment stores the recordings that you make and how you transfer those files to your portable hard drive for use in this class. It also shows you how to import these files into Final Cut Pro X (FCPX).

The Basics of SD Cards

Whether you are using the Blackmagic Pocket Cinema Camera, the Panasonic GH3, or the Zoom H6/H5 audio recorder, you will be recording your interviews and footage to “SD” (stands for “Secure Digital”) format memory cards.

SD cards have been around since 1999 and have gotten much larger and more powerful over the years. Initially, a 512mb card was considered large but would be considered ludicrously small today. In September of 2014, Sandisk introduced an extremely fast 512GB card for just a little under $750! SD cards vary in storage capacity (measured in GB) and in read/write speed (measured in Megabytes per second or MB/s) The other less precise measure is “Class – Class 6, 10, etc.” I have found measuring SD cards by their advertised class to be less useful. Pay attention to the write speed in particular when selecting an SD card – that is what matters the most.

Many DSLR cameras and camcorders will record video to slower cards, but only at their lower quality/lower frame rate settings – the higher quality options will not be available on the camera’s menu. I had a student wonder why the video from his Canon 70D looked all muddy. It was because he had a cheap, small, and especially, SLOW SD card in it that did not allow him to access the Canon’s higher bitrate recording settings. Remember, size is not everything! A large capacity card that is slow will be just as useless as a small card. Go big (and fast) or go home.

We use the fastest cards the Studio owns in the Blackmagic Pocket Cinema Camera. This is because the data record rate at the BMPCC’s highest quality setting is very high. Thus, we use the Sandisk Extreme Pro cards that record at 90 MB/s. The BMPCC kit is supplied with two of these cards. When recording in ProRes422HQ, they will hold 41 minutes of footage. They hold closer to an hour in regular ProRes422. In Compressed RAW, they hold only about 13 minutes. (We’re not going to be using RAW workflows in this class.) These cards are fairly expensive, though get less expensive every day. Still, be careful with them. These were the fastest SD cards you could buy two years ago. Not so anymore.

I have supplied the GH3 with the Sandisk Pro (not “extreme”) cards at 45 MB/s. One 64GB card is capable of recording at the camera’s highest quality for almost exactly two hours, which is very impressive and practical.

The Zoom audio recorders can get by with much slower cards and a comparatively small and slow card will record hours upon hours of multi-track audio. (Look for an update to this post with details on the Tascam DR-70 audio recorders recently acquired by the Studio.)

Copying Your Data to the Hard Drive

The first thing you should do after filming an interview is copy the contents of  your SD cards to your portable hard drive:

Since Final Cut Pro X (FCPX) is designed around using a fast external hard drive, I will issue each of you a 1TB (one TerraByte, or 1000GB) Thunderbolt based hard drive, the Buffalo MiniStation. The point of this is that it will allow you to carry your drive to any of the labs on campus that use FCPX to work on your project. The Studio has only ONE editing workstation of its own.

If you do not own a newer Mac that has the Thunderbolt port, the Buffalo drives are capable of also running off of a special USB cable. While USB is not a viable option when running FCPX – it is much too slow – you may need to use it to save the data from your SD card to the drive if you cannot immediately get to a computer with FCPX on it and need to return the equipment. The Buffalo drive can also be read by a PC, but not practically for our use: It requires that the drive be reformatted entirely to NTFS or FAT32 format. NTFS is fast and modern but is read-only on OSX. FAT32 is read/write on OSX but has a file size limit of 4GB so it is basically unusable for filmmaking work.

While you can import your footage to the computer by plugging the camera into the computer’s USB port with the appropriate cable, this is not the most efficient way of doing it. Most computers now (including all recent Macbooks and iMacs) have SD card readers built in. Thus, the first step to importing your footage is to pop out your SD card and put it into your computer’s reader slot and plug in your Buffalo MiniStation Drive.

NOTE: I tend not to copy my cards to the drive outside of FCPX using the Finder. The reason has to do with the way that FCPX identifies footage as it imports it from the card which can lead to synchronizing and multi-cam problems. It shouldn’t, but in my experience, it does. 

How the files appear when stored on your cards:
Blackmagic Pocket Cinema Camera:
The files on the BMPCC are located in the root directory of the SD card… and they are GIGANTIC!

When you copy these files, be prepared to wait. The BMPCC files are very large. Yet the simplicity of this file structure is one of the beauties of the BMPCC.

Panasonic GH3

The GH3 does things a bit differently than the BMPCC. The system it uses is better than most DSLR cameras that shoot HD video, but it isn’t as seamless as the one large file generated by the Blackmagic. This has to do, it seems, with some sort of camcorder tax in Europe. In other words, there is no technological reason for it. What am I talking about? Most DSLR cameras will only record about 30 minutes of video before you have to start and stop – meeting the maximum allowable file size before the Euro camcorder tax applies. This is not acceptable for a long form interview, and the Panasonic line of GH2/3/4 are the only DSLR-style cameras that I know of to date that have implemented the idea of the automatic chaining of files together in sequence. In other words, when the file gets too big, it automatically starts recording another file. Thus, in an interview like the one shown below, which ran a couple of hours, we see 14 files instead of 2, reflecting the number of times the camera was actually started and stopped. You will notice that all of the files are about the same size.

The Panasonic GH3’s file structure.

You will find these files located in the DCIM folder in a “_PANA” subfolder. If you go to import these directly into Final Cut X, FCPX will automatically know where to find the files on the SD card.

Zoom H5/H6:

It is important to understand how the Zoom stores the audiorecordings you make. It is actually very simple but will drive you crazy if you aren’t aware of how it all works. The Zoom H6 is capable of recording six independent tracks (Left, Right, 1, 2, 3, and 4). The Zoom H5 is capable of recording four independent tracks (Left, Right, 1, and 2.) Left and Right are recorded as a stereo pair in the same track as are tracks 3 and 4 on the Zoom H6. Since you aren’t generally recording L and R (these tracks come off the Zoom’s built-in microphone) you won’t probably encounter these files. But if you do, they will be called ZOOM000x-St.WAV where “x” is the number of your recording. Each of the other tracks will be named ZOOM000x-TrY.WAV where “x” is the recording number and “Y” is the track number. See the image of the Zoom’s folders below:

The file structure from the Zoom H6

You see that the Zoom H6 card is formatted with 9 folders. You probably won’t be using more than one folder unless you decide to go hunt through the menus on the Zoom and change the one that you are recording to. Chances are, everything you record will be found in “FOLDER01.” For each time you press “record” and “stop,” the Zoom will create a subfolder in the active folder (FOLDER01) called ZOOM001, ZOOM002, etc. Each of these subfolders contain the tracks that you recorded. In the image above, you can see that the “Start” and “Stop” button was pressed three different times, creating three different subfolders, each containing the Track 1 and Track 2 WAV files plus an “.hrpj” instruction file.

Importing your files into Final Cut Pro X

NOTE: If you are importing files from the BMPCC, you are probably going to want to color correct them first with FilmConvert. See this post on how to do that.

FCPX can be an intimidating program if you have never used any video editing or graphics oriented software before, but it is actually pretty easy to use. It is, however, important to follow directions to make sure your project turns out. There are a gazillion files that go into making an edited sequence – ones you see and a whole bunch more that you do not see – files that are used by the computer to manage its functions. It is important to not lose track of any of these files. Fortunately, FCPX does pretty much all of the file tracking for us. In fact, file management is one of the big advantages that Apple put into FCP in the “X” version over the previous version, “7.” (Don’t ask me where versions 8 and 9 went!) The summer 2014 update made some more important changes by making LIBRARIES the building block of all of your FCPX footage. After a bit of anxiety on my part, I now see that this system is even better for students new to the software and will probably help both of us manage your files more effectively in the long run.

The first thing you will probably ever do with FCPX is import your footage, and that’s all we are going to concentrate on right now. We will deal with only the upper left hand corner of the screen right now. Don’t be overwhelmed by all of the other windows. Forget about all that!!

There are a BUNCH of windows in the FCPX screen. Don’t worry about that now. All we are going to concern ourselves with at this point is the upper left hand corner, the “Libraries” window.

All the gazillion files you will need to make your movie are stored in units called “Libraries.” Libraries are actually a rather complex file structure called a “package,” but like a lot of Apple software, you would never know it. If you want to learn a little more about Libraries, a fellow by the name of Larry Jordan has written a bunch of great tutorials. But you might not want to look just yet if this is all new to you. A Library is essentially a database that you use to organize all of your footage and edits. This is smart, and addresses one of the fundamental problems with old FCP7 in the university setting – to wit, students losing all sorts of files across multiple computers. May we never return to those bad old days!

If you are importing files for the first time, or are starting a completely new project, go ahead and create a new library on your Buffalo Drive to contain everything that you are going to import by going to FILE -> NEW LIBRARY.

When you hit FILE->NEW LIBRARY it will bring up this dialogue. BE SURE that your Buffalo Drive is the selected volume for your new library (here it is DOHS-Buffalo 4). You can name it whatever you want, but please be descriptive of the Library’s content.

My advice to you is to not name your library something like “HISTORY A404.” I will be collecting your drives at the end of the semester, and would like some sort of unique name on your files. Perhaps your own name would be a good thing. Or perhaps the name of the person you are interviewing for this class. Right about now is a good time to think about professionalism and how people perceive your grasp of the concept. I thank you in advance. For the sake of this class, you are probably only ever going to need to create one library. In fact, I discourage you strongly from creating more than one library this semester.

Once you have created your library, you are ready to start importing footage into it from either your SD Card or from the folder on your Buffalo Drive where you saved the files from your SD cards. There are a number of ways to tell FCPX to import media, but the one that I like the best is to right-click on your library in the “Libraries” window in the upper left hand corner and it will pop up a menu that offers you a number of options including “Import Media… ” or [-I].

When you import media, you are either creating an “EVENT” or adding to an existing event. “Events” are where you store the files that you record as well as manipulated versions of those recordings. Libraries may contain many events. If you have used iMovie, events work very similarly. For instance, say you interview two different people, you could put them into two different events in the same library. Or perhaps you want to put all of your B-roll material in one event and your interviews in another. Think about ways that this can help you organize your material. “Projects” are edited sequences that reference the files in your events – something you will learn about later.

Importing Media:

Right-clicking to “Import Media…” or clicking on your library and hitting [COMMAND-I] will bring up the Media Import window

The Media Import window is extremely straightforward. You will notice that all of your devices, or media sources are listed to the left. Since you are importing directly from your SD Card, select it and use the file pane to select the media you want to import. Clicking on a file will show a preview of it above.

When you have selected your media, you can hit “Import Selected.” This will bring up a dialogue box:

The dialogue box for importing media into an event.

You will see that this dialogue box gives you a lot of options, and you shouldn’t just discount them without reading what they say. First, it asks if you want to add to an existing event (if there is one.) In the case above, I am going to add it to an event I already created called “practice interviews” instead of the event “class introductions” by using the drop down selector. (You could import your media to a different library entirely with the next option below by clicking it, or simply create a new event in the library listed by typing a name in to the box.)

Make sure the “Copy to library” button is selected! It should be by default, however. 

After you have imported the files, they usually need to be TRANSCODED. This means that the format in which your camera recorded your movies needs to be converted into the video file format (or “codec“) used by FCPX, a variety of Quicktime called “ProRes.” There are a bunch of different flavors of ProRes, including “lite,” standard 422, HQ, 444, etc. These all have to do with the amount of image data stored in them. The files I imported here came from the BMPCC, which records natively in ProRes so they do not require any transcoding. Final Cut knows this automatically so the button is not checked. This is one of the nice things about the BMPCC camera. While it takes more time to import the BMPCC’s big fat files, I don’t waste any time transcoding them. When you import from the GH3, however, the files need to be transcoded from the GH3’s native format to the ProRes that FCPX needs. Note: ProRes is a type of Quicktime file. Quicktime is a container that uses the .MOV and .M4V extensions. Don’t worry if you don’t understand all of this right now. YOU SHOULDN’T QUIT FCPX or UNPLUG YOUR BUFFALO DRIVE UNTIL YOUR FOOTAGE IS DONE TRANSCODING. I mean, you can, but you will then have to transcode it the next time you hook up. (Note: Because FCPX can work with the GH3’s AVCHD format natively, some people do this. I personally think it is stupid and wastes time in the long run by requiring your computer to work harder all the time. Transcoding is a worthwhile investment.)

Generally do not allow FCPX to fix any audio or video problems when it imports your files. If there are problems, we’ll take care of that when we edit.

Something to think about with the Zoom: If your event already has ZOOM track files in it, and you are importing new ones recorded at another session, there is a good chance that you will create duplicate file names in your event. FCPX will not overwrite the existing files in your event, but you will have two different tracks with the same name in your event (FCPX will put a marker on the new files). You can rename any of the files in the event to help keep them straight, but you might just consider creating a new event entirely when you import from a different recording session.

NOTE ALSO, if you select the folder on the Zoom instead of just the .WAV files, FCPX will tell you that the instruction files are not supported. That’s okay, you don’t need them in FCPX. By just checking FOLDER01 in the import dialogue, it will import all of the tracks stored in all of the subfolders.


It will appear that your files have imported into their event immediately after clicking on “Import.” In fact, when you click on your event in the Libraries window,  you will see your recordings displayed and can even play them. But this does not mean that FCPX is done copying the media to the proper location or transcoding it to ProRes. In the very center of the FCPX window you will see a little circle with a “%” in the bottom of it and a number in the center. This is your processing status indicator, and you will come to hate this little number and window with a passion. Click on it and it will bring up the following status window:

Where your computer’s processing power comes to bear.

The “Background Tasks” window is a status indicator of all of the time consuming things that FCPX does. “Transcoding and Analysis” is the aforementioned transcoding process of converting a video file from one format into ProRes. “Importing Media” is… you guessed it. Until it is 100%, you haven’t fully imported your footage. “Media Management” is when FCPX needs to shuffle files around. “Rendering.” Ah, rendering. We’ll talk about this more later, but this is where the computing power of your system comes into play. “Sharing” is generally the status of exporting files. Lastly, “Backup” is the backup of your libraries. I’m still learning about that one myself.

One frustrating thing that you will notice is that any time you use your computer in FCPX, most of these processes pause. If you are in a hurry, don’t touch the computer, and don’t let it fall asleep. I tend to turn my FCPX workstation so it never sleeps, even if the screen blanks out. Yes, this uses more electricity. If you are concerned, you can set it back to sleep when you are done. Never use your laptop unplugged to import footage into FCPX. All that number crunching its doing takes up power at a higher than normal rate!
