Tapeless Workflow in Final Cut Pro 6

December 21st, 2010

Time again for a technical topic. Shane Ross has released two excellent video tutorials for tapeless workflow in Final Cut Pro 7 on Creative Cow (Link 1, Link 2), and since I had to work on a all-digital-file-only project lately, I wanted to share some of the issues I ran into when using Final Cut Pro 6.0.6 and how I adressed them.

On the HD I got from the 3D studio there were all different types of files. Uncompressed .mov, H.264 Quicktime and several .tga, .png, .jpg sequences, most of them 1920×1080, some 1280×720. The final master was to be delivered in 1280×720, which meant converting would be inevitable at some point during the process.

Create reference movies

I decided to convert at the very beginning because editing full-res HD image sequences is a real hassle. To have the computer do the conversion over night I used Quick Time Player 7 to create a reference file for each image sequence. To do this, choose “File → Open Image Sequence…” or press Cmd-Shift-O. Then select the first file of the image sequence and hit OK. A dialogue box pops up where you have to select the proper frame rate. It may take a while till all frames are loaded. Then click “File → Save as…” or press Cmd-Shift-S to save out a reference movie. Select the radio button “make reference movie” at the bottom of the dialogue and save your file with a proper name. Repeat this for all of your image sequences.

Convert with Compressor

When this was done, I launched Compressor and created a preset for my target media, for which I chose the ProRes 422 HQ codec with a frame size of 1280×720, no fields, no audio. Then I imported all of the QT reference movies I created before as well as the H.264 and uncompressed QT files, applied the preset to all of them, set the destination they were to render to (external HD), launched the queue and went to sleep.

Converting using Final Cut

Should you—for some inexplicable reason—not have Quicktime 7 on your computer, you’re having a little more work. Launch FCP, go to “Final Cut Pro → User Preferences” (or press Option-Q… Option is the key that says “alt”), select the “Editing” tab, and set the “Still/Freeze Duration” to 1 frame. But before you import the files, read the IMPORTANT! note below, because you also have to adjust the “Imported Still/RGB Video Gamma” to 2.20. Then drag your image sequence folders to Final Cut’s Browser window, go through them one by one, selecting all of the files of each image sequence and drag them into a new sequence. It makes sense to set up ypur default sequence to the specs you want your output files to be, so in my case this would have been 1280×720 pixels, square PAR, 25 fps, ProRes 422 (HQ) codec, no audio. Otherwise you have to adjust your settings each time when exporting. Then export each sequencs by going to “File → Export → Using Compressor…” and from here it’s the same route as above. Or you can export them manually by choosing “File → Export → QuickTime Movie…” if you don’t need any sleep.

IMPORTANT: GAMMA SETTINGS IN FINAL CUT PRO 6

I don’t want to go too much into detail here, but it is vital to pay attention to FCP’s Gamma settings. I ran into this problem when taking the locked edit to Color, adjusting the image there, rendering the files and taking them back into Final Cut — the colors looked all different. So I exported a SMPTE bar image from Final Cut to Color and realized there is a color shift, but it did not happen when I opened the Color renders in QuickTime Player. Then I figured it had to be Final Cut’s Gamma Settings and when switching to 2.20, everything was okay. So make sure your Gamma Settings are correct, go to “Final Cut Pro → User Preferences” (or press Option-Q), select the “Editing” tab and set the “Imported Still/RGB Video Gamma” to 2.20 (see image). You’re running into all sorts of trouble when you’re on “source”.

Next step: Offline Edit.

With ProRes it’s not really necessary to edit offline, especially because the ProRes Proxy codec is only available from FCP 7 on, but you may want to go for smaller files nevertheless to edit when you’re on the road or whatever. So import your video files to Final Cut, select them all and either right-click or Ctrl-click in the Browser window and choose “Media Manager…” or go to “File → Media Manager…” to launch…the Media Manager! To create proxies (smaller files with reduced quality), choose the “Recompress” option and select the codec of your choice. Adjust all other settings as displayed in the second image. Select a folder where the proxies will be stored (“Media Destination”) and hit OK. In the popup dialogue name the offline project and confirm once more, and then Final Cut will generate the proxies.

Now here’s a caveat: In his tutorial, Shane Ross is using Final Cut 7 which does everything properly. In Final Cut 6 however, I realized that some files are being renamed and Final Cut appends a “-v” to the file names. I don’t know how this is happening or why (nor seems anyone else), but here’s the thing you need to do to work on without relinking issues. In your offline project, select all of your video files and right-click or Ctrl-click in the Browser window to select “Rename → File to match Clip” (see third image). This will rename all the files according to the clip names in one fell swoop. Otherwise the easy workflow that Shane is using in his Offline/Online Tutorial won’t work because the file names don’t match.

Going Online again

So what Shane does is to use two external hard disk drives, one has the Online Media and the other holds the Offline Media. When your edit is locked, you selct your sequence in the Final Cut Browser window, open the Media Manager and select the “Create offline” option from the drop down list, then you set the codec you want to ouptut. Ideally, this is the very same codec you encoded your files with before. Once again, select the folder the Online version of the project will be stored in and give the project a proper name. Close the Offline project to avoid confusion. Next, mount your hard drive with the Online Media. In the Online Project, select all your video files and either right-click or Ctrl-click in the Browser window and choose “Reconnect Media…” or go to “File → Reconnect Media…”, choose “Search…”, navigate to the appropriate folder and hit OK. If everything works out, Final Cut should relink to all Online files now. If not, well, you’ll have to relink the files manually. But you shouldn’t when you followed the steps above.

Finishing

When your sequence matches your Offline edit (hopefully), you can now take the Online version to Color or Motion or whatever you need to do. A few more pieces of advice here:

  • When working with both Motion and Color, bear in mind that you need to render clips from motion back into Final Cut as physical files because Color won’t recognize the “soft link” between the Final Cut edit and the Motion effects that are only rendered in the Final Cut Timeline.
  • Don’t use speed ramps when working with Color, it can’t handle them and will screw everything up. Color can handle clips with a constant speed change, no matter if positive or negative, but when you use speed ramps, you need to render your clip to a file and bring it back into your Final Cut Timeline.
  • Don’t forget about the Gamma issue, especially when you’re grading on a different system than you’ve been editing on.

Now and Then

September 29th, 2010

Currently learning a lot of stuff about digital 3D modeling and compositing, I found it very inspiring to discover this video in which Visual Effects master Douglas Trumbull explains how they did the Hades landscape for Blade Runner, 30 years ago. Awesome.

The Hardest Part still remains

July 8th, 2010

A few days ago a somewhat heated debate went on at Motionworks. Well, it wasn’t as much of a discussion because in general the participants agreed on the topic. One thing that was still surprising was the lack of culture and, say, humilty and appreciation in the discussion itself. How hard can it be to write “Thank you”? But that’s not my point today.

What’s worth a closer look is the topic of the aforementioned issue, namely: “Does the increasing amount of online tutorials devalue the (established) artists?”

No. Thank you for reading.

Okay, let’s roll this out a bit. Yes, there are hundreds of tutorials online, even for free, only the number and variety of which could easily let one assume that you can learn how to be a Motion Graphics Designer in 2 months. And this assumption is of course ridiculous, because teaching some a technique doesn’t make them an artist. No one’s becoming the next van Gogh, Picasso or Warhol because you show them how to hold a brush.

One field where teaching people how to do stuff has actually boosted the business is cooking. Thanks to all the Nigellas and Jamies there are more people going more often to restaurants spending more money. That’s counterintuitive because we assume that if we tell people how to perform or improve daily actions, they do it all themselves. But what has happened is that people got more educated on the art of cooking and were willing to spend more money on good cuisine.

And there’s another ingredient that’s essential for creating: inspiration. Without the 1% of inspiration the 99% perspiration are not work, they’re labour. People don’t pay a lot for stuff that hasn’t got “it”. So why go there at all?

The hardest part, figuring what to put on the empty canvas, has not been changed. Knowledge of a series of techniques won’t let you do that. That’s just copying. Like assembling LEGOs, it’s fine and good to follow the instructions and build the spaceship, but it’s great when you mix the pieces of several boxes to model a submarine. But the real art is inventing LEGO. Something that enables people to craft with their creativity. Like the Web 2.0, in a certain way.

So the hardest part is still the same, and people who can solve it will still get paid well. It’s only that the perceived entrance barrier to this field has been lowered. But this doesn’t change the game. Not yet.

Bite-sized high impact mentoring

April 30th, 2010

Robin Dickinson, who is the brother of Motionworks artist John Dickinson, runs a business development company called radsmarts. Not only does he this name justice by what he does every day, he also has a valuable series of short mentoring video clips on his page. Terrific. Thanks Rob!

Now that is an amazing short film! Make sure you watch it all the way through.

3D for you and me

March 17th, 2010

FX makers idustrial revolution have posted a tutorial (sorry, they seem to have taken it down in early 2012) on how to create 3D video using Apple’s Motion and Final Cut Pro with a plugin called Stereo 3D Toolbox, made by DP Tim Dashwood. Tim also has a series of tutorials for 3D editing and compositing on his site. Terrific! [Update: Tim’s place has moved to dashwood3d.com.]

Ten years earlier

March 17th, 2010

Everyone (including myself) feels a little stuck now and then, and sometimes, a (despaired) thought springs to mind: “If I were born ten years earlier, I’d have a better standing in my industry today.” The range of years may vary because every industry and organization seems to have their own, say, rhythm or evolution periods.

The point is, ten years earlier, it was much harder to get where you are now. What gets you here today didn’t get you anywhere 10 years ago. Good news: In ten years’ time, the stakes for the ones to follow will be even higher. For example: If you wanted to be a great Compositing Artist to work on Lord of the Rings ten years ago, you would have had to get started doing compositing in the early 90s. Back then, it was close to impossible to find a company that would even do this on a computer workstation, because NLE hadn’t even entered the mass market (and workstations that could do these kinds of effects cost as much as a spaceship. Well, almost.). Or in marketing, ten years ago direct mail, cold calls and door to door sales were king. Anybody want to try them today? Same with music. What used to be extreme and edgy ten years ago won’t impress as much today.

Back then it was the freaks, the people who were really passionate about their ideas, who would lean into it and do whatever it would take to turn vision into reality. This hasn’t changed. The only difference is they were pioneers, today there’s a field you have to surpass. It has become harder (but not impossible) to be pioneer from the very beginning. Most boundaries that used to be on your doorstep ten years ago are now somewhere out there. But they haven’t gone away. Now you have to find them before you can push them. That’s why expertise matters, and the only way to build your own expertise is to do what you’re passionate about.

Skip over DVD tracks

March 10th, 2010

Here’s a short tech hint:
When authoring a compilation DVD with multiple tracks, there’s a little problem when using a “play all” script, because you can only skip from chapter marker to chapter marker within one track, but not from chapter marker 10 in track A to chapter marker 1 in track B, which would be next. What does the trick quite well is to insert some black (or whatever colour you want) frames at the end of the track and put another marker there, so you skip to after the last picture of the current track and the track ending script is executed, loading the next track.
