David Kong here, with my fourth post in this video/article series that is all about working with less gear, for less money, and making it look good.
This article/video is all about Postproduction. I’ll be talking about editing and color correction workflow, Premiere and After Effects, touching up shots with “Visual FX,” and my techniques for handling files. I’ll also be taking a look at a bunch of shots from my Portrait of Macerata video and explaining what finishing work I did on them.
You’ll find the video below, along with a summary of the topics covered.
Part One: The Gear
The first video/article was all about the gear (lenses, filters, tripods, etc). If you haven’t seen it yet, check it out here:
Part Two: All about the Camera
The second video goes very in-depth with the DSLR – I cover everything you need to know about formats, codecs, and dynamic range in order to get the most cinematic images.
Part Three: Magic Lantern
The third video was an in-depth explanation of how to use Magic Lantern and why I love it.
Part Four: Postproduction
The Proof of Concept:
I’m using one of my films as an illustration for all of these concepts, so if you haven’t seen the Portrait of Macerata, check it out here. I’ll be talking about that film all through this series.
The first thing I want to say is that, just like everything else in this series, postproduction works best when you’re flexible. Every project is different, and while there definitely are advantages to having a set process, you’ll work better and faster if you understand all of the details and can tweak the process when necessary. I’m going to present the process that I usually use, and the one which I used on the Portrait of Macerata video, but this is not set in stone. I change it up all the time depending on the camera I’m using, the computer I’m editing on, the turnaround time, the complexity of work required, and the final delivery format.
The video starts with some responses to viewer questions about how I approach shutter speed and white balance.
The very first thing to do with new files when you get them into your computer (assuming you’ve already backed them up) is to rename them. Most of these cameras will give you a generic “MVI_1228″ or similar for the filename, and eventually you’ll end up with duplicate filenames. NOT GOOD. That can really mess up your system and give you lots of problems.
I always add a prefix to all files that I shoot with a short tag to represent the project, or if there’s no project (stock footage, or something) I’ll prefix the date it was shot.
I use Renamer from Den4b.com but there are plenty of other options, just do a Google search.
Adobe Bridge is a good option.
Generally speaking, I’ll transcode into an intermediate codec like ProRes or DNxHD before working with my files, because that speeds things up the computing and allows me to render previews more quickly. The downsides are that it takes some time to create those intermediate files in the first place, and that they also take up a bit more space. On this particular project, I decided not to transcode because I was in a big hurry and didn’t want to wait for the transcode. (I also have a computer that can handle editing the native h.264 files pretty smoothly unless I’ve got a lot of FX)
A more complex cleaning-up process
If you’re going to be doing severe color correction, if you’re brightening the image up significantly or changing the color significantly, there is another process that can help you lessen the nasty artifacts you’ll get. I personally very rarely use it, because it takes a lot of extra time and space, and it doesn’t make a perceivable different on most shots. It can be very useful sometimes, though, if you’ve made a serious mistake on set and need to recover from a severe color or exposure problem. Here’s one workflow: http://vimeo.com/19908622
Premiere and After Effects
I actually prefer Avid’s Media Composer over Premiere Pro as a video editor, but my workflow is centered around Premiere Pro these days because it works so smoothly with After Effects and Audition. I generally will do all of my editing in Premiere, and then open that timeline up in After Effects to carry on with the color correction and VFX process (what we used to call the “online”).
Working with Cinestyle
With a free piece of software from Red Giant called LUT Buddy, you can load in a preset color-correction that will take your Cinestyle-shot footage and make it look more like the standard preset would have looked like with increased contrast and saturation.
UPDATE: It looks like you can’t get LUT Buddy for free anymore Oh well. There are other tools for loading LUTs into Premiere and After Effects, but they all cost money. If you’re using Premiere CC, you can load in the LUT with the Lumetri effect.
But I actually rarely use the Technicolor LUT. I prefer to set my own contrast and saturation manually, on a per-project basis. I will generally make a custom contrast curve using the curves tool instead (or you can use the simpler levels tool if you prefer) and then add a simple saturation increase separately.
For this film, I ended up deciding to go with a contrast curve that was much less contrasty than the Technicolor LUT would have made it. The blacks very rarely hit full black in this film and the highlights very rarely hit full white. I wanted to go with a look that felt more like film than like video. I also added less contrast than the Technicolor LUT would have added, for the same reason.
I ended up not recording on-location sound for this film, so, with one or two exceptions, everything you hear in the film came from pre-recorded sound libraries. Some are available online for free or for license, and if you own a copy of Audition, you get free access to a lot of prerecorded sounds through that. Even though most of the sounds in this film are pretty subtle, they add a subconscious feeling of realism that’s quite powerful. One of my old film professors used to say that the foley and cloth track were the “glue” between the picture and the music.
Premiere and After Effects have some good color correction tools built in for free, but my weapon of choice is Colorista II. It has just about all I ever need to do as far as color correction in one simple place, and it’s very quick and intuitive to use. Red Giant has a simplified trial version for free available here.
A good understanding of After Effects can come in really handy for a filmmaker or video producer. I spent several years teaching myself advanced visual effects techniques, and they come in very handy doing little touch-ups in normal film and video work. I go over several shots in this film that required a little touching-up.
Can you spot the difference? ^
Blow-ups and Stabilization
I know that a lot of you reading this will probably disagree with me, but I actually don’t think that resolution is all THAT important.
Mind you, I will take all the resolution I can get, if I don’t have to sacrifice the artistic quality of my work. I definitely would rather have higher resolution, all other things being equal. But for instance, I would rather have a great composition at 720p resolution than an average composition at 1080p. So, there are times when I’ll blow up a shot if I think that it enhances the image from an artistic point of view. I also ran a little bit of stabilization on some of these shots when I made little mistakes on location, and that involves blowing the image up slightly.
I shot the film in 1080p on my T2i, but even at the original size, the T2i doesn’t resolve nearly 1080p of actual resolution. And on top of that, I blew up a bunch of my shots fairly significantly in post, so I’m rarely resolving more than 720p of actual resolution on this film. But that doesn’t bother me very much. I can still watch Road to Perdition (one of the most beautifully-shot films I’ve ever seen) at 720 by 480 resolution and think it’s spectacular. Is it better in HD? Sure. But Road to Perdition at 310 by 240 is still better than anything I’ve shot at 1920 by 1080.
High resolution and detail is important to me. It’s just comparatively much less important than artistic quality.
Generally speaking, I shoot all my footage at 0 sharpening in camera, and then I add a bit back in post-production before I export.
In this case, I accidentally (no idea how it happened) shot the entire film with sharpness at 2, so I decided not to add any more sharpening in post.
Moving Star Trails
I didn’t cover this in the video because it was already getting pretty long, but if you guys are interested, I might make a tutorial on how to make the moving star trails that you see at the very end of the film. Let me know if you’d be interested in that.
Lastly, I know that a ton of you guys have been anxious to see a tutorial on how I made the motorized slider that I showed in my first video. I’ve already finished shooting it, and I’ll have it out in a week or so!
As always, feel free to ask questions below!
