PC Video in REAPER 4

Friday, October 28th, 2011

REAPER 4 has brought quite a lot of improvement to REAPER video handling. With a little creativity it’s possible to add titles, cut between multiple clips, and insert stills, all with reasonable stability, excellent performance, and great audio processing. I’ve done a blog post and a video about using REAPER to sync audio and video, but I thought I’d do another one that looks at making a complete simple music video, with titling and overlays.

Keeping Up with REAPER Video

The REAPER forum is a regular stop for me. That’s where I learned about video in REAPER and where I look for the latest info. The video implementation is actually still in Alpha form, so it’s not fully supported and documented. Here’s the thread that announced the use of FFmpeg libraries.

Forum member airon has created a thread where he tracks the current state of video in REAPER, “Video Playback and Exporting” that I check often. He keeps it updated with the current FFmpeg libraries of choice, along with other news and tips.

Here’s the Cockos Wiki page describing video support. It includes details on installing the library files.

With all my enthusiasm, please remember that there are no video effects in REAPER currently. No fades, no transitions, no flipping or stretching. All we can do is move clips (and stills) around, trim them, and sync with separate audio tracks. So our style will be defined by those limitations.

Titles and Tricks

A static title is pretty easy to add to your project in REAPER. Just create a jpeg or png image in your favorite tool, heck, Windows Paint will do the job. Be sure to set the size to match your video, for instance 1280 pixels wide by 720 pixels high is a common HD video size. Start with an image or create a gradient, then add text, maybe in a couple of stages or pages. Then drag these into REAPER, drop them on the project timeline, and stretch them to match the tempo of your clip. You can see this technique in action in the tutorial video below.

You might have stills that contribute to your video, or a second or third camera shooting. Or you can extract stills from your video and use those for effects. REAPER 4 can handle multiple tracks of video along with multiple tracks of audio. The audio from all the video tracks will be part of the mix, but only the lowest (highest track number) video will be displayed. Once again, watch the video below to see these operations.

If you mute a video track it stops displaying the video as well as turning off the audio. To eliminate the audio but keep the video, just turn down the volume slider on the track, or use the Item Properties to turn down the audio.

Syncing and Slicing

The audio waveforms displayed in REAPER make syncing multiple video and audio clips a snap, especially if you create a sharp noise at some point when all the devices can capture it. The is exactly like the old “clapper board” you see in movies about making movies. You can simply clap your hands to get a spike in the audio that makes syncing easy.

Once you have tracks synced, take care to keep them that way. Use Item / Group to join items, or be careful to select all the items that belong together when you move, stretch, or trim items. In the video below observe how easy it is to select multiple items to keep them in sync. Also, I’m using ripple editing most of the time to maintain the correct relationship between items.

Cutting video items is just the same and just as easy as cutting audio. Select the item, position the edit cursor, press the S key, and your item is split at that point. As above, make sure all the items that you’re keeping in sync are selected and get split appropriately. I use ripple editing a lot when I’m trimming out parts of my videos.

Tweak the Audio

Even though there are no video effects available, the full range of audio processing definitely is present when working on video in REAPER. For instance, the clip I’m working on in the tutorial video below was shot with a Zoom Q3HD for the main video and audio. I raised the level, added some compression, applied a touch of reverb, and then put a limiter on the output to make sure I didn’t clip. The Q3HD delivers pretty clean audio but it tends to be a bit low in level and punch, so the ability to tweak the sound really adds to the usefulness of this little camcorder.

Rendering

Currently the h.264 video codec seems to deliver the goods for internet video. With the FFMPEG codec library installed in REAPER this is my preferred output. So I select the following options:

Output format: Video (FFmpeg encoder)
Format: QT/MOV/MP4
Size: 1280 x 720
Framerate: 29.970
Video codec: H.264
Bitrate: 9000
Audio codec: 16 bit PCM

Watch the Action

I used the Q3HD and a Creative Vado 3rd Gen to shoot an old Hawaiian slack key standard, My Yellow Ginger Lei in the style of Uncle Leonard Kwan. I decided to turn the video into a little tribute to my Kathy Wingert Model E guitar, so I used the guitar for the title still and shot a video of the guitar on a stand. Then I used REAPER 4 to combine those elements into a final clip for YouTube.

While I did the editing job, I shot with a couple of Sanyo Xacti HD2000s and recorded audio on a Zoom H2n. I edited those together to create a tutorial video:

and by the way, I put that tutorial together in REAPER 4 as well.

If you’re interested here’s the finished version of My Yellow Ginger Lei on my slack key channel:

I don’t think anyone is going to cut a major motion picture in REAPER, but as a way to tweak YouTube performance clips quickly and easily with an emphasis on audio, it’s a pretty decent tool.

    Great video on video editing. How do you tell Reaper what video you want viewed when there are multiple videos running on different tracks? How did Reaper know to prioritize the stills you placed rather than just staying on the video tracks?

    Thanks for stopping by and commenting.

    There are two ways to select from multiple clips, and stills are treated just like video clips.

    The bottom most clip at any point is visible, and I usually create an empty track below all the others where I paste segments from the available clips. When I want to display the still, I place it in this bottom track and stretch it to the length I need. When I want to select one camera or the other, I copy from the original and paste it into the bottom track.

    The Mute function mutes audio and video. And it can be controlled by an envelope tool. So I start off with all the tracks muted except one. Then I mute that track and unmute another to switch from one track to the other.

    Little details like snapping and markers help with both approaches.

    Hi! Your video has helped me a lot. Specially the clapping and syncing tips. In the Reaper I have installed in my laptop when I go to render video I do not have the option of rendering to mp4. I installed the codecs in the reaper folder but it’s still not working. I wonder If you had this problem too. Thanks in advance!

    When I have the FFmpeg libraries installed and select “Output Format: Video (FFmpeg encoder)” I can then choose “Format: QT/MOV/MP4” – but in fact the output is created in a .MOV file rather than an MP4.

    Thanks for the great tutorial. Do you know if you can time-stretch video in Reaper? Thanks

    I just tried time stretching a clip and it worked on the audio but now the video and audio are out of sync, so at least in one little test it didn’t work.

    Basically, don’t expect to do anything but trim video clips and switch between them.

About the Blog

    Howdy, my name is Fran Guidry and this is my Homebrewed Music blog.

    I play Hawaiian slack key guitar and recorded my solo acoustic CD at home. Most of the recording information I find on the internet seems focused on bands, drums, multitracking, and so on but my main focus is recording solo acoustic guitar. Lately I’ve been enjoying video recording along with audio, so that shows up in the blog as well.

    I’m also a guitar nut. I love big ones and little ones, handmades and factory guitars, cheap ones and expensive ones. So I’ll be sharing the fun of exploring guitars as well, along with the challenges of amplifying acoustic guitars for live performance.

    Welcome!

Philosophy

    My recording philosophy is pragmatic, skeptical, not super critical. After all, the performance is by far the most important component of a track, and every aspect of any recording is a matter of taste.

    But I do like to know “about stuff.” Back in hifi days I learned about double blind testing. I learned that we humans can easily hear differences that don’t really exist. The more I’ve learned about our human auditory system, the more I’m skeptical of what people say they hear, especially if they claim that a particular microphone or preamp or cable has some magical property.

    I’ve only been recording since 2001, and when I started I found the usual places on the internet. I sought advice and accepted it, thought I would improve my recordings by using more expensive equipment. It didn’t work.

    Two things that did seem to lead to better recordings were experience and room treatment. Getting an appealing sound is the combination of many small details, and learning those details only comes from experience. Amd the sound of the recording space is obviously a big factor.

    I’ve only recorded seriously using digital technology, but I remember trying to record rehearsals and gigs back in analog days. I don’t have any nostalgia for analog recording and playback systems at all. I think even low end digital systems can capture marvelous recordings. So when I look at gear, I look for good specs: low noise, broad flat frequency response, wide dynamic range, low distortion. I’m not interested in colorful components, mics and preamps with a sound, I want the sound to be the sound of my guitar.

    But the last word is that I’m just learning and I hope you find something useful in my posts.
