Screen Capture and Video Editing for Linux

December 31, 2008

I’ve been bemoaning the lack of video-creating support for Linux and apparently, I’m not the only one.  I just caught Steven Vaughan-Nichols’ recent article on the subject and I had wanted to add screen recording to my wish-list of 2009. It sure would be nice if CamStudio were ported to Linux.  But now I think I might not have to.  There are a couple of web apps that might just fit the bill.

ScreenToaster and Screen-O-Matic are two web-based screen recorders that look promising, as long as the microphone functions properly.  And I have yet to test either of these programs nor have I tested my mic in Linux.

As far as I can tell, neither of these have done a lot of testing with Linux.  I saw where Screen-O-Matic claimed minor issues with RedHat Fedore Core 3 with Firefox 2.0, which looks like an old configuration to me.  For Vista, XP and Mac it was all good with Firefox.    So this post serves as a sort of placeholder for me when I want to try this out, as well as an invitation to the rest of you to try it and then let the rest of us know how it works.

And this might be the answer to more and more of the typical Linux woes.  There were several attempts to try online non-linear video editiong in 2007, but most of those are gone as of the end of 2008.  The most promising, so far, looks like it might be JayCut.   Unlike the now defunct YouTube mixer and Jumpcut (which was bought and then abandoned by Yahoo) it does allow downloading of the finished product.  The online video editing is still in its infancy, but perhaps in 2009 there might be something better that comes out for orphaned Linux users who are not using the DOS-like command line.

For screencasting and video editing, the ability to download the finished product is key.  As demonstrated by the Jumpcut fiasco, it is too easy for an outfit to be abandoned and then you can lose all your stuff.  That particular move by Yahoo indicates to me that they might deserve to be bought out by Microsoft.

I’m looking forward to seeing what new discoveries I can make with Linux in 2009.  My 2009 wishlist includes:

1. Simple and stable nonlinear video editor

2. Simple screen recorder with the possibility of adding annotations ala Camstudio

3. A Linux capable of finding my Dell laptop webcam

4. A more complete WINE capable of running at least all of the old Win98 programs instead of trying to keep up with the latest stuff.  I have a ton of old apps and games that could use a new lease on life with my kids.

5. A painless way to export my Thunderbird and Firefox settings to either windows or to another machine or just so I can upgrade to another Linux distro.  Mandriva has worked okay on my Dell Vostro 1500 but I’d like to try the latest Mepis without losing all my stuff.

Video Editing in Linux: Kino v Open Movie v KdenLive

August 10, 2008

I have yet to see a decent article on using video with Linux, so I thought I would write one. I’ve been working with video and posting my clips on YouTube using Windows Movie Maker 2. It is an adequate program, but I’d like to find something that could be as good or better in Linux. Could I pull it off? Follow along and see…

I used a Canon Powershot A630 and captured the video on an SD card. The video was only about a minute long, just to keep it as simple as possible.

Would PCLinuxOS be able to read the output? Would I be able to edit it with a title and maybe add some music? Would I be able to post my video on YouTube? Let’s see.

I was looking for some likely video editors and these were on my list:

Kino

Cinalerra

Open Movie

KDEnlive

I’ve been using Movie Maker for all of my videos thus far, so anything I used in Linux would at least have to measure up to that. I had not used any of these but did some research on each of these and downloaded everything except Cinalerra. I’m not opposed to Cinalerra but didn’t want to spend scads of time learning features I would never use. I wouldn’t mind trying it eventually, but this is a basic project. Capture, edit, render and post. Once a body does that, we can experiment and tweak.

PCLOS was able to read my SD card, no problems. That’s more than I can say for my niece’s laptop which is running Vista. Oh well.

Meanwhile, I’m also playing with Ksnapshot for screen capturing. I’m definitely expanding my skill level with this exercise!

Kino

Kino looked pretty simple until I tried to import my .avi file. Then it acted confused as it wasn’t a DV file. I said import anyway, and away it went. It said it might take awhile. Okay. So I waited for a couple of minutes. And then some more. This movie was about 90 seconds long, so I was not going to wait forever. I purposefully made the clip short in order to limit processing and rendering issues.

Finally, it imported, taking a full 3 minutes. Next, I went to the timeline.

The Kino Timeline

The Kino Timeline

This did not look like a timeline view to me. I had a series of clips, each about 6 seconds long. I clicked the Trim button and saw that I could do a little basic editing, but it was not a timeline format I was familiar with using other editors I had fiddle with. Even the editor that comes with Nero seemed more full featured than this!

I looked at the export feature just to see what it looked like and it appeared to support several formats including some DVD options. But I decided to look else where to do this project. I didn’t see anywhere to put titles especially in light of not having a proper time line. Perhaps I missed something? I may need to do more research in order to warm up to Kino. NEXT!

Open Movie

For some reason, my package manager did not install Open Movie in the menu, so I ended up searching for it. Then I put an icon on the desktop.

Now here was an editor that I could understand a bit better. There was a more “normal” timeline with multiple tracks with the capacity to add even more audio and video tracks. But I ran into trouble when trying to add any effects other than a title. Plus, the program would simply disappear whenever I tried to preview my movie.

More research needed. I did look at the export options, and those options looked a bit complicated for someone used to using Movie Maker. Lots of promise here, but I need to be able to preview without the thing crashing.

NEXT!

KDEnlive

I’m running out of options, here. Kdenlive came on to the scene relatively recently, and I was keen to give it a try. I had seen some YouTube videos made with this program, so I knew some people were using it. Could I use it?

The default video format stymied me for a bit. ATSC is something I hadn’t heard of before. Reading a bit, it sounded like a fancy name for mpeg-2. Okay, moving on…

Next I could decide how many audio and video tracks in my project. Movie Maker only allows one video and 2 audio so the flexibility to add more is nice. I decided to stay with the default of 2 and 2.

Next I was greeted by a screen that looked intuitive as it really seemed to fit with the KDE theme. Perhaps this would be the one.

So I went to Project>add clip and was able to browse for my movie clip. I was able to drag it to the timeline. So far so good! Next, clicked the “play” button in the preview window….

Not good. Not good at all.

So I tried it again, and the second time it worked. I have no idea what I did different if anything. So while I knew I might crash at any time, I also knew this program showed promise. So it was time to save before it crashed again.

Time to add a title, which looked like it needed to be a text clip. So I created and added it…or at least I think so.

It didn’t show up in my preview.

Okay, so far so good. Let’s render this thing out, shall we?

Under file, I tried “export timeline.” Good choice.

I had a lot of choices for high and medium quality. Medium is good enough for the moment so I picked mpeg 640×480 high. So far so good. Lots of audio choices, too. Now I’m starting to feel a bit overwhelmed as there really are a lot of choices here!

I finally clicked the export button and let fly. It said it should be finished in about 5 minutes and had a progress moniter to show me how things were going. This is the furthest I had gone with any of the programs and was looking good.

After rendering, the title still did not make an appearance. I went back and tried to fiddle some more but never was able to make the title appear in the preview window on top of the clip.

There were still choices available in Movie Maker that were lacking here, such as toggling between timeline and storyboard view and number of transiton and effects. But overall, this program is a pretty good fit. Or it would be without the niggling defect of not seeing the Title/text screen I created. I did not play with that many features as I wanted a quick and dirty demonstration just to see if using Linux with TouTube was even possible for a noob like me.

Out of the 3 programs previewed, I liked Kdenlive the best, but not having the Title show up was a real bummer. Kdenlive could eventually become my editor of choice by the time it gets to 1.0 status. The trick is going to be to keep the development moving and thus keep my interest alive. This type of progression is what has helped Linux reach critical mass as desktop choice. It is good enough now to hold the interest of the average user, even if it not totally perfect. Handling video tasks such as screencasting, editing for online viewing and working with webcams are going to be crucial in order to make this OS viable for the future. Video rendering remains one of the most intensive tasks most home computers do and it is becoming more and more necessary for business. The future of computing is in video, and Linux is woefully behind in that area. This is why Macs have seen such a rise in sales is because iLife makes video creation so easy and painless. Most prominent YouTubers are using Macs. It would be nice if Linux could at least make an appearance but right now Linux is in sad, sad shape in the area of allowing average users to generate content.

The finished product isn’t anything too special but here it is:

The good news is that I was able to completely capture and render the video and post to YouTube within Linux without having to go into Windows.  And really, that was the ultimate objective.  I’ll still use Windows for the majority of my video work, just because it is faster at the present time and plays nicely with my webcam on the laptop.

I’m also in search of screencorder software, similar to Camstudio.  Or it would be cool if Camstudio were ported to Linux. I feel this type of software is crucial to further development of Linux.  That is because no one is going to sit down with a book or manual to learn about Linux or software.  But they will watch a series of short, concise video tutorials on the subject.  I can learn more from 4 minutes of video than an hour of reading a technical manual.  I can’t do code, but I could make technical support videos for Linux if there existed the right tools.  The Xvidcapture that I found isn’t quite cutting it, even though it’s a good start.
