An Intro to Video Editing with Kdenlive Part 4: Using Effects

[MaisieIsAwesome]

UHHH i cant change the speed, its not letting me!!! how do you do it???

[jamho93]

with what and how did you do your intro?

[thisweekinlinux]

@jamho93 The intro to this video was done with Kdenlive, a couple of images, and stock video footage from pond5.com

[XeonTechHD]

I Don't have drop down arrows on my effects. Help please?

[thisweekinlinux]

@XeonTechHD this video is from a very old version of Kdenlive. things have changed quite a bit. I think with the newer version, if you go into the effects list, you have to hit spacebar on the categories to get them to expand. Alternately, you could right click on the clip you're adding an effect to, and select the one you want.

[CrazyMan42DABOMB]

What program do you use to do the screen recordings? I've been trying to get the same results out of XVidCap, but to no avail. Is it because I installed with Wubi, which I have heard slows Ubuntu down?

[thisweekinlinux]

@CrazyMan42DABOMB I used to use gtkrecordmydesktop, but waiting 30-60 minutes after recording a video for it to encode was ridiculous. I now use Kazam screencaster, or just ffmpeg from the command line.

[jasbk]

hey hi, great vid. how would you add a "glimmer" effect to a logo?

[lucskywalker16]

Finally! I've been looking for the time stretch w/o reconstruction/deconstruction and you gave it to me (speed for those of you who didn't know either)

[Skopuningurin]

I started using Ubuntu about 6 months ago. ( A friend of mine showed me his, and then I wanted it too. I downloaded 10.10 and installed it with out any problem, and It works just fine ) Since I got Ubuntu I've been looking for a decent video editor, not too simple, neither too advanced. Kdenlive is the solution! Thank you so much for your tutorials! The part about transition is very useful, as I could not figure it out! Thanks mate!

Your weekly updates are very useful too! :)

[thisweekinlinux]

@Skopuningurin glad Kdenlive is working out for you! I need to take some time and make some newer, more updated tutorials on it. Perhaps after the new version comes out (if it ever does...)

[TheDahlakArchipelago]

Good stuff!

[TechnologyFreakMan]

Hey, i just installed kdenlive, but i have no effects?

[thisweekinlinux]

@TechnologyFreakMan which distro are you on?

[TechnologyFreakMan]

@thisweekinlinux Ubuntu 10.10 64bit

[Cristy2603]

@TechnologyFreakMan Yeah, I think you are using 10.10. Use the enter key from your keyboard to see the effects from each category.

[swantonhhh]

I have a Mediocre laptop and every time I playback a video in Kdenlive (Project,etc.) it comes out choppy. Is there a way to help play smoothly?

[thisweekinlinux]

@swantonhhh video editing is a bit of a resource intensive process. Is it always slow, or is it just when you're using effects/transitions? I've noticed that even my computer can slow down some when using certain effects (because I'm running them on 1080p video). It might be worth trying out a realtime kernel, as that's supposed to improve some performance for studio-type applications.

[mattburnsey]

Awesome videos! I was a little disappointed when I started messing around with KdenLive, I couldn't find the features I was used to in windows. Very clear, very fast (which is great, nothing worse than sitting through a tedious presentation), thanks so much!

[thisweekinlinux]

@mattburnsey Thanks so much!

[jrComputerLabs]

Great series on KDENLIVE! Cheers.

[thisweekinlinux]

@jrComputerLabs Thanks a lot! I'm actually going to be doing a talk on this series at Ohio LinuxFest next month. :)

[GreenMeanieUK]

Hey,

Thanks man for making these videos and keep up the good work.

I was wondering how do you change the layout to look like yours?

[thisweekinlinux]

@GreenMeanieUK :) I was glad to do them. To make the layout look like mine, just click and drag all the items on the upper half over to the left-hand side (except for the monitors), so you have transitions, effects, project tree, history, etc. all in one section of the screen. each piece can be pulled out and moved to a dfferent place by grabbing the top of it and dragging it out.

[zaipai]

I tried to use the Youtube render profile, and it tells me I don't have the audio codec AAC installed. Where can I get that codec. Because of some work I do in Windows I have a valid license for it.. I noticed you did not have that/this problem.. Any advice would be greatly appreciated..

[thisweekinlinux]

@zaipai You might try:

sudo apt-get install libavcodec-unstripped-52 libavdevice-unstripped-52 libavfilter-unstripped-0 libavformat-unstripped-52 libavutil-unstripped-49 libpostproc-unstripped-51 libswscale-unstripped-0

to get it working.

[zaipai]

@thisweekinlinux Thanks, it did not work unfortunately, it still says Unsupported Codec: aac .. I just need to do some googling.. Thanks for the help... I believe you managed to get me one step closer..

[thisweekinlinux]

@zaipai Sorry, I forgot to mention, after you do that you need to run the configuration wizard again by going to Settings -> Run Config Wizard and accepting the settings you want there.

If that doesnt' work you might try removing / renaming your .kde folder in your home directory and letting Kdenlive rebuild it (if you're on Kde, don't do that).

[zaipai]

@thisweekinlinux I did find out I had to enable the KDE repos for media, or at least that was what I was told I needed to do. Some thing about KDE apps not always seeing whats installed for Gnome.. I reran the wizard and the Youtube option was not there. I selected the 720p/25fps and that matches my camera, so I am hoping it will work. I will keep you posted... Thanks for the advice..

[enduser64]

I have a problem with ogv files (from recordmydesktop). it appears white in kdenlive.

[thisweekinlinux]

@enduser64 Check out my video titled "Ask TWIL: How to Make a Screencast on Ubuntu / Linux". You need to convert it from .ogv to another format. DeVeDe can also convert it.

[TableWolfMusic]

@thisweekinlinux Normalise raises or drops the volume to the standard level used in the music industry such as o an audio CD that you'd buy or an iTunes song you buy etc. There are 2 types of normalise. The first just bumps everything in the audio up (or down) to the industry standard level. The second type stretches it all so if, for example, the volume was initially too quiet, the peaks & troughs would be proportional once normalised. This way you can keep very quiet bits, followed by the max.

[thisweekinlinux]

@TableWolfMusic Hmm. perhaps I need to try out Normalize then...

[TableWolfMusic]

@thisweekinlinux Hi! I sent you a message. I hope you think it is cool. You've so got to see the "This Week In Linux" pictures.

[enduser64]

Thanks for your videos.

I have a problem: when I add an OGV file (from recordmydesktop) to KDENLIVE, it appears white and I can't edit it. changing the project's properties (according to the OGV file's properties) does'nt help.

do you know how to fix it?

[thisweekinlinux]

@enduser64 You'll have to convert the OGV to something Kdenlive can use. Check out my video on Creating a Screencast in Ubuntu / Linux. It has an mencoder command in the description you can use to do it. Alternately you can download DeVeDe to convert the file to DivX / Mpeg4

[QueeeeenZ]

can't wait to see how to use the blue screen effect!

[thisweekinlinux]

@QueeeeenZ Since I'm going to be out of town on Monday, I actually started shooting the video today. I'm going to see what I can do to post it remotely, but the worst case it should be up by Monday night at the latest.

[OwNaGeOfDaLiAm]

Great video! Thumbs up :)

Can I just ask, what do you use Ubuntu for and why do you prefer it over Windows?

[thisweekinlinux]

@OwNaGeOfDaLiAm Thanks a lot!

At the moment I use Ubuntu as my main video editing / audio editing / screen capture workstation. On my laptop I have been moving around between distros a lot lately, but I use it for watching YouTube videos, Hulu, some website work, occasionally video editing. Just general stuff. I haven't found much that I can't do with Linux at this point... :)

[TheMichaelBender]

@thisweekinlinux ..I like your reply to..OwNaGeOfDaLiAm...i feel the same..

[FenderGibsonWashburn]

I've been editing my videos with Kdenlive for months now and yet you still showed me a couple things I didn't know. Thanks! In the video I finished today I used 3 layers. 1st layer was cropped and moved to the bottom of the screen with composite. 2nd layer used green screen and composite to show the 3rd layer as the background. Plus I used normalize on the audio. All rendered at the same time perfectly.

[thisweekinlinux]

@FenderGibsonWashburn Very cool! I'm glad you've had such good luck with Kdenlive. It's a very powerful tool.

[vwbond]

Thanks for teaching...really. Before finding out about kdenlive, I don't know how to make good video editing in Linux. Go Linux Go

[thisweekinlinux]

@vwbond Awesome! I'm glad you guys are getting something out of these. :)

[russjr08]

Thanks, great vid!!

:)

[thisweekinlinux]

@russjr08 Thanks a log man!

[ThingsontheWeb]

Compiz-Fussion

thisweekinlinux

sliced bread

[thisweekinlinux]

@ThingsontheWeb hah, thanks. :)

[21StuB]

Great tutorial, please keep them coming!

[thisweekinlinux]

@21StuB Thanks very much! :)

[EnavSounds]

Installing blue Screen plug-in......... pleas insert WindowsXp CD

[thisweekinlinux]

@EnavSounds hah, nice!

[Radminster]

yeah!!!, I want to know how probably to make that blue screen cut and montage, wait for next video man, thx for this also :)

[thisweekinlinux]

@Radminster Montage? Not sure exactly what you're looking for there. Let me know and I can throw that into the next video as well.

[Radminster]

@thisweekinlinux I mean this stuff ;) youtube / watch?v=O-XmhvpdN40

[thisweekinlinux]

@Radminster hm, looks like they just showed how to do the normal blue/green screen thing. That's exactly what I'm planning on covering next time. :)

[Radminster]

@thisweekinlinux THUMBS UP :D

[SuperKittyPancake]

Everybody GO TO HIS WEBSITE AND VOTE FOR GENTOO.

If you pick it, TWIL will contemplate suicide! 8)

[thisweekinlinux]

@SuperKittyPancake I shake my fist violently at you... but if the people want to see it, I'll make it happen...

[SuperKittyPancake]

@thisweekinlinux

I just want to see if you are capable to work with it. You seem like a Linux 1337sauce. We all know that you will have some problems. :)

[thisweekinlinux]

@SuperKittyPancake oh I can assure you I'll have problems with it. but I'll do my best when the time comes.

[sosroli]

what would happen if: ubuntu is installed on a hard. that ubuntu is used for lots of things, but one day, i choose to install that hard in another PC and use ubuntu there. will it work? any errors will happen? data will be safe?

and if after that i choose to put it back to its original PC:

will it work? any errors will happen? data will be safe?

thx

[thisweekinlinux]

@sosroli it should work decently. The only problem I could foresee is any special hardware, like wireless cards and graphics cards. The rest of it should autodetect normally. The data itself should be just fine.

[UbuntuHelpGuy]

Nice video, mate. I will be using Kdenlive more often after these videos. I had some problems with the program in Karmic, but haven't discovered any problem in Lucid.. Yet! xD Keep making amazing videos, mate.

[thisweekinlinux]

@UbuntuHelpGuy Thanks very much! Right back at you. :) You've made some great tutorials.

I've used Kdenlive in Karmic, Lucid, Fedora, and Arch at the very least, and while it's buggy, it's still the best editor I've ever used.

[metalmaniac248]

that speed removing the audio thing is quite annoying, i had to pull the audio out of my video clip and change the speed by the same factor as the video in audacity then put the altered audio back in, :|

[thisweekinlinux]

@metalmaniac248 I did some reading on the Kdenlive forums a while back, and apparently that's a limitation of MLT. It's inconvenient, to say the least...

[thejoesteiger]

Can you go over the blur effect? so I can blur out my email address and stuff, not the whole screen though

[thisweekinlinux]

@thejoesteiger for something like that you would want the Obscure effect. it creates a box that you can resize and move around to cover up items that are sensitive. It is not keyframeable though, so once you put it someplace, it stays there until the clip ends.

[jackrok]

Greate Video Mate.

I didnt know about this program.

Thanks

[thisweekinlinux]

@jackrok Thanks very much! :)

[Laoch111]

Very in dept coverage. Thanks.

[thisweekinlinux]

@Laoch111 Thanks very much! :)

[necroking14]

why dont u use sony vegas

[thisweekinlinux]

@necroking14 Vegas is only available for Windows. This is a Linux channel, so it only makes sense that I use Linux-based software. Kdenlive is one of the best video editors available for Linux, and it's free. :)

[necroking14]

@thisweekinlinux yeah good point. i just mean virtual boxing windows with sony vegas cuz sony vegas is better. but linux is still the best

[thisweekinlinux]

@necroking14 Nah, not interested. Thanks for the suggestion, though. If this were not a channel devoted to Linux, I might be using something different, but it would be hypocritical of me to make videos about Linux using Windows or Mac software. :)

[necroking14]

@thisweekinlinux true true

[relampago21]

I mean part 5, my mistake!

[thisweekinlinux]

@relampago21 No problem. I have trouble keeping up with the numbers myself sometimes. :)

[relampago21]

Kdenlive is a great piece of software, it is the program I was looking for

[thisweekinlinux]

@relampago21 Wonderful! It's definitely not perfect, but it's the best / easiest I've found with all the features that I need.

[relampago21]

@thisweekinlinux yes it has still some bugs, but it is the best software I have ever used with my oldskool sony HI8 :D

[thisweekinlinux]

@relampago21 Exactly, same here. It's one of the first video editors I tried, and it's the best one, so every other one I use I compare to it.

[relampago21]

@thisweekinlinux waiting for Part 4 :), thanks again for sharing!!!

[minoc2]

You do a really good job presenting these.... I look forward to the next one.

[thisweekinlinux]

@minoc2 Thank you very much! I think next week's might be the last one of these, because after you learn Compositing it's pretty much just putting it all together.

[minoc2]

@thisweekinlinux I have a suggestion - film (or record the desktop) as you prepare to do one of your normal presentations, and then add an audio notation and share this as the 6th and final vid. If it is a bit longer, and not well edited, no problem. What it would do is help show "how to put it all together" really well.

Again, really good job.

[thisweekinlinux]

@minoc2 That's actually an awesome suggestion, and something I was considering when I mentioned putting it all together earlier. :P Thanks!

(someone else had suggested doing a video on how I sync my audio and video, but doing a "putting it all together" would take care of that)

[commodore256]

5:29

If you want some Blue Screen Video, use Windows. ;-)

[thisweekinlinux]

@commodore256 d'oh! /facepalm. I guess I set myself up for that. I kept switching between Blue Screen and Green Screen. I don't know why Kdenlive doesn't just call it Chromakey. I guess that would confuse people.

[KreKeriS911]

thanks for another good video ;)

[thisweekinlinux]

@KreKeriS911 Thanks! :)
