Falk,

I'd like to try my hand at making a screencast of mx44, using XFCE (you wrote above that this is possible now). After I add the scripts, what commands do I use?

Thanks,
brian

Just follow the steps on the first post, using 'xrec_1 xfce4' instead of kde4.


Ok, thanks. I'm crossing my fingers! :D

I also need to know:

you wrote that the audio and video are saved separately. Do I have to load them into kdenlive (or similar) and sync them together manually? (I was hoping I'd have a finished product automatically.)

brian, be happy with the need to use kdenlive! You will find that there are lots of easy places to take a minute deleting useless gaps or just fine-tuning most of the time. It is worth it to preview in kdenlive before committing because you'll end up with a better result. That was my experience anyway.

Hi guys,

I had installed "Record it now" a while back, and after opening it earlier, it now won't leave me alone. I rebooted and it appeared after login! :shock:

If I remove it, it says that it will also remove "kxstudio meta all" and "kxstudio meta video" and install "record my desktop" instead.

What should I do?

Ok, I killed it, and I feel really bad. :cry:

I made the screencast, although one of the two terminals complained that it couldn't run in realtime and that I should have done it as root. ???

Anyway, I have an audio file and a video file now. I logged in in KDE, since kdenlive didn't open in xfce before..

I put the two files unto two tracks at the bottom, and they play, but I can't see the video as it progresses. Any quick tips on making this vid? (All I want to do is remove the first minute or so.)

Then at the end, I hit "render" and it makes a complete video with audio, right?

Your project profile MUST be set as a 720p variant, so it exports correctly. (see my notes on youtube presets on 1st post).

Maybe you should watch some kdenlive tutorials too.
It may look simple, but kdenlive is a very powerful tool.


Yes, I set it to 720p at 25/sec (I can't remember exactly, but 720p was selected.)

I'll look at youtube a bit first. All these learning curves! ...

You might want to set a higher buffer-size and cpu freq to max when recording. xruns will break the AV sync.

The first post was updated with related info.
Feedback is welcome.

and btw, you now have no more excuses to not make videos! :lol:


Falk,
were the updated scripts automatically given in the repos, or do I have to download them somewhere? I'd like to get back into screencasts again now that it should be a bit easier.

Thanks!

Just tried this but launching ardour from Claudia opens outside the recording window. I can see the connections ... Just not the app.

Is there a better way to do this?
Cheers
Barney

You can also now just use Simple Screen Recorder which is a new easy-to-use program!
