Hi,
short: saving a screen recording with MPEG ASP (Xvid) and container AVI or MP4 results in a noisy video. Which options in avidemux can I use to prevent that?
@added: running xubuntu 12.04, 64Bit, Avidemux 2.5.4
That's what I did and want: I recorded the screen in ubuntu with "recordMyDesktop" to a ogv file. I converted using "Handbrake" because otherwise mencoder or avidemux are deleting double frames, I receive a m4v file. I read this file by avidemux and can play the recording. No noise so far, wonderful! I cut the video using the "cut"-filter within avidemux and I us MPEG ASP (Xvid) and AVI or MP4 container. I save it and the result is noisy and grows in size! By the way: videos taken with my camera with real persons and so on become NOT (!) noisy using this codec and container (and standard settings in avidemux). My aim is to make a video clip with both, recorded desktop video and a camera video with persons. So I have to join the two different sources after cutting, adjusting fps, ... That works fine'so far, but screen recording becomes noisy. So: which options within avidemux are responsible for noise generation of screen recordings? I need to turn off noise.
thank you

Please delete your post in Windows section your running on Ubuntu. Your flavor of ubuntu and is it 32/64-bit?
Version of avidemux used?
Check your preferences and unmark in Tab [Video]:
[ ] Horizontal debloking
[ ] Vertical deblocking
[ ] Deringing
see if this helps?
Have you other possibilities regarding the format used for recording with recordMyDesktop? experiment with those?
I added ubuntu and avidemux version information in my first posting. The windows thread is removed.
I unmarked horizontal und vertical deblocking. Deringing was already unmarked. But it didn't help :(
The file size raised again about 30%. But thx for you help.
Any other ideas?
Yes try avidemux 2.6 build for ubuntu 12.04 64-bit found here: avidemux Cli/QT/GTK 2.6 64-bit deb download ubuntu 12.04 LTS (http://www.avidemux.org/smf/index.php?topic=10584.0) these start from terminal box.
Try recording with the same frame rate as the target video?
I use(d) Kazam screencaster, but currently it crashes here.
I downloaded avidemux3_2.6.0_64bit_r8136_12.04_debs , I installed the gtk-version with all filters and add-ons ...
and it WORKS!
No noise with default settings/options in avidemux3. Great! thank you Jan!

If you use QT with avidemux3-plugins-QT4, probably need to uninstall avidemux3-plugins-GTK-2.6.0-7xxx-Linux. More stuff in there is working then GTK. Developers have been very busy with 2.6 last months, weeks and days. Looks nicer every day. Can no longer miss this tool.
I installed GTK only. Both versions 2.6 GTK and 3.0 GTK are now installed - and I need both versions because the select tool of 3.0 doesn't react. I can't cut sequences or copy them and paste. So I need the version 2.6 further on. I hope I need 2.6 only in this case.
When I use 2.6 again on a file the noise appears again. But cutting something or pastings something in 2.6 and then saving "copy" without filters allows to keep the video without noise :) So I can work in combination both versions 2.6 and 3.0.
BTW: v3 can't be closed with the "X" of the window manager. It can only be closed with the avidemux menu.
