[CinCVS] Mpeg2 encoding
Hi everyone This is my 1st post on this list and I'm hoping that you may be able to help me. I have Cinelerra installed and working well. I have read as much as I can on the net but I am stumped on a few topics but the 1st one 1st. I am trying to render from the timeline to an Mpeg2 Video file. I am using the standard DVD settings in the Video rendering gui. But when I go to start the render, I get the error on the terminal that the mpeg2enc.plugin cannot be found in /usr/lib/cinelerra/ I found the plugin in /usr/bin/ and copied it over and everything seemed to work. But in reality, nothing seems to happen at all. I don't get any errors but after many hours the render completion figure remains on 0% Can anyone help me on this or suggest what I could do please?? Thanks very much in advance Vaughan ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

Re: [CinCVS] Mpeg2 encoding
I don't think that's the case. There are two ways to produce DVD compatible MPEG-2 output through Cinelerra. The easiest way is the mpeg2enc plugin. If you copied the mpeg2enc binary from /usr/bin to /usr/lib/cinelerra, you're almost there. You need to make sure that the file is named mpeg2enc.plugin in the cinelerra directory. If that doesn't work, try posting the exact error message you are getting.A second way to get mpeg2 video is to render to a pipe and let ffmpeg do the work. There is a preset for this in the render dialog. ffmpeg can be 40% faster than mpeg2enc, though the quality is typically lower. As a matter of practice, I use ffmpeg to render 'snapshots' and rough cuts, then mpeg2enc to produce my final video.

Re: [CinCVS] Cinelerra on Ubuntu
Raffaella, I also had some problems getting Cinelerra to work on Ubuntu 6.06. You can check out my blog post with a link to the solution that worked for me here: http://www.thesourceshow.org/blog/1 Hope this helps!

I'm starting to assume that something is not working properly. Can it be that Cinelerra HV is made for Fedora and not for Ubuntu? Do you suggest to install Cinelerra CV instead? Hi Rafaella, Cinelerra is not made for a specific distribution. I saw people here using it on Slackware, Fedora, Gentoo, SuSE, and I am on Debian (you probably know that Ubuntu is a derivative of Debian and uses the same package manager). Do you know the Wikipedia entry on Cinelerra? Pierre Dumuid recently added a paragraph on the two different Versions of Cinelerra there: http://en.wikipedia.org/wiki/Cinelerra#The_Community_Version Many of us here (including myself) are using the CV-Version; this version gets additional Fixes and small improvements over the time, so /we/ believe it to me more stable and usable. You should note though, that from time to time, when there are larger modifications, it can get more instable. So it's probably a good idea to have a look at this mailing list in order to know what's going on. Recently, there was a new Version (2.1) released by HeroineWarrior. The Community just started to integrate this changes into the CV-Version, so you can expect some destabilizing of the CV-Version for some time in the Future. So I would advice everyone not immediately interested in the new Features of HV-2.1 to stick to the last CV-Version before this transition until you see people positively reporting they are successfully using the upcoming new CV-Versions. The Community-Verson uses a Version Management Tool called Subversion to manage the different code versions. The aforementioned last 2.0-CV-Version has the Revision Number 836 in the Subversion. At http://www.kiberpipa.org/~minmax/cinelerra/builds/sid/ you will find Debian Packages of the CV-Version, the last beeing from 6.Jun.2006 See also: http://cvs.cinelerra.org/getting_cinelerra.php Reuben Firmin just wrote an Blog Article comparing Cinelerra and Main Actor. In one of this entries he covered the Installation of Cinelerra-CV on Ubuntu, probably of some interest to you http://flavor8.com/index.php/2006/07/15/mainactor-vs-cinelerra-installing/ Raffaella Traniello wrote: These are my problems: 1. Randomly (1 out of 10) the compositor is dark (no image, sound only). There are no disabled buttons in the patch/control area. This sounds strange, like a bug. To help more, it would be necessary to know what media format you are using (DV-Avi, raw DV, quicktime, mpeg ts...). 2. Double clicking between two labels on the timeline doesn't highlights the region between the labels. Instead it highlights the whole edit I'm clicking on. Yes, that's the way cinelerra does this... If you want to select the range between two lables: click at one lable and then shift-click on the second. You could enter values into the position-display in the status line as well in order to select a very precise range (e.g. 3 Frames). And another very important command for editing is the paste silence from the edit menu!! 3. Trimming: when I move the cursor I don't see the changing in the compositor window. It keeps showing the same still image and I can't decide the extent of my trimming. Yes, that's a well known shortcomming. You have to utilize lables as a workaround... Hint: you can move the locator by single frames using the numpad keys. 4. Trimming: sometimes (randomly?) when i drag the margin of an edit in the video track the audio track won't follow. All the tracks are armed. In this way I miss the match between audio and video in the edits. Make sure you have selected the align cursor to frames in the settings menu. Cinelerra uses a trick to keep sync between audo and video: the edit actions manipulate /all/ clips on all armed tracks /which start at exactly the same position/. If you don't align cursor to frames, then the audio clip can start on every location in between frames. You can see this effect by zooming in to the level of single frames. One last question: How can I split and edit in two on the timeline (trimming)? This one is surprisingly difficult (or am I missing something obvious??) You can select a part and cut it away (to clipboard), but if you re-insert it immediately, cinelerra will automatically join it together to be one single clip again. (Unter certain other circumstances this behaviour is helpfull, but here it's rather not). But you can always paste the part cut off on a different location. For trimming you use the mouse at the border of the edit. It is important to note from wich side of the cut you are aproaching. The three mouse buttons by default have different

[CinCVS] Audio Clipping in RAW DV
I am having some trouble rendering to RAW DV. The video looks fine, but I have some clipping in my audio. I get a clip about once a second. Has anyone seen this before or know how I should start narrowing down the issue? Rendering to other formats like Quicktime for Linux or Theora works fine with no clipping.

The problem is intermitent static and is not known to relate to specific formats or settings. It began occurding when the DV render code (which never worked) was being repaired. The job was not quite finished. It was reported to Richard Baverstock who was doing that work. He agreed there was a problem but obviously has had no time to fix it.
