Re: [CinCV] Ducking audio
I am trying to setup ducker using Cinelerra's audio Compressor effect. I want to compress/limit a music track using a voiceover track as a trigger. To do this I have to put the voiceover track number in the Trigger text box. The voiceover track is sixth from the top, does that make it track number 5 or 6? Or is it 1 or 2 because it is the second audio track? Or should I put VoiceOver in the Trigger text box because that is the track name? I set up the compressor graph with a "knee" at -10db so that any music under -10db gets thru untouched while everything over -10db is hard limited at -10db. And because the voiceover track is the trigger this should only happen when the voiceover level exceeds -10db. But the compressor seems to be always on regardless of what is happening on the trigger track.. Any ideas? And apologies for answering myself. >Is there any way to duck audio in Cinelerra? I want to have a voiceover audio track control the volume of a music track, ie. the music volume is reduced when someone is talking. I could do it by exporting audio tracks to Audacity or Ardour, and then importing the effected tracks back into Cinelerra, but I would like to do it in Cinelerra if possible.

[CinCV] Re: Problem compiling Cinelerra on Ubuntu Hardy
Well, I don't know what fixed it, but I now have good playback _and_ ffmpeg works via yuv4mpeg stream! Woohoo! The last few things I changed for the record: 1) downgrading to the version of ffmpeg in the ubuntu repository. This was version 3:0.cvs20070307-5ubuntu7.1+medibuntu1 2) reinstalled everything I had installed via akirad repository. These are: akirad-keyring-and-mirrors, akiradnews, cinelerracv-gl, libgavl1, libguicastcv-gl, libmpeg3cv-gl, libquicktimecv-gl, optlibx11-noxcb-6, optlibx11-noxcb-data, libquicktime1, libquicktime-dev, quicktime-utils Thank you so much for all your help guys!

I was banging my head against wall for quite some time - every yuv4mpeg rendering consisted of garbage. Finally, I just rebuilt Cinelerra by disabling external-ffmpeg and now everything is OK. By superficially looking at git's log output (not familiar with git at all) I suspect the problem might be with the following patch: commit 954a91e72bba1ed1ce641b5faee7d4c5f318c074 Author: David Arendt Date: Sat Dec 27 12:02:20 2008 +0100 Add support for the dnxhd codec. In order to use dnxhd, a recent ffmpeg should be intalled and cinelerra must be compiled with ./configure --with-external-ffmpeg (cinelerra can also be compiled with builtin ffmpeg only dnxhd can't be decoded) Only decoding is handled by this patch. Encoding dnxhd can be done using YUV4MPEG Stream and using the following pipe: ffmpeg -f yuv4mpegpipe -i - -vcodec dnxhd -b 115Mbps %. Remember that dnxhd can not handle every resolution. All tests have been done with 1080p50. Can someone confirm that disabling external-ffmpeg solves the problem?

Re: [CinCV] DVD longer than half an hour?
Hi Ron, Here's what I do, I hope it helps. I generally create a DVD with 6 or 7 different clips that I output from Cinelerra as Raw DV files. I add up the total running time of all the clips (the one I'm currently working on is 6 clips totalling 71 minutes). I take that over to http://www.3ivx.com/support/calculator/ and input the size of the disk I'm going to use (4200 MBytes), my running time (01:11:00), and my audio bitrate (256 KiloBits/sec). The calculate button tells me I can have a max of 7820 kiloBits/sec. I then create a shell script to run through all of my clips in succession using 2 pass encoding like: ffmpeg -i clip01.dv -pass 1 -passlogfile log01.txt -target ntsc-dvd -aspect 16:9 -b 7820k -maxrate 8000k -ab 256k -ar 48000 -ac 2 01_output_pass1.mpg ffmpeg -i clip01.dv -pass 2 -passlogfile log01.txt -target ntsc-dvd -aspect 16:9 -b 7820k -maxrate 8000k -ab 256k -ar 48000 -ac 2 01_output_pass2.mpg Note the "-b 7820k" I took from the website. This has never resulted in files too big to burn onto a disk and it seems to get very close to the file size limit for a DVD. I'm sure there may be other ffmpeg switches that would help me with better quality, I'd love to hear input from anybody. But, I've been generally happy with the quality and it's pretty much a cut and paste operation at this point so I haven't been experimenting much.

Re: [CinCV] DVD longer than half an hour?
Ron, That's good to hear. My big question, still outstanding, is: "HOW do we control the size/rate of those .mpgs?" I believe that neither dvdauthor or dvdstyler will add much overhead, nor should they make the .mpgs any more compact. But, when rendering in Cinelerra, and when combining in ffmpeg, the only parameter that seems to bear upon size and bit-rate would be the -target option. Do you use something different from '-target ntsc-dvd' ?? (BTW: For Cinelerra rendering, I use the ffmpeg pipe: "ffmpeg -f yuv4mpegpipe -i - -y -target dvd -flags +ilme+ildct %") Unless you (somebody) have applicable experience, I guess I'll just futz with the ffmpeg parameters to see what happens.

Re: [CinCV] xml into .avi or .mov
Rendering as you say I get the following error message: virtual int File DV::open_file(int, int): Raw DV format does not support following audio configuration: 0 channels at sample rate: 48000Hz But if I render it after ticking both "render audio tracks" and "render video tracks" it does so. After that I tried to render the Raw DV into both '.avi' and '.mov', and it does so, but the quality is just as awful as without rendering to Raw DV first. I read something about having a audio video set into two complements 16bits (Pcm) in order to have a video render into '.mov'. I'm not so sure if I'm interpreting it right. Would that be the problem here?
