[edit] Import
For capturing DV it is recommended to use Kino, since Cinelerra focuses on editing.
- sudo apt-get install kino
[edit] Edit
Cinelerra, the most advanced non-linear video editor for Linux, works very well with Ubuntu, especially the latest release. You can install the unofficial cv build by adding these repositories.
Cinelerra should guide you through making some necessary changes to you installation. Please make sure you have suited versions of Ubuntu and Cinelerra. (E.g. for me, the AMD64 didn't work, so I tried the i386 version which runs smoothly on my setup.)
You should also have a look at this Cinelerra tutorial.
[edit] Tip & Tricks
- As goes for most very advanced programs, a lot of frustration can simply be avoided by reading some documentation, before you dive into using the program.
- Should Cinelerra crash, you can always reopen it and simply choose "Load backup" from the File menu. However, please note you need to do this immediately after reopening it! Cinelerra saves every operation, including moving the needle.
- When u start a new project, remember to check whether it is in the PAL or NTSC format!
[edit] Export
A more comprehensive overview of formats you can choose to encode your files into is available on the Video Formats page. Below are some very basic Ubuntu-specific instructions to get you started for a select few.
[edit] MP4
To produce high resolution .mp4 files that are ideal for podcasts and work very well with iPods, iTunes and Miro follow these steps:
- install ffmpeg from the medibuntu repositories
- install pypodconv following these instructions
- type this on a command line: pypodconv -i ./testfile.avi -o ~/testfile.mp4 --hd -b 1500
- if your source is interlaced, you can deinterlace it by adding the following option to pypodconv: -deinterlace on line 73 after 'ffmpeg -y -i "%s"
[edit] FLV
To produce small flash video files, that are well suited for embedding in webpages, e.g. for use in conjunction with this free player, you can follow these basic instructions:
- install ffmpeg from the medibuntu repositories
- type this on a command line: ffmpeg -i ./testfile.avi -acodec mp3 -ar 22050 -ab 64 -f flv -b 600 -s 480x360 ./testfile.flv
- if your source is interlaced, add -deinterlace to ffmpeg flags
[edit] Ogg theora
If you are interested in open source codecs, the Transmission network, whose objective is to make independent online video distribution possible using FLOSS software, has undertaken a research project on this topic on their wiki.
- sudo apt-get install ffmpeg2theora
- ffmpeg2theora -p preview -o ./testfile.ogg testfile.avi
