Linux Video Editor Cinelerra 1.0 Released

Ogerman writes "At long last, Heroine Virtual's Cinelerra 1.0 has been released. This successor to the discontinued Broadcast 2000 project is absolutely amazing and should give Adobe Premiere and others a run for their money as it continues to mature. So, fire up those digital camcorders, get to work on all your latent indie-film ideas, and help put ol' Jack V. out of a job. Here's the 1.0 Press Release." For those unfamiliar with Cinelerra, check out the screen shots.

Yet another video app that ignores audio...

[Theaetetus]

First, let's start with the non-flamebait part: it's great to see another relatively cheap video editor out, as it puts filmmaking ability into the hands of the masses rather than just those able to afford $20k+ Avids.
iMovie and iDVD don't count, 'cause those are really just toys for making home movies or submissions to iFilm, but Final Cut Pro is/was a great competetor to Primere, with all of the features at less than half the price.

However, I'm an audio professional, and will happily and uniformly disparage all of these 'tools' for neglecting to have any real ability to edit audio. As just about anyone in the industry will tell you, audio is the bastard stepchild of video/film, with less than a tenth of any movie's budget spent on sound... and yet all of those same people will agree that sound is just as important as visuals, if not more - consider the Blair Witch Project, with cheap, shoddy visuals, but eerie and compelling audio to create the mood... Now imagine a rock-steady camera in a high-budget film, with sound that sounds like cheap vinyl... or even AM radio... It's just not acceptable, and nothing will alienate your audience sooner.

As an example of the downplay of audio, Digital Video Magazine has an ad in the last issue offering a turnkey video editing system... Dual 1 GHz G4, Final Cut Pro2, 80 GB Firewire drive, Superdrive, Firewire Media Converter, Sony's $5000 prosumer digital camera, 23-inch Apple LCD cinema screen, Sony 19" NTSC reference monitor (>$1000!), and... Harmon Kardon SoundSticks!

$20,000 USD for this system, and you're getting a $150 pair of speakers... which, frankly, suck (I just wrote an article to be published in December about those speakers, after running them through tests of frequency response, distortion, noise level, etc., and you'd do better with a $150 pair of headphones... but they aren't as pretty).

Additionally, none of these programs have the ability to scrub audio, a MUST as any real audio editor will tell you, very few of them will let you edit on a resolution smaller than a frame (30 fps means that 1 frame = 33 ms... However, a 5 ms delay is audible as phasing, and as low as a 25 ms delay can be audible as a distinct echo), most of them have linear VU meters (rather than logarhythmic, like our hearing... consider, with 0 dB FS as the top of the scale, -3 dB FS is half the power, and on a linear meter, half the distance down... However, -3 dB is a difference in level that is really only noticed by trained ears... Additionally, the SMPTE standard for digital audio is to have normal level (0 VU) at -18 dB FS... Or almost off the scale on any program with linear meters... That's freakin' insane. As a comparison, try using Photoshop with the brightness on your monitor turned down to almost 0. You're trying to work reasonably at the threshhold of noise of the system you're working on.

Also, the EQs in most of these programs have their frequency range set linearly, too... Human hearing goes from roughly 20 Hz to 20 kHz (roughly - young women and children can frequently hear higher frequencies, usually topping out by 23-26 kHz), but our interpretation of frequency is logarythmic: the top octave goes from 10 kHz to 20 kHz (or, the top HALF of a linear scale). The next octave (or, the next lowest quarter on a linear scale) is from 5 kHz to 10 kHz...
You don't start getting into useful ranges until you're in the bottom 32nd of the scale, from 500 Hz to 1 kHz - the fundamental of the human voice goes from about 125 Hz to about 500 Hz, most of the vowels and formants are from about 500 Hz to about 1.5 kHz, and the consonants are from about 1.5 kHz up to about 4 kHz (for the sibilants). There's very little energy in the human voice above 5 kHz... So have fun setting your EQs properly when you're looking at a linear scale that emphasizes the top two octaves... ABOVE what you're dealing with.

Then again, the two major audio editing software programs on the market, ProTools and CoolEditPro also miss some of these, so I guess I shouldn't complain too much. When you deal with sub-standard tools everywhere, you have to give up some expectations

By comparison, look at the Orban Audicy (used in most radio stations for production), and the Fairlight Merlin and D.R.E.A.M. Stations, used for most film/television production.

Sorry. :)

Friend, everything you said is perfectly valid, but... video finishing is not audio finishing. Fire, DS, EditBox, et cetera are not audio finishing equipment. They have audio input and output capabilities, of course, and you can mix tracks and whatnot. But that's just for scratch audio. The real audio will get mixed and laid down by an audio professional in a ProTools (or similar) suite after the editor finishes the video.

Basically, the reason why nobody cares about audio in video editing software is because the guy doing the video work is never the same person as the guy doing the audio work. Instead, it's two different people, both highly trained professionals, with totally different areas of expertise.

Now, if you want to complain about how a particular audio finishing program is inadequate, be my guest. But complaining about how video editing software is a bad audio editing tool is kind of like complaining about what a poor job your screwdriver does of carving your Christmas goose.

I use the Wintv GO Hauppuage card and I can record tv shows with mplayer, xawtv, and vcr,

I like vcr the best because it has timed recording.

Here is a example:

vcr -g /dev/video0 -c 'divx ;-) low-motion' -v -p 38 -F 30 -q 100 -m mono -b 64 -t 32m tv-show.avi

-g is to set the device (my wintv card is /dev/video0)

-c 'divx ;-) low-motion' is the video setting

-v is for verbose

-p 38 is the channel to record

-F 30 is the frame rate

-q 100 is quality and its set to 100 which is best

-m is to set mono or stereo

-b 64 is the bitrate for the mp3 audio (64 is perfect for mono audio and 128 and higher is good for stereo)

-t 32 is the timmer, I have it set for 32min

and last is the file I am saving it to, which is tv-show.avi

Hope this shows you how easy it is.

Plus you can stick vcr in your cron tab to record tv while you are away.

vcr comes with most distros.
