Linear Video Editing Software for Mac?

Cliff posted more than 9 years ago | from the editing-without-post-production dept.

Movies 76

Vilorman asks: "Everyone knows that there is tons of linear video editing hardware out for Windows and Mac. There is even quite a bit of stand alone linear editing software for Windows. There are all of these Firewire DV input/output boxes on the market but where is the software for them? We've got Final Cut Pro HD and DVD Studio for the Mac but that's all non-linear. Where's the linear stuff? I want to be able to take live video into my Mac and superimpose text over video or images over video and then send it right back out using the standard Firewire video I/O box that I already have; but I want to do it live on the fly, not in post-production where I have to ingest an hours worth of video and then print it back to tape. I know it can be done but where is the software for making it happen?"

Re:first of all... (4, Insightful)

TheWanderingHermit (513872) | more than 9 years ago | (#10184756)

I think that's it -- he definitely has his terms confused. Linear editing is when you have to start with the first scene and add one scene at a time. Non-linear editing is when you can edit the scenes and shots in any order.

He is looking for a live keyer or character generator (as you say, real-time).

There are many machines that do that. Basically he wants a switcher, not a computer. But I hear you can still use an old Amiga 2000 like that.

You know, when people are doing "Ask Slash-Google" it would really help if they reasearch their terms so they know what they're talking about before they ask a question.

There's an Amiga 2000 Video Toaster in the showroom at WeirdStuff [] (Sunnyvale, CA) for, I believe it was, $299. It looked like it was in good or better condition, though honestly I don't know much about it, so I can't really tell anymore about it.

Re:first of all... (2, Interesting)

Bastian (66383) | more than 9 years ago | (#10197630)

It was a hardware device that allowed you to do realtime video editing. I'm not sure of all the features, but our system allowed you to do realtime fades between two video streams. The software integrated well with Lightwave 3D, so you could also insert 3D objects and animations into a video stream on the fly.

At the time, an Amiga was the only way to go due to some hardware issue. I think it was that there was some sort of issue with the clocking of a TV signal that was much more difficult to solve on PCs and Macs than it was on Amigas.

Anyway, Amigas did the job so well that the Preview channel supposedly ran on nothing but aging Amiga 2000s with Toaster cards up until when they were bought out by TV Guide.

Ohreally_factor (593551) | more than 9 years ago | (#10203738)

Well I was going to use some mod points here, but couldn't resist chiming in on video toaster. I wasn't an amiga user, but I was a RAVER! in the SF bay area in the early 90's (hello sf-raves, brian behlendorf, et al, superhigh comin back atcha). All of the good parties included visual artists, and the predominant medium was a video toaster set up. I remember fondly zoning out on huge projections of trippy graphics, and none of this was "taped" these guys were up there mixing live, and it was way ahead of its time to be running on a lil old amiga. These projections looked great, and the operators would be reacting to the live dj's and do their fades, transitions, effects to the music or rhythm. It was a great integration of sound and light. Seems like there hasn't been anything new in this vein, wonder what happened? any video artists care to respond? I have always been curious about what they did, but didn't know any of them personally.

Another cool program, but for the atari ST, was the Trip-a-Tron, but I never saw that used for projections, and it was more for just generating trippy graphic patterns and stuff.

there is a little known company from Troy, New York (yup, RPI alumni) called Vidvox that makes real-time video software for editing, effects, whatever. Educators are even using it to do presentations over powerpoint, since it does pdfs, pictures, and video all from one simple interface. Traditionally the software has been used, and was originally designed for, video artists or VJ's. Now they have expanded their focus to include video production work so as real time editing, visualization and storyboarding. It even exports EDL so you can load what you play directly into Final Cut (or whatever) to fine tune a rough live mix.

Check them out at, and their new release of their flagship product, Grid2. The crazy part is, it's only $75 and does up to HD quality!

Well it's not Mac and it's not using Firewire, but it is digital.

Compix Media [] produces boards and computers that allow real time keying (with alpha) of graphics or text. The software is pretty easy to use and allows crawls, scrolls, and regular animation of pages. The higher end versions use SDI (Serial Digital Interface) for video i/o, while the cheaper versions use s-video and composite video (BNC) connectors.

dgatwood (11270) | more than 9 years ago | (#10184945)

If all you want is a stand-alone GC and aren't trying to super graphics, get a Videonics Video TitleMaker (any version). Last I checked, they wre a lot cheaper than a Chyron. Of course, at least in the versions I've used, they didn't do graphics, and they do the keying themselves, while a Chyron has a separate key mask to drive an outside keyer built into a switcher, so if that's the desired use, go with the Chyron, or maybe a higher-end Videonics. I'm not sure about their current offerings, since I haven't bought video hardware since about 1995, give or take.... :-)

Re:A Mac is not the answer. (4, Informative)

eht (8912) | more than 9 years ago | (#10185233)

Or a Pinnacle Systems Deko product, or a Vizrt box. If you're looking at a Mac for video editing for religious or political reasons, be aware that both Dekos and Duets (Chyron's CG product) run on Windows, thou8gh older Chyrons ran on a proprietary OS, not sure what Vizrt's systems run on.

Pinnacle has much more market share, Chyron used to be huge, but now Pinnacle runs 45% of the CG market, Chyron, Vizrt, and a few smaller players split the other 55%, so that may also be taken into consideration.

Also these systems run in to the easily multi thousands of dollars, $45k+.

Other than price though, what it sounds like he wants is definitely a CG.

Absolutely. Even an Amiga 2000 machine with a video toaster (or other genlock devices) would be a great choice.

It really doesn't matter that the Amiga is older technology. THIS is what it was designed to do, and it does it well. It will always do it well, at least as long as people are using NTSC or PAL video with RCA/BNC-compatible video I/O connectors!

VDMX and VideoScript (5, Informative)

First, you need to realize what you're looking for is not an editing tool, but a live production tool. Once you know this... well, insert the standard ask-google-not-slashdot comment here.

The best Mac live-video-switching-with-effects product I've heard of is VDMX [] .

You want this [] although you're probably not willing to pay for it.

I'm not sure if VideoScript [] will generate NTSC output to DV. Probably not, but if so, it's a cheap alternative.

If you're ultra-low budget, dig into the QuickTime docs. It's not tremendously hard to write a C app that pulls a live DV stream and adds some QT text or effect tracks.

Re:VDMX and VideoScript (5, Informative)

ckswift (700993) | more than 9 years ago | (#10184820)

I searched the web and was able to find a company called Black Magic Design [] that sells video capture cards for both Mac and pc that allow real time keying of graphics. At $300 USD for an SDI board and software it's not that expensive.

From their website:
All SD DeckLink models now support internal keying allowing you to key graphics over live video in real time. This is perfect for adding logos and "bugs" to live video when doing dubs of your show reel; or adding copyright and not for broadcast notices to client dubs.

Key features are controlled by an application called Blackmagic LiveKey that enables keying. This is just like switching your video capture card into a keying card; DeckLink works very differently when keying is tuned on. Graphics with alpha channel displayed on the RGB video output will now be keyed live over any video that's connected to the DeckLink video input and then sent to the DeckLink video output.

You can choose "internal key" on all DeckLink models where keying is done inside the card and you don't need to use any external keyer equipment. You can also quick key a graphic in LiveKey as well as set key levels; and allow keys to animate on and off using independently set time values.

For external keying, DeckLink Pro features 2 independent SDI outputs and genlock allowing image and key video output from the separate SDI outputs. This lets you key in outboard equipment such as production switchers etc.

I saw Wirecast at Mac Paris Expo (0)

Anonymous Coward | more than 9 years ago | (#10188456)

It was really amazing.

From a geeky point of view, it was exceptionally cool - in a nutshell: you create a scene which contains your video (or cam) in a place in 3D space. Then you create another scene and maybe have the video or cam somewhere else. Then when you're broadcasting, you just click between the two scenes and the video flys between positions. Hard to describe, but really cool to actually see in action. They were showing 3 cameras plugged in and scenes with 3 cameras in different places on screen and all three would fly around when you clicked between those scenes.

They showed other types of transitions, but that one with stuff flying around was what really caught my eye-candy eye.

Of course, in real life, you'd probably just broadcast a camera with a title, but hey, that's not what appeals to the geek in me.

Back on topic: I suppose it would do what the original poster wanted, but i've not used it yet; just saw me some demo!

You've confused linear editing (5, Informative)

HotNeedleOfInquiry (598897) | more than 9 years ago | (#10185095)

With on-the-fly genlocked effects. Two completely different things.

Linear editing is post-production editing, without the ability to randomly access a shot. In other words, you must hand cue up each shot then do an assemble edit. Non-linear editing is where the machine is smart enough to find your edit point from an edit list. Both terms come from tape editing, which is pretty much obsolete.

From the website:

" This software gives you a major function that mixes the 2 visuals into 1 visual for your live visual performance. You can add visual effetcs and texts as you need. Also, you can easily organize the video files and send the video source diretcly from your computer."

BTW this has nothing to do with linear editing (which is what iMovie does, and is basically a fancy way of editing by hooking two VCRs together and using the pause button) and nonlinear editing (Final Cut's "batch" system, which is far superior.)

Re:Motion Dive Tokyo (0)

What he's talking about is... (5, Informative)

SnowDog74 (745848) | more than 9 years ago | (#10186348)

He basically sounds like he's asking for a keyer, switcher and old school CG (character generator). Well, in that event, there's no logic behind using the firewire interface or a computer in the mix for that matter. It's entirely impractical to the cause. However, given the fact that these other systems are so outdated, finding one might prove far more costly (not to mention technically cumbersome) than even the cheapest, most basic NLE software packages today.

If what you want is on the fly keying of text, and switching to do dissolves, cuts, inserts, basic composites, etc. then look for an analog keyer/switcher and a character generator to interface with the keyer.

It makes no sense to want these things in a post-production environment over a digital non-linear editing system with a software based titler (like Livetype)... unless your interest is exclusively in live broadcasts.

The reason is quite simple.. whereas the keyer/switcher provides immediate response, the NLE provides unmatched flexibility, scalability and allows you to plan, storyboard, execute and correct your edits. Trying to do live keying/switching for what will ultimately be a taped program or go to DVD doesn't make much sense, IMO.

Why? Because whatever time you gain in immediacy, you lose in accuracy of your timing. Then you have to go back and correct, over and over again... and it's not easy unless you're a keying/switching expert... and even then, if you've mastered a keying/switching system, most NLEs do so much realtime rendering these days that you should be equally capable of quickly adapting to and using such systems.

If you aren't proficient in using NLEs for keying, switching and compositing, then you are presumably a hobbyist... or an editor without marketable skills. The time you spend trying to sharpen your live keying/switching abilities, you could be mastering the NLEs that are cheaper, actually easier to use, more agile and (if you're semi-pro or professional) will keep you employed.

Furthermore, it still takes an enormous amount of time to output to tape when doing linear editing. You forget that you still have to manually scrub, and dub in realtime... In non-linear editing systems, you won't be waiting for the VTR to physically reach each clip you're searching/scrubbing in your raw footage any time after the initial full-res capture. In linear systems, you'll have to deal with this every single time you scrub and execute an edit.

Every time you redo an edit in a linear system, you have to redub the entire edit, all the keying, switching and compositing in that edit playing back all sources in real-time in order to re-record the cahnges... rather than making a few corrections and re-rendering in a fraction of the time.

Add it all up, and a proficient NLE editor can do a Non-linear edit in a fraction of the time... and Non-linear edits are non-destructive.

Lastly, you can speed up the process even more by doing off-line non-linear editing. By using off-line, low-res thumbnails, or the default off-line inserts from batch logging (e.g. in Final Cut Pro), you are working all your edits, transitions, composites, keys, titles, etc. first in either low-res or with totally off-line clips.

Once all your edit decisions are finished, the computer only needs to batch capture the clips you've logged ONCE rather than repeatedly switching tapes, scrubbing and playing back through the loads of raw footage, to execute every single edit (especially nightmarish if you're going to break up and frequently insert pieces of or entire clips repeatedly in various places throughout the video). Screw up an edit on an NLE, and all you have to do is nudge your captured clip... rather than re-record.

It takes most people a few minutes to figure out how to maximize their work productivity from the benefit of logging and batch capturing in an NLE. The time you spend striping, indexing tapes and logging, and capturing, will be well-invested... instead of spending ten times as much time to figure out where the hell that one scene was and dub it in on a linear editor just perfectly (assuming one can do so the first time around with no mistakes).

Off-line, non-linear editing is also the standard for developing cut lists/EDLs to production houses for film or large SD or HD projects. If you have the skill to edit on the fly with a switcher, taking your time to do well-planned and structured post-production work will only result in an even cleaner final product. Mastering single-track non-linear editing over A-B style editing can also give you much of the immediacy you expect from a switcher, but in a far more versatile, totally non-destructive editing environment.

on-line editing (live tv shows etc) compared to off-line editing (editing movies etc) "Offline editing" refers to the "rough edit" stage of the editing process, where major story, pacing and rough graphic decisions are made, oftentimes with low-resolution compressed footage, so the offline editor can have as much of the source material available as possible, since this is where most of the important edit decisions are made.

"On-line" editing refers to the "finishing" stage of the editing process, where an "online editor" takes the result of of the offline edit via an EDL (edit decision list....or visually refers to, via a "window burn" timecode reference tape) , and basically pretties it up for final mastering (i.e. shot-by-shot color correction, tightening up edits, compositing, final graphics, etc etc).

In the 80's and 90's the online edit phase generally took place on a linear (ergo, uncompressed) edit system to ensure the highest picture quality. Ironically enough, the online editor often used EDLs generated from non-linear offline systems such as the Avid.

The terms have nothing to do with genres. TV shows have online and offline editors, and so do many motion pictures.

Offline/Online driven by $ (1)

This practice was developed because the equipment used for the online was incredible expensive, while the equipment for offline editing was relatively cheap. You don't want to do your creative decision making on a $2 Million machine (with corresponding high rental rates) when you can accomplish the same on $10,000 - 20,000 system, and spit out an EDL.

When the Avid first came along, it went against this model, as it was more expensive then linear offline systems. However, it made editors much more productive (and it was still cheaper than the online systems of the day), so it did represent a total cost savings.

I know what you meant by "rough edit" stage, but it's really not the correct phrase. I can't think of a better one, other than "the offline". Maybe just the creative part of the editing process.

Tivo? (1)

There are cute little hacks that allow you to display fun things like caller id and weather on your tivo. Why not hack up the scripts (tcl, I think) to display whatever it is you are looking for. Then you can just broadcast/record from the tivo's video out ports.

Disclaimer: I've never done this.

You want VJ Software. (1)

rogerbo (74443) | more than 9 years ago | (#10189283)

you want Vj software. Others have suggested VDMX, but also have a look at They have reviews of a ton of
other VJ tools. Most of them can superimpose text or any arbitary clip over a live feed.

I do this kind of thing all the time at my VJ gigs performing live with a Tibook.

VDMX will do text in real time, and let you save to the harddisk or send it back out through s-video, a firewire box, whatever.

however, Vidvox's new software, Grid2, is much more in line with the ideas the orignal question posed, even if the question was a bit off. So far, however, it won't do the text, but it does a ton of other stuff related to the concept I think the question was getting at.

I think a window's version is supposed to be coming out soon, but right now it's mac only.

Of course, if you really just want to take a video feed, add text, and go back out, VDMX will do that without a hitch, and look a hell of a lot better than old Character Generators (i love pixelated fonts!).

I use both on a regular basis for VJing and presentations at school.

Keep your eye on EvoCam and their web cam tool. It can do quite a bit of on the fly rendering and can do Alpha channels.Graphics and text are easy to configure If you are creating output for the web, this can't be beat

It's not a switcher, it's an editing/finishing rig. Nothing to do with live video.

have a look at max msp jitter, it is realtime if you want... dont know if thats what you are looking for.

Realtime Video Overlay? (1)

MacFury (659201) | more than 9 years ago | (#10209820)

I'm going to jump on this thread with a question that I've yet to answer.

Are there any programs, prefereably for free, that will allow you to overlay live video on previously recorded video?

Essentially I'm recording an actors movement on one side of the screen. I'll then capture that video on to the computer. I would then like to playback that captured video with a live video overlay. I'll then have the actor move accordingly as to not block his previous self.

I'm not looking for real time green screening or anything like that...just playing two videos on top of each other, one realtime the other previously captured. I'll do all the fancy compositing in after effects after I get good footage.

Sure, most of the software described in the survey I gave will do this

Under the VJ Bonnet ( Vid Software Round-Up) []

Most of those have trial version on their web site.
Max/MSP Jitter is a very powerfull environment but the learning curve is big.
Most of the VJ applications have a very simple interface to layer real-time video streams with video loops stored on your harddrive.
Some do support triggering the layers via MIDI, that can be handy if you are working with musicians or need to synchronize to external actions. There are ton's of MIDI device that can generate signals depending on movements, triggers, sound...
Depending on your machine, quality you need, numbers of video layers you want to play, you will need to compress the video in a codec that is well suited to those applications. Most of the time the QuickTime photo-jpeg is very nice regarding the quality and the load on the CPU.

Just get a chroma/blue-screen analog device, and use powerpoint on a mac with two monitors.

One monitor to show the powerpoint application, the other to show the slide output. Now make the background pure blue, and insert text. Split the output from the slide-show screen so you have a composite output, and a vga output. Take the composite output into an analog chroma-key device, and you're set.

Live video processing (and output), keying, delays, text gen, variable resolutions. Somewhat similar to Jitter, but much easier to learn, and a good bit less expensive.
