VLMC is a non-linear multitrack editor. It's based on VLC and inherits a pretty vast format compatibility from that. The UI is a little rough, but it gets the job done. Lightworks is a more recent project and seems polished. It's rooted in broadcast editing, so a large number of familiar codecs are unsupported. It supports Matrox codecs, which you have to ...

Kdenlive is rapidly becoming the most advanced Open Source video editor for Linux. As a Windows user, you can download a live CD of Kdenlive. Burn it to a CD, and then it will boot up into a Linux system for you. Or, you could install Virtual Box on Windows (again, free software) and then install the live CD to that. This would allow you to simultaneously ...

You might want to see Wikipedia's Comparison of video editors and list of video editing software. From my personal experience I recommend Kdenlive over any others. It has good support for a wide range of non-linear video editing functions. If you are the real geek, you may want to try out Cinelera.

I believe the only answer to that is to take at least a 24hr break. Move onto another project or start something new. The number of times I have come back to something after a decent break and can all of a sudden see what needs to be done is shocking. I don't believe their is a quick fix to this issue.

You can do a simple image overlay using the following syntax: ffmpeg -i input.mp4 -i image.png \ -filter_complex "[0:v][1:v] overlay=25:25:enable='between(t,0,20)'" \ -pix_fmt yuv420p -c:a copy \ output.mp4 overlay=25:25 means we want to position the image 25px to the left and 25px down, originating from the top left corner. enable='between(t,0,20)' ...

There is an Linux/Gnome based video editor called PiTiVi which is working close with the GStreamer multimedia framework which is used by most Linux distributions. The PiTiVi project has been slow moving because of their development philosophy which is "upstream first". Challenges they encounter in GStreamer means that they work with GStreamer to solve the ...

I personally run Cinelerra CV and it's "mochup" Cinecutie on my Linux boxes. Cinelerra (and it's relatives) can do some very sophisticated editing work, but they aren't the easiest to use. Luckily, there are lots of video tutorials out there to help you.

PBS is made up of 354 different broadcasters and carry content from many different studios, it is highly unlikely that they all use one product and chances are good they use a product other than Final Cut or Premiere. Avid makes several very popular products and the software that drives actual broadcast studios isn't the same kind of software used by ...

If you want to Preview Audio you need to use RAM Preview... Press Numpad 0 on the number pad (shortcut key for Ram Preview), then you can hear the audio. Press Numpad 0 on the Numberpad.

First off, if you have audio with your video (that you want to replace with your high-quality audio recording), then step #1 is to nudge the Zoom audio track to line up the impulse of the clap with the corresponding impulse of the scratch audio from the video file. To do that, you need to change the Timecode Display Format to Audio Samples. Once you do ...

If you're on Linux, consider Cinelerra: the most powerful video editor for Linux, Openshot: simple, powerful, and free video editor for Linux, or Kdenlive (also available for FreeBSD and Mac OSX): Free and open source video editor for GUN/Linux and FreeBSD Openshot and Kdenlive can be installed via apt-get install, however Cinelerra requires a little more ...

Have you rendered the work area? Unrendered clips can lead to lag in the playback. If you have rendered your clips the bar above your clips in the timeline should light up green instead of red or yellow (see picture below). If the bar isn't green, go to Sequence->Render Entire Work Area. Done!

For Linux people: Kino It is a non-linear DV editor. It has many features including capture, editing, FX, and export to other formats. I've used it for several years without issue.

I think pretty much every editing program would allow you to zoom, pan and insert text. Inserting another video into the main video is a little more complex and the only program I know for sure that does it is After Effects. But I'm sure there are others that will. I would suggest using Premiere because it's a very powerful program. Even though I've never ...

I recommend the Creative Cow web site, specifically, http://forums.creativecow.net/adobeaftereffects. This will serve your need for getting help on AE, but this is not a site for posting to find some one to do the work for you. Hope this helps.

After Effects is not designed as an editing platform. Audio preview only works when you do a RAM Preview and pre-render all the frames for the content you are previewing. You never get Audio with the real-time preview. The intent behind RAM Preview is that it lets you check the final quality of the render prior to writing it to disk, but it isn't really ...

Letter box if you have bars on the top and bottom. Pillar box if you have them on the sides. Stretch (or possibly anamorphic, depending on what the intended playback aspect ratio is) if you are full screening it by stretching it out to fill the space. Cropped if you are making it full screen by cutting off the edges.

Do you realize people go through years of academical studies or expensive courses at private universities to learn all that? It's certainly not something you're going to master by watching a few Youtube videos ... If you want to seriously get into film making, I would suggest you take a course. Not necessarily a full blown film studies degree, but you could ...

From your description of the audio, it is going to be hard to fix, as white noise tends to cover a very broad frequency spectrum and so is hard to get rid of without losing what you want to keep. A decent starting point for you would be to use a freeware audio editing program like Audacity. Here is a noise removal tutorial using Audacity. You can also use ...

If you're not impressed with X then I'd suggest going back to version 7. Learning your way around a new program will be a pain in the arse. I'm not sure how professionally you work but if you can be bothered, Avid is a great program once you get to know it. Otherwise, man, I'd probably just get used to FCPX.

In my experience both Premiere and FCP will do pretty much the same thing. They have similar lay outs and, I would say, are as easy to use as each other. I first used Premiere when I had a PC but moved to FCP when I went to university and got a mac. I find it a lot easier to edit with FCP and the transition to other programs are very simple and effective ...

One solution to the jerkiness of stop-motion animation was developed for some Star Wars sequences, termed "Go Motion". Basically the idea is that you leave the shutter open a little longer than necessary, and move the objects a bit, to create some motion blur.

Found it! You can press the "J" key to play in reverse. Each time you hit the "J" it will jump a full speed up to x4. If you want to jump by speeds of .25x, hold the "K" button and hit "J". While it is play backwards, hitting the spacebar will jump you back to where you started playing, and hitting "K" will stop you where you are. To adjust playback speeds ...

So after 8 hours of research, trial and error, I found a successful workflow for .mov footage from my Canon EOS Rebel T3i. The first part is that you can't import .mov "Apple / H264" files with Lightworks without purchasing the "Pro" version. The pro version costs $60 per year (which is actually a good price for what you get). So I bought that and was ...

It's referred to as a jump cut. I would guess that perhaps the Apple ads that used it might have made it popular again, but that's just a guess. The idea behind it is to visually show a change in direction of thought since typically it matches up with the start of another phrase. It jumps the viewer forward in time and makes them aware of a subtle change ...

They call this the rolling shutter effect. Also known as the jello or wobble effect and is caused by the side to side motion of cameras that have the CMOS sensor. The rolling shutter effect can be caused by: fast moving objects, moving or panning the camera quickly, or camera vibrations. Why does this happen? The CMOS sensor on the camera reads ...

Yes, this is possible using ffmpeg and the mkv container. An example command sequence would be: ffmpeg -i input1 -i input2 -c copy -map 0 -map 1 output.mkv source Breaking down the command: -i input1 This selects the first input file. Could be something like my video_track1.mov. -i input2 Here you can specify the second input file. You can add another ...

Storyboard first, then shoot, then edit. A storyboard is a tool for organizing your thoughts before you even pick up a camera. It's like a script, and usually follows from a script, but gives you a better idea of where to place and move the camera. This is called "shot blocking". The shotgun method of gathering footage with the hope of being able to ...

I've used AudioMicro.com and like a lot of their music. I hear good things about incompetech.com. You can also just Google "royalty-free music sites" and you'll find several, each with different terms and prices.
