In recent versions of FFmpeg, use the crop filter: ffmpeg -i in.mp4 -filter:v "crop=out_w:out_h:x:y" out.mp4 Where the options are as follows: out_w is the width of the output rectangle out_h is the height of the output rectangle x and y specify the top left corner of the output rectangle So, for example, to crop a 640×480 window, starting from ...

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 ...

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.

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 ...

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.

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.

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 ...

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 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.

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.

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.

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 ...

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.

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 ...

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 ...

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

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 ...

Directing actors is a technical part of film making. It's not easy, and if your actors don't give good performances, chances are you won't have a good film. People can usually forgive bland cinematography and clunky editing – but if they don't believe the characters then you're going to have no chance in engaging the audience. I go to a film school myself ...

After Effects has a frame blending mode called "Pixel Motion," which will attempt to match features in two temporally adjacent frames and smoothly blend between them. This video shows it in action, where it is used to generate filler frames for video footage that was slowed down 10x. As you can see, the results are mixed. There is no magic bullet for ...

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!

I think the traditional knowledge is that if you want to be an editor, then you should know how to drive all 3 of the major programs (Avid, Final Cut Studio, and Premiere), and maybe some of the less mainstream broadcast editing and finishing systems (e.g. Smoke). You should probably know a handful of specialized audio programs too. Lucky for you, the ...

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.

What format is your long video? The seeking performance problem may not be in Kdenlive but in your movie. If you aren't yet, you should consider using a container format that has index tables. Now regarding extracting a clip from a movie, I believe you can do that with ffmpeg, specifying a codec named "copy" and setting a start position and a duration (in ...

Drawing out a viewfinder should not be a big deal. You can do this quicker than searching for one. Do it in photoshop or another decent app. Draw the lines with anti-aliasing on a transparent layer and export it as a PNG with transparency. You may want to set the layer compositing mode in FCP to be something other than the default, play around a bit. ...

If you have a 8 core CPU I'd bet it is a fast one too, so that shouldn't be a problem. 16 GB is more than enough for HD, and DDR3 should ensure the speed. The GPU shouldn't have much to say as long as it's not crap. If you have 6 slow harddrives, it would be a bottleneck. You should have at least 7200 rpm disks!

Drives are definitely the answer. My miniDV setup worked fine with 5400rpm, but HD playback looked like internet video from 2004. Upgraded to 7200rpm internal SATA drives, and ~most~ of the time, I've got good results. While I've never done any work with SSDs, I suspect those would be the ideal circumstance. For external drives, I've used 5400rpm USB2.0 ...
