FFmpeg with a lossless codec is one solution. I recall a comparison of different codecs which concluded that Apple Animation (known to ffmpeg as qtrle) gave the best quality for screen-recording. ffmpeg -f x11grab -r 25 -s 1024x768 -i :0.0 -c:v qtrle output.mov Stop it by opening its terminal while it is running and pressing q. Obviously change the ...

Personally I use Camtasia Studio and SnagIt. TechSmith, the vendor, has created their own codec for their software which IMO works excellent. You will probably find Camtasia a bit stiff when it comes to the price compared to your budget, but I mentioned SnagIt for this reason although it's primarily to capture screenshots it do have built-in video recording ...

There are a lot of screen recording software, for example: CamStudio (free) Screenpresso (free/paid versions) Movavi Screen Capture Studio ($49.95) Camtasia Studio ($299.00)

If you're OK with the command-line, you could use ffmpeg to record your desktop and then use the tee psuedo-muxer to record copies to multiple locations. I haven't used this to record to separate hard-drives, but I'm not aware of any underlying issues that would prevent it. A simple (Linux) example would be: ffmpeg -f x11grab -r 25 -s 1024x768 -i :0.0 -f ...

You can't do much about it. Movie Maker can only export in WMV format - and WMV is created for small video sizes (at the cost of quality). You will need another software package to export in other formats than WMV. Check out Pinnacle products for alternative - they target amateur producers.

As long as the video isn't copy protected, you will want to use a stream ripper instead of trying to do a screen capture of your monitor. Any number of software products are able to directly transfer a video that is in the Flash streaming video format as long as it isn't copy protected. A quick search for "flash video ripper" and your operating system ...

Alternatively, pipe your screen output to a second computer to record, using a device like a Blackmagic Intensity. It supports capturing to a totally uncompressed format (make sure you have an SSD or a RAID setup to record as the bitrate is very high). So the computer you're doing the work on should have dual monitor output - mirror the display so one ...

The problem with compression is that it is a double edged sword. It can reduce the space required to store video, however it also takes processing time to perform the compression. When you are running a game, however, the CPU and GPU are already busy keeping the game running smoothly. In order to shrink the file size, you must either reduce the quality or ...

Have you tried WebVTT for marking up the subtitles? http://www.w3.org/community/texttracks/2012/08/23/webvtt-support-in-browsers/ http://ie.microsoft.com/testdrive/Graphics/CaptionMaker/ is a surprisingly good tool for making captions. You could also cheat a bit and use Youtube's pretty good voice recognition to perhaps save time transcribing.

Ordinarily, I'd create an Adobe AIR or AIR-for-iOS app to solve this problem. You'd just sychronize your captions to cue points in the video and make 'em visible or invisible with a programmed-in button. You could easily have multiple languages in this way. Are iTunes podcasts just flat-out mp4 movies?

Capturing the video frames in XWD format then converting to PNG yields results that are almost pixel perfect when encoded with ffmpeg. Install xvidcap: mkdir -p $HOME/dev cd $HOME/dev svn checkout svn://svn.code.sf.net/p/xvidcap/code/trunk xvidcap-code cd xvidcap* ./autogen.sh LIBS="-ldl -lX11 -lXext" ./configure --prefix=/usr/local make && sudo ...

You have two options, one, install software on the presenter's system that can encode and send a video feed to another system. This is in-effect going to be a screen casting application, even if the feed is only forwarded to another system to be packaged. The other option is to actually capture the raw output from the presenter's system through a frame ...

I know you looked at ScreenFlow. Were you looking at the latest version--ScreenFlow 4? It does have some vectorial shapes (they're called Annotations): Line (arrow) Line Square (filled) Square Circle Now, that doesn't get you speech bubbles and other abstract shapes. For those, you can use a text box with an image fill--unfortunately, you've got to ...

Here's a non-command-line option. Try Collaaj (http://collaaj.com). Works on PC & Mac. It doesn't work on Ubuntu, but since you mentioned you have OSX, this should work just fine. I think it should do what you asked for and more. Such as region selection, selecting inputs etc.., and it also lets you upload and maintain your recordings on collaaj.com for ...

Add your video to your timeline. Then you play the video from the beginning. Now you are going to insert a marker every time you want a new clip to be inserted. If you have CS6, the shortcut is M, otherwise it's * on the numpad. When you've added all the markers, you should delete the video track (since you only want the audio. If you want to render the ...

You can do this with Processing. You would have to write a processing sketch to step through the movie frame-by-frame, and calculate how different each was from the previous frame. When the difference is above a certain threshold, save the whole frame as an image file. Here is a forum post about something very similar. Other than processing, you may ...

Generally speaking shooting in 1080p and scaling it down to 720p is not a problem with cameras as I do this all the time and it looks just fine. When I do this I may also be mixing 1080p and 720p raw images, and I always scale to the lowest resolution. When I render a 1080p I will generally render a 720p version as an answer print to view before committing ...

He uses Camtasia Pro ($200) a Wacom tablet and (at least on the earliest videos) MS Paint. And a head mic. http://www.teachthought.com/technology/how-to-screencast-like-the-khan-academy/ On a mac, a similar piece of screen capture software would be Screenflow, although Khan works on a Windows machine: http://www.telestream.net/screenflow/

In camtasia, if you choose a certain location that it will store it in your used places. Then you can access it easily through the dropdown list. Here is an image: It isn't possible to change the default output folder though....
