![]() This increases the time it takes to edit and encode. The default prefs leave you with many hundred MB for even a few minutes of capture. There are also a number of tweaks you can make to the snapz pro prefs file that can leave you with lossless animation where you get about 1-2MB per minute. It makes a world of difference for rendering the SnapZ Pro capture! Get two 10K drives (or even 15K) and RAID 0 them for capture. If you don’t have the RAM then use the AppleRaid that you have available (in Disk Utility). I record in small segments (so as to not fill up the RAM disk which I usually set to 500MB - I have 3 Gig of RAM) then simply use QT Player Pro to piece things together. Esperance DV - 2.3.2 is a great way to go for this. If you have the RAM then a RAM disk is the ONLY way to go. SnapZ Pro is the least intrusive - although you do have to wait for encoding time, unlike iShowU.Īlso of note is the time it takes to encode a SnapZ Pro capture. If you’re recording something like Photoshop then you need as much horse power as possible. If you have multiple cores then you’re probably ok with iShowU. iShowU you will jump and spike many times to 90% and more. ![]() Snapz will typically hover around 10-15% CPU usage (depending on what it’s capturing). Run Activity Monitor while you shoot and you will see why SnapZ pro is better. If you are testing them both then shoot the same video with both packages. It is definitely better than iShow you - in my opinion. I’ve been making screencasts since SnapZ Pro was released. The audio part of your recording is actually larger than one would think (a 10 minute movie with 128 kbps audio uses 9 MB for the soundtrack alone) so be sure to use compression here.Ī last option is the Prepare for Internet Streaming which you should set to Fast Start - this is what allows the movie to start playing before it has been fully downloaded. I use QuickTime Pro ($29.99 from the Apple store) to export it using the H.264 codec, frame rate set to 10 and quality set to high.įor the audio part I use 64 kbps AAC. Be sure to also enable audio when saving. Basically I want loss-less, but I think this option is what gets the closest. When done recording I save the file with the Animation codec, millions of colors, and highest quality. It isn’t easy to do them as one-take though, and sometimes I have to start over or cut them short - if I did more of them, I’d invest the time to learn a video editing program so that I could edit the videos after having recorded them, perhaps even record the soundtrack after having recorded the actual video and also skip boring parts in editing.īut for now, I think the time it takes me to get them right as a one-take is still shorter than having to stitch together multiple recordings and/or add a soundtrack in editing. This gives me a feel for where trouble will arise and which things I need to prepare better or be sure to have memorized. Normally I first go through the stuff I want to show without recording it, just talking to myself. The resolution for this is 800×600 so that I can record the full screen and get a decently sized movie without panning around or having to scale the result (and get a blurry movie). I have created a user account specifically for recording screencasts. So definitely check if this setting has the same effect on your system! Setup I found that if I have Auto mic input gain enabled in Snapz Pro X (the default) then it will set my Input Volume to 50% when I start recording. One thing to check is the Input Volume for your device in System Preferences → Sound. If anyone has headset recommendations, please add them to the comments. It works great, but I would prefer a headset since I occasionally move around while recording and this can change the volume of my voice. Hardwareįor the audio I am using a Logitech (USB) desktop microphone. ![]() ![]() It is an Apple-style keystroke visualizer. If you do a lot of key presses in your screencast then you may find Ke圜astr useful. It’s a little pricey ($69) but I have tried several of the alternatives, and none of them gave me a result as good as Snapz Pro X. I am often asked about details related to recording screencasts, so here goes. Next post: TextMate 1.5.6 Recording Screencasts ![]() Previous post: Dialogs in TextMate (Part 2) ![]()
