Lessons learned from video creation

Room and equipment

  • we need a better video room, 301 is not suited (white walls)
  • done - canon we also need a 16:9 camera with min 640 x 350 resolution
  • camera with external microphone?

Attach:VideoSetupAll.jpg Δ

Set-tup

  • tripod for the camera,
  • best with: 2 cameras, 1 for content, 1 for overall picure
  • text on Laptop "underneath the camera"
  • sitting makes presentations more relaxed
  • extra light: see the picture which makes presenter more visible (250 W lamp)

Recording

  • "Wellcome" - look into camera (always, never look at the others)
  • subdivide into scenes, with clear "start & stop"
  • if showing something, give it time to let the video stabilize

Converting from Canon .mts format

  • using: MPEG Streamclip (on Windows)
  • using Pavtube MTS converter, MTS to MKV for Mac OSX (Oct2011)
  • 16.5.2011 - import of MTS does not work any longer (Josef)
  • Attach Camera to MAC and import from iMovie (camera import)
  • Use iMovie v09, and upload directly to YouTube (or export Quick Time).
    • Highest Resolution 1280x720, AAC 48000 bits/s audio
    • 7 min generate 350 MByte
  • publish directly to YouTube

alternative 1:

  • install Canon software - no experience in using it

alternative 2:

  • Free Video converter for PC
  • MPEG4 conversion with 720x406 pixel, aspect 16:9, 25 fps at 1152 kbit/s (not readable for MAC)

Converting and upload

Adding images

  • I had the "Initial Photo Placement" set to "Fit in Frame" which totally borked the transparent PNG. If I changed it to "Ken Burns" and then after imported I set it to "Fit in Frame" or "Crop" it would also bork the PNG and display it as a solid black box.

iMovie creation (on MAC)

  • Create Movie with iMovie
    • open issues: Logo in video stream,
    • tips: import captions, then adjust the length of the caption

Our example

  • full page logos for usage in iMovie in Graffle
  • logo with transparent background created in keynote with "alpha"
  • copy into OmniGraffle (into the invisible frame)
  • Export 100% png with transparent
  • slightly different way: Good intro on how to add images and logos to iMovie

Export to Quick Time Movie - HD quality

  • MPEG-4, Best Quality
  • Size 1280-720 HD - preserve aspect ratio
  • 7 min gives 280 MByte, 35 min to create

Export to Quick Time Movie - SD quality

  • MPEG-4, Best quality
  • Size 786 x 580 SD, automatic stream
  • needs about 14 min to create, 486 MByte (??)

Errors/Unsufficient results

  • why does variable bit-rate cause such a dramatic size effect (doubling despite lower resolution)?
  • export to quick time looses auto-sync

I have a 15" MacBook Pro -unibody. Get a 15", max out the RAM & HD and then buy a monitor like the 24" LED from Apple. (Just don't epexct to do serious color balancing for printing on it). The larger display, combined with Spaces and being able to use both the laptop and external monitor gives you a lot of flexibility. If you're on the road much more than stationary, then go for the 17" to give yourself enough room, and still get the external monitor. I just found the 17" to be really awkward for practical travel and backpack stowage.The biggest jump in productivity I ever got was getting the largest display monitor available at the time.

I agree with most everyone here. the 17" is just not prcatiacl for travel. I personally use an almost 2 year old 15" macbook pro for lots of web design (using Coda and CSSEdit, mainly, i think DreamWeaver's interface probably takes up more screen real estate??) and editing videos with Final Cut Pro. I upgraded the RAM myself to just 2 gigs, which is a little slow. 4 gigs of RAM is plenty for what you want to do. I also swapped out my 120gb hard drive for a 320gb. It was a bit of a challenge, but not overly difficult. i'm pretty sure it voided my warranty, though, so if that's important, you might want to get a decent sized hard drive straight from apple (then in a year or so, when SSD drives come down more in price, put in one of those). I also use a 20" cinema display with a "real" mouse and keyboard when I'm at home, and it works out well. Apple's monitors are too expensive, though. go with a Dell or Samsung monitor.Hope this helps. It seems to be a theme here anyway

> I like to blog. Mobility is important.MBP17 is the most molibe 17"er out there.> I want to do more video editing, especially with iMovie (although I need some schooling here ).The 15" native res is 1440 while the 17" native res is 1920. If you have good peepers, the 17 is king here. not just for movie editing but for everything you do. more lines of code per page in your editor, more columns in tweetdeck, etc.> Solid State or ATA? At this point, I m not sure. Obviously one is more expensive and I d be willing to go with the former if itsize over speed if you have children and a hi def camera. but, balance it out too. id go with the 320gb 7200rpm HD.> Do I really need 8gigs? Or is that just bogus dunno.> Is the speed increases worth the extra bucks?as a rule i always go for the top CPU. but i keep my computers 4+ years.> The 17 doesn t have a removal battery, right? What happens when that thing gives out?not an issue for techies. step by step how-tos with pics will be easily available if yours gives out. this would be a concern for my mom but not a tech guy.Go with a 17" because of the screen real estate (resolution, not physical size) alone and the fact that if you are settled on a MBP anyway the MBP17 is the most portable 17 ever made.The only caveat is if you have a nice 24"+ LCD at home/work. If you have a nicer display that you will be plugged into >50% of the time go with a 15".peace|dewde

Very good editing; sometime did not zoom at right time. When focusing the contents, only TV may appear in full screen (withour any faces) with pointing fingers or some pointing marks.
