More on why Flash is bad for video playback

Cringely has a column on the iPad, and he has some information from an "informed friend" about Flash performance:
I did a quickie test with the new YouTube HTML5 beta. On a site that embedded a video (so Flash was used), my browser CPU utilization was 22%, and the Adobe Flash plug-in CPU utilization was 55%. [...]

After the video played, I watched the same video again directly on the YouTube site in HTML5. Adobe Flash plug-in CPU utilization was 4% (what it consumes just sitting on its hiney), and the browser CPU utilization was 17%.

77% vs 21%. that’s why Apple hates Adobe.
That's basically what Craig Seeman of Third Planet Video said at a recent BOSFCPUG meeting.

And to be sure, I don't hate Flash either, and I hope they do put it on the iPad so we can use it for interactive games etc., but unless Adobe can fix the performance issues, I really think Flash is the wrong thing for video playback.

Sony GV-D200 review

Image
Sony GV-D200 I've been using a Sony GV-D200 deck to transfer old Video8 and Hi8 tapes. Some of these tapes are over twenty years old, and no longer having a Hi8 camcorder that worked I was concerned that if I didn't do something about transferring them to a more modern format soon, I might never be able to. While Sony no longer make camcorders that use these tapes - that I know of - Sony does still sell the GV-D200 deck (or Video Walkman, as it's sometimes labelled.) They also offer the GV-D800, which is almost identical but adds a small LCD screen for about $120 more. I didn't think I'd need a screen since I was using this to capture to the computer, but you will need an external monitor when you first set it up. Physically, the device is small. At 5 7/8" wide, 5 3/8" deep and 2" high, it's the smallest video deck I've encountered. I used to have a Video8 deck that I thought was small; and it was twice as deep and twice as high. The t...

Response: Which iPhone to Get?

Image
In response to my iPhone musings, I got the following reader email which actually sums up a lot of my second and third thoughts too: You might have a point about the fancier camera, but otherwise I would buy the smaller model. Its screen is about the same size as that of my Nexus 4, and I don't feel at all like it limits me with a too-small screen. But I do sometimes stretch to get my thumb the reach to the other corner of the screen. It is plenty big for a phone. A phone is a pocket thing. (Well, in my case it lives an ancient REI soft sunglasses case that I have on my belt.) Ubiquitous, handy, convenient, almost always with me. Small is crucial for all of that. Certainly a large screen is cool, but you need a place to put it: don't break a fundamental feature of a pocket phone by getting too big. That is what your small tablet is for. I have my phone with me almost always. I have my Nexus 7 tablet with me nearly as much. The bigger screen is great, yet it fits in some...

Should you buy the Sony NEX-FS100 Kit Lens?

Image
The Sony NEX-FS100 is available in two configurations: B & H : NEX-FS100U Camcorder only $4,999 B & H : NEX-FS100U (with 18-200mm lens) $5,599 But what does that extra $600 get you? It get's you this: Sony 18-200mm f/3.5-6.3 Zoom Lens for NEX Camera This lens is also available separately for $799.99, so at $200 off you'd think everyone would be jumping on it. But not so fast... In his article about switching from the Canon 5D Mark II to the Sony NEX-FS100 , Paul Antico  at Need Creative says of the kit lens: 7) Its 18-200 F3.6-6.3 kit lens absolutely sucks and should be avoided (thankfully, you can order it without one) [ 1 ] But is it that bad? At B & H 's site, 43 reviews give it an average of 4.6 out of 5 stars. That's not a bad rating, though many of these people are using it for stills, and the most common complaint noted is how large and heavy it is. Of course this feeling of size would be exacerbated when you put it on a tiny camera ...
