As you can see, I have been experimenting with posting video on my blog now that I have a HD Video Camera (JVC GZ-HD7U). I have been trying various encoding formats in Expression Encoder to get a good balance of bit-rate and quality. Here is my workflow:
- I shoot the video at 1080p
- I connect the camera via USB to my Lenovo T60p running Windows Vista and download the .tod files to my systems.
- I rename the .tod files to have .mpg extensions (because they are actually MPEG-2 encoded video files)
- I edit the video with Sony Vegas Movie Studio Platinum 8.0 and output .WMV files at 1280×720 4Mbps bit-rate
- I open the .WMV files in Expression Encoder to experiment with various bit-rates to get the quality that I want. If I crank up the bit-rate, I get buffering, If I lower the bit-rate, quality suffers. I finally came upon a combination that I liked and saved it as a profile (Silverlight Streaming 720p).
- 24 frames/second
- VC1 Variable-bit-rate (1,333 average, 2000 peak)
- 10 second buffer
- 96kbps audio
If you have any suggestions for better encoding combinations for HD-quality Silverlight video, I’d love to hear your feedback. I have attached the Expression encoding profile so you can try it out as well. To install it, just drop the attached .prx file into C:\Users\%username%\Documents\Expression\Expression Encoder\Profiles.
