I prefer quality over file size, so I like to switch the Video Paramaters to record in Constant Bitrate Mode and I'll use the highest possible setting of 3 X when using my Canon SD 400. The resulting video is superb and it functions correctly; The way I confirm this is opening the video in Quicktime and looking at the video properties window. It will show that the Data Rate is 30 -50 Mbit/s.
Sadly, my Canon SD 400 will need replacing soon due to age. I am looking for a good replacement that can record in Constant Bitrate successfully. I emphasize "successfully" because I recently purchased the Canon SD 1100 (IXUS 80) thinking that since it's on the list of completed builds, all features of CHDK would work, including Video-Constant Bitrate Mode. The CHDK build for the 1100 allows me to select the Constant Bitrate Mode and select a 3 X level, but when I check the video in Quicktime, the highest Data Rate would never past 15 Mbit/s. I am using the exact same type of SD card for both so I don't think SD card speed would be an issue. Please, let me know of other cameras/builds that can use the Video - Constant Bitrate Mode successfully, by verifying the Data Rate on your computer.
Thanks in advance!
