Yesterday I was fiddling with the PowerShot A430, the second secondhand camera I got, and for some reason decided to look up how long it could record video for. Unlike other cameras I have used, such as the S45, which have a time limit of a couple of minutes this camera will keep recording until the output file reaches 1GB.
When set to 640×480 it says that it can fit 47 minutes on the 2GB card. To say it another way: 33 minutes per video. That’s enough to record my commute so before I left home this morning I mounted the camera to my bike. and they have just finished uploading to YouTube
The ride to work:
The ride home:
I only started using that route home a week ago and it is the shortest yet. Not to mention that there isn’t a single traffic light and I avoid a couple of dodgy bits caused by riding on the footpath up Blackburn Road.
Here it is in map form:
The file from the camera is 640×480 at 10 fps and around 800MB for each 20 minute ride. Converting to Xvid at average settings dropped that to around 140MB. To fit under YouTube’s 10 minute limit I sped it up 3x, which also makes it a bit more interesting. Also to make it easier to upload I reduced it to 352×288 to get a much smaller file. I also removed the audio as there was lots of wind and other noises.
While recording video worked well, it’s not an option for longer rides. For those I still want the camera to automatically take a full resolution photo at frequent intervals.
