I'd like to know approximately how many minutes of Video at 640x480 in a MPEG 4 format a 1 GB SD card can hold. Thanks
Hi g-paw
I'm no expert, but I think the actual amount you can fit on your card will depend on many things (besides the video resolution), including:
-Video Bitrate & Compression
-Audio Bitrate & Compression
-Actual MPEG4 Codec Version/Implementation
-Specific Program used to create the video
-Content of the Video (lots of moving images/detail, vs slow & bland images)
The most accurate way I suggest for you to work this out is to create a small amount of video (say, 1 or 2 minutes) of the type you plan to put on your SD card, see how big the resulting file is, then extrapolate from there to work out how many minutes 1 Gb will hold.
Some other people may have a rough idea of the amount you can fit, but this is my suggestion...
Hope this helps.
