OK, forgiven - but you have to do my gardening then...
I'll make a time-lapse while cutting your garden's grass
Depends from your needs & your definition of quality...50 or less may give some noticeable artefacts, but the video is still ok...
BTW - you know that you can adjust the settings on-the-fly ? --> CHDK video parameters
Instead of the "Video Quality" setting you could also test the "Video Bitrate", see the differences in CHDK wikia - Usage...
See also the discussion with some sample bitrates: Ewavr's VideoPlus - Discussion (some informations there may be outdated).
Wow that's interesting, i missed the on-the fly adjustable video bitrate feature!!
I just tried it, but i didn't understand how to see on the display the current bitrate and the modification that i make on the fly...
In the chdk menu i cannot find the "Show Remaining Videotime" described here
http://chdk.wikia.com/wiki/CHDK/MoreBest#Video_ParametersNo, only the quality setting can be controlled with CHDK.
Ok, thanks.
