Tried the compiled version posted in this thread and it works.
1) When in video recording mode and not actively recording, pressing the menu button (not alt-menu) does not bring up the canon menu. Tried with normal allbest #51 and the canon menu does come up.
2) What is happening in terms of refocusing after zoom? The focus does appear to change, but it doesn't look like it's performing an auto-refocus, so it's not as focuses as it can be, especially if you change subjects. Would be nice for it to auto-refocus or refocus at half-press.
3) The default video settings are:
Video Mode: Bitrate
Video Bitrate: 1x
Video Quality: 84
This will cause video to look like it came from an atari 2600. Fix is to change Video Mode from Bitrate to Quality.
Also, it looks like with video support, CHDK will record video at its own quality/bitrate settings and ignore the canon settings.
I recorded a static scene for 30 seconds and got these results:
no chdk, 640 standard: ~60MB
no chdk, 640 LP: ~30MB
chdk, quality 84: 90MB
chdk, quality 55: 50MB
So it looks like I will need to do some trial and error tests to figure out the chdk quality settings to match canon's standard and LP, unless someone has done that already. I want to match canon's settings as close as possible since the available video time is based off of canon's values.
p.s.: someone made a build that allowed the chdk osd to be hidden during playback so that would be a nice feature to have.
