Anything substantial like 25% smaller ?

nowhere near, about 17-18 kB for 3.4.6 -> 4.5.1
                    about  14.5 kB for  3.4.6 -> 4.4.0

Savings tend to be a fixed amount of kB, so % will vary, I'd say maybe  6 - 7 %,
at the expense of at least double the compile time.

hth,

wim

Hello,

I'm trying to do my SD card self bootable, but when I go to the CHDK menu and I press the option "make sd card bootable..." nothing happens.

Anyway, after pressing the option, as I didn't know if it worked, I extracted the card, locked it and try to power on the camera with it and gives me a card error.

What am I doing wrong?

Mi SD card es a SDHC of 8gb and is in FAT 32.

Hello & welcome, DFA !

I'm trying to do my SD card self bootable, but when I go to the CHDK menu and I press the option "make sd card bootable..." nothing happens.
...
Mi SD card es a SDHC of 8gb and is in FAT 32.

The CHDK autostart feature (with a CHDK-bootable card) only work with FAT12 / FAT16 partitions.

You may use your 8GB part with the default single partition and start CHDK manually,
if you want to use the CHDK autostart method you have to partition your card...

Thanks fe50.

I read all this, and I see that I have to make 2 partitions in my card, one small with FAT16, and other bigger with FAT32.

But after reading that windows has problems to read 2 partitions in a SD Card (is that true?) and I have to swap partitions every time I want to transfer images to my PC...

I'm thinking in:

1. buying a 4GB card to format in FAT16 and work with it when I want CHDK.
It will work in this way in my IXUS 100? (Because the default card format of this camera is FAT32)
Is there any problem in working in FAT16 with the hole 4gb card? in speed or something?


2. Or make the two partitions, one small in FAT16 and the bigger in FAT32.
In this way, Do I have to swap the partitions to read the card from a card reader or can I use the camera plugged to transfer the images, right?

What people do?

Yes, but you have to format the card with a card reader to use FAT16 (the camera will format cards > 2GB with FAT32 by default).

No, no problems/issues.

You can transfer the images as usual with the USB cable (note: you may need to disable the CHDK remote feature in the CHDK Remote Parameter" menu),
you can also swap the partitions from the CHDK menu (http://chdk.wikia.com/wiki/CHDK_User_Manual#Swap_partitions)...

A question about CHDK on video.
1. The quality can be increased to a 100. Has anyone seen an increase in bitrate due to this, or shot a resolution chart to confirm that it works ?
2. Is there a way to force aperture priority mode in video - so we can set the shutter to 1/60 while shooting, or even use fully manual controls in video ?
3. Any chance that we can get other framerates i.e. 25P, 50P, 60P ?

There is a reference in this forum to someone who did tests.
Conclusion was they made no difference, just increased file size.
JOhn Hart on the Yahoo SDM Group reported something similar.

You cannot set arbitrary framerates.

Most important for you, 57 cameras (or even two) cannot be accurately synchronised.
