When is a 2 min AVI in fact longer than 2 mins?

[John K]

With Jupiter imaging back into the swing of things, one of the things I have noticed is that my avi's have been a lot longer than expected in actual time to record.

This means that a 130 second AVI is in fact taking 2min 10 seconds, a 150 second AVI takes 2 min 30 seconds and a 165 second AVI takes 2 min 45 seconds. This is at 10 fps. With Jupiter spinning so fast the recommendation is in fact to limit imaging to 2 mins.

Is the fact that I am recording at the full Y2KH?? (whatever it's called) compression causing this? Also, in Registax, I find that I get limited to 1650 or thereabouts in these high res frames even after AVI Raw ras done it's RGB thing.

Thoughts appreciated.

p.s. hate to admit it but I still use AMCAP to capture all my AVI's, seems to work better on my Laptop that K3CCD tools for some reason in terms of the live stream I get when focusing/capturing whereas K3CCD tools gives a very fragmented streaming live view.

Possibly I misunderstand the question but 130secs is 2min 10sec is it not ?

ok, I am a little confused.

130 seconds is actually 2 x 60 secs = 120 + 10 secs = 2 mins 10 seconds??? which is spot on.

This morning, i stuffed a red channel, so I actually ended up recording 35 blue + 12 changeover + 35 seconds green + 12 seconds changeover + 35 bad red + another 35 seconds but this time good red = 164 seconds.

for my scale, i could not see any rotation.

I know bird is pushing 150 seconds and he is noticing rotation but for his bigger image scale.

I really like qfocus for capturing, it allows previewing and capturing of raw mode

Thanks Lert and DP,

We'll put part of my thread into the "most stupid question of the day" courtecy of my early morning Jupiter rises. For some reason always kept thinking it was 1.3mins, 1.5 and 1.6 minutes.

DP - ta, I'll download QFocus and have a play.
