View Full Version here: : I give up...

Right about now I am in the worst mood possible. :mad2:

Here's what happened....

Last night the clouds cleared and left a night that any amateur astronomer would die for. No wind, No cloud, nice weather and good seeing! I had left the scope out to cool for a few hours and it all looked like it was going to be an amazing night. Everything was now set up and I was ready to start imaging. :)

To start off I captured around 6 AVI's of Saturn. When I was satisfied, I decided to see if I could capture one of my favourite DSO M104. This bit was all a bit of mucking around but what do you know... It was there on the screen the first time! :eyepop:

In between while the scope was moving I somehow changed the settings on the capture software so the camera was now compressing the AVI's. :mad2::mad2: I had absolutely no idea of this so I was happily shooting away at M104. I shot 4 AVI's of M104 and I now decided to go back and shoot a few more of Saturn.

By the time now the seeing had improved and I could easily see the Cassini Division and banding. I was really excited and captured a few more AVI's.

Then when I go through all of last nights work and the best of them were the last batch of AVI's I took (the compressed ones). My good friend Registax refused to open the AVI's. :mad2::mad2::mad2: So I was left with rubbish.

I give up... :bashcomp: :sad:

What would astronomy be without of all of this? :confuse2:

It has me puzzled. :rolleyes:

Groan! But I got lots of hits on "uncompress AVI" in Google??

Registax has trouble when an avi is more than 1gb in size, give or take. If your avi's are over 1gb you need to strip the frames down to individual bitmaps using something like Virtualdub. Then you can load all the frames into Registax by selecting them all and dragging and dropping. Iceman wrote a great article (http://www.iceinspace.com.au/index.php?id=63,306,0,0,1,0) on planetary imaging that explains it all.

Just slap me and tell me to shut it if you already knew all that.:D

cheers

Hi Mark,

When I tried to open the AVI a message came and said unable to start AVI compression. I'm guessing Registax doen't like the the codec I was using.

BTW I've had AVI's the size of 4gb and Registax opened them with any problems. I have also opened a max of 10,000 frames aswell. :)

Forgive me if this is not of any help, I am very new to Astronomy but do happen to know a thing about computers, try this site: http://rsb.info.nih.gov/ij/plugins/avi-reader.html, if that does not work you could also try: http://www.giveawayoftheday.com/freeware/avi/decompressor, let me know how you go with that,

Cheers

Thanks for the links Nick, I'll see what I can do.

Matty,

This process will fix it.

For me it was with the DBK, so once you get it in to Registax, you'll have to work it out on your own (ie do your normal thing), but in a nutshell, it will convert the AVI from it's native format (assuming when you double-click on it you can view the video in windows)

It's slower than doing it on the raw file, but easier than trying to get it converted to something else.

hehe we all get frustrated at times - just remember nothing easy is worth doing :whistle:

I totally agree with you Mark. I need to remember that.

OK back to the AVI's. I tried to salvage the compressed AVI's but from the quality of each AVI. I am sorry to say (I'm not really sorry :rolleyes:) that it didn't work out so they are currently in the recycle bin on the lappy.

This springs to mind "Fool me once shame you, fool me twice shame on me!" If this ever happens again I might need to stick a post it on my head to remind myself. :screwy:

Thanks for your help.
