IISAC11 smooth timelapse part A

Hi Guys

A sunset time lapse which turned out pretty smooth I think.

Taken with a 5D Mk2, 24mm 1.4fL lens at 10 sec exposures 3200ISO and 30 fps, a frame rate which was a luxury and worth the bother.

No processing whatsoever, which is a nice change. Thanks Phil Hart for advance technical advice on every aspect of the capture (lens, ISO, exposure etc).

The 24mm 1.4L lens is a timelapse wonder, way better than everything else ive tried.

Movement via my Timelapse Machine on an EQ3 mount.

Oh Fred... I get massive artifacts! Anyone else have that problem?

It snaps back to nice sharp video about the 9s and 18s marks but deteriorates through square blocky over sized pixels to a very arty oil painting look... but I realise that, unfortunately, that's not what you're trying to achieve.

Great choice in music... the glimpses of good video I get, makes me want to see it all properly. What I can see looks awesome!

Al.

I tried letting it cache a while... no difference. I checked a couple of your other timelapses and they were fine (very good actually). Hmmm, I'm running a reasonably up-spec puter these days too...

I had that problem with some of Phil's videos on smugmug.

Not sure if he ever sorted it out?

In fact I have the same problem with yours.

Check with Phil - see if he figured out the problem. Cause I can't watch it

Played just fine on my iPad, lovely timelapse, I've never ventured past 800 ISO on my 5dII, might give 3200 a try based on your experience.

Great work Fred No artefacting whatsoever on my iMac. Smooth-as.

Geez, the F/1.4 really did give you what I thought it would, in comparison to those I used. One is now on my wish-list.

I've uploaded mine to Vimeo as well as a comparison. http://vimeo.com/31367809

Well, I like it Chris, again, the overall production makes it sort of natural and organic (with the sound track). Dont know if the vimeo res is that flash tho, theres some nasty artifacts there, and you could process in PS with a custom action to fix the exposure/noise right up.

Still no good. Full of blotchiness.

It's something to do with smugmug and certain computers/browser versions. Upload it to vimeo, and then speak to Phil to see if he figured out the smugmug problem.

Attached is an example of the blotchiness. At some moments it's clear and looks great, but most of the video is full of these massive blocks.

Chris I'm getting some artefacts on yours too, but not in the same way. Most of yours looks good, but in some parts the jpeg compression seems to have produced artefacts, see attached.

re time lapse

Just had to come back here and watch this again-its just magical,and the music that goes with it suits very well.A very masterful creation,the clouds go well with it.

I cannot believe how much detail is seen in the LMC!,best of all-no PP! just goes to show what an amazing machine the 5D2 is,and what a wonderful piece of glass that lens is.

Not sure if a time lapse can be IOTW but this just so so,so good!

thanks for posting.
