Watch a short 600d test video, help the beginner with unknown problem

Recommended Posts

Hello everyone

 

Watch short 600d test video. Hand held and than stabilized in sony vegas. I stabilized it in mercalli v2, and it is even worse.

Problem is not in shaky video, but in, I dont know how to call it – high frequency trembling that you notice, particularly in stabilized video. This shivering, or sometimes slower “breathing or hearbeats" of video looks to me more like some weird distortions of whole image than regular shaky video. As I noticed this in my videos, I sometimes notice it in some others on the web also. Does anyone knows what is this and how to avoid it next time?

 

My video:

Also I noticed something similar in this video

vimeo.com   >  /groups/600d/videos/55359162

Its a short cut, but notice what the cup is doing on 21 seconds mark.

 

 

My setup is:

600d

magic lantern

flaat 10

1080p 25fps

18-55 IS II

IS off

well, it the meantime i learned this.
this distortion is called rolling shutter ripple effect.
the reason why it happens is because stabilization plugins have problems with cameras like dslrs which produce general rolling shutter effects.
for explanation check this video at 3:30 mark.

i guess i need better plugin or software.

 

tnx

Your plug-ins and software are fine, but it's best to minimise this rolling shutter or "jello" effect at source, rather than rely on fixing it in software. 

 

For this kind of shot you can use a tripod, then introduce a little camera shake in software afterwards for handheld feel. Or, if you want a less "jello" but till a real hand-held feel, use some kind of handheld rig for stability.

 

Plug-ins like Mercalli and Warp Stabilizer can only deal with a certain degree of shake effectively, the rolling shutter can be destructive, so if it's possible to eliminate it at the point of shooting, without software, that's the best idea.

 

Also, turn your IS on! ;) It's much nicer than plug-in based stabilisation on the whole.

i was confued because i know that rolling shutter is problem when you pan around like crazy. this is first time that i see that it can be a problem when taking static handheld shots.. crazy..  this is bigger problem than i tought...really limits your options and picture quality. i will try with is on and see if it helps. also this after effects stabilization looks way better than vegas one. some professional cameramen told me to lurn IS off because it can create some distortions and that it was designed for photography and not video.

 

tnx

Yes it's a huge issue with CMOS sensors, truly the best way to get rid of it is on set, not in post, by using rigging. IS does create slightly jumpy shots sometimes, but that's better than camera-on-a-jelly style wobble.

 

Did you try switching it on and judging for yourself if you like the picture better? Last shoot I was on at the Tennis Masters in London the IS stayed on with the Canon 28-300 all the time. Switching it off was much, much worse... it's certainly better than nothing. best make your own mind up... pinch of salt and all that.

That's nonsense. IS will indeed improve the image. Lenses are optical stabilizers and they reduce the jitter before the images are recorded. This will reduce the jello effect as well. Just try it out, do a comparison recording the same stuff with IS on and off and judge for yourself whether it creates distortion or it makes it all look smoothier.

You want to see the difference between IS on and off?  Watch my video below.  All handheld, I forgot to turn IS on until 02:50 in the video.  Huge difference in performance, and my hands were shaking all over the place.  Again shot all handheld for the whole hour!  Ouch!

      This is a promotional reel I've just made for the small videography business I'm currently setting up (one-man-band doing local community organisations, weddings etc). Everything in it was shot on low-end/cheap cameras, several of which have been discussed and compared extensively on this forum over the last year or two. To boot, other than the Tokina 11-16mm all of the lenses were each bought for under $300.
       
      After a couple of enquiries about the gear I used for this reel, I've decided to add subtitles to show each camera (and lens) each shot was taken with. Just click the 'CC' button in the Vimeo play bar to turn the subtitles on.
       
      I'd welcome feedback on my reel, but this is mainly posted here in the hope it might be of use to others:
       

       
      Sorry the subtitles aren't synched perfectly to each edit (it's not easy with Amara). You'll work it out though I hope ...

      I'm starting to set myself up a small videography business: just a one-man-band doing local stuff - community group promos, weddings, etc. I'm still working on the website (www.lintelfilms.co.uk) and have just finished the 2nd draft of my promotional film. I'd really appreciate your feedback on the film. I don't mind at all if you are brutal!

      Hi,
      I've just finished a shoot for a UK based car show, focused on the VAG scene.
       
      I focused my efforts on emphasising the social side of these events. 
      I shot on a 600D (with Magic Lantern, for zebras), and used a mixture of the 50mm 1.8 and the Sigma 30mm 1.4. With a few 18-55mm kit lens shots thrown in for wides.
       
      http://vimeo.com/77848159
       
      Whilst the kit's very modest, I'd be interested to hear any feedback.
      I'm looking to sell my 600D early next year and upgrade to a 5D MKIII. Keeping the 50mm 1.8, and adding Tokina 16-28mm 2.8 PRO FX for the super wide angle shots, and possibly a Canon 85mm 1.8 for the nice closeup textural stuff.
      A big push for the upgrade is the sensor size, to allow me to go wider. and the low light performance. As, currently I struggle to go past 800. And even at 800 there's a fair amount of grain.
       
      Any thoughts on the video, and my incoming kit upgrade would be ace :)
       
      Huge thanks in advance.

      My serene short macro film.
       
      Mostly shot on Pentax-A 100mm f4 macro, with very close up shots using a reversed Sigma 24mm f2.8 super wide II.
       
      I used my k-5 for tests and stills, but used a Canon 600d with Technicolor cinestyle installed for the actual shoot, as the dynamic range is greater, and it has manual controls. The lenses are attached using a canon-pentax adapter, which can be bought from Ebay for £10/$15.
       
      To get closer I used a set of 50mm extension tubes, and sometimes used the Canon 600D’s 3x digital zoom (which is still full 1080p HD, a useful feature and no extra depth of field loss!)
       
      The film itself is rather light on narrative; it’s just a progression of – hopefully!  â€“ interesting shots.
       
      Hope you like it. I’m happy to answer questions on how I did specific shots and it’s always good to get feedback.
