"Smooth Slow Record"

    I was wondering the thoughts all you fellow FS100 users have on this function.
    I've had the chance to play around with the function a few times at work, and it
    usually doesn't result to anything more than just having a fun time watching
    things slow down infront of you.

    I have shot two demo video's that test the slow mo functionality of the camera.
    One where i smash an old computer monitor office space style, the other where
    i just jump around and play with my bosses dogs.





    The footage looks like it was shot on a crappy cellphone camera, yet I still feel the
    function has it's useability. At work we have used the function in dozens of corporate videos,
    commercials, and other such things. It's ability to capture things at a quicker frame rate than
    most corporate video shooters are used to working with now brings a whole new element
    to low budget video.

    I guess the main point to this post is. Are there any other shooters out there in Philip Bloom land,
    that sprinkle in "smooth slow record" footage into their video's as I do?

    I don't, but I might if quality was not an issue. I will probably use it on a pitch piece this month. Obviously for something going to broadcast or a wide audience, I would not use it.

    I found myself saying the exact same thing until recently. We shot videos for a local awads show, and i can think of three
    situations where we used the smooth slow record for no longer than 2 seconds.
    Once where we had an extreme close up of a sewing machine to show the sewing needle slowed down, another time to show a basketball dribbling slower than it normally would,
    and lastly we used it again for a sewing machine, where we did a rack focus from the needle to the operator shot all in 3 seconds, which is stretched to 12 seconds, and then with the time remapping added brought down to two seconds.

    I agree that it's nothing more than a "gimmick" but I feel that by utilising this tool in the right manner can bring up the
    production value to the rest of your low budget films, as opposed to using twixtor.. which destroys your footage.

    I like the standard over/under crank features of the FS100, but not this feature. I played around with it when I first got the camera and quickly dismissed it. I just couldn't get past the low quality
  6. My incredibly dull test with S&Q motion. Zeiss ZF.2 lens with Novoflex adapter. f4 I think. Only used the unnatural fluorescent lights in my office. One pour recorded to both the Atomos Ninja, and S&Q. Both dropped into FCPX and trimmed poorly. I remember hitting a few check boxes in FCPX, don't ask which ones.

    Sadly, Vimeo compression killed some of the amazing details, but you can (why on earth you would is beyond me) download the 569mb original. I should offer a prize to anyone that can sit thru all 4 minutes.

    I agree with Matt, I am going to try some testing on the greens this week and I will post the video.

    Shredding cabbage in slo-mo - awesome! :D

    Nwpuld you use this instead of overcranking?
  11. Matt Davis Administrator

    In normal circumstances, I'd use normal overcranking (S&Q) AND a software retimer (Kronos, Twixtor et al).

    Smooth Slow Record is a bit of a 'feature' in certain Sony cameras for some time, so I can imagine Sony engineers throwing it in, or building on a design that already had it in. Before the Optical Flow stuff in Motion et al, retiming software was incredibly expensive and complex. Here was a cheap way of doing it IF you could get your timing right and IF you can put up with the lower resolution.

    If you really really needed to get the best movement out of something quick, then perhaps yes I'd be tempted to try out Smooth Slow Record, but as you'd see in the movie above, you'll have to deinterlace it thus reducing resolution even further, to get the effect.

    So right now, I'm sticking to S&Q. Until I can afford an Epic, that is.

    no the golf greens Matt lol but good one lol :)

    I use the S&Q mode a lot and find the slow motion within it to be excellent, but not the Smooth Slow Record. However, it is a really great tool to have in some cases where no one is really concerned about the finished quality, but more the content. Example, I recently filmed my friends golf swing, from multiple angles, burned a blu-ray and gave it to him so he could see exactly what we were talking about when he was taking his club to far inside on the backswing, and then seeing his "out to in" slice swing.....and then watching the ball slowly take off (on the wrong path :) .... so for those kinds of situations, it's great to have that functionality built into the camera. I'm sure if it wasn't there, everyone would be complaining that it was missing.

    If I'm not using the S&Q mode, I have found Twixter to do a descent job most of the time for slow motion.

    Matt, thanks for the Sneak Peak, looks great!
    Quick question, have you used Twixter (or similar) on footage you shot in S&Q mode (50p played back at 25p) and then applied a 50% slow mo in Twixter for a 25% of original? I haven't tried it yet, just curious how the S&Q mode final footage takes to further manipulation in post.
  15. Matt Davis Administrator

    The final shot of the guys bodysurfing (just before the chicken stuff) was shot SSM, then I used Kronos after that - Kronos, from The Foundry, is pretty much on the same level as Twixtor, though I am not an expert in either.

    I'd better state that, in Kronos, I got better results from slightly motion blurred footage and that stuff shot with a high shutter speed fared less well... I believe the complete opposite is true of Twixtor. TETO rules apply: test early, test often.
  16. Clint Regehr Not quite so new!

    Matt, thank you, that footage looks great. I am going to have to give that a try.

    That is also very interesting RE the difference between Kronos and Twixter in reference to the shutter speed and motion blur of the original footage. I only have Twixter, but it seems to work well for me with motion blur as well. We do an annual HS Football (US version) highlight video, and we sometimes get too much motion blur on bright sunny afternoon shots, so we turn a lot of those clips into slow motion using Twixter and it makes it look much better than the original. Thanks for the info. This is a great forum btw.

    Yea, I stick to the normal S&Q feature... looks wonderful. Haven't been able to really fidn a use for Smooth Slow Rec.

    Since we're on the topic of slow motion, I guess I'll take the liberty to ask a minor OT, but related question - my apologies in advance:

    Is there a video quality difference between shooting S&Q 60fps in a FX 1080/24p container and bringing it into a 24fps timeline ... and shooting 1080/60p PS, bringing it into a 24fps timeline, and then telling the software to play it back at the correct speed to achieve 2.5x slomo... ??
