Wrong shutter speed...DOH!

[zagnut]

Hey, it's been a while since I posted here. Moved back to Detroit from WA and finally got settled in.

On my way back though, I stopped to enjoy some scenery in the Badlands. But silly me was so focused on the scenery, that my cam was set to Tv at 1/48.

This lead to some unwanted smearing. I'm curious if there's anything I can do to clean the smearing up.

Would going from 24p to 60p, via motion compensation and interpolation, clean this up (I'm doubtful on this, but thought I'd ask)? I've also heard of something for AE and Premiere called Reelsmart Motion Blur that may help.

**EDIT**
24 to 60 through the method I mentioned is neither feasible (processing at .5 fps) nor does it look good. However, I did 24p to 60p with Tmpgenc and the initial result isn't bad. I'm reluctant to say it looks better, but possibly.
Any suggestions guys?

1) Why would 1/48 would lead to smearing? Never experienced it with that setting on my HV...
2) I doubt it would be possible to clean it, from what I've watched about video smearing, it looks more like reflections in the lens. I doubt it would be possible to "clean" the image.
3) Interpolation won't change much, as the info is already in the picture..
4) Motion blur would only stretch the smearing I guess...nothing better in that case.

Not sure to be honest. I'm 99.9% positive the cam was set to 1/48. It is possible it was set to 1/24, but pretty sure it wasn't. I wish there was a way for me to tell what the shutter speed was. Only happens on pans, which weren't exactly precise due to not using a tripod. I've looked at the footage frame by frame and it's not rolling shutter.

It's caused by one of three things; A - My horrible inability to keep a steady hand, 2 - Shutter was actually set to 1/24 (ACK!), or 3 - pulldown removal from 60i to 24p via NeoScene.
About the latter possibility - I have an HF11 and it records 24p in 60i (24PF). I was shooting in 24PF. I don't think removing pulldown had anything to do with it. I'll have to see if I still have the original footage.

I'll have to see if I still have the original footage.

That would be at least, the best solution: work with the original source.

Come to find out, I don't have the original source any more. Bollocks.

You're over analyzing. From now on just shoot at 60i unless you have a good compelling reason to do otherwise. It will save you a lot of headaches.

Additionally, don't pan either. Unless you have absolutely positively no alternative. It too is more trouble than it's worth, and add little or nothing to the aesthetics of the shot. I know that's not what you wanted to hear, but that's my philosophy nonetheless.

I had something similar happen to me shooting a little league event on a really bright sunny day using TV 1/48, and I was too a little confused as to the "smeary" texture the footage had- like you said, similar to 1/24. Too much light is too much light- once you go over f5.6 at 1/48 with the HVXX, it can get unwatchable very fast.

I've found that bumping it up to 1/60 or 1/100 gives you a nice look when it's really bright- not too fast, and certainly not smeary. This is exactly why I use TV mode- you get the control, and I don't personally like the look of 60i footage anyway. Furthermore, for you cinemode homers, you can set the video setting to neutral and achieve a nearly cinemode look while still having control of the shutter. I've done some really artistic footage with the shutter at 1/250 all the way to 1/2000 and as long as you have a TON of sunlight, you can get all kinds of cool looks- (like the famous "Saving Private Ryan" look)

It's funny because so much time has been spent over the years discussing how to make the HVXX perform in low light, yet I've read very little on how to use the cam best when there's too much light!

For those situations you use a ND filter. (And/or a CPL to cut light from reflections.)

Nice info
