Thanks relaxvideo. I disabled resample in the event switches and also rendered my video in wmv in 1080p at 30fps matching my project which improved my video quality tremendously in my panning video clips; however, I'm still getting minimal motion blur. Definitely a huge improvement. I really appreciate your recommendations!

Something is off. Your pans aren't fast and yet your video is very jerky. In my opinion there is not enough motion blur in your pans. It looks like a very high shutter speed for the frame rate used.

I am afraid that the replies so far are pretty far off the mark: your problem has nothing to do with motion blur. As far as resample, if you are trying to create slow motion, disabling that will make the whole problem much worse, not better.

I downloaded the video from YouTube and it is clear that you have done something to some, but not all of the events. What I am seeing, both when I viewed the video on YouTube, as well as when I deconstructed the downloaded version, is a LOT of repeated frames, but only on certain scenes.

Your text crawl at the beginning of the video looks just fine, with no repeated (or dropped) frames. The first two scenes, tracking the boat, are also OK. However, the third scene where the drone pulls back to reveal the outriggers on the shore is full of repeated frames. One possibility is that you attempted to create slow motion, but either disabled resampling, which is the wrong thing to do, or you mistakenly used undersample to create slow motion.

So, go to that event on the timeline, right click, and see if either playback rate or undersample rate are set to something other than 1.0. If they are set to anything other than 1.0, change them back to 1.0.

Also, while you are in that dialog, make sure that resample is set to either "smart" (which is what I would recommend) or "force." You do NOT want it set to disable resample because if you attempt to do a speed change, then you will get repeated frames, which is what gives you the jerky motion when panning.

Johnmeyer and everybody who contributed to this thread, thank you for taking the time out to review my project. The video was shot in 1080p at 60 fps using Protune and highlight tag features on my GoPro 4 Silver. While filming, my raw panning video shots were going to fast and I wanted to create a slow motion effect to the panning on my project. You are correct that I disabled the re-sample event and decrease the playback rate at 0.5 to get the slow motion effect. The under-sample rate was set at 1.2 rate. It turns out that it did exactly what you stated previously. It created a jerky and blurring effect to my video. I adjusted the under-sample rate at 1.0 and playback rate to 1.0 which completely resolved my unwanted issues; however, it did not achieve the slow motion effect I wanted on my video because the playback rate was set at 1.0. I guess I have to update my gimbal firmware and slow down my panning during my aerial filming to achieve this effect in the future. I also have a much cheaper video editor called Wondershare which causes the same jerky and blurred effects but to a lesser extent as compared to Sony Vegas Pro 12.

If you shot the footage at 60p then you should be able to change the playback to 30p and get very good slow motion using Vegas.
What I suspect has happened it somehow you've caused Vegas to take only every second frame from your 60p footage and then with no resampling tried to make that playback at half speed.

I've shot 720p60 before and got perfect 30p slow motion from it using Vegas. Unless something has been seriously messed up in the later versions of Vegas or if you've done something very strange.

Was your project 30p or 60p?

Bob.

I stand corrected. I went back to my camera settings and I was shooting at 1080p at 30 fps not 60 fps as originally stated. The project on Sony Vegas was rendered in wmv in 1080-30p. So my playback rate at 0.5 slow motion is only 15p which can probably cause the jerky and blurred quality of my aerial footage while panning. I still plan to slow down my panning during aerial filming and I will try to shoot at 720p at 60 fps to hopefully correct this unwanted problem as per your recommendations. Thanks Bob! I'm glad you had success in prior projects to relay your experiences.

I went through my GoPro 4 Silver raw aerial video footage during fast panning and I found out that there was minor distortions of the original video shot at 1080p 30 fps. I believe that I was getting a "Rolling Shutter effect" causing distortions, blurring, and wobbling of the video from the fast panning from my 3 axis gimbal which was made worse post production on Sony Vegas Pro 12 when I put the playback rate to 0.5 to get a slow motion effect to my video clips. So shooting the video at a higher frame rate and lowering the resolution as well as using film panning instead of fast panning should resolve my rolling shutter effect. Thanks for all who contributed.

As far as I know the Hero 4 Silver does shoot 1080 at 60p and you don't have to reduce resolution.

Old Smoke, I think your original post on this thread was right on the money regarding shutter speed. During my last filming with the GoPro Silver 4. I shot the video without a Neutral Density or Polarized lens which I normal shoot with. This may have a affected my shutter speed on the GoPro 4 causing minor rolling shutter/jellowing effect with fast panning on the gimbal based on my review of the raw footage of each video clip. Your correct that the GoPro Hero 4 Silver shoots at 1080p60. I think I have to play around with 1080p60 and 720p120 when I pan with the gimbal. In order to avoid this problem I will do the following:

1. Pan slower
2. Use a ND or polarizing lens filter to slow down shutter speed of the camera on sunny days
3. Increasing frame rate
4. Decreasing resolution to 720p120 as a last resort or getting a Hero 4 Black which gives me the perfect reason to buy the upgrade. lol.

Sony Vegas Pro 12 probably exaggerated the rolling shutter effect when reducing the playback rate to 0.5 in order to get the slow mo effect. A lot of lessons learned. Thanks for your help.

I think what you see is a combination of all the above. 60p should be fine. I have a GH4 Silver too and I tried the 720 120p setting but the picture quality just isn't as good as 1080 60p.

As others have stated, in the future you should shoot using 60p if you think you'll want to create slow motion. Rendering that to 30p will create perfect slow motion, without any compromises or artifacts.

Faster shutter speeds will definitely produce artifacts when panning, and if you want to use fast shutter speeds in order to avoid unwanted blur when the drone is subjected to turbulence, you will then need to use post-production motion stabilization (e.g., Mercalli) to remove that turbulence, and then apply some post production motion blur to make the video look more natural.

If you want to do slow motion in Vegas using your existing 30p footage, then make sure to enable resample ("smart" or "forced"). Also, when doing slow motion, do not set undersample to anything other than 1.0. This is the wrong setting to use for slow motion. The only application I have ever found for undersample is for creating a "strobe motion" effect.

Rolling shutter is a problem for most of the GoPro-type cameras used for drones. I have not yet found a decent post-production fix for this, so the best solution is to use the best possible gimbal.

Try Mercalli 4.0. It can work wonders, but it is very, very slow for correcting jello effects due to rolling shutter.

Thanks to all who contributed! I just released another production video on YouTube today shooting with a GoPro 4 Silver at 1080p at 60 fps this time around instead of 1080p at 30 fps. Additionally, I panned slower and used a Neutral Density filter with excellent results. No more "Rolling Shutter!"
