i have a sony fdr-ax53 shooting 4k at 25fps.

The footage on the camera when viewed there is no studdering on the panning shots but as soon as I transfer it to the computer to edit there is a shuddering.

The timeline is set up to match the 25fps. I've tried using the warp stabilizer in the affects but that doesnt work.

Any ideas how to get these shots smooth flowing like the original.

I'm running windows 10 fully updated with all video drivers updated to.

Thanks

Below is a sample file showing it

lowering the bitrate will not help.  What is the frame rate of your drone footage that you're comparing to?

Same 25fps and the timeline is matched.

I downloaded your original file and it played back fine on my M1 MacBook. There was no "studdering" but it did have that "look" when something shot in 24 or 25 FPS pans. Lower frame rate video like that always does that.

 

You're saying it plays back fine on your TV, does your TV have motion interpolation turned on? Different manufacturers call it Trumotion or Motionflow. This artificially smooths out your footage. This is an active process on your TV though. You can test this by disabling motion interpolation on your TV and seeing if the camera footage still plays back "smoothly."

My TV is 15 years old lol. Just an HD one.

If I shoot with camera at a higher frame rate then it won't match my drone.

What's your camera's shutterspeed vs the shutter speed of the drone? At this point I'm guessing that's the difference you are seeing.

And try shooting at a higher shutter speed and see if you get a smooth
pan. If so, then try dropping it into a timeline that matches your drone
footage and see what it looks like. There are a few things to try if
you're not happy how it looks in that timeline

worth a test.  I don't think this is a premiere problem, but a limitation of the camera....  bwdik...   Have you tried playing a clip transferred from the camera without importing into premiere in a program like vlc?

Will give it a go on that but it still did it on windows player.

Does this mean that a camera set at 25fps is no good for premiere?

Seems odd

No. There are more variables then framerate at play. You need to factor shutter speed into the equation here.

 

Like I asked earlier: What's your camera's shutterspeed vs the shutter speed of the drone?

If it's happening in windows player, the problem is the source file, not premiere.  

and Jeff's pointing you in the right direction.  try adjusting the shutter speed (which seems to be possible according to the specs on the b and h product page...)

Ive tried shooting at 100 shutter speed and imported into prmiere and made a lower proxy of the file but as you can see by the file below (adobe premiere) it is still shuddering.

I then did a screen recording of the windows player and if viewed small it plays will hardly any shuddering (win player small). But when you play it full screen it shudders (win player big)

Thanks

Can you do another test, shooting at 1/50 shutter speed, and do a pan and see if the issue persists? 1/50 is "technically" the correct shutter speed for 25 FPS.

 

Just to be clear, this issue you are experiencing has nothing to do with Premiere. Some quick research indicates a lot of users using XAVC cameras have this same issue.

Also, here's a great video talking about the details: https://vimeo.com/19603537

 

It's like your setting of 1/100 is too fast and creating zero motion blur which is mistaken for choppiness.

Will Look at the shutter speed but the drone is always on automatic.

Surely I would have to adjust the shutter speed constantly.

Guess shutter speed should be 50 as double the frame rate.

Yes, rule of thumb is shutter speed should be at least double. But the fact that the drone shutter speed is automatic does not mean that it doesn't matter.

 

In some cases, yes, you would need to adjust the shutter speed, depending on what you're shooting, lighting conditions, whether or not you have to match visual styles with another camera, etc. Unfortunately, a lot of people in this day and age think making good video is as easy as an iPhone commercial implies or that Premiere should just be able to fix everything. An expensive camera ≠ perfect footage.

I've just recorded at 100fps and will upload that to premiere and see what that is like.

To rule out Premiere you could try your footage in the free version of Resolve.

Find out what settings your drone shoots in (shutter speed, etc) so we have something to compare

It's Shoots in auto mode most of the time and I always pan slowly with it. Its 25fps 150mps.

Guess I just have to not pan with my other camera.

Guess film makers and TV crew have over 2k cameras.
