Motion blur when rendering video and I cannot figure it out. (Sony Vegas 9)
on May 1, 2014 at 2:14:42 am

Before posting this message, I browsed and searched google all over the place, but no matter what I do I cannot find the answer so I appreciate all of your help.

Here is the problem (Sony Vegas 9):

My video is taken from my Sony camera and is a .mts file in AVC format.

More properties of the video file:

General
Name: 00111.MTS
Type: MPEG-2 Transport Stream
Size: 27.36 MB (28,016,640 bytes)

Plug-In
Name: compoundplug.dll
Folder: C:\Program Files\Sony\Vegas Pro 9.0\FileIO Plug-Ins\compoundplug
Format: MPEG-2 Transport Stream
Version: Version 1.0 (Build 226) 64-bit
Company: Sony Creative Software Inc

If I view my video as "Preview - Half" it looks great. But when I preview my video in "Good - Full" mode or "Best - Full" or "Preview - Full" it has this blurry motion blur applied to it. You can see an example here:



And no matter how I render it as a WMV file, it ALWAYS ends up blurry. Here are my render settings:

Windows Media Video V11
Mode: CBR
Format: Windows Media Video 9
Image Size: (Keep Original Size)
Pixel Aspect: 1.000 Square
Frame Rate 29.970 NTSC
Second Per Keyframe: 5
Override Default compression buffer (seconds): 5
Video smoothness: 75

Bit Rate: 15 M
Video Rendering Quality: Good (I've also tried Preview and Best)

Any ideas on why this is doing this? I also tried disabling resample as well by right clicking on the clips and choosing "switches ---> disable resample"

Thanks for your help!

Go to View and double check to make sure that the Video Bus Track
is not selected, and no Motion Blur Amount is on it.

I checked this just now and I do not see any indication of motion blue in that video bus track so unfortunately I do not think that is the problem. :(

And when you play it back on WMPLAYER?

Yes, it is the same result in windows media play: blurry motion blur. :(

I still can't figure this one out. It seems like I've tried everything.

By the way, it's build 895 v9.0c if that helps.

Thanks again.

[Ryan Thomas] "Video Rendering Quality: Good (I've also tried Preview and Best)"


O..K..

I don't think you have motion blur. I think you have a DEINTERLACE issue going on. You are going from INTERLACE to PROGRESSIVE and somehow the render has to take into account for this.

Try and RIGHT click on the Event and use "Reduce Interlace Flicker" and render a small piece. What do you Get?

Also, what are your settings in Project Settings for BLEND Fields?

I don't think this is Motion Blur, but rather somewhere within your workflow going from INTERLACE to the WMV you are needing Progressive.

Interesting . . . .

What BUILD of VP9 are you running?

Thanks for the help. I am using Sony Vegas Pro 9.

When I go to render the WMV file, I notice it says it has these render settings:

Audio: 96 Kbps, 44,100 Hz, 16 Bit, Stereo, WMA
Video: 29.970 fps, 1920x1080 Progressive, 5 Mbps
Pixel Aspect Ratio: 1.000

You'll see it says PROGRESSIVE but I do not know how to change it. It seems like I am unable to for some reason with the WMV file extension.

Also, for deinterlace methos, I have "Blend fields" set by the way.

Honestly?

Either choose another template....

Or use YADIF, a freebie deinterlace s/w. I've had it Plugged into Vegas and have used it a coupe of times.

Sorry, if it's the Interlace to Progressive ( none interlace) deinterlace issue then I don't know what else to suggest.

When I have had this problem I turned off the BLEND fields to NONE and it cured it..

Hey Graham, I believe I FINALLY figured out the setting that was causing the problem. Here was the fix for me (for now at least):

If you are having blur issues, go to:

File --> Properties --> Set Deinterlace Method to "Interpolate fields"

So far, it is working. Any ideas WHY this setting works though?

Thanks again for your help!

Sure. Any Motion under these circumstances will blur. But that is NOT motion blur that the Video Bus gives. It IS part of it, but your requirements are for removing INTERLACE to DEINTERLACE.

Sorry, I'm still trying to wrap my head around this. So, setting Deinterlace Method to "Interpolate fields" did what exactly? Me confused. lol

Sure. Try this from WIKI Deinterlacing

Enjoy - It has pictures too!

It's important to realize what's happening here. You have a 1080/60i video that you're rendering to 1080/30p (well, technically 29.97p, but let's not worry about that).

What you have in that interlaced video is two temporal fields making up one frame. The first one has 540 lines of video at t = 0, the second has the other 540 lines of video at t = 1/60th second. In a true 30p video, you have the full frame changing every 1/30th of a second, in a 60i video you have half the frame changing every 1/60th of a second.

When you preview at half resolution, you're eliminating half of the scan lines -- thus, one of the two fields. So you're never going to see the effect of interlaced video converted to progressive. And in fact, one of the ways that conversion is done is to simply toss out one of the fields and double the other... so you only have half the vertical resolution, but no temporal effects. And keep in mind that you have to view at Good or Best quality to get a preview of the de-interlacing method, as well. Draft and Preview don't do this extra computation.

When you chose to Blend Fields, that's taking both fields and just merging them together. So you get full vertical resolution, but if there's much motion between the fields, you'll see the effect of that motion, in artifacts like "mice teeth", which zoomed out is that ghosting look you see.

When you select Interpolate, it works as I mentioned above... it tosses out one frame, and just interpolates the missing lines in the other by averaging previous and next lines together to fill in. So you have lower vertical resolution, but no problems with motion.

There are certainly more sophisticated de-interlacing methods out there in the world. It's quite possible to use motion detection between fields to use a hybrid of the two methods, or even motion tracking to detect moving regions and re-align them for the unified image. You have to look at plug-ins for better de-interlacing methods. Sony's got the two basic methods built-in.
