Gopro studio vs Sony Vegas Pro 13 (motion blur)

cmario wrote on 9/13/2015, 6:37 PM

Dell 8700
i7 4790 cpu 3.60ghz
16gb memory
windows 10
64 bit operating system
GeForce GTX 745
Gopro Hero 3 + Black
All video 60fps but scaled down to 30fps in editors.
Newbie at Video Editing

So here's the deal, I only shoot Gopro videos and have used the Gopro Studio to edit and render files to 1080 so I can watch them on my LED Smart TV. I'm using my blueray player with my portable hard drive hooked via usb port on blueray. What I have noticed is the quality between the two editors, mainly a slight blurring during motion. For example snorkeling on top of a reef with slight wave motion, the reef will looks slightly blurred when in motion on the Vagas but next to nothing on the Gopo studio, there is also a very slight drop in sharpness in the video. My settings on the Project Properties are custom (1920x1080,29.970 fps) Pixal format 8bit, full res.rendering Best. Rendering I use MainConcept AVC/AAC, Internet HD 1080p, custom template, Pixel aspect ratio 1.0000, Variable bit rate max24,000,000. Average 12,000,000, Enable progressive download is checked.

If there is anymore info I can add let me know. I hoping someone can help or at the very least point me to someone who has experience in getting video that will match Gopro Studios quality. On the down side I hope this problem is not due to something within Sony Vegas Pro 13's software.

Use GoPro Studio if it looks better to you.
At 12 Mbps GoPro and Mainconcept should be nearly identical.

Try and switch of resampling in Vegas; it may help. But why not render to 60p since you are not making a DVD?

I'll second trying Vegas with resampling disabled. The default Vegas "smart" resampling is IMO not smart when going from 60p to 30p. It still does frame blending vs tossing every other frame.

@OldSmoke. If I render at 60p the blueray won't play it, it's got to be 30p. I also selected" Disable resample" in Switch and it seemed to do the trick. Wondering if there is away of permanently keeping it that way, or do I have to do this on every video that has motion blur.

Thank for the reply

@NormanPCN. I'm assuming at 60p Smart resample doesn't show motion blur but at 30p it does. I need to look up what frame blending vs tossing every other frame means. I'm too new to all this stuff.

Appreciate the response! Thank you

@musicvid10. I did a side by side test of Gopro studio and Sony Vegas Pro 13 and found Gopro was slightly higher in it's highlights, in fact I preferred Sony over Gopro.

Thanks

Frame blending is means Vegas is taking two frames and blending each together to make a single new frame. This is something Vegas will do when changing frame rates from source to project/render settings.

Tossing every other frame simply means if you have 60p and are rendering to 30p, then Vegas is ignoring/skipping/tossing every other frame of the 60p source to get the desired 30p result.

The "smart" in Vegas smart resampling means Vegas is trying to determine when to do frame blending and when not to when the frame rate needs to be changed from source to project/render settings. When changing frame rate and not doing frame blending, Vegas simply duplicates or skips source frames to meet the desired frame rate.

If your source is 60p and your output is 60p then of course no frame resampling needs to be done. Your situation is a 60p source being sampled down to 30p. IMO, the better option here is for Vegas to simply skip every other frame which would be with resampling disabled.

It is not really correct to think of the frame rate resampling via frame blending as "motion blur". What you are seeing are ghosts of two image blending together and the ghosting will cause a blurring.

I thought you are connecting your hard drive to the BluRay player and not playing from an actual BR disk? If so, your layer may might well be capable of playing a 60p file; mine does.

Does your HDTV have a USB port? Does it support 1080 60p?

Vegas' smart resampling always combines and blends frames when the rates are not an exact match. You can even get this problem rendering to 29.97i if your source is 29.97 instead of true 29.97002997002997... although in this case the effect is exceedingly slight. Dropping every other frame when going from 60p to 30p is simply not resampling, so this is not what Vegas does. Vegas always tries to preserve as much information as possible from the source by using every frame. Since 60p source has two frames for every 30p output, it uses two source frames to produce one output frame.

This is another example of why a lot of Vegas users would prefer to have resampling disabled as the default.

By the way, 12Mbps is pretty low for 30fps 1080 material. 16Mbps is probably a good minimum, especially if there is motion. I'd probably use 24Mbps average.

Now that we know it is to be delivered on Bluray, you do need to use the Bluray templates, not the internet templates.
Now that we know something about the content, you do need the highest sustainable bitrates that still fit your media. 12Mbps is too low for water in motion, notwithstanding what i said earlier.
Oh yeah, disable resampling.

Actually, no we don't know. From OP's first post:

@NormanPCN. Thank you for the information it clears things up. There’s a lot to learn.

@OldSmoke. You were right the first time I am connecting my hard drive to the BlueRay player via the USB port on the BlueRay player. I checked with the manufacturer (Samsung) and they said only 30fps videos could be played. My VIZO SmartTV does not have a USB port and as far as supporting 1080 60p I’m not sure but will look into it.
I have not tried burning a BlueRay disk yet everything has been off my harddrive.

I don’t see the need to go to 60fps since NTSC is 29.97fps. I also thought 60fps was mainly used if you are into animation gaming?

@Chienworks. If so many Vegas users opt to disable resampling shouldn’t they (Sony) make an option to disable resampling once and for all instead of the user having to choose a file and disable each time he/she opens a file?

Chienworks wrote on 9/14/2015, 1:27 PM

One would think.

I guess the reasoning is that if you know you want to disable resampling you'll go do it. But, if it was off, for those very, VERY few cases in which it actually helps, people wouldn't know to turn it on.

The only fallacy with this is that people who need it off don't necessarily know to turn it off until they end up asking a question like this in the forum.
