Nick, thank you for popping in!

1. I'm on Vegas Pro 14, build 161

2. The jutter happens on regular speed clips, but I see the jutter also if I slow down rhe speed.

3. I have tried both 50% and other values

4. Yes, I'm sure it takes place on rendered video. In fact I've tried rendering with different codecs, with varied success, but the problem is I don't really know which to use to get the most compatibility, for distribution purposes (online, peer to peer etc...)

I also read somwhere that if Gopro studio is installed I should get access to Cineform codec, but alas it is nowhere to be found. (I installed Vegas Pro 14 on a pc which already has Forpo Studio installed....)

thanks again for helping out!

best regards,

Paul.

What is the spec of your computer? (you can follow the first few components of the spec in my profile as a guide for what info to post.. CPU, GPU, RAM... don't need the whole lot)

You could try posting some sample footage somewhere like the public folder in a dropbox account for others here to test.

The GoPro Studio download is here. I believe the codec should show up in Render As > Video For Windows > Customize Template... > Video format. I don't have it installed, so it doesn't appear in this screenshot, and I might be wrong.

Hi Nick,

With my limited knowledge I have been able to find the following specs:

CPU: Intel i7-2600K @ 3.4GHz

GPU: AMD Radeon HD 7600 Seres

RAM: 16 GB

O/S: 64 bits, processor x64

OS: Windows 10 Home

I have posted a test clip on Dropbox:

https://dl.dropboxusercontent.com/u/25183633/GOPR0028.MP4

This is a clip straight out of the camera; no rendering done.

Thank you for the help on finding Cineform codec! I tried it out but my pc funnily enough would only play back the sound on the rendered clip, which I find very strange...

Thank you again,

Paul.

The clip plays smoothly on my computer in VP14 and VLC and your computer doesn't look like it is underpowered.

Take a look at this rather old list with regard to fluent playback: https://www.vegascreativesoftware.info/us/forum/fluent-preview-playback--100487/#ca615994

On top of those tips, try with GPU acceleration on and off in Options > Preferences > Video (restart required). Also apparently now in VP14 you can try increasing the dynamic RAM preview setting there.

Also look at this that I wrote before VP13 came out: https://www.vegascreativesoftware.info/us/forum/why-does-my-rendered-video-look-bad-quality-troubleshooting-basics--103361/

Thanks Nick.

The thing is that the clip I uploaded is great quality, but it is staright from the camera. What I cannot seem to manage is to render te clip into anything decent (ignoring the high end codecs- one rendered a 1.7GB clip from this original using the HD 720-50p YUV template in Vegas).

What I find more disturbing is that using a programme called Splice on the Iphone/Ipad the quality of the renders from Gopro clips (in video productions including stills, Gopro clips etc...) is pretty stunning (viewing both on devices and my PC) and basically that is what I'm hoping to emulate in Vegas. So there must be a way to get decent renders, even though I can´t fathom it out as yet.

Thanks again for helping me along.

Best regards,

Paul.

Why don't you use mp4?
I've rendered your file with the Internet HD 1080p template only changed to
25 ,000 PAL and progressive scan, project proberties: Disable resample
Result is a 90 MB mp4 file in good quality

Thanks for the suggestion Quitter. I'll give your suggestion a try!

here is the file: https://www.dropbox.com/s/ow7ilbjq67wztc2/test.mp4?dl=0

Why not keep the 50fps of the original? You'll get a smoother, more "real" or "TV" look with that, and YouTube support it now. Also, probably no need to pillar box it (black sides) to 16:9. Just match the 1280x960 of the original and let the player (or YouTube etc.) deal with that and save yourself a little bit of bit rate.

Here's 2 options for you. They both generate a file of 92MB, which is slightly over the 86MB of the original. That fast moving snow is really really challenging for these types of encoders. If you skimp on bit rate the snow will start to melt in strange ways.

FAST OPTION - Sony AVC/AAC - Render time 37 seconds on my PC

QUALITY OPTION - MainConcept AVC/AAC - Render time 91 seconds on my PC

Save those as custom templates. Note that you will have to manually type in the frame rate of 50 in the MainConcept template as it doesn't appear in the drop-down menu. It doesn't look like you can because there is no "custom frame rate" option, but you can.

I enabled the deblocking filter in the MainConcept encoder because it was blocking quite badly (see the edges of the shadows on the snow), but that does cost some detail elsewhere. You can try disabling it and see which you prefer. Stack the rendered files up on multiple tracks on the timeline and compare at Best (Full) Preview Quality by muting the upper tracks on by one.

In both cases you can improve quality further (at the expense of file size) by increasing the average bitrate (or just "bit rate" for Sony).

In reality there is not a huge difference between the Sony and the MainConcept, unless you're a pixel peeper.

What is your delivery destination for this? YouTube? Offline viewing? On phone? TV? etc.

A huge thanks for helping me out with this!

Quitter, I checked out your render and it still feels under par with what I am seeing from Splice (I actually rendered out a test video containing a still, an iphone clip and the sample clip I posted, including a touch of slow motion to understand the outcomes better.

Nick, I tried your solution on the MainConcept encoder and it does seem to provide a fairly good quality video, although there is some jerkiness in a panning shot. However, it is much better than what I had achieved so far so a big thank you!

If you are interested in a comparison between what an Ipad can deliver with the app Splice and what I have obtained through the MainConcpet encoder these are the clips. Please bear in mind that they are not the exactly the same.

Mainconcept sample:

Splice form the Ipad:

Any further suggestions are of course more than welcome!

Thank you once again!

I've just rendered, as you wanted in 25p, fast without any great changes. To see what happend with the jutter/ghost like effect. (I would also prefer 50p.)
As Nick says, there is more to do (e.g. 50p, a higher bitrate, match the format of the original...) to get better results.

The link "Splice form the Ipad" doesn't work
it works now 🙂

Quitter, I checked out your render and it still feels under par with what I am seeing from Splice

I have compared the results
Do you really mean your Splice render is better? (left is your splice, middle mine, right your mp4)

Quitter,

No I son't think the render from Splice is better...Not after the last exercise. It was way better before though! What I really wanted to check out is how the renders "behave" with mixed media. With Splice it's no fuss: just add mobile device video clips, stills, music, GoPro or whatever, adjust lengths or speed settings, add (or don't Ken Burns effect on stills pick render setting and click to render. NIce hobbyist solution while away.

I have been using Vegas on and off since version 3, and recently upgraded from v9 to 14. In the good old days it was pretty simple to add stuff and render away, be it for DVD or AVI for computers and so on. With the advent of HD, framrates, different resolutions, codecs and the ubiquitous mobile devices it all seems to have become more complicated.

Resampling for example was analysed by Vegas in the good old days. If the clip needed it Vegas would apply it; if it didn't it just left it alone. I am actually partially "guilty" for the "smart resampling". In the older versions, sampling would be turned off by defect. However given that Vegas smartly identified whether resamling was needed, I suggested on a forum that it should be enabled by defect and let Vegas do the right thing, and the suggestion was taken up by Sony.

Now I am fairly confused as to when resampling is to be enabled. Do different framerates on one timeline need it? Do varitions in speed require it? Do variations in speed require it when you have a 50p framerate clip on a 25p timeline and you want to slow the speed up by 50%? etc etc...BUT this is a different story on which I have yet to read up on, since there are bound to be loads of literature scattered around all the forums.

Splice is actually quite a neat programme for quick hobby edits on idevices, delivering pretty decent results if viewed on that type of screens. It was actually recently bought by GoPro, who are determined to provide an front-to-end solution to the average Joe.

Once again thank you for all your help. Now I can actually colour correct and stabilise some of the footage!

All the best,

Paul.

Asking again, what is your delivery destination for this? YouTube? Offline viewing? On phone? TV? etc.. Are you planning to add FX, titles etc.? This affects our recommendations.

If retention of quality is paramount and you're not bothered about FX etc., just cutting/joining, then you might consider smart rendering (i.e. no recompression) and joining with TMPGEnc Smart Renderer or FFmpeg. (Edit: Or maybe even the GoPro app???)

@PDB

I created this video in Vegas 14 and Handbrake that closely matches the parameters of your original file except:

Frame Rate = 25P

Slow Motion = 1/2 real time

Do you see judder in this video?
