Rendered Blur in video in video with SVP 13 (Picture in Picture)
Hi everyone
My first post, and I hope you can help.
I have spent alot of money on SVP 13 after months of research finding a good video editing tool, and to be honest it has been going great!Until about 2 weeks ago…. I started to notice (what I thought at the time) was an internet lagging issue. It turns out it is a possible rendering issue.
Setup:
SVP 13 – Used an application called “FRAPS” to capture COD gameplay on PC. In turn, I have the Logitech C920 Webcam recording the gameplayer / audio.
The Gameplay shows its exported as an .AVI at 60fps and the Webcam is 30fps.Used Sony Vegas to import all videos / audio files, trim everything up, disable reseample on all videos, and render as 60fps 1080p.
To give you an idea of the problem, see this video where I first found the problem:https://www.youtube.com/watch?v=Rk5WCXRM2dw
If you goto around 12:00 minutes, and see the action taking place on the screen, you see me getting blurry! Or out of focus I guess.I render using CUDA as well, but using just CPU, same results.
I am hoping someone could possibly advise on this.
By no means am I an expert in SVP, but I am very comfortable with the tool, and it has been used for all my videos, including XBOX which have been fine!
Thanks very much for any input or advice.
Be gentle 🙁

Hi Steve
Unfortunately, that is all I have.
Could there be anything else I could check in SVP?I have done a 2 min video at 29.97 (30FPS) and within the “Preview” of SV Pro, it looks perfect.
But Rendering at 30FPS it just looks the same …. in other words I have the same issue at 60FPS and 30FPS.

Right just an update….. I tried a completely different software capturing product and everything is clean and clear.
Yet… when I render in SVP, the SAME THING happens!This is not a FRAPS issue surely! 2 different pieces of software…. raw files look great…. render in SVP and its crap!
Could someone please offer some advice or guidance?
As mentioned above, please view the youtube video to get an idea of the problem… the issue happens when there is a lot of action on screen…. yet when viewing the raw file without rendering on SVP, its 100% perfect! no flaws! Crystal clear! -
I only saw brief periods of you PiP going blurry, so I will speculate what the issue is given you game footage source material.
This lower/blurry quality thing is common with people doing game footage and internet delivery via Youtube/Vimeo. Answered many times here. You have very fast movement with possibly high frequency detail and the bitrate delivery is insufficient to maintain detail at a given level. So when the bitrate becomes insufficient it can briefly go blurry and then recover when the source material calms down enough so that bitrate is not starved.
There is nothing you can do about this as you have no control over the Youtube/Vimeo encodes. It is what it is.
The bottom line is that internet delivery bitrate (which is low) only gives high quality if your source video material can get very good compression.

Hello Norman
First, thanks for your reply.
I want to be clear, that when I record the videos (before going through YouTube or Sony Vegas Pro), the quality is 100% perfect.I have put my video through a program called Adobe Premier and the Adobe renders perfect. The only issue I had was sound, but that is something I could ask my colleague to help with.
I do not own Adobe… but if it works on this product, and renders fine… then it should on SVP ?
Obviously, when the video gets uploaded to YouTube, yes quality is lost, but I am stating that when my videos are rendered with SVP even before going to YouTube, they are fuzzy!
I have also tested my rendering on another PC with SVP installed, and I get the same issue.
If this guy can do it…. why can’t I ?
https://www.youtube.com/watch?v=8CiQfMtSOgMI am gutted as I spent an awful lot of money on this software.

Since you are doing a small PiP, then make sure your final render quality setting is set to Best (project properties). Vegas only uses its highest quality interpolator (resizer) in Best. Vegas defaults to Good. The biggest difference between Good and Best is the interpolation algorithm.
Beyond that, I don’t know. I’ve not had a problem, but I have only used something like this once.

How are you obtaining your picture in a picture? Are you using pan/crop or track motion?

[Simon Weaver] “If this guy can do it…. why can’t I ?”
Probably because his HD video is 30p and yours is 60p which means at the same bit rate you will have 1/2 the quality that he has.
Seriously, I couldn’t even watch your video because all it did was stutter and pause and buffer because my Internet connection could not feed 60 fps. You should consider uploading at 30p and your quality will be better.

Hello Bob
Yes, that is correct.
What I do is record the actual webcam footage, then import into Sony Vegas, disable resample.
Next I use event pan/crop, maintain aspect ratio, then reduce the size of the video so I get the Picture in Picture effect.What I have also done then is used cookie cutter to reduce it a little more but creates a border. However, the problem occurs with or without the border.
When I do preview the video within the Sony Vegas preview window (full screen), it is absolutely fine. You could not see any flaws or issues.

Hi John
I have also done 30FPS – So to be honest, the problem is still there.
I am sorry your internet connection is poor.
To clarify again, the problem occurs on the “rendered” video output from Sony Vegas – Nothing to do with YouTube at this stage.Also, as mentioned in another post – If I preview the video that is ready to be rendered using the SVP Preview window (and I go full screen) it looks fine.
Because someone felt it was FRAPS, I tried a different product.
I can render it fine in ADOBE Premier Pro ….. but not Sony Vegas!Appreciate feedback about 30FPS – But it does not solve my actual problem.
Also, for the record I created a new project, removed the intro / outro and logo layer…. problem remains.If you have any helpful information please share.
