Sony Vegas Eating Up To 100% CPU
Hey everyone, I’m fairly new to Sony Vegas and video editing in general. I took the Google crash course on video editing and I’m getting very mixed results due to not having a firm grasp of all the concepts.
System Specs:
Intel i7-4770k
16GB DDR-3 2133 RAM
GTX970 Graphics Card
2 Solid State 250GB Drives.My son and I are big gamers and we just started using OBS to record our gaming experience, using Vegas Pro 12 to edit videos and put them on YouTube.
I have tried MANY settings for OBS output, varying bitrates, frame rates and screen resolutions outputting in an MP4 format so I don’t need to convert the FLV files OBS outputs into something that Sony Vegas can accept.
However, the issue seems to be that any time I add a video (especially a video of about 20 minutes or more) to Sony Vegas, the preview lags. I have set the preview all the way down to Draft -> Quarter and it still lags. Even worse, if I pause the preview to make an edit, hit S to split the video, etc, Sony Vegas takes up a variable amount of my CPU from 80-100%.
There are times where the preview doesn’t work at all and the audio plays but no video.
I have tried disabling/enabling GPU Acceleration.
I have tried disabling/enabling Multi Core threading/rendering/playback
I have tried changing Dynamic RAM anywhere from 0 to 10GB (10240MB)
I have my preview settings on Draft -> Quarter (lowest possible)
I have changed the priority settings in task manager for Vegas to both High and Real Time in an attempt to give it more resources to no avail.When I go into my task manager, I can see my CPU usage is crazy high, but the thing I find odd is that my RAM usage sits around 3-400MB. I was always under the impression for video editing and rendering I needed more RAM, I honestly thought that would be my bottle neck but it’s not.
On an aside, which may or may not help remedy the situation…
1.) If there are certain settings for OBS to output/encode with that Vegas likes more and will make things smoother I’m up for suggestions. Still looking to Upload to YouTube between 720P and 1080P if possible.
2.) If there is a certain file format such as MP4, AVI, MPEG-2, etc. that would be better to edit with through Vegas I’d be more than happy to convert to that file type as well.Thanks in advance for anyone willing to help or make suggestions!

Have you tried matching your project settings to your media settings?
For example, dropping 60p media into a 29.976 project will use a lot of CPU cycles trying to conform the frame rates. Likewise recording at a resolution that’s different from your project resolution will require extra processing to resize. I would make sure that your project and media match.

Thank you for the reply 🙂
Unfortunately I have done so with no result. Or I should say, at least no noticeable result.
This issue is quite frustrating to say the least.
Thanks again!
If you have any other ideas I’d love to hear them 🙂

Can you output Motion-JPEG (MJPEG) format in an AVI file? That might playback smoother.

If you mean output from OBS, no. Sadly it’s limited to MP4 and FLV file types. That being said, I could just use a video converter and change that? Or would that do something to file integrity/encoding that would make it worse perhaps?

It sounds to me that your problem is that OBS is doing variable frame rate recording, which Vegas and most other editors do not like. I use Mirilli’s Action and when recording to MP4, the frame rates of files loaded into Vegas will vary. For recording to avi, there has not been a problem. When you import your file into Vegas, what are its properties? A screen shot would be helpful. Even better, if you could upload a short sample clip to something like Dropbox, others could take a look at the file. This seems to be a common problem, especially with game recording software and video recorded on cell phones.

Another option would be to take your MP4 file and re-render in Handbrake, making sure that your output has a constant frame rate. In fact, I’ve done this with the Mirilli Action MP4 files and it does work. Vegas then sees it at the proper frame rate and all is well. Since you have an Intel processor, you can use quick sync in Handbrake and the render will be very quick. The only downside is a generational loss and the time spent to re-render. Something else to consider.

Yea, the bottom line is that the video needs to have a fixed frame rate (if the problem is a variable frame rate) and if you have to transcode it to get that then so be it. Unless you can make the video compliant for editing to start out you will need to re-render it.

Wayne,
When you say “upload a short sample clip”, do you mean to split my 30 minute video into a short 1 minute video, render it as MP4/MPEG2/AVI and upload it so you guys can view it? Or make a NEW short video and do the same?

Thanks everyone for the replies and the ideas.
So, my question is this:
OBS has the ability to set Frame Rate at whatever I want. So, lets say I set it to 30. However, the Bit Rate is variable up to say 1000kb/s. Is that effectively saying that the Frame Rate is also variable? Would increasing/decreasing the Bit Rate make my rendering slower/faster?
The other side of the coin is that MANY YouTube people use OBS. They swear by it and the bulk of them use some version of Sony Vegas. I, being new, obviously used their suggestions and settings and have the results I do now.
So, as per the suggestion, re-rendering my MP4 into what format? MP4 again or MPEG2 or AVI?
Thanks again for all the suggestions, I feel like I’m learning a lot! 🙂

Or make a NEW short video and do the same?
Yes. Just make a new short video a couple of minutes long in the same way you’ve recorded in the past.
