Serious lag on good PC??
on Nov 18, 2015 at 1:04:35 am

So I recently have started editing a project shot on an Iphone 6 at 1920X1080, and am editing in Sony Vegas Pro 12. The problem is, I'm seeing some SERIOUS lag while previewing. The files aren't super big, with the largest being about 250 mb. I have a AMD FX-6300 six core processor with 16 GB ram, a 1TB hard drive, and a GTX 660. I get a relatively fast editing experience on other projects. Is it the fact that it's Iphone footage, because Vegas is just acting weird, what? I'm seriously confused, and it makes editing these things dang-near impossible.
Thanks,
Jake

The problem is just simply because of those iphone videos.
They uses a codec that Vegas doesn't recognize and interacts well with,
that is why you are having that issue.
Vegas Pro 13 has many improvements in that area however.

I would run the files through ffmpeg, re-writing the files to a new container. If that does not work, convert the footage to hdcam-sr-lite or xdcam-ex. Those formats will edit much smoother and with less system overhead.

[Jake Russ] " I have a AMD FX-6300 six core processor"
That's not a very powerful processor for video editing. It is slower than an Intel Core i5 (see for yourself: "Core-i5 3570K vs AMD FX 6300") and we generally recommend a Core i7 for editing AVC/H.264 which is what the iPhone files are. So an Intel Core i7 would certainly help.
[Jake Russ] "...and a GTX 660"
NVIDIA is not the best GPU for working with Vegas Pro. The GPU acceleration in Vegas Pro is based on OpenCL which NVIDIA cards are not very good at. You would be much better off if you had a ATI Radeon HD 5870 (around the same age as your GTX 660)

Finally, Vegas Pro doesn't do well with QuickTime MOV files because it uses a 32-bit version of QuickTime for Windows to process them. Converting them to a different container is a good way to avoid this limitation.

Overall I'd say your computer is not optimized for working with AVC/H.264 Video in Vegas Pro and if you really want to fix it, you should purchase an Intel Core i7 Hex Core with an AMD R9 295x GPU for working with Vegas Pro. For now, try and transcode the AVC/H.264 QuickTime files into an MPEG4 container and see if it makes things better.

Yeah. The problem is that I don't have a massive load of money to throw at a new PC, I'm a highschool student, and I can't spend 700+ dollars on a GPU, and the 300-some dollars it would cost for an i7...
Oh well. Thanks anyways, I'll try converting them.

Converting them to MP4 files should help with the lagging because Vegas Pro will use it's native MP4 support for playback instead of QuickTime.

John, I have a very similar problem with a new computer I just built with an i7 hex core (5930K) and 16 gigs of DDR4 ram. I do have a GTX 970, but I am using GoPro recorded MP4 videos (1080/60). My preview lags so badly at even the lowest preview settings and lowered to 30 frames it is completely unusable. I have been stalking forums for a week and cant find any solution and am loosing my mind trying to make this work!

Well Nick perhaps this is dumb question, Do your files live on the same drive as your OS? I mean I have an old AMD Phenom Hex Core and edit cinema 4k 10 Bit 422 mov files. I won't tell you that it cuts like a hot knife through butter but it is workable and not near as horrific as others tell me but my media is on a different drive from my os and temp files.

I have Vegas on my SSD and and have tried putting the video files on there, on my 3tb storage drive, even straight from the SD Card (UCH class 3 on USB 3.0 hub/reader). They all perform equally despicably.

I found your thread after I posted this, of course...

You may have found your problem. I remember Vegas Pro having an awful time with some GoPro footage. You should use GoPro Studio to convert it to CineForm AVI files and your lagging problem should be fixed.

Yeah I'm sorry but the PC is barely adequate for the work. If use this you must then try lowering the preview resolution or create proxy files from inside Vegas.

You could of course download the trial of Vegas Pro. See if it helps the issue and determine if the software is the root of the problem, At least If you work fast you can finish the project before the demo runs out.
