This is a complex topic. If you are doing your testes with FX’s on the video it becomes even more complex. Here’s why:
Rendering = Playback + Encoding
Since Vegas Pro 11, there has been playback GPU acceleration that is controlled under Options | Preferences | Video | GPU Acceleration. This is used for two things: (1) Playback of the media on the timeline, (2) GPU Acceleration of FX provided by Sony. This is based on OpenCL so video cards like the AMD Radeon HD and FirePro series will benefit greatly from this.
Each Encoder in Vegas Pro (i.e, Sony MXF, Sony AVC, MainConcept AVC, MainConcept MPEG2) may or may not support GPU acceleration of the encoder. Both Sony AVC and MainConcept AVC allow you to turn this on and off. Unlike the GPU acceleration for timeline playback, the encoders support both OpenCL and CUDA but only very old cards circa 2010. As you have pointed out, your GTX 960 is not supported.
To make things even more complicated, 3rd party FX like NeatVideo, Magic Bullet Looks, Boris BCC, have their own GPU support that is NOT turned off when you turn off GPU Acceleration under preferences and these plug-ins can and do use CUDA, OpenCL, OpenGL, etc. This is why we never add any FX when benchmarking render performance because this introduces too many variables.
I assume you have read my tests here on the COW in this thread here and here.
What I found was the same as you are seeing. Sony AVC is almost twice as fast as MainConcept AVC using CPU Only (i.e., no GPU acceleration of any kind) but that MainConcept AVC with a supported GPU was significantly faster than Sony AVC with a supported GPU by 3.6x!
It should be pointed out that since your GPU is not supported, and you are only using an Intel Core i5, you should expect to see very long render times and apparently… you are. If you want to improve render times, get an Intel Core i7 4 core or 6 core. It’s not only about clock speed. The Core i7 architecture is a lot better for video ending and rendering. So it is common to see long render times with a Core i5 and no GPU support.

[bill henry] “I checked the pan menu and nowhere is there a place to turn it off. It’s probably something simple. If anyone can help, I’d appreciate it!”
Actually it’s not that simple. You need to undo whatever it is that you did. If you created keyframes you should select all of them and delete them. The first keyframe is permanent and will not delete. This one will need to be reset. To do this, select the first keyframe, then right-click on the frame in the Pan/Crop window and select Restore from the popup menu. Close the window and you should see the square icon turn from green to grey again.

That’s good information Rob. If OBS is recording at a variable frame rate at times, it’s best to always transcode to a constant rate rate before editing in Vegas Pro.

Yea, glad you found that.
It’s extremely important that you don’t remove files from the camera card structure. Lots of people do this and it’s a really bad idea. You wouldn’t pull the tape of a miniDV cassette so don’t pull the video files out of a camera card structure. That structure is the cassette that protects the video and it’s meta-data about how to stitch it back together.
You should be copying the entire card structure to your hard drive for archival purpose. Then use the Vegas Pro import function to import the footage so that it gets stitched back together properly. In fact, I would keep a separate external drive that you archive all of your camera cards to. This is what I do. Then I can go back later and import the cards as needed.

[Aleksey Tarasov] “Turn on/off Snapping (press F8)”
Well waddaya’ know… dotted Marker lines means that snapping is turned off. I guess I never had a reason to turn it off. I learned something new today. 😉

[Aaron Star] “I would bypass vegas and get a copy of Handbrake.”
That’s not a bad idea. If you just want to do a straight conversion, Handbreak is probably an easier solution.

Maybe Oliver is referring to the fact that they are dotted lines and not solid? I’ve never seen that before.

[Mike Kujbida] “If you adjusted your monitor font size larger than 100%, set back to normal size.”
+1
Yea, setting your monitor DPI to anything other than 100% will mess up applications. This is a really poorly implemented feature in Windows. Always keep your display size at 100%.

[Amanda Duffield] “(f) All the mp4 options were greyed out. I couldn’t choose any of them.”
You have to make a custom template because Sony doesn’t have any good MP4 templates for PAL.
Here’s how:
- Select File | Render As…
- Make sure that “= Match Project Settings” is NOT checked
- Double-click on Sony AVC/MVC
- Select the template Memory Stick SD NTSC – 6256 Kbps
- Press the Customize Template… button
- Change the Frame size to: PAL 720×576
- Change the Template name to: Memory Stick SD PAL – 6256 Kbps
- Press the Save icon (diskette)
Now render with this template and see if it works as you had expected.

[jithendria kumar aravamudhan] “Is there a way to attach a title video to a bulk of other videos in Vegas?”
Vegas Pro Production Assistant was designed specifically for this kind of batch workflow. You can very easily set up a template with the title video and a slug to represent the video. Then point it at a bunch of videos and it will substitute your video for the slug and render in multiple formats, with each video you give it.
