By any chance, do you have loop region checked? This image shows the loop region on the timeline (the area in the two yellow triangles): https://www.sonycreativesoftware.com/support/files/LoopRegionScreen.jpg so when you go to render as, if the loop region box is checked, it will only render that part of the video.
Maybe uncheck the “render loop region only” box in the render as window before rendering your video and see if that helps.

Hi,
“ If you started with GoPro Hero 4 AVC 2704×1520, 4:2:0, 60Mbps 8-bit 50fps Progressive, why do you want to go 4:2:2 and 50i???”
No I don’t want to do that. It was the DNxHD footage that was recorded in 10-bit 4:2:2 25fps interlaced 50i.
What I wanted to do take all the video clips, DNxHD videos and the Gopro footage and render them all so they both have the same settings (50fps progressive) and then render a high quality video with the clips, without any artefacts and other compression issues that could happen with the final video, but I realised there might be a better option.
After testing some renders, I figured the best option I have, might be to edit the DNxHD videos and render those back to the same DNxHD 10-bit 422 185mbps 25fps (50i) interlaced codec they were recorded in, and keep those, then all I have to do is take all my edited DNxHD video clips I want to use, import them along with the GoPro videos, which will now all be in 50fps Progressive, edit the GoPro videos and and render the final video to MainConcept AVC 1920×1080 50fps progressive 50Mbps for YouTube.
I haven’t really edited many videos in the past and this is my first tine working with interlaced footage and I can edit videos fine, but still getting to grips with rendering them right.

You didn’t shoot your interlaced footage at 50fps so trying to double the frame rate with Vegas Pro alone is going to be challenging and cause artifacts of some kind. Why not render to the lowest common denominator of 25 fps? That should look fine.
I wanted to convert it to 50fps as I noticed it was smoother than 25fps progressive. I have tried rendering 25fps progressive to 50fps and it doesn’t work well at all as your trying to double the amount of existing frames which doesn’t really make the video look any smoother.
But reading on wikipedia: “A PAL-based television set display, for example, scans 50 fields every second (25 odd and 25 even). The two sets of 25 fields work together to create a full frame every 1/25 of a second (or 25 frames per second), but with interlacing create a new half frame every 1/50 of a second (or 50 fields per second)”
So technically you have more frames to work with from the start since you have 50 half frames every second or 25 full frames, more than just 25 full frames as you’d get in 25fps progressive. I did a test render with my DnXHD 50i video by setting the project settings to frame rate: 50.00 (Double Pal), Field Order: Upper field, De-Interlace Method: Interpolate.
I then kept the smart sample checked in the video properties and the field order to upper field, and rendered my test video to MainConcept AVC 50.00fps, Progressive and after playing the rendered video back, it worked well and I got the smoothness with no issues. I just wondered if it could be done in Vegas, but to a 4:2:2 50fps Progressive codec without issues?
After checking my videos, the jerkiness I was seeing in some of them, was to do with having the wrong shutter speed set and the other issues like the pulsing, were in the video when I recorded it, so I am going to have to improve my shooting skills and get the video looking right before I edit a video that doesn’t look the best.

Hi John,
I am working on a project with MXF 422 8-bit video files and audio recorded at 96khz 24-bit as I mentioned here: https://forums.creativecow.net/readpost/24/979007 and would prefer to keep the 4:2:2 and the 96khz audio and not have to down sample anything.
I know AVI isn’t the best to render to, but it was the only render setting on Vegas I saw that allowed me to have both 422 sampling and 96khz audio (some other render settings can allow 422 but only 48khz auido max). If there was another way of having both, I would prefer it.

Hi Norman,
Thanks for the reply. Your right It wound’t really do any good rendering to 10-bit or better when the camera only outputs 8-bit as trying different render settings and codecs I didn’t see any difference in colors. I’ll keep playing around with settings and see what works best for me.
One of the issues I had wasn’t that I didn’t want to use avi entirely as it seems the best overall option. The problem I have when rendering an AVI is that when I do render a file to avi in different codecs like x264 or Cineform, Sony YUV etc… I can’t seem to get the rendered video to play back smoothly on any player like windows media player, VLC, Divx Player or media player classic without it either playing slowly and jerky, only getting audio and no video etc…
Anyone know how I could render to avi and still be able to play the video back smoothly after rendering?

Hi,
Thanks, tried the Options > Preferences > Editing tab and it worked fine for putting the still images on the timeline.
I found out if you select the first image in the timeline and change its pan/crop to how you want it, right click the image and press “copy”, then go to the last image in the timeline you want to have the same pan/crop and shift-click it to select all media before it and then right click (or it might be shift + right click) and press “paste event attributes” and that makes all the media have the same pan/crop.
Not sure if that works for adding other events as I haven’t tried that yet.

Hi John,
That would work great for what I want, thanks!

Hi Brand and John,
Thanks for the information. It worked great for what I wanted. Thanks for the video link Brad, helped with compsiting and sources as I knew it was something to do with that I had to change when I was doing this but wasn’t sure what.

I changed to the mp4 render and it seemed fine, crashed one but rendered fine second time, seem just WMV won’t render correctly as I said in my first message. Is there a way to get WMV to render correctly? I used it on Movie Studio 11 and it worked, just won’t on pro for some reason. I would use movie studio, but already made this project on pro and don’t think there is a way to import the project into movie studio.
Using MOV files recorded with Canon 600D 1080p HD if that helps.

Hi Steve,
No, but I’ll try that, I have rendered in this format before and had no problems.
