I'm not completely sure what's going on here but let me visualize my problem through videos.

Here's is what my Preview window shows.

And this is what Sony Vegas Pro 13 renders into an .mp4 720p60FPS.

So as you can see, Sony Vegas Pro 13 seems to be skipping a few frames throughout my video, but it only seems to do it where I have very heavy edits as you can notice in the final render.

I am using plugins from Sapphire Genarts OFX, Red Giant Link's Magic Bullet Looks, Boris FX Plugins, and build-in plugins from Sony Vegas Pro 13 itself, is it because there is any incompatibility between the plugins, or is this a bug in the program itself, or should I change anything in my projectsettings, etc?

FYI I have rendered this in 3 possible ways; .avi .mp4 and .avc but so far all 3 of them give me the same result but on different frames throughout the video, but still on the heavily edited parts only.

  • What's the frame rate in your project settings? And in your render? 59. 94 or 60?

  • @Mulvya My project template is 1280x720p 30FPS and my render is 1280x720 59,940 FPS. Feb 16, 2017 at 12:36
  • I just noticed that if I put my project to 59,940, or 60FPS, it seems to be stuck on those exact frames as in my render, anything I can do about it? Feb 16, 2017 at 12:37
  • Can you render a small portion surrounding these frames as an image sequence and check?

  • @Mulvya I still get the same result. Feb 17, 2017 at 16:17

I know this reply is 4 years past, but hopefully its of some use to someone. But I found that matching your project/raw files to match your output fixes that issue for me personally, so if I have a 1080p30fps raw file, the final render needs so also match 1080p30fps, if you "upscale" to 60 fps, you'll have ungodly render times and paused/skipped frames.
