Bizarre issue with Sony Vegas 13
on Oct 30, 2014 at 3:13:53 pm

I am having a rather severe issue with Sony Vegas 13. I am trying to edit footage recorded using Bandicam NVENC. In order to do this, I had to install the x264vfw codecs, 32 bit and 64 bit versions, downloaded from here ( http://sourceforge.net/projects/x264vfw/files/ ), following this tutorial ( http://www.bandicam.com/support/tips/sony-vegas/ , the H.264 and PCM section). However, when it came to editing the footage, the video itself would not appear, I could only hear the audio. This was strange because when I first started the project, I could view the footage just fine.

Upon re-opening the project, the video track appeared blank, with 'media offline' written all over it, however the audio track was just fine. So I forced Vegas to forget the footage and I tried to add it again, however although the video was once again visible, the preview was horrendously laggy. I then created a video proxy of the footage, which seemed to solve all the problems: I was able to view and edit the video in Sony Vegas. However, now I have come to render the video, the problems have returned. The finished render ignored the main video track yet again, so I have a black screen project with audio but no video from the footage I recorded, and it is once again showing up blank on the timeline. I thought this was because Vegas was trying to render from the proxy, so I removed the proxy, and now I have a blank video track and a blank preview. What makes this even more bizarre is new projects using the same footage do not seem to have this problem!

My edited project, with the blank video problem: http://gyazo.com/6cc880c280d903037e3134dbf087f533
A new project, using the same footage, without the problem: http://gyazo.com/41379dfe0ef7505ff08c1335fadc8e6e

I am totally perplexed! I really don't want to have to go back and edit all the footage all over again, so is there any help you can offer me to help recover my edited project?

You don't want to edit footage that uses the x264vfw codecs for exactly the problems you are encountering. I would transcode the footage to MJPEG video and PCM audio using AviDemux 2.5 and replace all of your AVI files with the MJPEG footage. You shouldn't have to re-edit since they are both AVI files.

Ok, I'll give that a go but the reason why I recorded the footage with NVENC in the first place is because I wanted smaller file sizes, and the H.264 gives me just that. Motion JPEG file sizes are HUGE. In your opinion, will this issue with editing x264vfw occur every time, or just some of the time? If it occurs every time I'll have to grit my teeth and record in MJPEG anyway.

There are formats that are designed for editing, and formats that are designed for delivery. x264/DivX/Xvid are designed for delivery and are horrible for editing.

It will happen every time. Vegas Pro does not handle x264/DivX/Xvid editing well at all.

Editing video requires lots of hard drive space. That's just a fact that you can't get around.

Thanks, I'd better invest in another hard drive then.

You can never have too much hard drive space. ;-)

I use Western Digital Passport 1TB USB 3.0 drives. As long as your computer has USB 3.0 they are plenty fast enough for video editing and you now have unlimited space because when one fills up you just buy another. I always buy a few when they go on sale for $59 USD at various retailers.
