I wonder if there is a possibility to make delay saving a little different. On my PC it takes about 25-40 seconds to save 10-second piece of 720p video delay to SSD. The worst thing is, the delay capture is "freezed" during saving. I think it's worth to improve the process.

I guess the procedure for saving video now is:
1. user clicks [save]
2. vMix pauses delay capture
3. vMix renders video file and saves it (the longest part)
4. vMix starts capturing delay again

What if between 2 and 3 vMix could:
- create a copy of delayed uncompressed video, store it in RAM
- restart video delay capture
- then render the video file from the copy?
- delete the copy of uncompressed video (from RAM)

Wouldn't this be better? This solution is not ideal, for sure it needs more RAM (sometimes event twice), so I think it's good for 64 bit systems only. A guess this way of saving delay could be an option to choose.

Or maybe the process of duplication the uncompressed video in RAM will take too much time and resource?

Any thoughts?

What CPU do you have and what compression have you selected for the video delay?

It should save faster than real time on a suitable CPU and with a good compressor such as the CineForm codec or DeckLink MJPEG.

The DV Encoder is quite slow.
I would suggest using DeckLink MJPEG Compressor if you have it or download GoPro CineForm Studio.
