Issues with uncompressed video in edting software I want to create a video from a collection of sequences I took with a light portable camera in 1080p. Because the sequences are quite shaky I used VirtualDub/Deshaker to process the video files and stabilize them. The output from VirtualDub was saved in uncompressed AVI (around 10GB per minute). I thought that it would be better to continue in raw in the video editing software and then to re-compress only once the end result is ready to export.

The problem is that video editing software tools seem to have a lot of trouble playing back my uncompressed video sequences. I tried Movie Maker without success and then thought a more pro tool such as Lightworks would be better. However both tools struggle playing back the video. The PC I use is a high end i7 desktop with 16GB ram but it looks like the bottleneck here is the hard drive.

Is there a better way of keeping the quality of the video between VirtualDub and the editing software, perhaps a lossless video codec ? Or is there something I'm doing wrong here ?

Thanks.
The limitation is certainly the disk I/O, which at 10GB/min is outside the capabilities of all but very high-end disk subsystems. 

It's generally true that you should work at the highest bit rate and bit depth your system is capable of so you have the headroom for processing, but your system simply isn't capable of working at the rates your asking of it.

Determine what you need as the end result and pick a reasonable level above that for editorial. Uncompressed 1080p is way overkill if your target is YouTube, for example. Usually, choose an all I-frame (no interframe compression) format and a bit rate that will allow your system to handle two or three streams at once. If your disks can handle 60MBytes/s random access, it can play 3 80Mbit/s sources for compositing, and so on. That's more than needed for all but the most demanding targets.
