PS - Avoid Variable Bit Rate if you can, in favor of Constant Bit Rate (VBR versus CBR). Last: As an alternative to the free Handbrake program there are other conversion programs around (Bigasoft, WinX, Telestream) which do a good job and result in smaller files. If you're not mastering to a DVD, reduce the audio from 48kHz to 44.1kHz (a very minimal loss that is usually almost unnoticeable if you're not playing from a DVD). Or - if the source files are 4k video - you could easily reduce to 1080p or even SD (720). When converting, instead of altering the parameters you could convert the source files into 2-4GB chunks (see above note re camera recordings).

if the source *.mxf files are smaller than the Handbrake output, it's a good bet that Handbrake is not doing anything to add quality to the video (you can't add information where there was none) so my first thought would be to adjust the conversion settings to reduce file sizes. Basically, they place a burden on the computer's resources - even a powerful computer with a fast chip & sufficient RAM (and even with a solid state drive).Ī 9GB source file is pretty hefty - in fact, most broadcast cameras cap the file size at just under 4GB but seamlessly continue onto a new 2GB file as the camera continues to record, resulting in a series of 14-minute files. Large source files can be a problem for any video editing program, even ones like Vegas Pro which use proxies instead of copying entire files into memory.
