Jittery Playback and Slow Running
I have a problem in that I bought a laptop specifically to use for video editing with HitFilm Express, but I didn’t really acknowledge the fact that the graphics card was the bare minimum spec to be able to handle HitFilm. I’m now some way into the project and the software is generally running slowly, not only when trying to playback sections which I’m editing Intermittently jittery) but also when trying to move around the project workflow. Is there any way to be able to play back the edited footage smoothly without having to resort to either upgrading the graphics card or buying a new machine altogether? The spec and context of my situation is as follows: I am running an Asus N55S with an Intel Core i7 2670QM processor @ 2.2GHz, and an Nvidia Geoforce GT55M graphics card (I have just updated the driver for this). The graphics card was unable to handle the raw 1,920×1,080 HD footage at all so I have been down-scaling it all to 1,280×720.
Whilst the project is a sci-fi production, it’s not especially heavy on effects; it’s mostly a mix of basic editing, some motion tracking, a few lighting effects, masks, etc. and a couple of more sophisticated effects using some of the default CGI elements. I’ve also created a title and credit sequence with text captions and it’s been especially struggling with playing back these.
I've recently cleaned up the hard drive (not that it was in any way clogged up) and I have 150GB of free space.
I'm not so worried about slow processing per se, just that I want to be able to play back what I'm editing smoothly.
I have found this plug-in device which appears to allow smooth HD playback via an external monitor but I’m assuming my inadequate internal graphics card would still hinder playback?
Any advice would be greatly appreciated.
