As a dual-core Tegra 2-powered speedster, it's no surprise that LG's Optimus 2X supports recording 1080p video. Despite having seemingly capable hardware, reports from people who have gotten some hand-on time with pre-release versions of the phone noted a less-than-impressive 1080p experience, with an inconsistent framerate and under-impressive clarity. LG has come up with a software update that address some of these issues, but there's still room for improvement.
When looking at an Optimus 2X running software V09C, GSM Arena noted several issue with 1080p performance. In their tests, the videos didn't quite make it to 24 fps, below which videos can start to look like a sped-up slide-show. They also found that excessive compression ended up resulting in videos that didn't look that much clearer than 720p, and found the phone duplicating frames just so it could keep up.
In the V10A software the retail release of the phone uses, there's some progress towards addressing these issues. LG has raised the data rate on 1080p recording, which should contribute to less noticeable compression artifacts, but it still doesn't appear as superior to 720p as it should be able to. The company also tackled the duped-frame issue, but the phone still isn't quite hitting that 24 fps mark like it should.
The Optimus 2X may not be able to compete with stand-alone HD camcorders, but the V10A software is a noticeable step towards making 1080p recording useful. Considering the progress already made, LG may be able to bump up performance even further with a future update.
