Some tips if you are using the Sanyo Xacti VPC HD1010 camcorder supplied with the ISDS usability kits.
The HD1010 supports video recording in any of eight formats, shown in Table 1. A frame rate of 60 fps is actually saved as 59.94 fps. A frame rate of 30 fps is actually saved as 29.97 fps.
| Name | Resolution (pixels) | Frame Rate (fps) | Note |
|---|---|---|---|
| Full-HD | 1920 × 1080 | 60 | |
| Full-SHQ | 1920 × 1080 | 30 | |
| HD-HR | 1280 × 720 | 60 | |
| HD-SHQ | 1280 × 720 | 30 | |
| TV-HR | 640 × 480 | 60 | |
| TV-SHQ | 640 × 480 | 30 | |
| Web-SHR | 448 × 336 | 300 | no audio |
| Web-SHQ | 320 × 240 | 30 |
For the purpose of external recording for usability testing, 30 frames per second is sufficient. I suggest you record in HD-SHQ mode (1280 × 720, 30 fps). Film a test clip and check that your video editing software can handle it. If you want to film in HD, use Full-SHQ mode (1920 × 1080, 30 fps), film a test clip, and check that your video editing software can handle it.
Videos are saved in MPEG-4 format as files with the extension
.MP4. Pressing the red Rec button starts a
new file, pressing Rec again stops recording and closes the file.
The files are automatically numbered in sequence by the camera.
A longer recording is saved in segments of 4 GB each.
