Compression & Media Summary
• The camcorder uses AVCHD to compress video, but the 1080/50p mode uses an original MPEG-4 format.
• There is no internal memory on the camcorder (it records to SD/SDHC/SDXC cards only).
• The editing software that comes with the camcorder allows you to import 1080/50p clips as well as 3D footage and regular video recordings.
Compression (9.0)
The Panasonic HDC-SDT750 uses AVCHD compression just like most consumer camcorders that record HD video. However, since AVCHD can't handle 1080/50p, the camcorder also makes use of an "original format" MPEG-4 compression system for recording footage in the 50p mode. This is the samesystem that was employed on the Panasonic HDC-TM700. Read more about the advantages and disadvantages of AVCHD.
3D files are recorded as regular AVCHD clips on the HDC-SDT750, so there's nothing different about importing them to a computer. If you view the clips on a regular (non-3D) HDTV, though, you'll see two images on the screen split down the middle. This is also what you'll see if you import the 3D clips to an editing program.
| Format | Resolution | Bitrate | Codec |
| 1080/50p | 1920 x 1080 | 28Mbps | MPEG-4 (original format) |
| HA | 1920 x 1080 | 17Mbps | AVCHD |
| HG | 1920 x 1080 | 13Mbps | ACHD |
| HX | 1920 x 1080 | 9Mbps | ACHD |
| HE | 1440 x 1080 | 5Mbps | ACHD |
Media (5.25)
The HDC-SDT750 is a card-only flash memory camcorder, which means it has no internal memory for storing video or photos. Leaving out internal memory helps keep the cost of the SDT750 down, but it also means you must purchase an SD/SDHC/SDXC memory card before you can start recording video with the camcorder. Read more about the advantages and disadvantages of flash memory.

The recording times vary on the HDC-SDT750 depending on what quality setting you use. The 1080/50p mode is the highest quality setting (it records at the highest bitrate), so it allows for the shortest record times. There are other versions of the HDC-SDT750 available in Japan that do include internal memory (like the HDC-TM750), but those models are not available in the US.

Editing (7.0)
The Panasonic HDC-SDT750 ships with HD Writer AE version 2.6—the same software that comes with the Panasonic HDC-TM700 (and HDC-HS700). The software enables you to import video, including 1080/50p clips that some editing programs may not be able to handle. For an overview of the software that ships with the Panasonic HDC-SDT750 and other Panasonic camcorders, see our article: "Video Editing Software For Your Camcorder"
3D clips can be imported using the provided software and the clips are also compatible with most editing programs (any editing program that is compatible with AVCHD). When you import them, however, the clip will display two distorted images side-by-side. When viewed on a 3D TV, these images will overlap to create the 3D effect.
