The JVC JY-HD10 (and the GR-HD1) both come with a bundled software.
Included is the MPEG Edit Pro LE 1.2 which is feaure-reduced version of KDDI's (of Japan)$4,800 MPEG Edit Pro. It is not an easy program to use but once you get the hang of it. It is very, very powerful Non Linear Editing (NLE) software.
Just like DVD's HD is also an MPEG stream but the camcorder’s HDV acquisition format presents some unique problems for post-production.
DVDs use MPEG-2-encoded video that has been encapsulated into a program stream. A program stream is generated from one (or more) audio plus one (or more) video elementary streams.
An audio elementary stream for a DVD can be 16-bit, 48kHz PCM; AC-3 (Dolby Digital); or DTS Surround Sound. A DVD can have one or more types of soundtracks. Of course, it can also have multiple audio tracks as on a multilingual DVD. A DVD's video elementary stream is encoded as MPEG-2. If the DVD offers multiple angles, each angle is a unique MPEG-2 stream.
A program stream generator takes elementary streams and weaves them together in a single stream. Once this stream is assembled, it can be burned to a DVD. To play back a DVD, software or hardware examines the data stream to find the audio and video streams. A header identifies every stream's type.
Now, here is where the HD differs from DVD.
The HDV format has two elementary streams. The total data bandwidth is 19Mbps for 720p and 25Mbps for 1080i. A camcorder's 16-bit, 48kHz audio is encoded as MPEG-1, Layer 2. The stereo channels have a combined data rate of 384kbps. On disk, this type of stream should have an .mp2 file extension. Video is encoded, of course, using MPEG-2. More specifically, for both SD (480p) and HD (720p), JVC's HD10 uses a closed, IBBP, six-frame GOP. The video data rate is 17.8Mbps using constant bit rate (CBR) encoding. On disk, it should have an .m2v file extension.
These two elementary streams are woven into a single stream. For HDV, however, the stream is a transport stream — not a program stream. Simply put, a transport stream carries additional information that enables its cargo of video and audio data to withstand corrupting transmission conditions. On disk, this type of stream should have a .m2t file extension, but typically will have an .mpg extension.
The software and hardware that process a program stream cannot process a transport stream. This is the crux of the difficulty in playing, editing, and generating HDV.This is why ordinary MPEG-2 software on your computer can not handle a transport stream.
To edit HDV material, a transport stream must be “demuxed” into audio and video elementary streams. This can be accomplished using a separate utility — or the capability could be built into an NLE. NLEs that can accept a transport stream include MPEG Edit Studio Pro 1.2 LE and Vegas 4.0. While neither Adobe Premiere 6.5 nor Premiere Pro can import MPEG-2 transport streams, they can import Wavelet-compressed files from Aspect HD.
MPEG Edit Studio Pro 1.2 LE supports two A/V tracks. Each track has a video and channel. Imported HDV clips fill both channels in a track. Simple transitions (dissolves and wipes) can be placed between video channels. Video inserts into a channel can also be performed. Simple titles can be placed in a video channel as well.
