New HD's, MPEG-4, and disk space

[40-Dan]

Does anyone know how many hours of HD in MPEG-4 can be recorded? I know that the previous HD channels in MPEG-2 ate up a lot of space.

Approximately 50 hours of MPEG4.

30 hours MPEG2
50 hours MPEG4
200 hours SD

[Stuart Sweet]

Of course all of Scott's information would be exclusive, you can record 30 MPEG2 or 50 MPEG4 or 200 SD.

[Michael D'Angelo]

I have been doing some testing with only MPEG4 HD lately and it looks like it may only be a little less than 40 hours.

Right now I have 10 hours of MPEG4 and only have only 74% available.

But I am going to keep all of my MPEG4 recording's until the hard drive is full and see what I get.

Once compression is involved there is a factor that depends on the content of the video stream. With MPEG4 it also depends on the motion in the video. That is, more motion will mean more bits. I don't know how they came up with 50, but I'm sure it's just a guideline or average.

The are "estimated" recording values, based on one particular compression/bitrate.

So for MPEG-4

You could get anywhere between 40 and 60... or even more or less, totally dependent on the content.

[kevinturcotte]

Like the others said, depends on what you're recording. Recording only your nightly 11 news, you'll probably get 60 or so hours. You start recording action movies, and you're more likely to get 35-40 hours.

Get a Seagate 750GB and allow yourself some freedom.

Sorry if this has been addressed elsewhere, but does the MPEG 2/4 distinction have any relationship to the use of two different colors in the blue horizontal bar that shows percent of disk capacity used?

Just that 4 will take up less memory than 2 if that's what you're asking.

To clarify, recently I've noticed that the bar that indicates capacity sometimes has a darker component at the far left and then a lighter component, which together represent used capacity, and then to the right of those is the portion that represents unused capacity. The two components of the used capacity bar apparently represent different things but I'm not sure what those things are.

Do they represent MPEG 2 and MPEG 4 content respectively? Or maybe broadcast and DOD content?

The darker bar on the far left represents those recordings you have marked as "keep until I delete". The lighter blue is all other recordings.
