Is mpeg capture in MMC (mp2) same as normal MPEG2 file?

[Emanef]

I read somewhere that the mpeg files captured in Ati's MMC are not normal MPEG files. Is this correct? They have the extension mp2, which I don't recall seeing before I got my All in Wonder card.

Thanks.

yea mp2 is ATI's dumb extension for MPEG-2 files

they are MPEG-2 files but not SVCD standard MPEG-2 files

but they are NORMAL mpeg-2's :-)

Sorry, but what do you mean by this? I've tried opening one in VirtualDub and it says invalid file format, and when I try to select one in Tmpgenc it allows me to select the mp2 file, start checking the file then the programs closes.

I can get VDub to capture, so at the moment MMC is my only option.....

Ok

SVCD is mpeg-2 but not all mpeg-2 files are SVCD (it's just a specific format)

VirtualDub will not open any mpeg-2
TMPGEnc will open mpeg-2 files if you have an mpeg-2 codec

you can get VirtualDub to capture if you install the WDM wrapper- not sure where the link is - or if you updgade to MMC 7.6 you can use any codec you want (AVI)

why not capture at MPEG-1 with a higher bitrate until you figure this stuff out

I tried installing 7.6 but the tuner wouldn't work (I uninstalled everything, etc as you're supposed to) so I rolled back to the 7.5.

I can't currently get VirtualDub to capture the picture, just audio (I've already posted this prob but haven't had a reply yet!)

Perhaps this is due to the WDM Wrapper - what is this, and where can I get it? I also have to retune the tuner and reselect all the options everytime I restart VDub - is that correct? First time for years I've seen a program that doesn't save settings!

I've just set it muliplexing a mp2 file in Tmpgenc so that may work, though, even if it works, I don't want to have to keep using this method, as it's taken 10 minutes and showing 11 left on a 2gb/45 min file!

Thanks.

yes you need the WDM wrapper - search this forum

your doing something wrong - 2 gig for a 45 minute file is not right - you need to do some more research and maybe say what your goal is (making VCD's? making SVCD's?)

why not try MPEG-1 ???? it's not that much different -- then get used to editing / frameserving / converting ....

OK, this is my ultimate goal.....

At the moment I'm having to capture to a 5400rpm ATA100 hard drive (not the one my OS runs from, which is a 7200). This drive is usually for storage, but since getting the AIW7500 I've been trying capturing at differant settings to try to get an idea of what my system is capable of. I am getting another hard drive, probably 80Gb ATA100 7200rpm in a few weeks, which will be solely for video, so until then my system is pretty restricted (the 5400 also only has a 512k buffer!)

I eventually intend getting a dvd burner (prolly in about 6 months when they're below £200), and want to be able to capture movies from the telly (via composite ins, not tuner) to store/burn onto DVDr, prolly aiming for 1 per disk, so 1.5 to 2 hours per dvd, at the best quality available to fit into that size.

Until then, I will burn the odd SVCD, which I understand fits around 30 mins onto a cd. Until I get a DVD burner, I also intend getting a VideoSender unit, so I can 'send' movies captured onto the hard drive to my TV/amp downstairs (see the masterplan?!) from the video out for the second display.

So, for now I want to be able to capture as high a quality as possible at SVCD & DVD/XVCD (I think!)

I keep trying with different resolutions/bit rates/ frame types/ motion types but can't work out the difference between each! Sometimes I get really good results and someties really bad, but when I keep settings I think I need, they don't affect it!
