so my clip is h264 MPEG4? how could you tell it’s H264? I only see MPEG4 and AVC…

also about my card, it does not support decoding of h264 because it’s too old correct? my only option is to install a new card then for hardware decoding , correct?

Hi, I can’t seem to be able to edit my message, I want to appologize for my spelling mistakes, please note a little close to the end of my post I said “so how do I tell if my player is actually doing hardware encoding or software encoding?” what I meant to say was “so how do I tell if my player is actually doing hardware decoding or software decoding?”, sorry again for the confusion…

Regards
Akram

Dave, Ok I guess I will keep it as it is then for now. thanks for taking the time to explain everything and help me 🙂 have a nice day!

Thanks Dave,

I tried MediaInfo and here is what it says about the file:
General Complete name : Prime 17.mpg Format : MPEG-PS File size : 2.15 GiB Duration : 1h 30mn Overall bit rate : 3 409 Kbps
Video ID : 224 (0xE0) Format : MPEG Video Format version : Version 2 Format profile : Main@Main Format settings, Matrix : Default Duration : 1h 30mn Bit rate mode : Variable Bit rate : 3 210 Kbps Nominal bit rate : 15.0 Mbps Width : 704 pixels Height : 576 pixels Display aspect ratio : 4/3 Frame rate : 25.000 fps Colorimetry : 4:2:0 Bits/(Pixel*Frame) : 0.317 Stream size : 2.03 GiB (94%)
Audio ID : 192 (0xC0) Format : MPEG Audio Format version : Version 1 Format profile : Layer 2 Duration : 1h 30mn Bit rate mode : Constant Bit rate : 64.0 Kbps Channel(s) : 1 channel Sampling rate : 48.0 KHz Resolution : 16 bits Video delay : -72ms Stream size : 41.4 MiB (2%)

So can you tell if it’s CBR or VBR? btw what does CBR and VBR stand for?

For the above file, do you think it’s possible to compress it without lousing a significant amount of quality? or is it better to just leave it as it is?

thanks!

Thanks again for you reply david, you asked if it’s CBR or VBR, I’m not sure, I recorded the file using a software called mfaraj dreambox viewer V3.0, this application uses a software module called wingrab to record from the dreambox 500 receiver. there is no options on the output, it always creates an MPEG2 file with a .mpg extension.

so I can use MediaInfo.exe to get more info on this video file? where do I get MediaInfo.exe? is it free?

thanks a lot for taking the time to answer my noob questions 🙂

David,

Thanks for your reply. I managed yesterday to find the option to make 1 video/audio ,mpg file, I think I used DVD_PAL_Lg or DVD_PAL_Sm not sure, I squeezed the 2.1GB but the result was a 5GB file! can you beleave that? even though the average bitrate in the squeeze settings was around 8-9 MB/sec. I’m really getting second thoughts now about squeeze, also I’m thinking it’s useless to try to compress an already compressed MPEG file. is 2.1GB file ok for a 1:30 hours video, with the above resolution and 15MB/sec bitrate? do you think there is a better solution than squeeze for compressing files on disk? I just want to keep a decent quality of my recordings, and have the possibility of moving them into DVD if I want at some point, while not using too much space on disk.

Also squeezing the file took a very long time, hours. is that normal for a file with this size? I have 2GB of ram, and an Intel Core 2 Duo 2.8Mhz E7400 CPU, and plenty of disk space, running 32-bit windows 7 build 7260.
