the files recorded are big

[justaaq]

i have a question about the recording facility in the DVB dream
what controls the size of the recorded files (and is there a way to control it )
currently i have two extensions supported .mpg and .ts but they are both big
(1 min =30MB) and the resulted recording contains ugly lines that appear some times.
my Question is that is there a way to reduce the size or at least purify the recorded file ?
is it an option or should i download a plug in or something ?
and isnt there way to produce .avi files ?
sorry if my question sounded a little stu*** am new in this stuff
thanks in advance

For better underestanding your recording problem you should recognize expression "bitrate".

Some channels are broadcasting with bitrate 2500kbps (for example) and others with 3400kbps (f.ex.). The amount of bytes per second divide by 8 gives you space occuped on your hard disk per 1 second of record. The biger bitrate is - the larger file you obtain.

Avi file is a container - it connets video and some audio tracks (one or more) into one file. It is suplementation of MPEG-4 format . (Like matroska 'mkv'). You obtain it after manually compression with Virtual dub for example. (certain tv programs have an option to compress to avi 'on fly' - but you must understand that is comnsuming large system suplies).


DVB-S standard usually contains mpeg-2 format for video and mpa/ac3 for audio tracks. Extension 'TS' allows you to record every audio and subtitle track in whole stream (with video of course) - but then you have a larger file than in simple mpg extension.


For 'ugly lines' you should some read about interlacing - some direct show filters have an option to remove that lines (deinterlacing) and that is what you need to do for get rid of them .

To answer your question, no, you cannot control the recorded file size. File size can only be controlled when encoding (compressing) video. The video you receive is already encoded (mpg2). The only way to change its size is for you to re-encode it using a more efficient encoder (like h264). But that needs to be done after you have recorded it and it is a time consuming effort.

can you please be more specific ?
what did you mean by direct show filters?can you give me an example of such filters ?

thanks in advance
