Re: [mythtv-users] What's your recording file size?
As mentioned it is normal. You can adjust the data rate in the recording profiles. If you are recording analog from the air, then you might reduce the horizontal resolution from 720 pixels to 400 and reduce the datarate accordingly. And you can transcode to MPEG4 to reduce the data rate even further. But in that case you should better have a high rate in the MPEG2 to achieve a better MPEG4 result.Yeah, but I'm pretty sure the PVR-500 outputs MPEG-2, not MPEG-4, sothis kind of defeats the purpose of owning the PVR-500 (assuming hepurchased it with the MPEG-2 output in mind). Wouldn't it actually put *more* stress on the system to transcode the output from aPVR-500 card to MPEG-4 since the system has to decode the MPEG-2stream in addition to encoding the MPEG-4 stream? Of course the CPU and the harddisk will get more busy, but the CPU will only work on the transcoding when it has nothing else to do. I recordin MPEG2 (PVR-250) at 4.5 Mbit/s and transcode almost everything (except what I want in DVD-format) automatic to MPEG4 at 1.4 Mbit/s. So my recordings are initially at 2 GByte/hour, but after a while they areat 0.63 GByte/hour. I have a 1.6 GHz AMD processor and it does the work very nice. It can transcode almost as fast as record, so a couple hours after a movie has been recorded, it is already transcoded.

Ant.What do you mean by 'tuned'?If you are recording from a digital card, the bandwidth, and hence file size, is fixed as no processing isdone.It's not a matter of cleanliness.Btw, this is only as I understand things working, and that's only from using Myth ivtv. I am recording the analog signal from my digibox (as Sky don't have an offically recognised CAM this is the only way to deal with this, yes I know about Dragon CAM, see 'officially')So the input to my system is analog PVR-350 (I did mention it), the picture has better quality then terrestrial analog signals (less noise) and hence a cleaner signal. As the PVR card MPEG encoding has a dependancy on the consistency of data, a cleaner signal will allow for a lower sampling rate while still producing adequate picture quality.I 'tuned' (ok bad use of words considering frequency tuning) my encoding bitrates and the picture qualtity is as good as (to my human eye) the higher bit rates I was using. (There was a graph that someone found that showed the different bitrates of various media). I believe that I can make further improvements with either bitrates, or capture size, but I have to wait for my widescreen TV to come back from repair so I can see the differences, (the little portable I'm using at the moment just wouldn't show it). Hope this helps explain my previous post. If I've missunderstood something let me know, as it might help me do an even better job.Ant. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
