Recorded size of files are double+ on cable compared to satellite recordings..ideas?

[ade1970]

not sure if anyone else noticed or if been asked before, but is there any reason why the recordings file sizes would be so different from satellite to cable recordings and in some cases the picture on the satellite is still sharper...hmm?? typically a 5gb file of approx 2 hours on satellite will be 10-12gb on cable!?
if so, wondering if there is a settings adjustment i've missed, or maybe the recording is recording 'extra' additional info in stream i could switch off perhaps?
thx in advance for any suggestions/ideas..

There is no way for you or any one else to adjust the size of a recording pre-record as it records the entire transport stream as broadcast, which includes every thing from subtitles to multiple languages in the one stream. Why there is such a huge difference between satellite and cable ?. I don't know as I have never used cable, unless your recording HD channels on cable and SD on satellite ?.

you can however edit the .ts files post-record to remove languages and subtitles etc if you intend to keep / archive the recordings for later.

It depends how the provider delivers the stream to their DVB systems.
Mostly cable providers have a stream with more bandwidth (less compression, more data).
A recording on my cable 45 min. HD gives me a 7Gb file.

I see broadcasts on HD channels with poor images.
It happens a lot that they put SD content in a HD channel.

Cheers for replies, kind of knew i hadn't missed something such as a setting, will definitely have a go at editing any extras, if indeed archive any of the files-definitely good to know as cable files are massive everywhere then and not just mine!..many thanks again gents

It's all down to the broadcaster. Bandwidth is limited in satellite but in the early days of HD it was possible to see streams of up to 20Gb per hour (BBC HD in Mpeg 2). The picture was way better than it is today. Mpeg 4 has much more compression and more loss but has acceptable file sizes.

All cable channels on the UK are mpeg2, you would think that mpeg2 should be sharper given that the bit rate and file size is higher but the AVC MPEG 4 codec is so efficient, I would go as close to saying it is amazing.

Wowza! Had no idea and now makes perfect sense! thanks for the responses..So pleased bought a very large hdd to handle these files , my old 500gb hdd would only have lasted a week at a time for recordings!

Well I've just bought a 2tb drive for my Solo4k, luckily I have nothing to record in 4k lol.
