Reducing size of my mpg files

Total newbie here... :confused:

I've been happily using VideoRedo Plus (v3.10.3.609) for a few months now; I use it exclusively for processing mpg files created by my TV Card (Nebula DigiTV PCI). [The output files always need 'repairing' in order to work properly for some reason (someone recommended VideoReDo to me for this purpose), and I also remove commercials at the same time.]

My only problem as such is that the saved files seem (at least to me) very large - roughly 1Gb/hour - so fill my hard disk pretty quickly. They are comparable size to the original unrepaired files.

Is it possible to get VideoReDo to reduce the file size when I save them, without significant loss of quality? It's not as if these files are HD quality; and for example I've watched AVIs from other sources on my system here, at only about 300Mb/hour, with not much difference in quality to my own mpgs.

I've trawled through all the help files etc, but can't find what I need (sorry I'm not at all clued up on video editing. But I'm guessing 'bitrate' is the key parameter here?)

Many thanks for any help

If you'll load one of your videos into VRD and type: Ctr-L
it'll give you the specs of the video you are dealing with.
Alternately, you could download the free utility, MediaInfo and get similar specs from it.

Include that info in your next post.
When we know what you're working with, I'm sure someone will be able to offer a reasonable solution.
And remember, this IS a holiday weekend, with many people taking Monday off, too. ;)

I take it you are in the UK?
Is this terrestrial broadcast, or satellite, or... ?

Thanks very much for the response. OK, so in answer to your queries; yes I am indeed in the UK and the recordings in question are all terrestrial digital broadcasts.

Here are the specs of a video I've recorded (FYI this is the native 'unprocessed' version, although the specs are the same when I've run it through VRD):

File Name: G:\My Documents\TV\DigiTV recordings\Rev.mpg
File Size: 732154077 ( 0.68 GB )
Program Duration: 00:31:34.05
File Type: PS - MPEG2
Encoding: MPEG2
Video stream Id: xE0
Encoding Dimensions: 720 x 576
Display Size: 720 x 576
Aspect Ratio: 16:9
Frame Rate: 25.00 FPS
Bit Rate: 8.000 Mbps
VBV_Buffer: 224 KB
Profile: Main@Main
Progressive: Prog or Int
Chroma: 4:2:0
Audio Format: Layer 2
Audio Stream Id: xC0
Audio Bit Rate: 256 Kbps
Audio Sampling Rate: 48000 Hz
TS Mux Rate (bps): -1

Any advice on how to proceed would be much appreciated...

Happy New Year!

Yes but you will need to upgrade to V4, this has H264 capability which compresses the file. H264 can compress 40-50% very easily and sometimes more depending on the amount of action in the video by selection the bitrate. Also VRD does not support AVI.

Thanks. Is this really the only way forward for me? I really hadn't wanted to have to buy more software. Looking at the file specs I posted earlier, is it possible to tell whether there is reasonable scope for filesize shrinkage there?

Alternatively, might it be feasible to save the original files 'smaller' (ie what parameters would need adjusting?), and get round it that way for future files? (I'm using Nebula DigiTV 3.5)

To have have frame-accurate editing and compression with ''not much difference in quality'' [your quotes] then only VRD will do the job. The upgrade only costs $25 US. There are lots of enhancements in V4, well worth the price. If $25 is tooooo much for you then have a look at x264.

Sure the only other way with what you currently have is to recode to a lower bitrate. The side effect is that the quality with be diminished greatly. But then you just negated the your one requirement ''not much difference in quality''.

He mentioned he has Plus. The upgrade is a bit more.

The upgrade from VideoReDo Plus V2/V3 to V4 is $46.99 and is available here:

I recently downloaded one of my favorite television shows using my Nokia android phone..The size of each episode was clearly indicated i.e( Grimm episode one -100mbs) ..I normally download files with less mbs so that i can save on space, upon downloading a few episodes i was shocked to learn that each episode carried 250mbs, i used another phone and it gave me different results ..It took the 100mbs as should..could there have been a file conversion problem with my original phone?
