Advice on storage of MPEG2 video for future use.

[adamp007]

Hi,
I am in the process of capturing all of my analogue video via a MIRO DC30. I was going to edit and then output as MPEG2 at the Highest Screen Res for PAL (ie 720x576) at a constant 9Mbits per second to ensure the least loss. Since the MPEG2 is a standard and i may not have the Miroi board in the future, it seems the best way for me to store.(the thought of storing 160gigs of AVI file on CD fills me with some dread)

Would there be much loss if say in the future the MPEG2 file was transcoded to say 6Mbits/sec. Would I be better of coding in say 6Mbits/sec VBR at the first outset rather than the larger bitrate.

Any advice would be most appreciated. What have other people done?

Thanks
Adam

Can no-one at all give me some advice?

Hi, I’m not an expert in this area but I’m trying something similar.

My experience, first of all is that the file should be saved with the bitrate of 8Meg/s as this seems to be some sort of standards for DVD and therefore minimize any compatible issue for future use (I have hade this problem both at higher and lower speeds with MPEG2, but 8 Mbit seems to always work).

Secondly, beware and this is my main problem. If I trying edit/convert/save my MPEG2 original to any other format the result is relay bad (less that VCD quality), (see my post
“MPEG2 conversion/Quality loss”). So any guidance/testing or opinion is appreciated!

Lastly a question to you, when you capture your AVI file don’t you run in to the 2G file limitation in windows?

What is your source? VHS? If so, then you don't need to go DVD with that resolution/bitrate. It is a waste of space/time...
For VHS/SVHS the best solution is CVD. Mpeg 2 with D2 resolution and bitrate with an average of 2400 for TOP quality results.
For DV source you have to choose between CVD (20% picture loss) or XSVCD (SVCD with bigger resolution/bitrate)
