Beta SP????

[Videobiker]

I would think it would depend on what your final delivery has to be. I do alot of TV work and have to deliver on Digi beta, but to take things in at 10 bit becomes unrealistic with the amount of tape I have to load. I take things in at 8bit to US DV 48 do my edit and then recapture my final cut at 10 bit for output.

I would take it all in at DV if you don’t have to finish at 10 bit and if you do just recapture your finished cut at 10 bit.

[nick Franco] “if beta sp is only equivilant to mini DV then maybe i should just capture it at Mini DV. is there any point capturing at 10bit uncompressed?”

Nick,

First, BetaSP and DV are not equivalent. They operate in entirely color space. As VideoBiker said, your decision depends on your final destination, but typically a decision like this is based upon the desire to keep the graphics at high quality, which dictates working in either 8 or 10-bit uncompressed.
8-bit should be absolutely fine for most needs…

Well, they are very equivalent in overall quality, but it’s a mistake to take one highly compressed format and convert it to another highly compressed format (if you’re concerned about image quality) as you’re just going to get the worst of both worlds, analogue compression mixed with digital compression. That said, depending on what the end result is, and how critical it will be looked at, it may make no practical significant difference to the output.

Analog compression? Please explain.

[Rick Diamond] “Analog compression? Please explain.”

Rick,

I think what Graeme is referring to is BetaSP in-camera compression. BetaSP is an analog format, so its “on the fly” in-camera hardware compression is analog and recorded analog to tape as well.

Hi Guys thanks for all your coments. i should have explained more in the first instance.
basicaly the end product may go to broadcast, but right now i have to compress for the web/ wmv and H264 or what ever works best for my client. i’ll probably use episod pro.

i understand that analoge works in a diferent way and mini DV has a digital compression with a 4:2:0 color space (uk Pal) and Beta sp i’m not sure about
i was thinking long term and meeting my clients needs in the next few weeks (they will keep changing their minds)

therefor i want to captur the Beta SP footage in a reasonable format that will:

A. allow me the greatest amount of information so i can downconvert for the web at good quality
B. allow me to out put at the same quality i’ve recieved it in (or near enough)
c. avoid having to recapture in a week or twos time for broad cast.
d. get the maximum quality for a reasonable file size

i was thinking i might be able to get away with DV 50 or 25 or even DV at the end of the day it has to be digitized. 8 bit uncompressed is fine too, but if the format i’m capturing from is being upconverted then is that really nessaccery.

however if i capture at 10bit uncompressed would i be right in thinking 4:4:4 coulour space? then if i downconvert to say a H264 codec i would get a better result as opposed to if i just captured mini DV

there are so many codecs out there that i do get confused.

they say a little knowledge is dangerouse. i know enough to now when i need help and you guys are being a real help. sorry if i’m missing something but it’s late here in the uk and it’s been a long day

thanks to you all

thanks dave and all

that has settled it for me 8 bit it is

thanks again

Hi Nick,
I completely agreed with David and Graeme. That BetaSP is more or less the same than DV is truth if we talk about image quality but they are two different worlgs. As Graeme says BEtaSP is a compressed format. Although has been for many years the proffesinal video standard, and many people call him Broadcast, BetaSP never has been a Broadcast format because it doesn’t reach the “Band-width” and the “Signal to Noise ration” that a Broadcast system has to acomplish. If I should capture some BetaSP footage I would do it as well in 10/8b Unc. And if I would be too contrained by the files size I would do it in DV50 that at least is a 422 format. Never in DV.
Cheers,
Rafael

Well broadcast is whatever is broadcasted, I (grand daddy) remember that u-matic was broadcast, at Sundance I saw Films that where shot by mobile phones, so ?.

judge if it’s good for you, then it’s good enough for your friends and the rest of your world

[rafalaos] “BetaSP never has been a Broadcast format because it doesn’t reach the “Band-width” and the “Signal to Noise ration” that a Broadcast system has to acomplish.”

What????

Sorry Rafael, but this statement is just WRONG!. Beta SP has been the standard “go to format” for many years before digibeta was invented. News. Documentaries. Network playback. All of it was based on beta SP. Sure new formats were developed, but to claim Beta Sp was not “broadcast format” is just misinformed. Please be careful when making such sweeping statements. It calls into question everything else you may claim.
