Encoding DVD in real time from DigitalBeta
on Mar 28, 2011 at 2:45:38 pm

Hi, I would like to build up a PC for encoding DVD from DigitalBetacam (NTSC/PAL). I want the quality like to be most retailed DVD. However, I am short of budget, so, which capture card should I choose?

See if you can find someone selling a used Zapex encoder board. Be aware that the company went out of business years ago, so you want at least the board and the software. Better would be a working PC with the board already set-up.

Thx for reply!
However, are there any capture cards that have DVD encoding function??
Like Black Magic, Canopus?

Canopus might have an encoder board similar to Zapex. There is also the Sonic Solutions encoders. Using a Black Magic or Aja capture card requires software encoding after capture.

Thx!
I've checked Canopus, and find out FIRECODER Blu. IS the quality Okay for retailed DVD?
And what is the minimum requirement of the PC for DVD encoding?

[Siu Kei Ip] "And what is the minimum requirement of the PC for DVD encoding?"

The manufacturer of the encoder board will have specific requirements for the PC for its products. In general, you want a workstation PC (not an "office" PC) for its segmented PCI bus. You need a faster (and big) second hard drive to store the media. DVD encoding does not require a RAID.

You should demo the encoder you are considering using familiar footage to see whether you like the results.

Actually, if I decide to buy a capture card and use software encoder for DVD/Blu-ray production, will I get worse quality than hardware realtime encoding?

Most encoders are software based these days. Cinemcraft SP is about the finest encoder around unless youre prepared to hand over thousands of dollars

Slu,

I have an old Sonic Solution SD2000 card and a computer that can run it. My version for a Mac and it only runs on OS9. I can sell a turnkey system so it really doesn't matter what system is it. This card has reverse telecine and segment based recoding.

The only advantage of any hardware encoder card is if you are coming from a tape (which is what you said you where doing) You don't capture and then encode it all happens in one step. But the card is only for encoding for DVD authoring.

If you are interested contact me at onthecow (at) michaelangelodv (dot) com.

Once again Hardware encoder does not give you better than software but it gives you professional quality at real time from tape masters. I will let this go cheap, I just need to replace the computer with any intel mac, a used iMac intel would be fine.

The Matrox MXO2 Mini offers realtime MPEG-2 capture straight to .m2v and .wav from Composite, S-video and Component sources, with RCA stereo audio input.

I haven't messed with this new feature enough to comment on how good the quality is using the realtime capture to MPEG-2 though. Probably not on par with a high-end specialty encoder

@ Jeff, at you sure that is a DVD compliant stream. Nothing on their website mentions the ability to go to a DVD stream. There are a lot of variations of mpeg2 but only a specific one can be used with DVDs.

Hi Michael,

Matrox MXO2 Mini absolutely supports direct capture to "MPEG-2 for DVD", saving directly to .m2v and .wav files compatible with Adobe Encore.

I checked the website and you're right, they don't seem to be advertising it, but the feature is most definitely in the software, and in the manual. Older Matrox hardware also had the capture to MPEG-2 for DVD option as well.

But again, I haven't done any thorough testing of the quality of the realtime MPEG-2 compression compared to doing it through Adobe Media Encoder for instance

Is that capture card only compatible with Adobe Encore??
