So where could I find and buy a capture card that is compatible with the PS3? Or are they all the same pretty much?
Can you recommend any that are good?
And which ones do you guys here use?
You have two main options High Definition or Standard Definition capture cards.
As far as I know, if you have a SD capture card, your PS3 must be connected in standard definition (not too much of an issue if its simply recording replays i guess - but for live gameplay recording or other games be aware you need to play via the component cable).
Options (I know of) for HD: Hauppage PVR and Black Magic Intensity PRO
SD: Dazzle DVD Recorder (you need to buy some additional splitters which are really cheap on amazon).
Quality wise (opinion), the Hauppage HDPVR is best, closely followed by Black Magic, the Dazzle is reasonable and adequate for most purposes. You can also go on YouTube and insert the capture card device name followed by "Quality Test" to see which ones would meet your requirement (on the HDPVRs make sure you view in 720p or 1080p!)
Cost wise this is reflected as above, you will be looking to spend the good part of £200 for the Hauppage, £150 for the Black Magic, and £40 for the Dazzle.
Also bear in mind, if you wish to upload the video files onto the internet, then since the HD files will be greater in file size than SD, they will take longer to render. I don't know how large the file sizes will be so cannot comment further on this, but you may wish to consider your upload speed as well.
I was considering getting the Black Magic, but then thought I'd try first with the Dazzle, i must confess its still boxed.
