Cheapest all key frame HD?
What is the most economical HD format that is intraframe compression only?
Thank you. DG |

If so, you could try using X264 or XVID, setting either one to I frames only. |
Sorry for my lack of clarity.
I meant I wondered if I wanted an HD camcorder that produced a video bitstream that was all intra-frame compressed (like DV is in SD), what format(s) would I be considering? For example, DVCPRO HD is one such format, right? Thank you. DG |

Of course, don't confuse AVC-Intra with AVCHD as the latter is interframe compression, even though both are based on the MPEG 4, H.264 standard. One other note... AVC-Intra and JPEG2000 need a super fast computer to edit natively. Hope this helps. Maybe someone else knows of other HD camcorders that employ intraframe compression. |
Red, SI could also be on that list. (There are likely a whole other number of cameras as well... including HDCAM.)
2- In practice, I don't think it's useful to arbitrarily rule out cameras based on a single spec (which is a extremely poor way of predicting performance anyways). If you are interested in a clean artifact-free image, then don't look at a single spec. It is only a very small part of the puzzle. There are a number of other factors that make a significant difference... IMO you're better off looking at the end results and testing the camera for whatever you're interested in. |
