I’m probably taking the plunge into an HD camcorder in the near future. However, I’m still using Premiere Pro 2.0 for editing, and upgrading _that_ and my computer system will cost a bit. So I’m wondering about converting AVCHD to DV-AVI so I can edit it (or try to edit it) with my current rig, until I spring for a new one. What are the tradeoffs– I mean, other than massive files on my hard drive? Is there a loss of color depth? Is DV-AVI limited to certain resolutions, framerates, color scales, etc.?
Take Waiwai’s info with a handfull of salt. He’s just plugging product.
Have you bought the camera yet? Are you in love with AVCHD or are you open to other HD formats? AVCHD is really compressed and every pro I’ve talked with about it says it’s a PIA to deal with.
Why not Sony Vegas Pro? It supports AVCHD editing natively. Although it does not support smart rendering, it is okay for most editing works.
If you only want to cut out unwanted scenes out the movie, you can try Smart Cutter for DV and DVB instead. Smart Cutter is aFrame AccurateH.264/AVCHD editor. Especially, only small parts on start and end points will be re-encoded, the middle part will remain untouched. This gives highest speed while reserving highest video quality. This is just ‘smart rendering’.
Editing the AVCHD video natively is probably the best strategeom, though it may put a ton of lag on a non-core (e.g. Celeron) processor. If the speed handler is not a core, 2.5 GHz for editing AVCHD should probably be your minimum. Editing MPEG-2 footage on my duo-core 1.66 GHz processor isn’t bad at all with Sony Vegas Pro 9. The lag picked uptons more inCyberlink PowerDirector 7 (consumer video editing software). From my experience, the processing to lag ratio varies A TON among the software type. Pro quality software will generally edit more smoothly and produce less lag.
Converting AVCHD to DV-AVI will limit the quality reproduction to the capabilities of both formats. For example, AVCHD and DV-AVI use different encoding systems (compression techniques and different types of losses). Converting highly compressed formats to DV-AVI will generally involve losses that are not noticeable enough to care. If the slow nature of AVCHD drags heavily, a DV-AVI conversion will probably be your best bet.
“Is DV-AVI limited to certain resolutions”
Yes…DV-AVI is standard definition (720×480, hence DV) so you’d essentially be converting an HD source to SD.
There are other codecs that will allow you to convert to an AVI that will allow you to maintain HD quality like cineform’s neo scene ($129)
edit native. once you start converting things left and right it gets’ pretty messy.
