I'm guessing the average write-speed required was less than that.
The write speed won't be determined by the video content.
If the card's write speed can't keep up with the camera, can that lead to artifacts? I'm guessing so.
If the card wasn't fast enough, it likely would not have worked at all.
I'm wondering if write speed is likely to be the problem
I'm with Jim. I'd also do a search of both PrPro and PE for post on the Sanyo Xacti camera files. There have been several post on all sorts of issues.
Thanks for your thoughts, fellas. So if it's not the card write speed issue causing the artifacts, what would you expect is responsible? File corruption from some other process? Codec blues?
Yesterday I put the files back on the SDHC card, and tried playing them off the camera... the video stuck... i didn't see artifiacts, but the file definitely wasn't playing back as it should.
A friend recommended I install Quicktime Pro 7 and give that a burl (apparently Prem.Pro CS4 uses Quicktime to decode MP4/AVC H.264?)
I'd love your thoughts on this before I commit US$30 to a potential white elephant.
I call it QuiRckTime, because of the many problems it causes. If you can do without it, leave it off your system.
Shoot some new footage on the card, and then play that on an HDTV. How's it look?
Thanks Jim- that's on top of my agenda!
Well what do you know- I just ran the camera in the highest res (60fps, full 1080p) and the footage ingested into Prem. Pro CS4 just fine.
Looks like my source files were corrupted somehow... either by the card not being able to keep up with the write-speed demands of the task, or during the moving of data between hard drives.
Anyway- the good news is, that the footage is now handling well. I shot continuously for just under an hour, and haven't rendered all the footage just yet- but I have my confidence renewed after todays test results.
I used my new Sandisk Extreme III - 30 Mb/s card this time around.
Glad that things are working for you, and thanks for reporting.
