I just got my HMC150 (very happy)

turned it on after charging everything, switch to 1080 24p shoot some stuff (i made sure i formatted the SDHC card)

putting it in Premiere CS4 there is terrible artifacting all over the video.
I'll upload a pic, but its digital artifacting, its cut into 4 lines horizontal, made from the artifacts...

Any ideas or remedies?

will give more info when i get the chance

Right click on the video in the Program panel and change the Quality from Automatic to Draft.

This will not affect the final rendered video, only the preview in Premiere Pro. Native AVCHD is a beast to edit even on a beefy computer.

How's this for terrible artifacting?

I get these type of errors randomly. Some shoots there are no problems, others will have many errors like this. Same card, same camera. The errors are visible when viewing the native files in VLC, and after the log/transfer process in FCS 6.0.5. Anyone else seen anything like this?

Thanks~

Does that happen when you play the footage back in the camera? Or only after it's been transferred to your hard disk?

I'd suspect that the footage is good in-camera, which means there's nothing wrong with the footage or with your memory card. But something fishy is happening when you transfer it over.
 
Weird... looks fine in the camera- even after archiving it to a data DVD and moving it back. I might see about trying the log/transfer process again.
 
Well, here is the re-log/transfer attempt. Looks fine in the camera.
Card specs: RiDATA 16 GB Class 6 SDHC card. This problem also happens with a SanDisk 8 GB Extreme III Class 6 card...

PS... in addition to the FCS spec mentioned above, here are the machine specs:
Mac 2x3 GHz Dual-Core Intel Xeon, 4 GB 667 MHz DDR2 FB-DIMM, OSX 10.4.11

Footage was 1080i

Is it happening after about 30 mins of PH mode footage. That could be the glitch where separate files are put together within a single clip.
 
Unfortunately, no. It is rare that I record long clips (I'm usually shooting >5min interviews and b-roll). THe example is from a clip that is less than 30 seconds long. It occurs randomly. I'll have some shoots that have absolutely no glitches, then others that will have them randomly in some clips, and not in others - all shot within seconds of each other. When I first saw it, all I could think was "oh no, banding - need to get the head cleaner out..." Ha!
 
I'm having the same issues. Weird glitches / artifacting and they occur after transcoding to prores. Any solutions? If I need to use toast to convert I will..but it is a bummer.
 
At least it's not in the camera. I too have had artifacting which really challenged me to do some clever editing to cover up the mistake on a film that couldn't be re-shot >.<

.....but yeah hopefully in time the NLE's and software will update/adapt/whatever they have to do for it to work right.

keep your fingers crossed guys
 
I reconverted to ProRes and the same artifacts showed up in the same spot in both clips. Unfortunately, this is a wedding so I can't do much to cover it up :/.

I'll try toast. Ugh..this really sucks.
