My feedbacks on AG-HMC152EN

Problem 1: Multicam TC sync is not accurate. Connected two HMC152EN (different firmware version) and TC synced them. One master and one slave. Set the Timecode to Free Run. Recorded with both cameras while counting and clapping. Load it the Edius Pro 5.5 (trial) and sync the two clips with Timecode sync. When playback in multicam view, the two clips are not sync properly. The two clips are 5 frames out of sync. Other NLEs, officially do not support AVCCAM format if you want to use TC sync for multicam editing. :A

Problem 2: Super slow for parts to arrive. When I received the HMC152 unit and tested it in the shop, the CCD outputs a black/no signal to the LCD and viewfinder. The mode was in Auto and the seller (ex-videographer) was puzzled with it. After 15 min with ON-OFF-ON cycle, the CCD outputs the correct video feed. My unit was sent to Panasonic for inspection. No parts. I had to wait for 2 months for the parts to arrive from Japan. :L

Problem 3: No lock switch to prevent accidental pressing of the REC button. E.g. The Canon XM2 record button is surrounded by a rotating standby / lock switch. :P

Problem 4: Audio gets cut. During continuous recording, there is no audio for 11 frames at the end of each clips (4 GB limit).

Yikes. I can't comment on either of your first two problems (sorry). Number 3, no, you're right there is no lock switch. I've never noticed one on any cameras I've used in the last few years so I suppose I don't miss it. I've never accidentally bumped record. You can lock the switch on the top I'm pretty sure, though.... at least I think.

Problem 4 is pretty well documented. I forget the solution off-hand, but several programs are buggy when it comes to those 4GB split lines. Premiere CS4 and Vegas are definitely affected. The solutions I remember seeing involved either using the Mainconcept transcoder to go to P2 footage, or using a special command-line trick to merge the files. Do a search for 4gb split vegas in this forum and I bet you'll get a lot of results.

Good luck.
 
Regarding #4... Some people are using MTSmerger to combine split clips. It's free, and they claim it does a really good job. No experience with it myself.
 
try the mts merger for problem no. 4

i was also confused at the beginning but after merging the clips that are "cut" because of the 4gb limit my NLE runs fine with the files...
