Loves my A-1's, BUT!

If you have a "dropout" upon capture but then can do it again and it captures OK, then it's not a dropout. It's an issue between the computer and the camera. Could be a firewire cable, or something else. But it's not a dropout. If there's a dropout on the tape it's permanent.

I've shot more than 50 hours of tapes with my XH A1, and am familiar with footage from 2 others in town and none of us has seen a dropout at all. Using Panasonic AMQ tapes.

I too have been experiencing what seems like "dropout" issues with the XHA1 and Panasonic AY-DVPQs and MQs. The MQs say right on the housing "for HDV" so I thought I should at least be OK with them...

I first noticed the problem this summer while on a remote international shoot using only the PQs. The biggest problems seem to occur on the first ten minutes of each tape where I would get dozens of dropouts. I had gotten these tapes from a vender that I had never used before, and when I tested tapes from my regular vender when I got home, with no apparent problems, I chalked it up to a grey market tape stock issue. But, I just got back from another shoot, using the MQ tape from my regular supplier and while some of the tapes are capturing without a glitch, others are showing 20 - 25 errors a tape. The strange thing is if I capture the tape again, I get about the same amount of errors, but not necessarily in the same spots!

I question the statement that it can be blamed on a capture issue, cable, or hard drive speed, etc. My software will stop the auto capture process when that happens.... Mine keeps on capturing, simply making a divide in the clips as though it was a new clip, loosing of course about 5 seconds of material. Not so critical on B-roll, but not nice during interviews ….

If I use the camera to capture, the flip out screen on the camera, as well as the confirm monitor on the computer, goes beige at the same point as the glitch, indicating that it is a playback issue, not a capture issue. The really strange thing is that on the problem tapes, it does not happen at the same points on the tape if I capture it the second time.... So, while you may be right that it cannot technically be a "dropout" on the tape, something else is causing “intermittent interruptions” or "breaks" during playback on some tapes, where the problem is repeatable, but not on the exact frame.

Someone else said that they were having the same problem with 2 A1's which makes me concerned about my next purchase. I have another international shoot coming up where I need a reliable system. I doub't there will be time to send my unit in for repairs before I go. I don't mind ordering another A1 as they are cheap enough, and I have come to like the camera and the images I am getting, when everything works. I just don't want to order another one if this problem seems to be symptomatic of this particular camera.... Enough people are reporting the problem that it makes me suspicious ….

If you simply play back the tapes in the camera, watching in your viewfinder or flipout screen, do you see any problem?

[Frank Spangler]

OK, On closer inspection, the breaks do hapen in the same places, almost every time, not as random as I previously reported. When just playung back, the scene freezes over the area of the break. It looks like a tape issue, or a dirty head or something. It is funny that I never had one dropuout for the first 3 months of using the camera and now I am getting quite a few.

What are the recomendations? Send it in for cleaning? Switch to Sony HDV tapes? Clean my self with cleaning tape and forced air as some here suggested?

thanks

I'd use the cleaning tape first. Read the directions and use it according to the directions--overuse is not good, although sometimes if the gunk doesn't go away they may say to use it a second time.

Did you use the cleaning tape when you first got the camera? That's one of those things you're supposed to do. I 've been using Panasonic AMQ tapes and haven't seen a dropout yet. I run the cleaning tape after I've been shooting in dusty situations and after about every 50 hours of recording.

some drop outs i find are recorded ones [ie they show all the time where recorded on]smetimes i get play back ones that just show up but if the tape is replayed over the same spot do not show again,this is with sony premiums as the amount i get has not tempted me to hd tapes as of yet. the play back drop outs are nothing to do with the pc as it can happen playing to tv as well.

It's a CAMERA dropout even if it doesn't do it again. The reading isn't always perfect. But the issue is not the computer in this case. This is isn't your simple firewire connection problem etc, the dropout is EXACTLY the same as when the camera couldn't read a frame or two. Meaning the GOP is broken but audio continues fully etc.

Exactly! That's what I meant.

[Frank Spangler]

Is this dropout issue normal with the HDV format - just something you have to live with, or are some cameras better then others? Form now on, when shooting interviews domestically, I think that I will be covering myself by firewiring to a backup deck. But, on my international shoots where I often shoot in remote villages, that may not be a good option.... A second battery opperated camera, perhaps??? I hate to have to carry a second camera around .... Getting the one, along with my still cameras, laptop, hard drives on to airline carryon, is becoming more and more of a challenge!

Hi again,

Well I went in to Canon Service in Toronto today to pick up my camera. They told me that the problem wasn't with the camera but with the tape and that they cleaned the head, which is very hard for me to BELIEVE!!
They also told me not to use DAMEGED tape in the camera, first of all I always use brand new tapes secondlly which idiot will use a damaged tape with his/her camera.

I am going to run some tests in the next few days and will let you all know.

By the way should I change tapes to Sony or to stick with Panasonic AMQs??????????
Let me know guys!!

Well since this thread was resurrected, I thought I'd make a comment as stated before by several people on here. If there was anything to the "use a cleaning tape before 1st use", I wonder why manufacturers haven't included that in manuals or at least some sort of additional literature.

Just curious.

[Matthew Amirkhani]

I found out that the original Canon HDV tapes are all made by Sony. Therefore, I changed my tapes from Panasonic to Sony HDV tapres and Iam very happy no more problems.


Thanks
