No, the numbers don't tell you about video noise. The 170 is much better. The only pro camera that I know about that matches the 170 is the DSR-390 and the 170 still might be just a bit better.

I'm not sure either about which camera is more sesitive: PD170 or DSR-570... We all know that DSR570 is a high-end broadcast camera that surpases PD170 in almost every aspect, but, what about low light capabilities... ? Maybe bigger chip and lens means that more light is needed, don't you think so ? I once worked with a DSR-570 and I must say that it is sensitive, but not much sensitive than a PD170. That suprises me.

Has anyone done any A/B comparisons ? That would be welcomed.

Best Regards.

Yes it has been done and the results were posted on DVInfo.net. Bottom line, the 170 is better in low light.

Hey Mike, do you remember the post of this comparison?

Robert, I was talking about the DSR-500. I know DSR-570 is better under low light. The problem is: maybe I´m about to work with both at the same time, the PD-170 and DSR-500. A friend of mine said DSR-500 is MUCH MORE SENSITIVE under low light than PD-170.

It's weird isn't it ? DSR-500 or 570 is at least 5 times as expensive as a PD170 and the PD170 is slightly better in low light.

How can this be possible ? Is there any technical reason that explains this fact ?

I'm sorry but I've worked with both and the 500 (WS) is definitely not as useable as the 170 in low light.

DSR 250 zoom motor noise?
 

My DSR 250 has very loud motor noise when I zoom fast, both my vx2000's don't even come close to that noise, slow zoom no problem, has any encountered this before?


Thanks
Mike

DSR-250 iMovie problem
 

Hey guys, trying to export to tape (share) simple wedding video onto DSR-250. Have no problem importing video from camera to TV. When I click share to videocamera, iMovie goes through the process of beginning its export. The DSR250 LCD screen goes to record pause mode and then just quits. iMovie gives a message "lost camera connection. check connections, etc..." I have. No problem. I have restarted computer, powered off and on camera multiple times, and umplugged the Firewire cable multiple times to no avail. Of course I am in VTR mode. Also, when viewing edited video in the iMovie window, no video shows up on the LCD screen of the 250 even though I have selected "play video through to camera" in the preferences of iMovie. Any suggestions or help? Have done this successfully many times before w/the 250.

woops
 

Meant to say no problem importing tape from camera to COMPUTER not TV.

Try deleting the iMovie preferences.

Where are the iMovie preferences located at? Thanks in advance.

imovie problem
 

if you recently download final cut HD or some other program of that type on you computer that could be the problem. if you have, then you are going to have to take it off of you library before imovie will work.

Yes, I do have Final Cut HD as well. I installed FC Pro about 6 months ago. Not sure if I have used iMovie since installing FC-I'm thinking I have used it for another project but not positive. Do I just delete everything that is Final Cut related? Are there any hidden files I need to delete as well? Preference files, etc .... Thanks for helping out this amateur.

Update! I have tried the following things since last post: 1) deleted iMovie preference file, 2) deleted Final Cut HD and related apps, 3) rebooted enough times w/many different configurations-firewire plugged in, firewire unplugged-camera on, camera off-etc...., 4) repaired permissions. Yes, I am in VTR mode. Yes, I have plenty of tape (blank). Write protection turned off. There is no problem importing tape from camera to computer. Also, when importing, iMovie CAN control the camera. That would lead me to assume that communication is indeed going both ways. Is there some special communication when attempting to export (share) back to videocamera? This is happening now on two of my cameras: the Sony DSR-250 and Sony DCR-VX 2000. Never had a problem before now-even with Final Cut installed. Could I have firewire ports gone bad? Apple did replace my motherboard free of charge earlier this year. Have done several successful projects since then. I have a dual 2.0 ghz G5 w/512k RAM. Should I reset the CUDA switch? If I can't get this figured out, this machine is going back to Apple. Need help from all you pros. Thanks in advance.

There is no problem between iMovie and FCP HD or other versions of FCP, that I'm aware of. We have both programs on the computers at the school I teach at and there are no problems. Have you reinstalled iMovie, repaired permissions etc.? What version of iMovie are you using? Is iMovie in the Applications folder and is the Applications folder in the default location?
