disadvantages of fx1
Hi
I would like to buy the sony fx1 camcorder. I read somewhere that has few disadvantages like autofocus problem and noise recording. I cant spend over 3500$ to buy other HDV camcorders. Now i have the sony trv70 which is normal dv camcorder which has problems too like autofocus. 3500$ is too much for me so i want to make sure that i will not have such problems with fx1. Is it true the autofocus problem on fx1? thanks |
I don't use autofocus, so I can't address that. I never noticed any noise in the recording, except for the HD10 from JVC, because it's a 1-ccd camera.

not video noise but audio noise

Didn't have that, either, including using the camera mic and hooking up an external via an XLR and 1/4 inch (I believe, or 1/8) adaptor.

yes there are occasions where the auto focus is hunting and seems to take a long time to figure it out. but it's never been an issue or problem for me. I've done a lot of run-and-gun documentary stuff recently with it with very few issues.
audio sounds great. you will pick up some motor noise, but it's very, very low, but it's there. To me, the biggest disadvantage of the camera is none of the above, but the HDV format and MPEG-2 compression. But it's what I got, I work with it, and love it. If I was unhappy with it, I would've sent it back long ago, but the pictures still blow me away. |
Mike, what's your workflow? Do you use Aspect HD/PPro 1.5.1 to edit the footage?

My future workflow will be editing directly off a P2 card in my G5 or G6 using FCP HD. <wink> |
Yes... I'm tempted by G5/FCP 5 too... it's just way off my usual Wintel-based path... I guess I'll stick with the PPro for now. Now, if only HD Link (Cineform's capture/converter utility) didn't glitch on capture, it'd be the day.

Alex,
I think the glitch is hardware based. I had a similar problem that was diagnosed as Rambuss 800 being too slow. If you are using the purchased plug-in, my work around was to import m2t files from camera then convert the imported files...it makes a bit more work, but is less processor intensive...the results were very nice. |
Sean, well, the whole purpose of Aspect Hd to me is *not* to have to upgrade my hardware...
Workaround: Yes, I also capture m2t first with CapDVHS, then I fix GOP errors with Womble's tool, and only then do I Convert it using HDLink. It's OK, but of course I'd expect HDLink to do all that in one pass as it should... |
Hey all,
We're getting into editing territory. We have an excellent page on HDV editing here: http://www.dvinfo.net/conf/forumdisplay.php?f=63 Thanks, heath |
Compression and noise
Heath and Mike: Funny how we all get different impressions of stuff. I've never seen any compression artifacts or image degradation at all from the HDV MPEG compression. As for image noise, it's there for sure if you look close enough. I've yet not seen a single segment without noise. But it's at an acceptable level i think.

here are some screen grabs clearly showing artifacts. again, when played back on a 1080i monitor, they're very hard to see, and the image, YES EVEN FAST MOVING IMAGES, look fantastic. http://www.miketiffee.com/hdv/sugarbowl1.jpg http://www.miketiffee.com/hdv/sugarbowl2.jpg http://www.miketiffee.com/hdv/sugarbowl3.jpg http://www.miketiffee.com/hdv/sugarbowl4.jpg |
Awesome shots.
Being the incredible Auburn fan that I am - you wouldn't have any short clips of that game I could download do you? It would be awesome to see some of it in hd(v). |

Thanks for the example images. I clearly see the blocks of compression artifacts. Slightly disappointing, but as you say probably not even noticable when played in motion. Perhaps the shots overloaded the maximum DVI bandwidth, and as a result the camera couldnt cope. |
