I think i made a decision: I'll wait for the next canon cameras. Maybe there'll be something like H1, but not as expensive as it. (I read Steven sold his H1, maybe he is and you all are right that a1 is a wonder, I'll think again)
and anyways thank you all for replies

regards

Hi John. I moved from XL2 to A1 last december, and I totally agree with you that the XL2 is better for SD. The pictures are somehow more solid with the XL2 and don't have that shifting/smearing of fine details that happens sometimes with the A1 when you move the camera.

But I would probably agree with your decision to wait for the next generation of cameras to come along, if you don't need it now. The market for SD must be winding down so buying an expensive SD camera doesn't look like a good idea. Or maybe you could pick up a cheap second-hand XL2?

3DMax? Am I missing something? Since when did that become an edit app?

Richard I have just posted a question relating to the smearing problem you mentioned, does this happen in HD too?

if you add some matrix bullet effects or explosions or i dunno what else, you have to render it into movie with MAX. A desktop pc needs days of time to render HD shots with reflection/refraction (like matrix bullet effects). With SD you need 1/4 of time you would need with HD to render the same scene.

You surely work more with premiere final cut and vegas, but Ive always used max for everything: from text on screen to color correction, motion blur, to special effects, just everything^^

OK, new Quad Cores from Intel do wonders, but I am not up to buy a new computer. (btw in December new Inter's 45nm CPU are coming)

Ahh... ok sorry. You made no mention of any 3D compositing, so it read a bit funny to me.

Yes indeed, but there seems to be only a small number of users who report seeing this. I think it is most likely inherent to HDV encoding, but I would be willling (and happy) to find out it is something I am doing wrong while shooting.

Thanks Richard, my footage was actually shot in SD.

Here is the link to my original question

when something is broadcast or projected, there is typically anywhere from a 5% to a 20% crop from the source image.

if you’re going to shoot a "film-like" project, "dark corners" will be the least of your worries. You'll be cropping out boom mikes, crew, and lights... on a good day.

don't judge a camera based on how it performs with a third party adapter.

nobody in the A1 group is going to tell you to buy the XL2.

and for the record, the amount of pixels has quite a bit to do with image quality.

i just shot this clip below in grand cayman – HDV to SD, 24f, Canon WA. i've included
a wide range of shots to show color, dof, skin tones, bright and low light, and range.

The XL1 or 2 does not come close to the image quality of the A1. Any grain present is due to the stream. The source is crystal clear.

eric-

those were lovely images. thank u for sharing your efforts.

as someone who has not had a single client ask for hd, i'm still working in the world of sd. my work is usually screened at presentations or has been used for ntsc sd broadcast. that said, i'm still looking at the a1 but mostly for sd acquisition (and for any hd that rolls my way)

based on your obvious ability to extract lovely images from the a1, would you please explain some of your workflow, specifically the presets used on the interior and exterior shots AND most importantly, the propose of down-converting the hdv into sd.

sorry if i've asked a newbie-ish question. i'm still doing my homework.

thanks in advance

be well

Rob,

I was actually in the same situation when I picked up the A1. The cam performs best in HDV. The SD options are pretty much useless if you’re coming from another Canon prosumer model. I’d advise against shooting anything in SD with it, but HDV and the HDV to SD is outstanding.

My workflow is to record in HDV- either 60i or 24f depending on the subject. I don’t really use presets. I’ve created my own on the fly, mostly just adding some saturation.
The color temp controls are usually enough in most cases.. and to be on the safe side I try to shoot as flat as possible. I use Vegas 4 and 7 and add any color correction in post. Everything on my sample is right from the cam. I just shot it and it’s still on my timeline.

For SD down, I import with an HV20 and set it for DV OUT. It down converts the 24f material nicely and I can also monitor the HDV version via the HDMI. Once in Vegas, it’s just like editing SD/.avi, but with more options. With the pixel ratio you can do 16x9, 4x3, or 4x3 with a 16x9 mask and implement some track motion.

I will also go back and selectively cap some HDV footage for HD B-Roll.

For the spa interiors, I was at 1/48 shutter and even down to 1/24 at times with db from 0 to +3. I used mostly natural lighting to preserve the ambience of the spa. In the darker areas I used a single 200w lamp bounced off the ceiling and set the color temp a bit warmer in-camera. The cam is quite clean in low light, though I wouldn’t push it past +6.

Exterior was shot at 1/48 with the in-camera ND to 1/32 at 0db. F-Stop was probably 2-5.
Some of those shots may have been in 60i too with typical settings.

I’m also overexposing my shots by a notch or two. I find I get cleaner results.

If you are on the fence about the A1, don’t be. It’s an amazing cam with tremendous features. In the right hands - for HD it performs just as well as anything you would see on broadcast and for SD it will take your work to a whole new level. Just don’t shoot in “Auto” anything. As a professional, I’m sure you will be in Manual anyway…. just a heads up that the auto features are horrendous.

Also, be prepared to drop some coin. Some “must have” additional items will probably include the Canon Wide Angle, an HV20, a Lanc remote, HD monitors, and a whole new computer when you become addicted to the HD footage.
