Choppy video, full of lines, interlaced?
Hi.
I’m new to video editing. I’m working on my second production with a Canon HV30 and Sony Vegas 9. So far I’ve learned a lot through Google and such. But I still have lots I don’t know.
I have a problem that followed me from the first production I did. The image is all choppy, full of lines, like the previous frame is totally interlaced with the current frame. I’m not sure what it is. I am also not sure if the image is really like this or Vegas is doing it.
On the Canon HV30 I am recording in auto mode (not P mode), with HD Standard “HDV” (not HDV30, HDV24, or DV).
The video looks great on the camera’s LCD or on the standard 29 inch TV. But previewing in Vegas, or rendered and showing in windows media player, it’s choppy.
I have a clip got when driving over a roadsing. I want to freeze on the sign, and closeup to show the numbers. I’m doing the trick of pausing preview and take a snapshot to clipboard. When doing this, the chopping effect is very visible, as I have to make a full-size preview. Strange is that on previewing it, on mode preview-half it looks good. On preview-full, best-half or best-full, its choppy.
The rendered video, played on media player, is also VERY choppy, be it Xvid 720 lines or HD 1080 lines.
Previewing the clip on the camera’s LCD, it really does not look choppy. I know it’s a small window, but I can zoom in.Here are screenshots to demostrate.
Preview half: looks good
Best half: Looks bad
Now, preview full or best full, both look bad.

Please post the specs of your machine. A screen-grab from My Computer would tell us plenty.

Well, I am confident in saying it’s not the machine!
Looks interlaced to me. Would you be willing to send me a few seconds of it to have a closer look?

How does it look like if you set “Project Properties/Video/Field order” to progressive?

Changing “Project Properties/Video/Field order” to progressive made a real improvement in this effect. At an initial look it almost eliminated the effect, while before it was ALL choppy. Thanks a lot, so far.
I will be out now for 3 weeks… When I’m back I will look further into this and hope to be able to resume the discussion. Thanks again, so far.
