Exporting to DVCAM issues

gatekeeper1337 wrote on 8/27/2002, 8:31 AM
I have captured video 720x480 using the YUV. I have rendered the video as a 720x480 NTSC DV. When I watch the video on the PC everything is fine. But when I use the print to tape function, the motion of the video is choppy and there are horizontal lines of choppiness in all of the video that was originally YUV. The other video that isn't YUV plays fine and has no problems. Any suggestions?

I'm guessing that the media properties for the YUV clip are not set right for field order. Perhaps it's set as "none (progressive)" and it should really be lower field first or upper field first.

What format was the oroiginal source material, and what tools did you use to capture it?

I have the ATI 8500DV. I used the RCA inputs on the dongle connected to a VCR. It is possible that I it is on progressive. Can I convert those files or do I have to recapture them?

Okay I looked and it is lower field first, not progressive.

This problem is what I had and spend a week solving it, even installing the TI 1394 drivers (which was a BIG mistake) and reinstalling everything.

Having a 1.6ghz system with ultra fast hard drives, I, too, wondered why I had problems. It all came down to hard drive and the interface speed.

basically, when rendering from my main 80 gig drive (partitioned 30+30+20) I had problems, but when using a different drive connected through a different IDE cable everything worked perfectly - even though it was a slower drive.

After moving/reconnecting/changing drives for a couple days and trying everything, it really comes down to the speed of the IDE interface. The interface on the motherboard was just not fast enough. Everything worked when the drives were run from a Promise Technology Ultra 100 TX2 IDE controller.

Try getting one of those and plug a second drive into it. Also, check your VV settings. Insure the prerendering temp drive is that drive (it defaults to drive C: ) Once I had the drive in and routed all temp files and rendering to that drive all printing to tape was perfect.

as a test, I had the same file on the main drive and it had your problems when rendering to tape. Just switching the temp drive for prerendering to the other drive made everything work. after all, it is that drive where it renders the video and gets the files to print to tape.

I have 3 drives. 1 40GB (5400RPM), 1 60GB (7200RPM) and a 120GB (7200RPM). All temp and raw files are on the on 120 and the rendered are on the 60. The 120 is on the Promise card and the others are on the DMA100s on the motherboard. I don't think it is a problem because I have used my 60 to print to tape and never had any problems. It is whenever I have YUV in the video. I created a test file, half DV and half YUV. When rendered, the DV that I used plays fine but the YUV goes choppy. Again, I don't think that speed is an issue.
