HD into SD timeline issue

[Shane Ross]

[santellavision] “I tried to drop that into an Uncompressed 8-bit SD timeline to downconvert and make a DVD”

Why are you doing this? I export right from the DVCPRO HD timeline to Compressor and then make the DVD. The step you mention is unnecessary, and might be adding the interlacing you are seeing.

[santellavision] “I’ve shot and am cutting in DVCPROHD 30fps. Looks great. I tried to drop that into an Uncompressed 8-bit SD timeline to downconvert and make a DVD.”

As Shane notes, this step is completely unnecessary, just send your DVCPro HD timeline to Compressor and go.

But did you shoot 720 or 1080i? If you shot 1080i, that’s Upper Field First native so when you dropped it into the 8bit SD timeline, you reversed the fields and it will look very ugly.

Shot 720P30. I was also trying to lay to BetaSp using AJA Io (No Kona yet) So, I can’t do down convert thru Kona at this time. What’s the procedure to drop the 720P timeline into a Uncomp8?

Have never had to do this, but my guess would be you might have to move your footage one pixel up or down vertically to get rid of your interlacing issue. Also ensure that the distortion is not causing any issues.

I’d also turn off the field rendering on the timeline to keep it progressive. Another way to do this is to export a reference movie in full resolution and then use compressor to do an advanced format version to Uncompressed 8bit NTSC.

Moving it a line didn’t help. Turning off the fields as mentioned before does work and it looks good. But what Edit to tape, any issues with laying to Beta with the fields set to off?

Thanks you guys for your help. I just bought my HDX900 HD camera and this is my first HD project. My next purchase is the KONA 3 card.

You’ll just have to try it and see what happens. I always use my Kona 3 to do the downconvert from 720p to SD in realtime and whatever the card does, it looks great.

One last question. I think I’ll just get the KONA 3 and make this easy. Is it working OK on a 2.66 MacPro? And what do you guys use for ‘Ref In’ to it? I’ve been searching posts and can’t find that.

been running quite a while now on our Mac Pro Quad 3.0. I have a Horita BSG-50 black burst generator for ref.

OK, So, my old analog NTSC burst gen will work, that’s great. You guys all got me convinced the Kona3 is the way to go.

Walter, did I read somewhere that you can keep and use a AJA IoLA for analog vid/aud outputs for dubbing?
