motion blur with HD720p30?
I am looking for some advice on a few different things.
1. We are videotaping our church services using the JVC GY-HD110 using HD30p mode. We have the option of 24p, 30p, and SD60p. We typically don’t do a lot of panning and zooming during the service, but if we do, I’ve noticed that everything seems blurry, even if the pan is real slow and gradual. Is this what we can expect when using a lower framerate like 24p or 30p? I’m very new to HDV editing with a decent camera, so I’m not sure what results to expect, but the results we’re getting can’t be normal for this camera. Any tips or advice for filming in 30p?
2. We’re capturing our footage with Final Cut Pro (final cut studio 2) and the sequence is setup for HDV-720p30. After everything has been edited, we export it Compressor and then encode it to mpeg-2. We typically use 2-pass VBR best with the average bitrate at 6.5 and the max around 7. I have tried bumping these up to nearly 8 with similar results though. In addition to the motion blur that I described above, the other problem we’re seeing is that the footage just does not look good once it has been encoded. If someone told me the video was shot with an HDV camera, I wouldn’t believe them. The video doesn’t look any better than the video I shot and edited with my own personal digital camcorder that cost me $700.
What I’m looking for is the best process to import this 720p30 footage, edit it, encode it, then burn it to dvd using DVD Studio Pro 4. I have to be missing something, or doing something wrong to be getting these results. I’m new to this though, so I have a good excuse 🙂

If your final delivery format is SD DVD then you should shoot the weddings on a camera like an SD camera like a Sony PD170 which has good low light performance.
HDV wont make SD output look any better and the trade-off for high resolution is reduced low-light performance.
The blurring issue sounds like JVC’s motion smoothing option for 30p. If you turn it off you will have a ‘filmic’ strobe effect. Again you may as well shoot SD 60i and create SD 60i DVDs. Motion will look smoother but not blurry, and progressive displays will just de-interlace it as needed.

Interesting. A guy at the company we bought the equipment from suggested always filming in the highest resolution possible. In this case, that would be HDV-HD30p. Then, in the software, just use that footage to create a standard resolution dvd with the 16:9 aspect ratio.
So, you’re saying that it doesn’t matter if we film in SD or HD, if the final output is standard resolution, it’s going to be the same?
