Bitrates and motion shots
I can’t seem to word my searches to find THE answers. I like the way my projects are turning out except for any motion shots. They blur and are fuzzy and not very smooth. As soon as the action slows down, clear as a bell. Is this a bitrate issue versus compression? I’ve played around with it some but could use some expertise.
My SD projects are almost unwatchable. They were shot with a few different cameras and edited in a prores 422 timeline, they look great in the canvas, and all my stuff goes to DVD. The DVD 9 stuff is a bit better and the BluRay stuff is the best so far. I have seen DVD 5’s that looked great. How??
I have exported as a quicktime movie and in some cases sent to compressor and none of that seems too difficult, but I don’t have the handle I think I need to get using bitrates.. Are there some hard and fast simple straight forward rules that could help me make those adjustments to cure these motion issues?

They’re not in-camera motion issues? Are you working with interlaced footage on a progressive sequence? Can you add some screenshots of the motion issues you’re seeing?

How are you making a BluRay Disc with SD footage?

I’ll experiment with trying to get a screen shot of the blurring, but do you want one from the TV or my monitor?
As far as the BluRay. I made a BluRay from the HD footage shot with my HDR-FX1 Sony and some stills from the old Canon. I must say after a ton of screwing around, the first BluRay looked pretty good. I’m happy with that quality but would love to see the motion shots a slight bit tighter.
That being said, when I kept getting disappointed with the SD stuff and was repairing some old stuff that was corrupted, I thought what if I put this stuff into a ProRes 422 timeline like was suggested to me and then put it on a BluRay, I thought that the less compressed it was, it might play better. It does…way better, but still has motion sickness. I thought that maybe I could clean it up some if I played with bitrates more. Expensive and time consuming experiments though. 10 hours to encode and a couple of hours to burn and maybe a BluRay coaster or not great results. But way better than a DVD 5. I just can’t seem to get the right combo to make a decent DVD 5 or 9. Anyway, I just followed the same instructions that I follow for the HD footage with the SD footage and send to Compressor and then drag the assets to Toast 10 and knock one off. I’m sure to get scolded for this but it’s light years better viewing than what I have been able to do so far. So do you think this motion issue could be a bitrate problem?

Show me what the motion looks like in FCP, on your computer monitor.

Thanks for looking John. These were shot just a few minutes of one another with a Everio camera during our first visit to our old log cabin. This SD Video is a blurry shot is of my Wife cutting brush which wasn’t a super high activity shot but still was with constant motion. A short time later, a shot of her showing my Daughter what to do building a fire pit. The fire pit scene had very little motion and suffered less. Anytime there is motion, the shot suffers. Even with the newer upgraded Sony HDR-FX1 HD camera, motion suffers but not nearly as bad as the SD stuff. Oddly, in the same video, I shot some 1080 with my new GoPro Hero camera. Zero motion issues and by comparison, it’s a toy next to the Sony. Here’s a link. Thanks

These are screenshots from FCP? It seems like you just need to research your cameras and play with the settings, because that’s in-camera blur. If you open the raw footage in QT or some other player, does the motion look just as bad? I don’t have experience with a wide range of video cameras, so I think you’ll have to head over to a different forum, maybe the Cinematography forum or the Sony camera forum here on Creative Cow.

Actually if I take the footage after it was just shot and plug the camera into the tv, it looks really pretty decent. Surprisingly decent. It’s only after I convert it and bring it into FCP and try to choose the right codec etc.. that I can’t seem to get the right combo.
