Capturing from the HV30

Having spent my half hour on Yonge shooting with the brand-new HV30, it was time to capture. I’m using Final Cut Studio 1, so Final Cut itself is version 5.0.4 on my 1.6 GHz G5 tower. I connected the HV30 to the G5 via the Firewire 400 port on the front panel, with my capture drive plugged into the Firewire-800 port to keep the two devices on separate busses.
Setting the in and out points for batch capturing is the same as regular DV, but doing the batch capture itself seems to run into timecode errors on a regular basis. I seemed to hit an error every other or every 3rd capture, but clicking on OK sent FCP back to work and it would capture everything okay during the 2nd or 3rd attempt. The capture window for HDV is different than the one for regular DV, and you don’t get the image mirrored in FCP as you capture. Not a big deal as I normally watch the camcorder’s flip-screen during capture.
Capturing the first shot, the 24p, took no more time than usual, once I’d gone through the first timecode error message. Putting the clip on the timeline prompted a red render line across the top of that window, so I started to render. FCP said it would take 9 minutes to render the 30-second 24p clip, but I think it was closer to 4 minutes. Exporting said clip to QuickTime (without conversion) took seconds—it must spit out the render file pretty much as is. Here’s the 24p footage after Youtube got its hands on it:

I exited FCP and set up a new project in order to capture the same clip using Apple’s intermediate HDV codec. The 30 second 24p intermediate clip didn’t require rendering, and the export prompted a warning of 11 minutes, which was probably less than 2 minutes in total. Here’s what the lower-res 24p footage looks like:

Exiting FCP again, I set up a 30p project file. As with 24p, FCP indicated rendering was needed. The 30-second 30p clip generated a 2-minute estimate but actually took about a minute and a half to render, so it’s clearly less complicated for FCP compared to the 24p clips. I’m no engineer, but I’m guessing that it’s easier to pull the 30p data off the 60i tape feed from the camcorder. Exporting the 30p clip took a few seconds. And here’s the clip:

The next setting was the plain-Jane HDV, the 1080i format. Capture wasn’t a problem, and putting the clip into the timeline prompted the red render line. FCP initially reported 12 minutes to render, but the counter fluttered between 10, 11, and 12 minutes in the first 30 seconds or so. In actual time, the rendering took about 10 and a half minutes, so for 1080i, FCP guessed fairly accurately. Again, the export to QuickTime took 4-5 seconds, and this is what it looks like:

Capturing a clip shot in regular 60i standard-def DV was problematic. The easy setup choice for DV didn’t work—I kept getting timecode errors. I went in and played with the manual settings (mostly by selecting something else and then going back to the proper setting), and it started to capture. I got the audio rate mismatch error message when it was done, so I’ll have to go back and try to match what is undoubtedly not a 48k sample rate on the camcorder. Strangely, I had to render the clip once I plopped it into the timeline—clearly it’s not pure DV or I’ve missed a setting somewhere (the clip appeared fine in the viewer, but was a tiny square in the middle of the Canvas view before and after rendering). I went back to the manual the next day and realized I had left the HV30’s export setting at HDV instead of switching to standard-def DV—I’ll do a another test with the other setting to see how it turns out. Exporting this first attempt to QuickTime took just a few seconds. Here’s what it looks like (don’t squint too hard):

Finally, I set up a FCP project to compare the 24p and the 24p Apple Intermediate codecs. FCP didn’t seem to like me mixing the two on the same timeline as the image sizes changed when I dropped the 2nd type into the timeline. I set up some graphics and some split-screen action to compare. Rendering took about 2 minutes, and the export took less than 5 seconds (clearly, those render files are going straight into the QuickTime files). Here’s the comparison as it appeared:

This clip took very little time for Compressor to convert to the Youtube settings as detailed at Ken Stone’s site (here’s the article that I followed to set up Youtube 4:3 and widescreen presets) compared to DV clips (it takes at least 3 hrs to render a 2-minute DV clip, so the two formats are clearly quite different). The other HDV clips took much less time than past DV clips I’ve converted using these settings, too.
The Youtube website itself took longer to upload those clips, so any speed gains in Compressor seemed offset by slowdowns with YouTube. I had assumed that HD footage would take longer for both steps, so it’s a fair tradeoff.
Next time, I hope to have my 2nd field trip tests and results, this time to explore the different manual and preset options, and to try setting the export settings to DV for the old-school shots.
