Xh-a1 & Hv30 Using 30p Not Mixing In Fcp

Lately I've been shooting 24f with the A1 and 24p with 30. For Multiclip I convert the HV30 24p HDV (which is in a 60i wrapper) to true 24p HDV with a Reverse Telecine in Compressor. You'd probably get slightly better results converting both to ProRes but I don't have that kind of disk space. My droplet is here:

However, when I go to mix them together in a multiclip sequence, I get the error that says I am using different codecs.

When I check the format properties of each clip, the XH-A1 has 108030p listed under compressor while the HV30 has 108060i. Why is this different?

Normally I down convert on ingest so I have not experienced this problem in the past. Any suggestions would be greatly appreciated.

I have shot 30f on my XH-A1 for a while now. I started before Apple created a 1080p30 Easy Setup in Final Cut 6. Back then, I had a hard time figuring out what settings to use. After asking a few people on the forum what I should do, the consensus was to use the 1080i60 Firewire Basic Easy Setup.

When I captured the 30f footage from my XH-A1 using the 1080i60 Firewire Basic Easy Setup it appeared as 1080i60 in the browser (under "Compressor"). When played back and exported the footage was in fact progressive 30f, although it listed the compressor as 1080i60.

It was explained to me on the forum, that the 30f footage is stored on the tape at 1080i60, but when viewed is progressive (this was my experience). Unlike dealing with 24p/f, there is no pull down added to the footage. Since HDV can only be recorded to tape at 1080i60, dealing with 24f footage is a problem for the HV-30, because the camera does not flag the added frames, making pull down removal a little more complicated. 30f captured using the 1080i60 Firewire Basic setting and edited in a 1080i60 timeline eliminates the need to transcode the footage, which is a very good thing.

I just got my hands on a HV-30 and am running a couple tests of my own to see if I am right. I suspect that your problem is using Apple's 1080p30 Easy Setup, rather than the 1080i60 Firewire Basic. I will keep you posted.

I finished running my tests mixing footage from my XH-A1 and HV-30 this morning. All footage was shot at 30f/p and captured using the 1080i60 Firewire Basic Easy Setup in Final Cut Pro. As I suspected, there was no problem placing the captured footage from the different cameras in a 1080i60 sequence (using Final Cut Pro 6). This makes it pretty clear to me that the problems you were having mixing footage stems from the 1080p30 Easy Setup you used to capture your footage. My suggestion is to ignore this Easy Setup and capture all of your 30f/p footage using the 1080i60 Firewire Basic Easy Setup. The footage is marked "1080i60" under the "Compressor" section of the browser, but the footage is clearly progressive (image below).

If you have any more questions, please don't hesitate to ask.

Thanks for the tests. one question:
Did you try to make them a multiclip?
if this works (i currently don't have access to both cameras to test myself...) it would be great!!!

I just put a multiclip sequence together using the footage from both cameras. The clips combined with no trouble at all. They share the same codec, frame size, and rate, so mixing the footage is no longer an issue. As I said before, I suspect that the trouble mentioned in the 1st post of this thread stems from using Final Cut Pro's 1080p30 Easy Setup. If you ever use both cameras for a project capture your 30f/p footage from both cameras using 1080i60 Firewire Basic.

I pasted a link below to the thread that initially helped guide me in the right direction a couple of years ago.

I experienced a similar thing with Windows. I captured both the XH-A1 and HV30 shot in 30p with HDVsplit and imported into Adobe Premiere. The HV30 footage showed up in Premiere as 60i, and I had to right click on each HV30 clip and select interpret footage and select progressive.
Seems something on the HV30 isn't flagging 30p for the various NLEs.
