Please...What am I doing wrong? at DVinfo.net

Todd Coffman · September 12th, 2005, 08:07 PM

I have edited a little video together in FCP. I would like to make it a DVD now. It seems no matter what I export it is (Quick Time movie or using Compressor) the video is stretched. If I use compressor, the audio isn't there either, but I can import that easily enough, but why will it not stay the same (visually) in FCP. I have tried exporting (using compressor) for 4:3 and 16:9 and it still looks stretched horizontally. I tired openig it up, after I exported it, in Imovie, DVD Studio, and IDVD and it is still stretched.
As you can tell, I'm very confused...and I don't understand this video problem either.

Thanks for the help.

Todd, I've moved your thread the Mac editing forum (it was in the PC one).

Well that explains why no one was commenting on my question.

Todd: what sequence settings are you using, and in what format did you shoot? That could at least give users a start on diagnosing your problem.

I am shooting with a MiniDV camera. (I think it's 16:9, but I have to double check that now.) the settings for the sequence are 720 X 480, NTSC DV(3:2) Aspect ratio, Anamorphic 16:9 is checked, Compression is DV/DVCPRO NTSC. Something I just noticed when I was looking at my settings, In the Quick Time Video settings, in the advanced settings under "Compressor" it lists the aspect ratio as 4:3. Is that what is giving me the problems? Because I do have Anamorphic 16:9 checked in the general settings.
What does Anamorphic mean anyway? Maybe I'll undrestand if I have a clearer defination of Anamorphic.
Thanks again,
Todd

Todd,
If you are editing a 16:9 sequence in Final Cut and not having to render every time you put a clip in the timeline, then you are editing 16:9 footage, and you should use a 16:9 aspect ratio in Compressor. Sounds like you just solved your own problem.

Anamorphic describes squeezed images, like what you are describing when you export 16:9 footage with the 4:3 aspect selected. Whenever you see a feature film projected with a 2.35:1 aspect ratio, you are seeing anamorphic footage. Instead of building cameras that use film stock with a wider aspect ratio than than the standard 1.85:1, people who want that wider ratio use non-spherical lenses that stretch the image to fit the standard stock then project it back through anamorphic lenses that unstretch (is that a word?) it back to 2.35:1. The principal seems to translate to electronic acquisition. I've shot quite a bit with a PD-170 in its 16:9 mode, and it uses only part of the CCD to record the image then stretches what it records over the 4:3 area that the camera normally records. If you check that box in FCP, it knows to unstretch the footage, just like the anamorphic lens on a projector would.

I just looked at some of the footage I was talking about and it is in 16:9 aspect ratio, however some of it is on 4:3. I had 3 cameras rolling at an event. two of them were 16:9 but one of the cameras was set at 4:3. This is going to be a big problem for my project, isn't it?

Todd,
It is not necessarily a problem, depending on how you want to deliver it. You can either letterbox all the 16:9 footage, crop the 4:3 footage to match and export a 4:3 sequence at the end or you can crop all the 4:3 footage and export a 16:9 sequence at the end. The 16:9 sequence will be much nicer for people with 16:9 TVs. For people with 4:3 TVs, I'm not sure whether there's an advantage to one or the other (it just determines whether you or the DVD player letterboxes the footage, and I don't know whether one way or the other keeps higher resolution). It will be annoying because you'll have to render either all the 4:3 or all the 16:9 footage, but it's not a fatal error. Edit as much as you can in seperate 4:3 and 16:9 sequences before you have to combine them. It will save you some time. Some one handed me footage like this for the 48 hour film project a few weeks ago, and it didn't turn out to be that big of a deal because we were supposed to deliver in letterbox anyway.
