Footage plays out of sync in Final Cut Pro

Question

Footage plays out of sync in Final Cut Pro

Hey all!

I was given AVI files that I coverted to MOV files. Once I placed them in my timeline I saw that they were all out of sync. I checked the format and it says that the audio format is 32-bit Floating Point. I am guessing this is the problem as the sequence settings only allow me to pic 16 bit or 24 bit. These files are also out of sync when I play them through quicktime player and MPEG streamclip....

The guy I got this footage from (A PC user) had no problems with the footage being out of sync...

Any ideas on how I could fix this????

Final Cut Pro 7, Mac OS X (10.6.8)

What did you convert to? ".Mov" is not enough information. That only says you converted it to the QT format. But what CODEC did you convert to? Animation? PhotoJPEG? H.264? DV/NTSC? ProRes?

OK, sorry about that. When I pulled the DVD into MPEG Streamclip I exported it to DV, the compression says DV(DV25).

Some of the files I had I opened in QuickTime pro and used SAVE AS to get it to a MOV. If I used the export function I did not get the correct size as it was shot in 720x480 16:9...

Does that make sense?

how much out of synch? a few frames? if so, you may not be monitoring the audio the same way you're monitoring the video. Go to view: audio playback and make sure audio is following video or that the signal path is the same as view: video playback.

720x480 isn't 16:9. that's 4:3. 720x360..that's 16:9.

Unless it's anamorphic in which case the image will looked squeezed horizontally if viewed with the anamorphic flag.

This is the other DILEMA I am having....it was shot at 720x480 but in widescreen.....this has caused me a lot of problems in the conversion too.....Here are the sequence settings that FCP makes when I bring the clip in.

If you don't know, I don't think I can help. All NTSC (North American) DV video is 720x480. 4:3 video fills the 4:3 screen and displays properly in final cut. 16:9 video in DV can either be anamorphic in which case the pixel dimensions are still 720x480 but the image is squeezed horizontally or it can be letterboxed with black bars on the top and bottom.

Everything will be ok within fcp but when you export from fcp you may or may not get an image that's displayed properly. If you're having a problem with this post back, describe your current workflow, and we'll walk you thru the steps you need to take to make the exported file disply properly.

It looks ok, as good as it is gooing to get I think. The guy who shot it shot it with these settings, he said he shot is SD but hit the widescreen option. The problem that I am facing now is that the original files that he gave me (AVI Files) and the ones that I tried to export to MOV files are all playing out of sync. I have played them all (original and exported) in FCP, QT and MPEG Streamclip, and all is out of sync.

He said when he played these AVI files on his PC they played back fine...

can you test the original files on a pc? Just cause he said they played ok...

Can you manually resynch in fcp?

If you have a short avi and want to send it to me, I'll take a look. My email is mgrenadier@gmail.com

Workflow:

Some of the AVI files he gave me were not accepted by MPEG Streamclip. He then burned the files to a dvd for me which I brough into MPEG Streamclip and exported to DV. This is how I got the exported file:

I did not change anything...just hit "export to DV"

For the files he gave me as AVI's (which he forgot to burn for me) I opened those in QT Pro and did save as to give me an MOV. When I tried to export it, it gave me the wrong size as there was no option to export 720x480 16:9....

I only have files that are far too large to email 😟 I suppose I will have to try manualy resyncing and hope that there are not more problems down the road...

I really do apprecaite you trying to help...
