HDV stutter on computer but not monitor
So here’s the problem: The HDV footage stutters during pans and zooms. This occurs both in my canvas window and as a final exported QuickTime file, however it does not show up on my external monitor or when the tape is played back in the camera.
Here’s the background: The footage is HDV shot at 1080i60 on a Sony 7zu. The pans and zooms are both very slow and shot from a tripod. The footage is captured to an internal drive. Here’s some info about the computer:
Final Cut Pro 7.0.2
2 x 3.2 GHz Quad-Core intel Xeon
12 GB 800 MHz DDR2 FB-DIMMI have edited many other videos in Final Cut on this computer and have only had the stuttering problem with this footage. Also, the exported QuickTime file stutters on other computers, so I don’t think it’s a processing power issue.
I tried converting the footage to ProRes and editing it on a ProRes timeline put the results were no different. I also tried dumping the original HDV tape directly to an HDCam tape and re-importing it, and once again, the results were the same.
I’m pretty sure this is the same issue this person was having, but they did not get a solution: https://forums.creativecow.net/readpost/8/1037860
Any suggestions? Thanks for whatever help you may offer!

Sorry, I think there might be some confusion about the problem. As far as I can tell, it’s not an interlacing issue. It’s not that the lines are fuzzy, it’s more a problem that the picture sticks – almost like a very quick strobing effect – during pans. I find it difficult to think it’s an interlacing issue because I work with plenty of interlaced footage in other projects and don’t experience this problem.
Though it looks fine on the external monitor, this is a problem because the final video is being created for internet viewing.
Any other suggestions?
Thanks. -
To give you a better idea of what I’m talking about, please check out the video below. It is just a few of the raw shots. It almost looks like there is a lag to the video. Anyway, please let me know what you think.

Any ideas? I’m pretty baffled that it plays so smoothly on my external monitor but on every computer it stutters just like the video above.
Thanks!

I don’t think I’ve seen a smoother, more judder free video on the internet ever. Those pans were smooth as glass. Might want to take a look at your video card or something.

Looks excellent to me, also.

From what you describe I think I have the same problem. Would be nice to check your video, but it seems to be password protected? Must be something I dont know.
Our prob is that every now and then the image seems to be split in two, part of the pic stick for a microsec or so. Result is a terrifying line sometimes across the whole screen, other times just a fwe inches long. If I then stop playback, start again, the stutter comes on another place. This is a bit comforting ofcourse, but honestly I wish the makers of editing progs like Premiere or FCP would find a way to mnake it look OK when editing – if the footage is OK.
BTW: The stuttering in my videos seems to disapear when finished movie is exported to DVD. But when editing it looks so terrible that it really scares me. So I have spent a week changing vga cards, a few different types of Nvidia based Cuda cards for Premiere Pro CS5.5. Nothing changes. Tried on computer with the nevest AMD/ATI card, even worse than on Nvidia.
Our footage was shot in HDV on a Sony camcorder, logged into FCP 6, then because Apple have decided to lock HDV files capured to FCP I had to convert every file to Apple Prores HQ to get the files over to Premiere on PC. Of course, this conversion business is what makes me worried.
Is there any way to make sure that files are OK before final movie is delivered to broadcast? It will not be rendered to DVD when delivered to broadcast of course. Either recorded on digibeta, or rendered to a computerfile they will accept.
Files stutters on all PCs we try, on LCD TV, and Ill check with old as hell TV set today. And get the guy who does color correction to check on his system.
Is there any program that will check footage and say if its OK or not, and possibly play the files as thet are supposed to look?
Best regards,
Paal
