“Stuttering” problem with HMC150 footage

[Tash Glenn]

Im having the same issues…Does anyone know what the best time line setting for 1080/60i SD cards Panasonic HMC-150 is?

As in frame skipping- meaning your hard drive is not fast enough to play back Pro Res. Or as in strobing- meaning you shot fast moving motion too fast or without sufficient shutter.

I believe i zoomed out too fast because it happens with two shots and the rest of the video looks fine, i slowed the clip down 75% and I tried smoothcam filter too but that didnt look good either…any other suggestions?

It’s not the stobing issue, because I took care to pan very slowly. It’s the skipping. Would it be a hard drive issue? I ordered the 7200 rpm hard drive for the 17″ macbook Pro. I thought that would be fast enough. I also have an external 7200 ESATA drive, but haven’t been using it, because it’s convenient to edit without hooking up to it.

But why would the problem happen on the HMC150 footage and not on the other HD footage from the Sony?

Appreciate your help!

That’s not fast enough for ProRes- especially HQ mode. Try the ESATA.

I will, once I get back to my ESATA External. So, is this a problem only in playback? In other words, do I need to transcode the footage again?

Probably will be fine- you’ll know by looking at it.

Hi Noah,

I tried playing back using the ESATA external drive, and I’m still having the same problem. The scene is of a school bus, rather close up, moving from one side of the screen to the other. If you care to take a look, the video’s playing on our website at https://www.scholastic.com/administrator. It’s one of the early scenes in the video within the first minute.

Interestingly, I had a videographer shoot a similar scene of other school busses. He shot on SD, not sure what the camera was, but it was a pro SD model of some sort. I believe their both 30p. His footage of the schoolbus moving through the frame is smooth–no stuttering.

What do you think? If you had a chance to look at the link/footage I sent, do you think it’s just a matter of being too close to a large moving object, thereby giving the effect of panning too quickly? And if that’s the case, why would an SD camera (inferior in quality to the HMC150 I assume) not have that problem?

Thanks again for your time

Gents – Just chiming in that I’ve encountered the same problem with my HMC 150. I see it regularly in footage, like a single frame is skipped and usually on moves. I pan and zoom slowly in the instances that I see it happen.

It’s getting to be quite annoying.
