GH1 720p30 mode

Although the GH1 can record using AVCHD, it can also record to Photo-JPEG which is very EZ to edit. One potential issue -- recording is at the non-video rate of 30.00fps rather than 29.97fps.
I've got video samples, but no way to host. |
Steve,
If you would confirm for me, the video bitrate for the JPEG video is 30.8 Mbps? I'm just not used to seeing numbers that high in a consumer product. On the other hand, the audio numbers, especially the 16 KHz sampling rate, confirms that anyone half way serious about shooting with this will be recording double system audio. 16KHz might be OK for dialog, but not for any kind of musical performance. |
If it’s a bandwidth issue, you can either upload it to a file sharing site, Vimeo, or I’m sure Chris Hurd wouldn’t mind hosting them.

Can you upload them to Vimeo? IF you do so, you can set it so that others can download the original files (if they have a free Vimeo membership.)
I'm keen to see and play with any examples from the GH1. |

Steve, Thanks. Just trying to make sure what little I know, I know.

Thanks for posting this info. I'm really look forward to seeing some clips from this camera, other than the tiny ones on the Panasonic website. There must be a few typos in the Panasonic specs for the camera DMC-GH1 | PRODUCTS | LUMIX | Digital Camera | Panasonic Global It does say Motion Jpeg, Photo Jpeg is unusual I think as a camera codec, but I'd welcome it as it's great to work with even if it would fill up memory cards pretty quickly!

OK -- here is the link to ExposureRoom:
Steve Mullen On ExposureRoom - Videos Remember these are 3rd generation videos. Anyway, I was checking for motion judder because I could see noise in the prototype which meant it was not a unit I was going to use for pix quality checks. You can also see the AF and AE at work. The zoom ring was so stiff there was no way I was going to try zooming while shooting. Big negative for run & gun. The other negative -- I have small hands and the grip was WAY too tiny to feel good and to feel solid. Pana skimped it a crucial area. The switches and manual controls were wonderful. The symbols made no sense to me or to the rep. Enjoy! |

Some software will blend frames instead of just dropping, but that looks terrible, and causes a weird periodic blur that comes and goes every 33 seconds. Cheers, Anna |
You could also "Conform" the footage to 29.97p in Apple's Cinema Tools. That would change the audio sample rate and require FCP to convert the sample rate in the timeline. To me it's better to manipulate the audio rather than the video.
You could also process the audio separately from the video by making AIFFs from the original video file and just remember to remove an audio frame every 30 seconds to keep it in sync. A dropped frame in video is usually obvious, not so with audio if it is chosen carefully. |
