AVCHD End to end

Post by astrolin »

I have tried to edit in HD and cannot seem to find any 1080i editing dropdowns. I have a Panasonic HDC-SD1 and can import the 1080i footage, but only see 720 dropdowns. How can I import in AVCHD 1080i, edit in the same format and write an AVCHD disk? As you are aware, every conversion reduces quality, and I would like to maintain the compression and line structure from start to finish for the highest quality.

To burn your avchd/h264 files without re-rendering them (according to your post and not lose any quality).

Open VS11+ go directly to "Share -> Create Disk -> AVCHD".
Goto Preferences and assign your working folder to a large drive and make other settings meet your needs.
Click on the GEAR Icon -> change Mpeg setting -> Customize and change your project settings to 1440x1080 Upper Field First 18MBS Variable bit Rate with Dolby Audio.
15MBS Constant bit Rate is also good video (even lower).
When you encode at 18MBS Variable Bit Rate the Average bit rate will be about 11MBS to 12MBS so the filesize is not that big.
The will allow about 46 minutes of avchd/h264 on a single sided dvd.
But your original source video files should already be compliant. IF they are avchd compliant they will not be re-encoded/re-rendered.
This is the "Do Not Convert xxxxx" settings also located under the GEAR Icon. Make sure this settings is checked ON.

Insert your avchd/h264 videos into the timeline of this burning module, create a menu & burn to a dvd. Then you can play this avchd disk in any Blu-Ray Disk player that supports avchd disks.

If you want to edit your videos first, and then burn an avchd disk then that's another topic.

Editing

Post by astrolin »

The workflow you describe works fine, but I can do that with the Panasonic software that came with the camera. I would like to edit the footage. I do understand that truly editing in compressed formats is more challenging than uncompressed video, and am willing to take the quality hit that will result from editing on anything but an I frame boundary. Will Ulead allow me to edit the HD footage in HD or can I only edit in SD?

To answer your original post for editing if your machine is fast enough try editing directly in the timeline.
You can also create a proxy file for editing (page 62 of the users pdf manual).
After editing then go to share->create disk-> avchd.

i would start with a 10 minute video as a test project first.

Hopefully someone else that edit's avchd will provide more assistance.
I haven't done much editing in the avchd format in VS.
Mainly HDV high definition video which then gets converted to avchd/h264 format.
