Can't edit AVCHD

LSHorwitz wrote on 4/7/2008, 2:06 PM

I have some Canon HF10 footage I am trying to edit in Vegas Pro 8b. It seems to import fine, and the video and audio both show up on the timeline with appropriate thumbnails.

When I try to edit, there is no video, only audio. The Preview does not work at all for video. If I mix AVCHD with other types of video on the timeline, such as HDV and AVCHD, the HDV previews correctly but the AVCHD does not show at all.

I would appreciate any suggestions.

Many thanks in advance,

Larry

More often than not, Sony has introduced a new version of Vegas around NAB, which is next week.

Vegas has always been one of the first NLEs to support new formats. It has, to its credit, been very good about standards compliance and I subscribe to the non-standard AVCHD header and container being the problem. If other programs are generating AVCHD video that doesn't strictly adhere to the published standard, then Vegas might not handle them correctly. This isn't exactly Sony's fault.

I do very little AVCHD work at the moment, so I haven't experimented with it much or experienced the early adopter frustrations as I have in the past with other formats.

It will be interesting to see if any NAB update to Vegas takes place. I appreciate the Pinnacle feedback, and also suggest taking a look at Nero Vision, a program I had pretty much dismissed for any other purpose until I did some AVCHDs with it. It is actually a very competent progrm and makes especially nice looking AVCHDs. (BTW, I was never able to get it to make workable HD DVDs.....)

Terje:

You were looking for a sample of m2ts that fails in Vegas. There is a guy on the AVS forum that has run into the "audio but no video" bug and has a sample.

I have tested this and it plays/edits fine in Pinnacle studio, Ulead MF6, and in Nero. But when you try and drag it to the Vegas time line it fails. The audio shows up but the video does not.

It would be quite nice for Spot to see this too. This is most definitely a weakness in Vegas and I would rather NOT see it passed on down the line to newer versions.

Larry -

FWIW, I have a Canon HF100 (identical camera except mine doesn't have the 16GB of internal Flash memory) and have had no issues with editing the footage in 8.0b. Granted, I have mostly been using proxy files out of convenience (I don't have the fastest PC in the world) but I've been able to scrub through and/or playback the .m2ts files on the timeline. They're choppy, but they play.

I don't know if this makes a difference or not, but how are you getting your footage to your PC? Are you dragging the files directly off the card (or internal memory) or are you using the software that came with the camera (Imagemixer 3 SE?)

Edit: I downloaded and tried the file from the AVS link - nothing but audio. I will point out that this is not footage from the AVS poster's camera, it's something he downloaded from a Japanese website. Every single clip from my camera has worked perfectly in Vegas.
