Import JVC GY-LS300 files to Vegas

jmnvideo wrote on 5/19/2016, 4:07 PM
Anybody have this camera? I got it last month, and I'm wondering what the best way is to get my files to Vegas Pro 13. I am having to use Adobe Media Encoder to transcode the files from Quicktime (.mov). I could shoot in AVCHD instead but I want the best quality. Seems like there should be an easier way.

Yes, I do.

I downloaded Catalyst Suite, which comes with Catalyst Prepare, and I am hoping that this will make my life easier. It's been a while since I have been on this forum. I 'll look through the posts here to see what others say about this software. I see now that there is a Catalyst Edit, too. Is this the new successor to Vegas? If so, then it should have a lot of the functionality of Vegas as I feel that Vegas Pro is still the most intuitive editing software out there.

For what it's worth, I found some native UHD MOV files from this camera on the JVC site, downloaded them and dropped them on my Pro 12 timeline without any problems.

Thanks, Mike. I am not sure why I am having problems, but once I figure it out I will post it here.

By the way, if anyone is considering this camera, I am very pleased with it so far.

You may want to post a link to a stop start (short clip) or at least post the "Media Info" on camera source the file. You may be able to re-wrap the camera original data into an .MXF format that Vegas will understand better. My guess is JVC is not doing anything special with its recording format.

According to the JVC website, the camera records h.264 in 4K mode, which would effectively be XAVC-S or L. You probably just need to use FFMEG and copy the AV codecs to the properly to the .MXF format. You could then create a .BAT file that you could drag and drop camera media to, or convert whole directories of media at a time.

Uploading a sample file would help me and others help you better.

I think that I have narrowed down the problem. It occurs with files that are shot in 50M YUV422 HD mode. There doesn't appear to be any problem dropping other files shot with the camera, whether Quicktime or AVCHD, 4K or HD, directly into the Vegas Pro 13 timeline.

The good news is that Catalyst Browse, a free program, will transcode the footage. But I'm not sure if the 422 color space is retained.

Try transcoding to XAVC-Intra. These will become MXF files that Vegas can read as 422.
