The hot camera Sony PXW-X70 records videos with the professional XAVC Long GOP, which offers up to 4:2:2 10-bit in cameras like the at up to 50 megabit/second. However, using XAVC Long GOP files is not as easy as it should be so far. This article focuses on Sony PXW-X70 XAVC-Long GOP to Sony Vegas workflow.
XAVC-L files can’t be supported by Sony Vegas Pro natively. Although Sony offers trial software to convert/transcode, at least the trial versions I have tried don’t even read professional XAVC Long GOP files, let alone transcode them. I have requested an NFR license to determine whether the issue is only with the trial versions, but I have not yet received said license.
There are several third-party software that promise to transcode professional XAVC Long GOP files. So far, the ones I have tried either crash upon opening or don’t read. The only piece of transcoding software I currently have installed that has been able to read and transcode professional XAVC Long GOP files so far is Brorsoft Video Converter.
It does a good job in converting Sony PXW-X70 XAVC-long GOP files to Sony Vegas Pro most compatible format like MPEG-2 with least quality loss. Plus, it supports encoding camera shootings in different formats (H.264 MOV, MTS/M2TS, MP4, MXF, etc.) to video editing software compatible file types, i.e. MPEG-2 for Premiere Pro, DNxHD for Avid Media Composer, WMV for Windows Movie Maker, AVI to Pinnacle Studio to meet your different needs.
Encoding Sony PXW-X70 XAVC-L files to MPEG-2 for Sony Vegas Pro
Step 1: Run the best XAVC-L to Sony Vegas Converter, and click the “Add” button to load XAVC videos from PXW-X70.
Step 2: Click “Format” bar to determine output format. Follow “Adobe Premiere/Sony Vegas” and select “MPEG-2(*.mpg)” as the output format. Besides, you can also choose WMV (VC-1) (*.wmv) if you want to get a relatively smaller output file.
Step 3: Adjust video and audio parameters, including the Bitrate of Video and Audio, the Codec of Video and Audio, Video Size, Sample Rate, Frame Rate, Audio Channels, etc., in the Profile Settings.
Step 4: Click “Convert” button to start encoding Sony PXW-X70 XAVC-L to MPG for importing to Sony Vegas Pro.
When the conversion task is finished, click “Open” button to get the exported files and then import the converted Sony PXW-X70 XAVC-Long GOP footage into Vegas Pro 10/11/12/13 to do further editing without hassle.
P.S. What’s GOP (not the political party) and i-frame?
For those unfamiliar, GOP is an acronym which stands for Group of Pictures. Both Panasonic and Sony offer both i-frame (intra frame) and Long GOP versions of H.264. The i-frame versions compress every frame individually, and are heavier (require a higher bit rate to achieve the same picture quality) but are more easily editable with older, less capable computers and older editing software. Long GOP versions only include some of the frames completely, and in other frames include the differences that appear in subsequent frames. Long GOP versions are more efficient, and therefore can give very high quality at a much lower bit rate.
