Tips on Converting FLV to Sony Vegas

1. Why Sony Vegas Pro Not Support FLV

FLV is a container file format, as its name suggests, contains data that has been encoded using various compression and encoding schemes. Such files are incapable of categorizing themselves as a specific file format and plus that Sony Vegas Pro is unable to associate FLV to a particular file format. Therefore, Sony Vegas Pro couldn't open FLV.

2. What Format Does Sony Vegas Pro Support

Here is a quick list for you to know what formats that Sony Vegas Pro support: MOV, WMV, , AA3, AAF, AIF, ASF, AU, AVC, AVI, BMP, BWF, CDA, DIG, DLX, DPX, DV, EXR, FLAC, GIF, HDP, IVC, JPEG, AVCHD, M2T, M2TS, MVC, Sony MXF (XDCAM and HDCAM SR), MP3, MP4, M4A, MPEG-1 and MPEG-2 video, OGG, MPO, OMA, Panasonic MXF (DVCPRO, AVC-Intra) PCA, PSD, QT, R3D, PNG, SFA, SND, TIFF, TGA, W64, WAV, VOX, WDP, WMA, XAVC Intra MXF, and XAVC S.

The method defined above is applicable to all the unsupported formats and is not only limited to FLV. So, whenever you come across a file format that is natively not supported by Sony Vegas Pro, simply convert the unsupported file format into a supported file format with Wondershare Video Converte Ultimate.
