After shooting videos with Sony PMW-F5/F55, how to do the post editing to those XAVC videos on Final Cut Pro, Sony Vegas or other editors is really a headache for many users. That's what this passage is specially written for.

1. How to Make XAVC Editable on
Editors Like FCP/Sony Vegas

2. You must have heard of these buzzwords-"XAVC", "4K" and "Sony
PMW-F55/F5", have you? Ever since the first day when the two
marvelous camcorders Sony PMW-F55/F5 hit the market, they have
been the subjects of feverish speculation. We have heard a lot about
the 4K Camcorders, such as their size, appearance, accessories,
etc. But what attract us the most is their strong shooting
performance-the PMW-F5 can record XAVC videos with 2K
resolution at 30 fps at one hundred Mbits/s while PMW-F55 is able
to shoot XAVC with 4K resolution at 30 fps at 300 Mbit/s and 2K
resolution at 30 fps at one hundred Mbit/s. Thanks to the F5 and
F55, the XAVC was brought into sudden fame.

3. We also heard much about the unique XAVC format: it was
developed by Sony, it records 4K resolution at 60 fps can delivers
outstanding video quality and goes on and on. Except for these
advantages, we also heard many complain about it, for example, "I
shot some family videos with PMW-F5 but when I was planning to
edit it in Final Cut Pro, I was blocked.” Or "I’ve tried to get 1080p
XAVC footage from an F5 to work in Sony Vegas 9. It imports, but
when I try to do anything with it, it crashes.”

4. The reason for the problem is simple and obvious: XAVC is not a
popular video format accepted by most current applications such as
iMovie, FCP, Sony Vegas(exclude Sony Vegas 12), etc. To make
XAVC editable on those professional editors, the key point is to
break the format limitation. To put in simpler, we need to convert
XAVC to Final Cut Pro acceptable video format like Apple ProRes
422(MOV).

5. Honestly, it is not difficult to get rid of the format incompatibility issue
once we have got a professional third-party tool. To cater for the
requirement, Doremisoft XAVC Converter was specially
developed. It is considered to be the "XAVC incompatibility killer"
since it can convert XAVC to any other video formats(MP4, AVI,
MOV, FLV, WMV, etc ) as well as transfer XAVC to all popular
software, for example, transfer XAVC to iMovie, import XAVC to
Sony Vegas, XAVC to Adobe Premiere, etc. Have to mention that, it
can also help to transfer XAVC to lots of popular media devices for
playback freely such as iPhone 5/4S/4, iPad, HTC One, Blackberry,
Nokia, PSP, Xbox, etc
