Hello,
The Nikon D5300 user found this record:
You can not decode or encode AVC / H.264 for commercial use
Other SLR camera and which also have a similar record.
Can you legally convert videos to another format, eg. QuickTime Photo .jpg? I do not know whether the encoding and decoding of the instruction means that you can not legally convert video to another format to be able to sell the movie by your own?
