Don't worry: x264-lossless is really lossless.

At least, according to my tests:
http://download.das-werkstatt.com/pb/mthk/info/video/comparison_video_codecs_containers.html#codec_tests

What might also be interesting is, that these tests show that FFV1.3
encodes and decodes a lot faster than x264-lossless:

encoding/decoding FPS:
x264: 94 / 190 fps
FFV1.3: 216 / 277 fps

What do you mean?
