Is XAVC Long-G 35 and 25 also 10 bit 4:2:2?
Hard to find answer to this even on Sony sites. Just wondering if both of these are 10 bit and 4:2:2 or is it only the 50Mb version?

10bit 4:2:2 is only on the 50mbp/s setting.
35mbp/s and lower are 8bit 4:2:0. 50mbp/s 10bit 4:2:2 is already a very low 1080 bit rate as it is in h.264. So Sony would probably never try to push 10bit in anything lower than 50mbp/s. |

Re: Is XAVC Long-G 35 and 25 also 10 bit 4:2:2?
XAVC-L HD on my FS7 is 10-bit for all the bitrates. I would imagine it would be the same on the X70 since it's using XAVC-L.
Alister stated it's 10-bit in all modes in his review: Sony PXW-X70 Review | XDCAM-USER.COM Also in the press release it states 10-bit for all 3 bitrates: Sony Announces PXW-X70 XDCAM Professional Compact Camcorder "When recording in XAVC, the PXW-X70 uses the MXF file format, efficiently compressing full HD (1920 x 1080) resolution using the MPEG-4 AVC/H.264 CODEC. Image sampling is 4:2:2 10-bit with high-efficiency Long-GOP compression at 50 Mbps, 35 Mbps or 25 Mbps." |

60i and 50i can go down to 25mbp/s.

Thanks guys.
So in conclusion the 35Mb mode is 10 bit, while the 25 Mb mode is 10 bit but only 50i or 60i correct? |
