We tested the latest DNx SDK upgrade (2.7.0.48) on Mac and Linux. On Linux we found that decoding some files now produce corrupted images. On Mac, the same works fine. Let me know how I can provide a sample file.

Hi Viktor, I understand. We are looking for a solution that works on Linux (and Mac)... Eric

Hi, We are looking into using the new DNxMXF extension to read and write MXF files for interop with MediaComposer. I did not find if or how we can read and write some basic metadata fields. The basic ones we are interested in are: - Timecode - Material, Source and Original Source Package UIDs - Tape/Reel name Is the plan to augment the SDK to support

I get that error when attempting to encode 1920x1080 frames with DNX_HQ_COMPRESSION_ID, DNX_SQ_COMPRESSION_ID or DNX_LB_COMPRESSION_ID. Why is that? Thanks, Eric

Hi Viktor, thanks for the detailed explanation. So, should I undestand that from the DNx SDK user's perspective, this DNx feature really augments the range of possible values in the DNX_ Uncompressed Params_t and not that of the DNX_CompressedParams_t (as I was led to believe in my original post)? Also, as the DNx stream won't keep the original

Just tried with DNxSDK 2.4.2 and this issue is still present.

Hi, I'm now using DNx SDK release 2.3.5.43. Release notes for the 2.3.4 release say: 10/12 bit-depth support is added for DNX_HQ/DNX_SQ/DNX_LB (1272/1273/1274) compressions However, the DNX_GetInfoFromCompressedFrame() never returns 10 or 12 in the depth field. :-( I call DNX_CreateEncoder with the following: (gdb) p compParams $3 = { structSize

MediaComposer 8.8

Is alpha stored with DNxHR in QuickTime done the same way as for DNxHD? For DNxHD we expect the alpha to follow the rgb in one QuickTime chunk, and the rgb size to be stored in the last 4 bytes of the chunk. With the DNxHR files exported from MC, I don't see the rgb size in those last 4 bytes... Eric

I discovered DNxHR QuickTimes from Resolve import fine in MediaComposer. These have a ADHR user atom. This seems to be what is missing in our exports. I found the following which describes them. http://community.avid.com/forums/t/136517.aspx Hopefully this will help.
