Well . . . hello again,

Before proceeding, I apologize for the vague language of my previous post. I didn't stop to consider the implication it suggested. So, a clarification:

I am a video and special effects technician. I am working with a client who needs videos DVR'ed in-house by his company (which includes offices in Europe) transcoded for presentation at an upcoming industry conference. My client's company owns all of the material I am to transcode. Hopefully, this explains everything adequately.

Back to the question:

I need to re-encode these files to 720p MKV. Here's how I've been doing it:

1. Demux audio with h264tsto

2. Mux video to MKV container with h264tsto

3. Re-encode MKV to 720p with MeGUI x264

At this point, MeGUI warns that the input colorspace is incompatible and asks to insert a convert to YV12 command in the AVS. Without the conversion, x264 errors out on the YUY input. With the conversion, the dynamic range of the output is badly compressed.

Is there a better way to do this for higher quality re-encoding of YUY MKV files?
