T4c is a big one: part stabilization, part new features, on top of T4b, and the most contributor-driven build yet. swmarks rebuilt the CEC and screensaver handling, samtheruby backported the newer CEC kernel driver, fixed SD/VESA display modes and built in-GUI update channels, Sebastiii contributed MKV editions support, an Epson projector profile and several DV fixes, and vlix wired the skin's codec logos into the DV pipeline. On top of that: VC-1 hardware playback overhauled, a self-healing A/V sync layer for corrupt streams, AC-4 audio decoding, a nasty resume bug, per-frame tone mapping for DV→SDR, and a stack of DV picture fixes.

Release Notes

DISCLAIMER: I am not one of the developers

Hi everyone,

I recently switched to pannal p3i T4 build from avdvplus R9.

I am confused about the Append CMv4 metadata setting. Previously I kept it on Auto in avdvplus since I did not really understand what it did and I trusted the Auto to apply it when needed.

In p3i build the Auto setting is gone. The only available values are Always and CMv2.9 without L2 trims​​​, the default was Always. As I understand this would ignore the L2 metadata in the movie, which can be undesirable from what I read. So the second setting should be a safer bet since it will only add the v4 metadata when there is no L2 trim present.

Is this correct? Will I he missing out on better image quality by not appending the v4 metadata?

I would really appreciate if someone could explain this setting to me and suggest me what to set it to.

I typically watch 4K DV Remuxes available online.
