16 bit truncation to 10 bit

Guest 2 · Post by **Guest 2** » Sat Jan 30, 2021 10:06 am

From DGSource: "If the source video has 10-bit depth, the decoded video is delivered as 16-bit and is reported to Avisynth+ as pixel format P016. If the source video has 8-bit depth, the decoded video is delivered as 8-bit and is reported to Avisynth+ as pixel format YV12. If you need a reduced color depth (less than 16 bits) for your high-bit-depth processing, you can use ConvertBits() as needed after your DGSource() call."

If I decode a 10 bit source and DGSource outputs 16 bit, is the ConvertBits(10) lossless? I.e. are the discarded bits useless?

Soitenly, they are all zeros.

Rocky is off whizzing around doing who knows what, so I am in charge right now.

Hey Curly
Nice to know that you are in charge while Rocky is having a whiz.
@Guest 2
DGDecodeNV just pads the last six bit positions with zeroes
and ConvertBits(10) just removes the padding

EDIT
Needed a reason to make the first part of the post

You are a funny guy. That's why you are Curly Approved!

To be precise, NVDec does that padding.

I am currently in charge. There is no crisis at DG Tools. Rocky's recovery from the accident will be swift.

Get better soon, Rocky. We are praying for you.

Kisses, Brit

Guys, I had nothing to do with it, I promise! Boris was seen lurking in the vicinity.

Where to get information on Rocky's reported death?

DG will issue a statement at the right time.

Guilty conscience Sherm?
First DG disappears by accident, and you bring up Sherman Tools,
then you bring up being a moderator and Rocky crash lands.

Do I need a lawyer?

Stay quiet Sherman! Don't talk to anyone. Don't answer any questions.

You're looking in the wrong direction Mr. Peabody

Quite right. Thank you.

Sherman is speaking to investigators and is providing valuable information. Though he was in the vicinity he was tracking Boris and he feels terrible that he wasn't able to intervene in time to prevent the attack. Sherman passed a lie detector test and no charges are expected to be filed against him.
