So is Premiere doing the same thing then? Because Premiere is giving me the same results as VDub in those screen captures.
And whatever the case is...how do I get it into Premiere correctly?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

Try the same solution that works for VirtualDub: ConvertToYUY(interlaced=true).
-
You just listed one of them (via an AVI file). Another that will probably work is Avisynth Virtual File System.
-
An AVI file doesn't get the script into Premiere, just the result of it...I assumed from your phrasing you were referring to AVFS and the like. I've tried a few different things people suggested on here a while back when I asked, but I couldn't get any of them to work.

The video is flagged as BT.709. The first image (TS.jpg) is correct. The second image (AVI.jpg) is using a BT.601 matrix instead. Tell your editor the video is BT.709 (aka rec.709). Note that AVI doesn't flag the matrix. Your editor is just guessing and getting it wrong.

Premiere doesn't have an option for that...
And Ut is supposed to flag it, isn't it? Thus the different 709 and 601 options. -
Most programs don't read the UT fourcc. They just convert it to RGB with default (601 for older versions of PP), not even treating it as YUV .
The other option to RGB interlaced with 709 properly and use UT RGB to import into PP. Interpret footage as interlaced in PP
(Or use newer version of PP) -
Did you specify rec709 when you converted to RGB?
Code:ConvertToRGB(matrix="rec709")

don't forget interlaced=true switch
ConvertToRGB(matrix="rec709", interlaced=true)
If you have highlights or overbrights in the source that you want to salvage or use, you should bring them down before the RGB conversion or they will get clipped
But they were probably transmitted "broadcast legal" so you're probably ok.
EDIT: Your samples looks clipped already, probably by something upstream in the broadcastLast edited by poisondeathray; 14th Oct 2019 at 10:36.

Seems to be working but scrubbing is still super slow. I can at least play it back normal speed, but trying to scrub through to find commercial breaks isn't as fast as it usually is.
-
RGB is typically slower to decode, and more data than YUV 4:2:0 or 4:2:2. Newer UT versions have slightly improved RGB speeds.
The graphs should give you a rough idea;

Well this is weird. I had this in my script already, from the Intensity Shuttle workflow:
Code:ConvertToYV12(interlaced=true,matrix="rec.709"
-
ConvertToYV12() etc. has never worked with the dot for me. Maybe you're thinking of ColorMatrix() which requires the dot. ColorMatrix(mode="rec.601->rec.709")
-
No, I literally reused the exact same script file. Didn't touch that line until it threw the error.
-
I have another TS file. Same box, same channel. Flagged as TFF but appears to be BFF. WTF?
-
It depends on what you are doing at each step. There are potential problems with any kind of temporal filtering. Non-temporal filtering shouldn't be an issue as long as the video is treated as interlaced.
-
So I'm dealing with another of these. It seems to be working fine, right up until the conversion to YV12, at which point the chroma starts bouncing around randomly.
The script:
AVISource("beforeyv12.avi")
ConvertToYV12(interlaced=true,matrix="rec709")
I have no idea why this is happening? -
Here are the samples, because FF still gets request timeouts whenever I try to upload here.
-
Be sure the program you're evaluating afteryv12.avi with recognizes the video is interlaced YV12. It looks fine here with:
Code:AVISource("afteryv12.avi") AssumeTFF() Bob()
