Gray screen flashes in Blu Ray source in Vegas 13.0

[badmojorayman]

At seemingly random intervals, Vegas 13 inserts these gray frames with noise in them into Blu-Ray footage. Sometimes there are 2-3 instances, this time there were 4. I'm using Pismo File Mount Audit Package to virtualize my AVS file into a readable AVI. The AVI reads perfectly (no gray glitch) outside of Vegas. I have disabled GPU rendering. I have unmounted and then remounted the AVS file. Sometimes, in the middle of the gray frames, there is a jumbled frame or two from another part of the footage.

Has anyone seen this before? How did you overcome it?

What is your avs? Are you using a frame accurate source filter ?

Are the glitches visible in vegas' preview, or only after exporting from vegas ?

Why are you importing a blu-ray movie into Vegas? If you just want to cut out a scene, then ffmpeg is a better option.......

[badmojorayman]

The streams were extracted by MeGUI. This problem happens in both rendering and previewing in Vegas. The problem always occurs at around the same timecode, even when the footage is adjusted by cuts. Sometimes, the gray frames disappear and become the original frames while rendering, making it really frustrating.

The AVS:

LoadPlugin("X:\Users\*****\Desktop\Video Tools\MeGui\tools\ffms\ffms2.dll")
FFVideoSource("C:\Movie\F1_T2_Video - .mkv", fpsnum=24000, fpsden=1001)
ConvertToRGB32()

Is it an AVC blu-ray disc ? Try threads=1 for FFVideoSource

If it is AVC or MPEG2 BD, then you can import the .m2ts directly into vegas . It doesn't look like you are doing any manipulations with avisynth

[badmojorayman]

That's a good suggestion, but am I determining AVC by how the stream is defined in MeGUI? I'm not sure how I would know the original codec going into it. It's currently rendering, but I will try adding that to my script for my next test.

[poisondeathray]

You can use mediainfo to determine the video compression

Just copy it over as m2ts (that is what it is on the blu-ray), and it will open in vegas directly unless it's VC-1 . VC-1 will not open in vegas, and FFMS2 can have problems decoding it

If the goal was to edit in vegas, you don't need to use avfs with that script (it's doing nothing) , or use avisynth or megui. All you are doing is adding a bunch of overhead making everything slower

+1 for PDR's advise.

[badmojorayman]

This is the knowledge I was missing since I started doing these projects. Thanks so much.

[badmojorayman]

Using the M2TS directly is SO MUCH EASIER! Thanks a ton! It also brings in all of the language tracks and alternative mixes. How do I determine which tracks to eliminate? (There were 17 or more) Should I continue to use MeGUI to extract just the audio version I need?

[_Al_]

Try tsMuxer, load that m2ts, check streams you want to keep, choose m2ts as export.

[badmojorayman]

Awesome! That works perfectly, and I was already using tsMuxer to create ISOs of my finished projects. One new problem however, and I assume I can leave you guys alone after this. The project renders to 50% and then stops. (The timer continues to count) The file size remains 0, so I assume that Vegas is unable to continue after doing the first pass. I just tested it using scripts and other containers, and it doesn't have this problem. What am I missing?

[badmojorayman]

Has anyone else encountered this?

[poisondeathray]

What final format are you exporting ? Did you mean other formats export successfully using the same project ? Or only with different projects ?

Did you try disabling GPU acceleration ? It can cause problems in some cases

[badmojorayman]

I'm exporting 2 versions, one at 480p and one at 1080p. Both are m2v. I just successfully rendered a small clip by setting a 10 second loop region, but the full project still hangs as it's starting the second pass.

GPU acceleration is disabled. I used to have that problem. I disabled it under preferences.
