File errors (Bad SEI detected/too short?)
I'm desperate for some help on this. I have about 60 files that are just sitting on my PC that I can't burn because of this error.
I'm having a ton of problems with some files that I have. They were originally captured with my Hauppauge HD PVR and then edited with VRD. Once I author my Blu-ray with MultiAVCHD, I get a files that "jump" (for lack of a better word) a second or two after they start. It's not huge but it's about 2-3 frames, I would say. When I ran them through tsmuxer, I got an error that said "Bad SEI detected. SEI too short." If I select "Do Not Change SEI," it processes fine but the jump is still there. Is there any way to fix this? Is re-encoding the only option? Since MultiAVChd uses tsmuxer to create the discs, this anomaly is there on all of them. The odd thing is that I've done nothing different with these files than I normally do when recording. Is this something that VRD entered into the equation? Or is there any chance of it fixing it? Here's an example of one of the files: General ID : 1 (0x1) Complete name : J:\Test Format : MPEG-TS File size : 442 MiB Duration : 4mn 26s Overall bit rate mode : Variable Overall bit rate : 13.9 Mbps Video ID : 4113 (0x1011) Menu ID : 1 (0x1) Format : AVC Format/Info : Advanced Video Codec Format profile : Main@L4.0 Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Format settings, GOP : M=3, N=24 Codec ID : 27 Duration : 4mn 26s Bit rate mode : Variable Bit rate : 13.0 Mbps Maximum bit rate : 20.0 Mbps Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate : 29.970 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Top Field First Bits/(Pixel*Frame) : 0.210 Stream size : 414 MiB (94%) Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.709 Audio ID : 4352 (0x1100) Menu ID : 1 (0x1) Format : AC-3 Format/Info : Audio Coding 3 Mode extension : CM (complete main) Format settings, Endianness : Big Codec ID : 129 Duration : 4mn 26s Bit rate mode : Constant Bit rate : 192 Kbps Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 48.0 KHz Bit depth : 16 bits Compression mode : Lossy Stream size : 6.10 MiB (1%) Language : English |

OK so I was just able to reproduce the error. It *IS* definitely a problem in videoredo. It's not a problem with the master file.
I've uploaded both the original recording and the edit and the errors are introduced AFTER videoredo. ORIGINAL: https://mega.co.nz/#!xRFXmLRD!4-wdDz...L5D95M82CiSbs8 AFTER:https://mega.co.nz/#!kRVX3YhK!3eqneH...lo4T0oDfnmtq7A And to see the (slight) jerkiness that I'm talking about, here's a smaller clip: https://mega.co.nz/#!xd9XhZqI!i7Jla3...AAvOgyXYguq8Uw And, to be clear, this has happened with various versions of VRD. It's not just one. The files that I initially noticed this on were recorded several years ago. The files I uploaded were recorded today. Last edited by DigitalfreakNYC; 10th August 2014 at 19:09. |

There's some more info from VRD at this point. It seems that ALL of the Hauppauge recordings that are edited with VRD are screwed up. Because (I guess) the SEI is unstable due to the way the Hauppauge makes recordings, it is only made even worse by VRD. They're recommending running it through TSmuxer FIRST before editing so that the SEI will be re-written and everything will be fine once it's edited.
A few frames are recoded around every edit point with VRD so there will likely be some sort of problem at every edit with Hauppauge files. It also depends from player to player how it will manifest itself. From one of the authors: Quote:
However, from this point forward, I'll run every recording through TSmuxer FIRST and then go from there with regards to editing and burning. It's just shocking that it's taken 4 years to find this problem. |
