Re: Support for HEVC?

Astra have recently started broadcasting a 12 minute 4K/HEVC loop on 28.2 East.
Here's the TS file if it's of any use:

[RESOLVED] DGIndexNV in taskbar but not on screen

Just had the problem where DGIndexNV (2048 on Windows XP SP3) starts up and exists on the taskbar but isn't visible on the desktop. I tried resizing the screen (while running DGIndexNV) thinking that might move it back into the visible area but that didn't work. I then followed this suggestion on th...

Re: Asynchronous H.264/AC3 output with erroneous TS recordings when using DGDecNV

These suggestions are a bit of a bodge. In the final encoded and muxed file (MP4 or MKV) try hitting the 'J' and 'K' keys in VLC to adjust the audio delay by +/-50ms. Also the audio delay can be adjusted in MPC-HC. Once the position of the audio change is known (caused by missing frames) and the app...

Re: Issues with version 2047

Just to confirm that the license has changed for me as well with 2047.
Error message just says "Invalid License!".

Only tested on WinXP (32bit) so far. I'll test Vista (32bit) and Win7 (64bit) tonight.
I've gone back to using the last version for now 2046.

Re: Artifacts When Decoding

I noticed that your source is NTSC 29.97fps http://www.mediafire.com/?dd8v9spkfo4j6j4 I think the original source (that this was taken from by the broadcaster) is likely to be 25fps. So this means you probably have telecined source - telecined from 25fps to 29.97fps. I'm not sure which method they u...

Re: Lip sync for BBC encodes from HD channels

All seems ok with the new v2046 with HD streams from BBC channels and Ch4. I've not seen any lip sync issues since the new version.
I used to apply an extra 100ms audio offset correction to Ch4 HD source but that doesn't seem to be needed any longer.

Re: Lip sync for BBC encodes from HD channels

Ajidamal The problem might be caused by the video editor your using. VideoReDo tries to correct the audio by bringing it into sync with the video - it tries to reduce the audio offset to 0ms. TS Packet Editor has a similar feature called Timecode correction but you'll still finish up with a small au...

Re: [RESOLVED] Lip sync for BBC encodes from HD channels

The only problem I've had is with 6 channel audio from HD channels from the BBC. Because the nearest 'I' frame is about 30 seconds before the start of the programme the audio is 2 channel upto where the programme starts and then switches to 6 channel. DGIndexNV decodes only 2 channel audio and mixes...

Re: Lip sync for BBC encodes from HD channels

Yes, that seems to have fixed it. Here's a 40 second sample (25MB) https://db.tt/nL0f1VVe The old version of 2046 gives an audio offset of -1289ms which needed correcting by +360ms to give -929ms. The new version of 2046 gives an audio offset of -1129ms (a difference of 160ms) but it appears to work...

Re: Lip sync for BBC encodes from HD channels

I'll check tonight. For 6 channel audio (from HD channels of BBC channels) the correction seems to be about +60ms to +80ms compared to -360ms. I suspect they're offseting the video w.r.t the PCR clock. The biggest 'I' frame gap so far has been 17 minutes 43 seconds long in a news programme which con...

Lip sync for BBC encodes from HD channels

The BBC changed their HD encoders again on 14th Nov 2013. DGIndexNV 2046 now decodes the wrong audio offset. Here's a sample: 38 second sample of Byzantium A Tale of Three Cities part 2 from BBC 4 HD (19MB) https://db.tt/MXIzTTG7 To correct the lip sync you need to subtract about 360ms from the audi...

Re: Adding Support for Japanese ISDB-T SD to HD Program Switching Detection

With TS Packet Editor you can switch the SD stream off and create a TS file containing just the HD video and audio streams. Use DGIndexNV on this modified TS file to create the DGI, AAC and AVS files. When the AVS is viewed in AvsPmod frame 0 and 1 contain upscaled images from the SD stream. Adding ...

AC3 packet size is 32ms. If using the trim command in the AVS script and pre-editing the AC3 audio length using Audacity (to match the trimmed video) then the formula for calculating the audio length needs to be something like this (assuming the audio delay is 0ms). tA = ((INT((tV*1000)/32+0.5)*32)-...

Re: Cutting out adverts with trim and in-sync audio

Thanks, I've give both ways a go and see what happens. I noticed you used 173 as the trim point - that's probably a good idea with interlaced video. Assuming frame 0 is the first frame that gives 174 frames in total. The sample video is 25fps so the audio would be cut at (174*1000)/25 + 552 = 7512ms...
