Audio out of sync when rendering MP4s
by Matteo Bini 01 Feb '24

01 Feb '24

Hello Cinelerra GG developers, I've found a strange behaviour in this great editing software. When I render my project, sometimes the audio is out of sync. Not all the audio, but from a certain point, from half of the video the audio is out of sync and it gets worst the more we get to the end of the video. It's like latency piles up. I've only done MP4 renderings so far. My idea, but I don't know how to demonstrate it, is that ffmpeg doesn't know how to render audio and video in sync, when there's some audio that is not aligned on frames. Since I do a lot of precise audio editing in my project, there are some audio cuts that are not aligned on frames. It's not a big problem, I just wanted to let you know. The solution is very simple: render only the video track, then render the audio track in WAV and then mux them together with ffmpeg, copying the video track and encoding the audio one. This way the video is perfectly in sync with the audio. The strange thing is that, when I watch my project from the compositor window, audio and video are in sync. Thank you for making Cinelerra GG a really great free software. -- Matteo Bini

Procedure for making LPCM DVD

31 Jan '24

Start cinelerra-gg from terminal so you can see terminal output Open your source in cinelerra-gg as usual, choice format settings, go to DVD creation window. Select all values as you need, click ok, wait for batchrender window to appear In it, select second line and change codec to RAW PCM, and set it to 16 bit, signed, byteorder Lo-Hi (big endian) click "start". Cingg will finish but job is not! from terminal, note location of dvd.sh file and open it in editor running /dev/shm//dvd_20240116-182336/dvd.sh INFO: [mplex] mplex version 2.1.0 (2.2.7 $Date: 2012/11/17 01:55:16 $) **ERROR: [mplex] Unable to open file /dev/shm/dvd_20240116-182336/dvd.ac3 for reading. so mcedit /dev/shm//dvd_20240116-182336/dvd.sh and set mplex parameter " -L 48000:2:16" so full string will look like mplex -f 8 -L 48000:2:16 -o $dir/dvd.mpg $dir/dvd.m2v $dir/dvd.lpcm note, lpcm extension is important! now mv pcm file into same but with new extension (in theory you can change audio file extension into lpcm at batchrender window, not tested) mv /dev/shm//dvd_20240116-182336/dvd.pcm /dev/shm//dvd_20240116-182336/dvd.lpcm run script: bash-5.1$ /dev/shm//dvd_20240116-182336/dvd.sh running /dev/shm//dvd_20240116-182336/dvd.sh INFO: [mplex] mplex version 2.1.0 (2.2.7 $Date: 2012/11/17 01:55:16 $) INFO: [mplex] File /dev/shm/dvd_20240116-182336/dvd.m2v looks like an MPEG Video stream.

HDV 1080i to DVD 16x9 with MP2 audio
by Terje J. Hanssen 29 Jan '24

29 Jan '24

As I could not recall it : Loaded a HDV 1440x108i with native MP2 stereo audio, and then Create DVD 16x9 rendering does transcode the audio to AC3 by default. Video is displayed with correct aspect ratio using VLC and . Input #0, mpeg, from 'dvd.mpg': Duration: 00:06:58.08, start: 0.160000, bitrate: 8269 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 8000000/0/0 buffer size: 1835008 vbv_delay: N/A Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s Is it possible to get MP2 audio; if possible how and where to set it on the create DVD or Batch render window? I tried to check FFmpeg there, but could not see MP2.

HDV is really 4 channel?
by Andrew Randrianasulu 29 Jan '24

29 Jan '24

https://trac.ffmpeg.org/ticket/1258 see attached to this ticket modded decoder ... I wonder if Terje's audio really 4ch? if so,may be we can decode it to 4* wav first, then encode them correctly to bluray lpcm / dvd pcm / ac3 ...

From DV to MPG to DVD Video + PCM Audio

I want to showcase this procedure using alternative tools, and in case this sooner or later can be of some use for Creating DVD with CinGG.. *1. From DV Video w/native LPCM to DVD-compliant MPG using FFMpeg (version 4.4.4 on Leap 15.5) 2. From MPG w/o re-encoding to DVD structure and iso using DeVeDeNG (version 4.17.0 from packman) 3. Burn DVD iso with K3b from DeVeDe (or optional using Xorriso etc) * So far step 3 is not tested yet. Playback of the final mpg movie is tested with VLC and FFplay - not real tested with DVD disc in standalone players. *1.
