Oh, Okay. That was simple, I will give it a go, Thanks Pandy.
I have "-acodec ac3" so it should be replaced by "-c:a copy" right?
Update:
I converted the .m2ts file's DTS-HD track to DTS using TSMuxerGUI then used the modified commend for DTS and it worked, According to media info I got a .ts file with a DTS soundtrack plays in the computer with no drop outs or sync problems. Now I will have to see if the deck records it and plays it back, Fingers crossed, will report back.Last edited by dellsam34; 12th Feb 2019 at 14:30.

Yeah, The DTS sample as it is didn't record well, only shows frozen frames, I should probably reduce the video bitrate, So DTS is 1509 kb/s so I have to reduce the video bitrate by 1.5Mbps. Let me give it a try.
No it didn't work, froze to death, I tried two combinations, This:
HTML Code:ffmpeg -i Input.m2ts -c:v mpeg2video -r 30/1.001 -b:v 20500000 -bufsize 9781248 -maxrate 23000000 -bf 2 -sc_threshold -30000 -seq_disp_ext 1 -color_primaries 1 -color_trc 1 -colorspace 1 -dc 10 -me_range 960 -inter_matrix 16,17,18,19,20,21,22,23,17,18,19,20,21,22,23,24,18,19,20,21,22,23,24,25,19,20,21,22,23,24,26,27,20,21,22,23,25,26,27,28,21,22,23,24,26,27,28,30,22,23,24,26,27,28,30,31,23,24,25,27,28,30,31,33 -c:a copy -muxrate 25000000 Output.ts
HTML Code:ffmpeg -i Input.m2ts -c:v mpeg2video -r 30/1.001 -b:v 20500000 -bufsize 9781248 -maxrate 21500000 -bf 2 -sc_threshold -30000 -seq_disp_ext 1 -color_primaries 1 -color_trc 1 -colorspace 1 -dc 10 -me_range 960 -inter_matrix 16,17,18,19,20,21,22,23,17,18,19,20,21,22,23,24,18,19,20,21,22,23,24,25,19,20,21,22,23,24,26,27,20,21,22,23,25,26,27,28,21,22,23,24,26,27,28,30,22,23,24,26,27,28,30,31,23,24,25,27,28,30,31,33 -c:a copy -muxrate 25000000 Output.ts

My deck is capable of playing back DTS encoded tapes, However not sure about recording it.
-
SOrry for hijackng this thread again, but back to my previous problem, I think there is an easy solution. Can soneone who owns a D-VHS dech record anything from DV or analog source in STD, then transfer it to PC to a TS file and upload an extract of MediaInfo log about parameters? This could be easily used to make a specialized, or universal coding matrix for STD D-VHS master for both PAL and NTSC to encode MPEG-TS D-VHS compliant stream that can be fed into the software and recorded onto tape.
-
These files are SD MPEG2 compliant files that can be recorded to the deck via firewire with no problem, You will need a XP machine.
-
Thank you, however those are NTSC clips and I have a PAL machine, this is why I asked if someone could just send MediaInfo output and I would use the information to perfect the encoding parameters for PAL output. I will download then and chech the info and then maybe I will be able to do what is required. Thank you for help. Those files are not recompressed in anyway? You simply used mpg extension instead of ts?
OK. So the first and main problem is the ffmpeg exceeding the maxbitrate. the max bitrate is 14,1Mbps and yet the encoded file is 18,2Mbps. And it completely ommits the audio.
Any tip on how to keep ffmpeg from exceeding set max bitrate?Last edited by SF01; 20th Apr 2019 at 17:21.

That's all what I got, Those files can be recorded to a NTSC machine with no modification required, I tried them. Yours being PAL and probably SD only makes it very limited in terms of recording capabilities via firewire. It is better to open up a new thread since the title of this one doesn't apply to your case.

-
Are you getting warnings from muxer? You can switch to non linear quantizer in MPEG-2 to increase compression
-
No warnings.
How do you suggest I achieve that?
And why possibly is audio not encoded...
EDIT: The audio is not recoded, because TS does not support PCM. MP2 worked fine. But the videobitrate is still over the tolerance.Last edited by SF01; 21st Apr 2019 at 15:34.

So, I got a second D-VHS deck, this time a NTSC model from Japan, Panasonic - NV-DHE10. And I started searching information on how to record again, and I founf this thread, started reasing, and lo and behold my amazement, when I see myself from 4 years ago with little to no knowledge, a real blast from the past.
Anyway. The PAL D-VHS deck can accept DV signal, I couldn't get it to work with CapDVHS though and DVHSTool doesn't even want to start, even in XP-compatibility mode. Anyway, I will just get a DV passthrough-converter, like some Canopus ADVC, so that it gets detected by PC and I can send DV stream there and output the other end to PAL D-VHS.
Now, the NTSC D-VHS is a more interesting topic. Turns out, a compliant file can simply be rendered by Vegas. I was already using Vegas to record VHS and S-VHS by creating DV master, sending it via Print to tape function to D8 camcorder converting to analog on the fly via analog outputs and recording analog tape (I run a small, underground VHS label now). Imagine my curiosity, when went to render menu, chose a regular MainConcept MPEG2 -> Blu-ray 1920x1080-60i, 25 Mbps video stream ad in the customize template in the output type, where it says MPEG-2 there is a dropdown menu, that when you open it you will see the D-VHS at the very bottom (along with ATSC, if needed). The other settings surely need to be adjusted, but basically it can produce a ready on the go file that CapDVHS will happily record on tape (if it won't get the can't start tape transport error) and transfer back, more or less without glitches, I got some glithes, because I was testing on S-VHS tape. And by the way, both my D-VHS machines, PAL and NTSC, can record D-VHS on S-VHS tape eithout drilling holes in them. The Panasonic one also has the S-VHS ET functionality.
After gaining some insights since this topic was last active, I will probably be able to modify the aforementiones scripts and incorporate them into a workflow that will also include muxing 6-channel AC-3 audio. I'm not sure about the DTS, as not all machines supported it, mine says nothing about it, so it probably won't work with it.
One last bit grinds my gears, D-Theater featured LPCM audio track, I wonder if it would be possible to incorporate that as well.Last edited by SF01; 18th Oct 2023 at 16:09. Reason: 4 years not 3, wow...
