Hmm, what would be ideal then as suggested by a friend of mine (Coderjoe), would be direct nhml output from DeDup.
Or maybe a high accuracy (neutral) timecode format that isn't specific to MKV or MP4 but can be converted to either format without any inaccuracies. |

Is there any reason why this might fail with ASP?
I have been getting a division by zero error. This is the first time I've tried with ASP (I've tried with one encode of the source and got the error, deleted all my files and started again). I have muxed a few files containing H.264 and they are fine, but it seems it doesn't like ASP, unless anyone else does not got an error, then it's a problem on my part somewhere. Here's the relevant info. Batch for encoding/VFR/muxing Code:

A tool that quite useful
 I search for this for a long time but finally I find none. Great work. Edit: It can't work here. By the way, I think it's easier to converting timecodes v2 to v1 than converting timecodes v1 to v2 XD The total frame number seems to be not offered in timecodes v1.

In any case you can make the script work by modifying the lines 15,16 and 18. Replace "1" with your video track ID. |

Not sure if there is much interest in this anymore, but I've recently wanted to create a VFR MP4 with MKV V2 timecodes. I tried your script zmi, but as people here have noted, it seem inaccurate. So I created my own version which seems to be accurate. The outputed timecodes once I converted to VFR MP4 back to MKV were practically the same (minor rounding errors). I don't think it's ready to be posted yet as it isn't very modular code yet and I write crappy code
, but I was wondering if anyone has samples they could provide for me so that I can test to see if I got it down correct.I need both video and audio nhml since VRF in the video will introduce a big CTS offset that also needs to be applied to the audio in order to be synced. I also need to know the original CFR. Also, thanks a lot, zmi, for your script as that is what my version was based off of. Last edited by Aktan; 6th November 2009 at 16:13. |
