Great!
Unfortunately I did my last full-dvd-encode just yesterday and I've no projects on hold, so it needs some time until I can test it Thakns for your work Nic! Cheers Koepi

Yaaay! Congrats! The only MPEG-2-encoder I'd ever use turns 0.60!

Great! I have 4 SVCDs to encode for a friend and I just started the first pass on the first disc with 0.59 - might aswell abort it and use this version
Quick test with a few small test files: No more crash when running several instances in 2pass mode. Quality seems as good as with 0.59b4 if not slightly better. Thank You |

Hey NIC thank you !!! With you and Hank who needs more to use not freeware MPEG2 encoders?

@Affar: When I put that AVI clip in VDub, it says it has 149 frames. When I encode a M2V file and run it through BitrateViewer, it says it has 149 frames too. What discrepancy are you seeing and how do I replicate it.

i tested the .avs with Tmpgenc 2.5 and MainConcept 1.4 aswell and guess what, exact same results. mpeg stream eye says 149 frames for all of them by the way. also tried loading the avi in to Tmpgenc and it said 177 frames. tried MC and it said 149 but actually encoded 1 less (147 frames, 148 pics read in bitrate viewer). weird avi. so sorry but this is not a QuEnc problem since the other encoders are encoding exactly the same.

Nic,
I have a question for you: can you explain what algorithm you use to calculate the SCR? In mencoder I used a series of tricks ( something similar to: for every pack scr = Gop initial pts + (delta data/ N) where N is the sum of video and audio data I'm about to mux ), but I realize it's a flawed and too simplistic method. Often it works well, but sometimes audio pts diverges too much from scr; additionally it's impossible to manage multiple audio tracks. I'm looking for better alternatives. Thanks. |

@unifxs: Thankfully libavformat takes care of it for me SCR is a pain, I remember coding ReJig and that being one of the most difficult problems for getting DVD compatability just right. I honestly can't remember that much about it now. Sorry. I remember MPUCoders forum had a nice thread on it once.

Another question about the new tool tips: Scene Detection --- Bad for DVD encoding Closed GOP --- Recommended for DVD encoding From my experiences with CCE just the opposite should be true. Cheers manolito |

@manolito:
1Pass VBR has always been a bit flaky, due to it's very nature. 2Pass is definitely the way to go. 2 Pass also enable the XviD ratecontrol. But I'll look into seeing what I can do. "From my experiences with CCE just the opposite should be true" What experiences are those? Could you elaborate. In reality any which way should be fine. Scene Detection can cause bizarre GOPs (i.e. very short GOPs) that a DVD player might not like, but I'm sure most don't have a problem. Closed GOPs are useful for seeking, but aren't necessary. Share your experiences...Are you talking from a quality point of view? If so, then closed gop = false and scene detection = true would probably equate to better quality. -Nic ps @dgz: What changed between beta 3 & 4 again? I can't remember (Ok, time for me to start using a CVS or at least write a changelog) |

just my humble opinion
Scene Detection --- A few dvd players may not like it 100% Closed GOP --- Only required for multi-angle DVD encoding or editing Quote:
lmin = 1 * FF_QP2LAMBDA; to lmin = 1; or lmin = 0.6 * FF_QP2LAMBDA; since if you remember the use of lambda caused undersizing with 2 pass for over about 4000Kb/s. actually, just looking, i see you have lambda in the low bitrate setting aswell so would probably want to change that aswell. so either = 2 or = 1 * FF_QP2LAMBDA.
