Hello All!
@ KnoWei: I’m really not sure it has much to do with playback devices, decoding codecs or bit rates. I have tried watching the created video on 4 very different machines (Pentium D, Athlon 64, MacPro running Windows within Parallels and an iPod nano) and in each case I see the same delays.
@ cad: yes I have read somewhere that mencoder has the codecs built in. Yes I played the MP4 back on my desktop machine – still the delay (I have tried both Windows Media Player and QuickTime Player). And presumably the Apple player on the iPod itself cannot possibly be using DirectShow/X? This all points to a software bug inside the SlySoft software? I have also purchased the CuCusoft convertor, and although the video quality is not so good (and it has a bug of not being able to read all DVDs) the video / audio sync is ALWAYS perfect. Again, this is the same systems that I am trying the SlySoft software.
Did you mean ffdshow or ffdhow?
From all my experiments, the audio/video sync seems very much something that is part of the data in the MP4 file, NOT part of the playback hardware/software. As said above, a file produced with Slysoft on any of my various systems will play back with delay on any of the systems. A Cucusoft created file will play back fine on any of the above systems.
I have a home video that I had previously converted to DVD using Pinnacle (about 2 years old). I tried ripping this to hard disc and then using ClondeDVD Mobile to convert this to MP4 – all worked perfectly, no sync problems at all!! Hmmmmm.
Is anyone from SlySoft still monitoring this thread?
I don’t have time today, but it would easy to record a home video of, for example, hammering in some nails to a piece of wood? Makes it very easy to test for sync? I would happy to send this Slysoft in an attempt to help “nail” this problem (sorry, couldn’t help the pun
).
All the best
