Video falling behind audio

Whenever I watch a video on my MeizuM6 the video falls a little behind the audio. This is not normally frustrating unless I am watching a music video and I hear the vocalist sing something then like a second later the visuals of him saying it appear, making it horrendously apparent.
The longer the video the farther behind the video falls.

Is it just me? Is there anything I can do to fix this?

Thanks in advance!

Use "Audio Interleaving" in VirtualDub to fix any sync problems.

1: take a piece of the video where you have good sight on people speaking.

2: then determine if the audio is too late or too early (use positive values if the audio is too early, negative values if the audio is too late).

3: then fill in a value for example 1000 (if the audio is too early) or -1000 (if the audio too late). (1000 = 1 second)

4: look at the same sequence again and determine if the audio is (still) too late or (still) too early.

5: adjust your value according to what you've seen, you should be able to make smaller steps when you get nearer to actual right value.

6: repeat 4 and 5 until you get the audio in synch.

7: save your file.

Nice tip but I really think that this should work properly. This is a big negative for me from Meizu. I think it sucks big time. I escpecially bought the player for it's capability to play movies but now it is just a frustration. I hope it can be fixed through firmware and if not I will never buy this thing again in my life.

This certainly doesn't happen with all movies... I've only seen it happen on two videos, out of about fifteen, say. It must be something to do with the sound and video interleaving, as said by "goods"... must be some mode that it doesn't deal well with - anyone managed to round it down to what it is we should avoid, exactly?

I am having the same thing happen with video falling way behind audio. I used the profile previously posted for the Miniplayer. i have not had a problem on short files(Mpgeg-1 converted), but on a full length movie(Vob) when I open the Vob I get a "Parsing Interleaved Mpeg-2 File" message with a processing. The video is fine, the audio is just way behind - The audio is also very low level(even cranked up on the M6)

Any ideas?

Thanks

I agree 110% with dreski. I bouth a Meizu mainly cause it clains it can play xvid. But, IT DOES NOT DO IT PROPER. Meizu is fooling customers. ALL my videos have the exactly same problem. It's not one or two of them. its ALL of them.

And, im not unexperienced with video edition at all. Im been using VirtualDub for YEARS. I know my videos are ok, they play fine in my computer, in my DVD Player, they play fine everywhere, EXCEPT in the Meizu.
If u buy something, its supposed to do what they claim.

I was considering to buy a Meizu M8, but, after all the frustration with my M6, I will never buy another Meizu Product.

The player does play Xvid as advertised, certainly it could be better. But look at a lot of other players, including many more 'serious' DAP's that require you to convert using their own software to some obscure format, give me the Meizu method any day.

The Meizu does have an awful lot going for it, its an incredibly sexy device, it has an awesome screen on it, the UI is very competant (with just the bizare control layout change when playing videos).

I specifically bought the Meizu because of its ability to play Xvid which was initially a dissapointment, but once the software was setup, now I know to chop the movie length files into segments (a one click script on linux thankfully) and now I am pretty darned happy. Sure it would be nicer if the files played direct, with no conversion, no crop, no chop, but the player is so sweet in other ways I can now easily live with it.

I don't know how much time you put to it, but sometimes its worth putting up the odd hassle for the good of the whole, think living with some supermodel with PMS, 7days of hell for 21days of pure joy with an angel (assuming its not some superbitch ). Metaphor aside, the Meizu is a real nice device, it just has issues which hopefully Meizu is working on and given that updates are still coming I have little doubt that its not the case.

For the last 4 hours, I've been trying to get a decent port of an Mpeg2 video with varying levels of success. Using VdubMpeg2 as described elsewhere in this forum gave very smooth frame rates, but the audio consistently lagged behind the video - just enough to be majorly annoying.

I've spent the last bit, trying to adjust this in Virtual Dub - but the given solution is not working, nor do I suspect it would work as the audio is in sync on my PC - it's only when transferred to the device I see an issue. (I suspect it's a codec problem. To that end, I've tried several different codecs as well)

As to the specific programs, I've also tried vid convert, and SmartVD - both had additional problems as well. Smart VD gave a compressed screen ratio with no options to expand it.

Iriverter pretty much synchs the audio to the video, better than anything else, but it's still not perfect.

Badak seems a bit more promising - still not perfect, but hopefully I can get something acceptable.

I have to say I am somewhat disapointed, but I'm not giving up hope yet. I purchsed this mainly to let my kids watch video on the go. Fortunately, I ordered it from someone here in the states - JTC Electronics. I talked with them this morning, and they indicated that if I couldn't get it playing video acceptably, I could return it. So that's an option. Incidentally, I highly recommend them - it was shipped extremely fast, and he was a very nice gentleman to talk to over the phone.

i think the above poster is right - Video length has alot to do with it, so the solution may just be to break up longer videos into smaller files. I have had very little difficulty with videos 20 min or less, but I just put my first full length movie on my 8gb M6 and had the audio issues(I tried the video converter and VirtualDub, and the original video converter did a better job, but it still is unusable on this conversion). Unfortunately, that is the problem that all of these devices have(and computer technology in general), is that there are a lot of little quirks and video converting is not just one click and you go(I have used a number of video editing utilities and have about 6 loaded on my computer right now). Maybe thats why Ipods are so popular, Apple has made it simple, but you pay dearly for it, and that's what the nontechnical majority want - I personally like the ability to tweak things the way I want and not be restricted in what I can do, but I waste a lot of time too

Thanks for the input, but I'm sorry, that's not the problem I'm running into here.

I have not tried to do any movies as yet - simply some 5 minute test clips, and a few 1/2 hour TV shows.

Clips processed with Badak are lagging as well.

I'm now trying MediaCoder. The first pass at 400Kbps video @ 20fps (as defined in the miniPlayer Profile) resulted in stuttering video, and the furthest out of sync audio I've seen so far.

Please let us know, if you were successfull. I hate that sync problem

Hi everyone
I had this problem before and I checked every videos with a bad sync and all of them had a VBR (Variable Bitrate) encoded Audio instead of CBR (Constant Bitrate).So I put every videos in CBR and so far so good.I hope it is a solution of your problem guys.

I believe I tried this, but I'll give it another shot. I did manage a sync of sorts - offset the audio by 250 ms in vdub, or 100ms in iriverter (not the best solution, but it works - sorta). However, I've now run into other issues - namely fast forward does not work with longer files (> 1 hour).

Any suggestions there?

My intent for the M6 was to see use mainly as a PVP, and and frankly, it's a little frustrating to run into one issue after another with something it claims to support out of the box.

Sorry if you've already stated this before, but what firmware are you running? Almost each firmware upgrade has fixes for smoother video playback.

FWIW, using Badak, that resulted in audio wildly out of sync for me. What program and settings are you using?

Thanks

S 2.002.3

Thanks for asking.

Yes, I Agree its really frustrating. Let me share what I found until now:

CBR or VBR mp3 in audio = does not matter, the audio is out of syn in both.
My Firmware =2.003 (latest one)

If I convert a video and its in sync at the computer, I already know it will be OUT of sync in my M6. So. If the video looks "right" after beeing converted, I need to do it again until I get a out of sync video at pc.

In fact, I found the problem is: M6 always put the audio about 280ms out of sync. If you can manage to encode the videos and put a "counter delay" of -280ms, it will end in a file that is out of syn at pc, but perfect in M6. BUT, the biggest problem is.. not every source video can be converted with this "counter delay". Sometimes, the source video dont accept the audio interleave, and even if I put the right values at virtual dub or virtualdubmod, or virtualdubmpeg2, any of them, the ending video is SYNC at computer, or... better saying, out of sync in M6, and cant be converted at all.

I just bought 4 of the 4GB for my video production company so all my partners could walk around with our video demos in thier pockets and wow clients with the little player but the audio sync issues is TOTAL BULL5H!T!!!!!! W-T-F? Why sell a player that doesnt work like all the other 5h!tty Chinese companies, I thought I was on to something but this has turned into a $550 waste of my time. I'll stick with the Creative Zen Vision:M which plays everything I throw at it and has a way better screen. I should have spent this money on a couple Vision:Ws and had a killer 4.3" screen.
I AM SOOOOOO FREAKING DISSAPOINTED!!!! I thought Meizu was going to have higher standards than the rest of the Patent infringing, Intellectual Protperty Violating, knock off manufacturers in CHina... OH WELLL

This is pretty much what I've run into.. GOD I HOPE THE FIX THIS!! I'm about to throw these at the wall!!!

jcolaent audio sync issues are hardly noticable , players are standardly 150 ms sync out and the m6 is 100 extra sync out , that is 1/10th of a sceeond more , you cannot tell atall , and anyway if you are a video editing team then it is easy to edit the audio sync 280 ms less...
