Syncing issues with audio/video (have searched github to no avail)

musicproject

I am doing a project. where i am mixing 2 vids (that bit done). I have a patch created that streams the wav of the video to an array (this bit also working). However if i launch the sound file as a subpatch and then launch the video, once the vid is launched the sound goes all wonky. How do I keep them in sync? I'd also ideally like to have sound files playing simultaneously if possible? I include a dropbox link to my patches, data files etc

My project is due super-soon and I've only been learning pd for about 4 weeks so any help would be very much appreciated!!

@musicproject Hello.......... yes I had been playing with that idea. Your mp4 files do not report their length correctly in frames on my computer........ so that cannot work, and also an end bang is never produced by [pix_film]...... for the same reason.......
They can only be played with "auto 1".
Try this>> dunno.zip
Any avi files that I have tried that report their length correctly can be controlled........
I am trying some file conversions......... I think yours must be compressed at a variable framerate...... which needs to be converted to fixed.
That could explain the sync issues......... and with luck you will need to change nothing else in your patch....... a BIG

@whale-av i tried that last zip out a while ago and no joy either. I actually found a zip online of someone who claimed to have synced a video and sound, patch and all, and got very excited. The video ended WAY before the sound! Daniel someone.. its a pure data old spice thing .. google it. I joined a google plus pd community, checked out the websites of the people posting frequently and sent many emails. I think i've emailed everyone but santa claus asking for help now, lol! Ah well, gonna go in and use the college macs tomorrow, see if it makes a difference.

Thanks for all your help, i reallly do appreciate it!!

@musicproject Hello Rachel.... The more I play with formats the more I am convinced that uncompressed avi is the only format that will work with the "sync" that you found. I have tested it with an avi film that I made and I can varispeed it without problems.. I don't know if you have that option though......(uncompressed avi)........
I really must get working with Premiere Pro again....... but way too rusty........
Anyway, I took your talking heads video and set it as constant frame rate using Mpeg Streamclip...... which is free here.........http://www.squared5.com/
Using the option to save as an mp4, but selecting the whole movie and fixing it first...... "edit" "select all" "Fix Time Code Breaks..." the movie produced should work better with the patch (constant frame rate). It still doesn't bang at the end, so no immediate loop solution....... but it should play in sync once........
You can produce an avi with that program as well..... but whether it would be better I don't know....

@whale-av Hi, I am a bit of an expert in Premiere Pro. I re-exported the movie at 960x540 size instead of 1920x1080 and adjusted the audio to 44100. I am currently uploading it to dropbox. Why AVI? an mp4 with those settings should work fine. I'll share the movie once it's uploaded, but am defo gonna hit the college labs tomorrow.

Goodnight!

p.s. Talking heads video? lol!
