    Hello. Just wondering if anyone could help me on an issue that i’ve spent this evening trying to work out.

    Here’s a brief explanation of what’s going on (sorry if it’s a little offtopic to start):

    I DJ with a friend of mine and want to add an extra spice to our sets by projecting the music video of the track that’s playing onto a wall.

    But the audio in the music video’s track is too compressed to sound good live so i would have to get the music video and the uncompressed track, find the starting beat on both of them and cut them to the nearest audio sample in premiere pro. Then put them at the same place in time so everything is in sync, and export.

    Here is the problem that i need help on. This is a picture of my project zoomed very far in.

    The top track is the music video track that i’m trying to align with the bottom track (the uncompressed audio track) that will replace the music video’s audio track, the track in the middle.

    I’ve already made the slices where the starting beat of both audio tracks are (to the nearest sample) so if i line both the audio tracks up the video will be in sync with the new track.
    The music video’s track and it’s audio track are slightly out of line because i had to unlink them to make a slice at the nearest sample, otherwise the edit gets pushed to the nearest video frame.

    I then tried to drag the middle audio track and the top track (two tracks of the music video) to the slice marking the starting beat on the bottom track, so both the 2 audio tracks line up. But the distance i’m trying to drag across is smaller than a frame, and the nearest place i can drag it to is in the picture below.

    I would just drag the uncompressed track to the start of the music video’s audio track but i don’t want to export the uncompressed track as i am scared of quality loss. Instead i am planning to export the video without audio and combining them in Quicktime, skipping the re-encoding of audio. I am only using it as a ‘reference’ track and not editing it.

    Is there any solution to make it line up? Or is there anything i can do when exporting it to add a certain amount of ‘blank space’ so it syncs up?

    I’d be very grateful if someone could share some advice and point me in the right direction, as i have tried everything i can think of and have had no luck.

    You cannot edit video shorter than 1 frame.
    However you can edit the audio to 1/48000 of a frame.

    Sorry Ann. I think you mean 1/48000th of a second, not a frame…
