Question

Glitch after cut between clips

Hi Adobe Community

 

I have a two-camera interview on my timeline: MXF clip from a Sony FS5 on V1 and MP4 clip from a Sony A6400 on V2.

 

When I cut from V2 to V1 I get a glitch (see clip with still). I have found a workaround which involves removing the clip from V1 when V2 is active and then extending the start of the next .MXF clip to under the active .MP4.

 

I'd rather not have to do that; there may be instances when it's impossible.

 

Any clues?

 

Martyn

    Were both cameras shooting at the same frame rate? Does the issue go away if you have a black matte under everything on the first track?

    On a side note, I recommend editing shoots with multiple cameras using a multi-camera source sequence. It allows you to edit on a single track while easily switching between cameras. Check out this guide for more details: Creating Multi-Camera Source Sequences.

    Cheers,

    Hi Paul. Yes, both cameras were shooting at 25fps.

     

    Do you mean a black matte on V1 and then footage on V2 and V3? I've never tried that but will give it a go if the problem persists. Can you explain your thinking on this, please?

     

    Curiously, when I reposition the start of the clip on V1 to the end of V2 now, like it was in the original edit, the glitch has disappeared. I get the feeling it's to do with Prem Pro accessing the file, for some reason. But I have identical edits elsewhere in the timeline and they play and output fine.

     

    Thank you very much for the suggestion to create a multi-camera source sequence. I will certainly do this for my next project. So far I've not had a problem working on multiple tracks, so have never tried it. Time to learn and improve!

    Hi Martyn,

    Yes, I'm suggesting adding a black matte on V1 with footage on V2 and V3. This helps determine if the overlapping footage is actually fixing the issue or if any footage has the same effect.

    To me, the glitch looks like a long GOP encoding error. This can happen when exporting to a low-bitrate H.264 using source files that are also H.264. These kinds of glitches usually occur around edit points. If this is the case, I would suggest exporting to something like ProRes first, then convert your ProRes to H.264 or whatever your delivery format is.

    Hope this helps! If you have any more questions, feel free to ask.

    Cheers,
    Paul

    Did not mention Premiere version and build. OS or comp specs.

    If you are using a nvidia card make sure you have the most current Studio driver installed.
