I recently made a short film, and it played fine in Quicktime on my iMac. When it was video projected at a film night however the image was distorted - it had horizontal lines running through it and the projector seemed to struggle with blocks of colour. This was a domestic level projector, and the film was running off a MacBook Pro.
I am intending to show it again at a festival and would like to know what I can do to render it best for projection.
My current export settings are:
Preset: PAL DV
Output: 720 x 576 25 fps, lower, quality 100
Video codec: DV25 PAL
No frame blending
Maximum render quality
Thanks for any advice
I'm not sure how laptop and projector were connected, but I do know that all the other films shown that evening were fine - just mine was distorted. Yes - it would have been playing on Quicktime. Thanks
Well unfortunately the output mode and player would have decided this. The lines are likely from interpolation which means the player was dealing with the material as Interlaced or the player was outputting Interlaced and the Projector was displaying in Progressive. You can also get that from Interpolating 25 frames to 30 frames if the Player is playing everything in NTSC and your material is in PAL. Often times differences in Codecs will cause that to not interpolate correctly in the player.
That is the best way to resolve this issue since DVD Decks are firmware programmed to handle this interpolation very well. Software players have to many version differences which include codecs that can run into issues like you ran into.
i always avoid playing multimedia or video in .mov format during my live event.
most of the time it will stuck, stutered, out of sync, etc (especially if the file size is large) can't afford to face that kind of problem.
what i always do is to convert it to .mp4 with good quality format and play it from VLC.
double check before i run it from start to the end.
