Playing a video with jitter and black cuts (embedded within the video file) don't show up properly
Apologies with my basic knowledge, this is my first time using Max.
I'm working on a project where I have 4 videos playing at once. The problem I'm running in to is with the video displays. The video files work perfectly when there's an image on screen, however, there are some moments when the video goes black (which is what I want) but instead of displaying the black frame as per the loaded video, Max just displays a frozen frame of the last frame before I cut to black. Is there a fix for this? I can't seem to figure it out.
please share the patch (select all, then right click and select "copy compressed", then paste it here in the forum), so we can help you.
black is not burned into video ?
if that is the case, you need to wipe last frame
Ok, apologies for the messy code. What I'm looking at is the video stuff on the left... still in the process of building out the audio stuff.
The black is burned into the video, here's a quick example taken from my actual piece: https://vimeo.com/858137101/e6dfb01e46?share=copy
Whenever it's supposed to cut to black, it just stays on the last frame of the man dancing until a new frame with a subject in it comes onto screen. The problem is, my project uses a bunch of video effects triggered by pots on my arduino (like contrast, delay etc) but i'd like for the black video moments to hit hard as the video plays, like the screen has been wiped. But, since my piece will be interactive (so people will be actively participating by twisting the contrast knobs and such) I won't be able to physically do anything to 'wipe to black' on my own while they're interacting, i need to video to just read properly.
Any help is very appreciated! Thank you!
without looking at your patch, my guess is the culprit is your video codec, and you're using a temporal codec like h264. if so then I'd recommend using something better for realtime video like prores or hap
Hmmm, Rob you may be right. I'm using HEVC to get the smallest file possible but perhaps that is the culprit. Will do some investigating with different codecs today. Thanks.
No matter what codec I use it's the same problem. So far the only solution I can find is to very slowly fade out my video to the black screen. It seems to be a problem with the way that jitter maybe bangs out the video (?)
