    IslandPlaya has mentioned before, use image sequence for playback in sequencer. I was doing that for 4.25.3 . Do not use 4.26.0 for image sequence, it will fail!

      Please Epic for the love of all that is good fix this. No matter how awkward it is for you to do so.

        I had this issue ( When rendering out sequencer scene with a TV playing Media Texture on it), You playback the render and the video on TV screen is way too fast. To fix it go into Level Blueprint, where you can set the speed for the Media Texture and slow it down from an Event tick. Please see Blueprint and example attached. Create a variable called TV Screen which is a Media Player type, pointing to the File Media Source. Then add Set rate node and Multiplication node to rate on Set Rate Node. Connect Set Rate and Multiplication node to event tick. Make Multiplication node a really small amount. ( I used 0.09) This worked for me. It might not be 100% accurate but it slowed the Media File on TV down to an acceptable speed.

          Thanks Graeme, this is a good work around i'd say, although for me I multiplied it by 3.5 instead of 0.09 so i'm guessing this is going to be different for everyone.

          I'm currently rendering 24fps at 2160p, tried doing 24fps 1080p and it turned out the same which wasn't what i expected.

          Hopefully we can get a good workaround for all as i cannot get normal play even with image sequencer which is the only way i render to get smooth playback when not using media textures.

          Also using Unreal 4.25.3 in bootcamp on a mac pro 2013 if that helps anyone troubleshoot.

            Hi, I'm a cinematographer quite new to Unreal. I have the same issue* for chroma keying. I'm trying to synchronize an actor inside a video texture within a sequence, the problem in my case is that the speed of the video texture gets slower depending on the resolution of the rendering... becoming useless...
            It's really a pity because the preview is really awesome...
            I hope UE team can help with this! Pleaseeee!

              I would also like to vote for this to be fixed. A lot of arch viz guys can run into this same problem if not fixed.

                I am truly hoping for a fix but I am a bit devastated to see that there are threads on this forum dated back from 2015. I don't think the guys are planning to fix anytime soon.

                  If you don't want to have problems with the video render in sequencer use this method i use: https://www.youtube.com/watch?v=vNv7...xzanderTheGeek

                    I described this workaround at the start of the thread. It is very inconvenient and you have to revert back to an mp4 if you want to package your product to a reasonable size.

                      Thanks alexzander1947 so much much for the video. It really fixes the synchronization problem. Just note that as in this way is just necessary to have video in a frame by frame sequence, without using VLC I could export it from Final Cut pro in my case and changed the media source from file media source to image media source. I understand IslandPlaya mentioned it before, but I could not understand how to do that, thanks anyway...

                        thank you for the Video! Would this work with png sequence in 4k with alpha channel?
