moving all my media (audio, video) to the same hard drive (external, and then internal SSD) : no difference using the same low buffer size as i used to : 128 : no difference I'm gonna try some other things from now on (using a buffer size at 128 like i used to do for my previous videos, and putting all the media files on the same hard drive). It was a nice thing to investigate and discover (i didn't know about that option before), but it didn't solve my problem unfortunately. I also tried using +2048 instead of +2000, to have the same amount as my buffer size, and it behaves the same. when rendering : the rendered file has the audio (from the original video) in sync with the frames, BUT the audio/video from the original video file are still out of sync with the rest of the audio tracks So basically all your audio is in sync, but what you're watching (the frames)is out of sync with all the audio. when watching the (original) video in Reaper (playback), alongside the other (audio) tracks : the frames of the (original) video are delayed by 2000ms, but the audio of this video is still in the same place (so the audio of your original video gets out of sync). I just tried the +2000 ms in the Reaper video settings, suggested a few posts above. Go to preference - Media - Video/import/Misc :Īt the top of the window set the "video output delay" to 200 ms. Looking forward to hear from you guys since i'm stuck here. The only difference this time is that my video file is on an external hard drive, whereas my audio file is on my system (SSD) hard-drive. It drives me nuts because i've never had a problem with syncing when i used to render videos from Reaper before, and i used the exact same settings as usual : Trying all of these things above didn't change anything : in my rendered file, the tracks (audio vs video/audio) are out of sync. using a very high buffer size setting (i used the max available on my RME interface : 2048 samples)
MPEG STREAMCLIP RENDERING ANIMATIONS OFFLINE
trying different types of rendering options : offline full-speed, offline 1x, online 1x, etc making sure the playback rate is at 1 all the time I tried many things suggesting in the following "Reload this Page Tracks suddenly out of sync after rendering them" thread : They're both perfectly in sync when i playback in Reaper, however they are out of sync in each other on the rendered file of the master. But it's very fast and easy with Protools then, I schould keep this process. But I see the possibilité in Reaper it's why I wanted to try. In fact, till today, I used Protools for video export. Then mux the new audio back into the original video/audio file with Vordio.
Use Vordio or MPEG Streamclip to strip the audio file out to work on. Tell it the correct formats and it just works. Or it might just sit there and not so much even give you an error message. If you tell it to use a format or container that is non-standard, it will go malicious compliance and do just that. The big disclaimer with this - and I believe this is SOP with video apps in general - is you need to give it "legal" formats. I found this app Vordio that lets you replace the audio and remux new audio with the original untouched video file. I am aware that all end consumer video formats are lossy and that the aim is to preserve said lossy video without introducing re-encoding. Disclaimer: I'm an extreme Luddite with video!
