Failure to render

KingGeorgeXX wrote on 4/8/2021, 5:27 PM

I have created a virtual choir video with approximately 60 video/audio tracks. The timeline has a mixture of MP4 and MOV files. I used the picture in picture effect to create multiple scenes of sized videos that range from 5 to 7 PIP in each scene. Each video is synced to an audio track. Most video tracks have some type of effect applied such as sizing and brightness and each audio track has volume envelopes and eq. I have trimmed all videos to about 15 seconds to reduce the rendering process. The render will work anywhere from 41% -86% but never completes. I'm using Pro Edit 18 KingGeorgeXX

Welcome to the Magix user to user forums.

First, you've posted to the Video Pro X product area but then say you are using Pro Edit 18, which could imply Movie Edit Pro. So, which is it? The latest version of VPX is 18 so, presumably, that?

Then, please tell us a lot more about your computer. 60 video/audio tracks is going to be pretty demanding on any computer system. This post will show you the sort of details we really do need to know. Also, how much free hard drive space do you have?

When you write that you have trimmed all videos to about 15 seconds to reduce the rendering process I fear that will not be the result! Each individual video, with its effects, transitions. PIP etc., will almost certainly require rather more rendering time than a single, longer video which does not include those effects.

One final thought: how many hard drives do you have and do you have the source video files on the same hard drive as the one you are exporting to? Is Windows, and possibly also VPX itself, installed on different drives?

Greetings your majesty and welcome to the humble user to user forums.

To add to subject Jeff's concerns, I am also concerned at the line

The timeline has a mixture of MP4 and MOV files.

in your post.

Do all the files for your project come from the same recording source, ie, a camcorder?

If not.

Are all the files the same resolution or frame rates?

Are any files variable frame rate rather than constant frame rate, say from an iPhone or screen recording using Zoom, OBS studio or similar screen recorder?

I have this horrible vision of the program trying to cope with more than one frame rate at once or worse two or more sets of frame rates changing with sets of frame rates going both up and down at the same time while the program is trying to add and remove frames from them to produce a constant frame rate export.

This has all the hallmarks of being a potential nightmare of a project without careful forward planning.

Your humble servant and with deepest respect.

Ray.

Thanks, Jeff and CubeAce for your suggestions: I am using an Alienware Aurora 7R with intel i7 6 core processor, on occasion during rendering, I would use the progress feature to see how the processor was performing. Most times the processor was being used at 75-85% capacity while the memory was cruising along at around 3.5 GB. I had upgraded my RAM to 64 GB for this project. The frame rate could be one of the problems because I noticed that some of the videos were shot on an iPhone, the majority of the videos were recorded using a computer and program designed for this purpose. I have two hard drives, the Vegas program is on my C drive which has approximately 40GB of free space. My source videos are on the D Drive which has 2 TB with 1.3 TB of free space. I was rendering to the D: drive. During this project, I was able to complete one test render (not sure how that happened) which I found needed some work on several of the performers to sync with the music, but was never able to get a final complete render and had to use the test version in our church service.

This type of project is very popular with houses of worship at this time and I was creating this video for our church. I have seen videos of a virtual choir with 50 or more singers in one screenshot, synced to music. I thought for sure Vegas could accomplish this task. I've been using Vegas since Version 4 and never had a problem until this project from Heaven has stumped me. Any suggestions on how to manage the files, the best technique for sizing videos, and could it ever be possible to create a virtual choir with say 35 singers on one screen with Vegas? Your help is very appreciated because I know the choir director will be wanting to do this again.

PS Windows and Vegas are on same drive.

Hi George.

While what I have written above may be relevant to your problem I'm afraid the users of this forum only use Movie Edit Pro and Video Pro X Magix Video Editing programs and not the Vegas line of Magix video editors and the way both sets of editors work and the workflow is different.

For that reason we may not be of much help any further. I suggest you create a profile at the Vegas forums and talk to the equally helpful people you will find there that will better know the ins and outs of those particular editing programs. The Vegas help forums can be found here.

Any help we may offer here may not actually work.

Sorry.

Ray.
