Graham @ “Do a new SEPARATE Project with your GPU off and NEW Media which is CONSTANT BitRate.”

Graham what am I missing…….why would variable/constant bite rate make a difference here. If it were variable frame rate I would agree. Is there something I have missed, because I can not duplicate his issue and I’m using variable bit rate in my test renders. Thank You.

Hi Phil,

I downloaded the veg file, Thank You for posting. I used my video clips (1080-59.940p) from a GoPro Here3. First I muted all the sections you had increased the speed, then rendered out to 1080-59.940p using Magix AVC-AMD VCE and I could not detect any choppy movement in the P-n-P track which was your face video.

Then I un-muted all the section you have increased the speed (fast motion), and render it to 1080-59.940p using Magix AVC-AMD VCE, and again I can not detect any choppy movement in the clip I substituted for your face video!!

Looking over your project I cannot find anything incorrect that would be causing your issue. And I have failed to replicate your issue using your project file! This would pretty much point to something different in our systems.

As Graham has suggested, it may be fruitful to start another test project, using your source media from this problem project using the same work flow of different section in fast motion to see if you can duplicate your issue.

Have you performed a full reset of Vegas Pro 15? Hold down the ‘Ctrl+Shift’ keys while you double left click on the VP15 desktop shortcut. Then check the box ‘Delete all cached application data’, then left click on ‘Yes’

Best Regards……George

Alberto, I’m delighted to hear you have solved your issues and can once again proceed with your projects. Sometimes an easy fix and sometimes it takes a while, your persistence prevailed.

I may be repeating myself here…..

Mute everything accept the game video and it’s audio track. Render this out. Bring it back into your project to replace the original.

– or/and –

Mute the problem event in track 3 where you have speeded up the event, render out with that section muted and see if you have a different result.

There is something I think simple right in front of our eyes, but I’m unable to pick it out!!!

As for the files, we don’t need any of the source media files just the LCS_063.veg file. Can you upload that so I can download it and take a look. I will use my own source media files.

Best Regards……George

Philip,

What you posted is precisely what I asked for, Thank You. I see nothing wrong with your Project or Render template, although whenever I see problems with Magix AVC – AMD VCE, I switch to Magix AVC – Mainconcept AVC, just as a test to make sure it is nothing that the GPU is doing.

Your source media also looks good and the only difference I see is the game source is 59.940 fps and the face source is 60.0 fps, but that is not going to cause the difference you are describing.

I think it maybe something you are doing in your work flow, can you tell us something about how you are putting the clips on the timeline, tracks and speeding up the game footage? If when you speed up the game footage it is somehow linked (grouped) to your face footage this could be a cause, although I’m trying to think how you could have done something that would have caused this and really cannot think of anything!

How about muting out the game footage track and rendering out just the face footage. Do you see the same issue in around that 4:05?

We may need you to post somewhere your project.veg file so we can download it and take a look. The .veg file is rather small and will not include any of your video clips.

Best Regards……George

Terence, as a quick and dirty test, can you drag and drop a still from your Windows Explorer window directly to a track in your timeline?

I’m on Windows 10 and Resolve 15.2.2, how about you?

Hi Philip,

How about a screenshot of your Project Properties and Render Format Template? Also, using the free Mediainfo app (in text mode) post a screenshot of the specs of your game footage source media and your face video source media files that you are putting into Vegas.

Best Regards……George

– Dynamic RAM preview max back to the default of ‘200’. You only need to increase this in the event you are Building a Dynamic RAM Preview. NOTE: If your playback Preview does not improve you could also set this to zero just as a test.

– Set ‘GPU acceleration of video processing:’ to ‘Off’ (will need to restart Vegas). Does this help?

– Right clip on the Preview display. From the options is ‘Adjust size and quality Optimal Playback’ checked? If so un-check this option. Does this help?

– Close Vegas, reboot your computer. Do not start any other programs. Start Vegas Pro, new project, add only one of your ProRes source clips and bring that to a track on the timeline. Does this clip (event) run smoothly with the Preview set for ‘Good’ or ‘Best’?

– Where is the source ProRes from, a camera or screen capture, or something else? Can you post a screenshot of the source media specs using the free Mediainfo app set in text mode?

– You may also want to perform a full reset of Vegas, hold down the ‘Ctrl+Shift’ keys and double left click on the Vegas Pro desktop icon. Check the bos ‘Delete all cached application data’, then left click on ‘Yes’. This will rest Vegas Pro to it’s installation default settings and delete the pesky cached application data, which over time accumulates and sometimes causes Vegas to do strange things. In this case most likely will not help.

Will wait for you reply to this for further ideas. I can tell you I have a much less powerful PC than yours and I work with PorRes HQ 422 10 bit and DNxHD/HR 422 10 bit source media and can get reasonable playback speed (usually full speed with color correction, LUT’s and transitions) at Best/Full or at least Good/Full.

Best Regards……George

Terence, interesting you are having this issue. I can simply drag and drop a still from the Media Pool onto a track above the clip track (jpg or png), or place it on the clip track. Vegas works the same way they treat still the same as video clips and play the length you set it as. Also, like Marc I prefer png or tiff as they are usually better quality than jpg, easier to color and grade and if you need alpha it is there.

Best Regards……George

Yan, another long shot if you haven’t tried it yet, a full reset……hold down ‘Ctrl+Shift’ keys and double left click the desktop icon for Vegas. Then check the box ‘Delete all cached application data’, then left click on ‘Yes’. This will reset Vegas Pro to the default installation setup and delete the pesky cached data that sometimes makes Vegas do strange things out of the blue.

Best Regards……George
