Two video tracks; when one speeds up, it makes the other choppy after render

[George Dean]

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.

Best Regards……George

Hey George!

Thanks for checking it. I could very well be our systems, though it was working perfectly before on the older version I had (13, I think?).

If it is system issues, well…

Specs:
I7 4790
Asus Z97-A motherboard
Asus R9 390x STRIX
16GB DDR3
480GB SSD
3TB HDD
Corsair C70 case
Corsair H100i cooler
EVGA 1KW PSU
Asus 23″ IPS monitor
CoolerMaster Storm mechanical keyboard w/CherryMX Browns

I built it myself a few years ago, so may need to update something?

Anyway, thank you yet again!
Phil

Hi George. I noticed Philip’s MediaInfo which reveals the original MEDIA has Variable BitRate (VBR):

This isn’t Variable BitRate for Encoding, its the VBR embedded into the Media itself. Then it’s the Maths that VP is having to do to keep up both with Preview and then encoding. I try and keep things simple to give VP a chance. So, I shoot with CBR whilst others maybe capturing Screen VBR. My invitation is to use CBR Media and see if he gets the same issues.

Does that help George?

Done some further interrogation on MY Media and:

1] Canon XF300: CONSTANT Bitrate
2] Canon SX60hs: Does have a Variation of Bitrate from CLIP to CLIP, with a MAX of 25Mb/s and an AVB 23Mb/s, but yours hits 57Mb/s.

I reckon it’s the your combination of VBR; the high value 57Mb/s; Vegas plus your PC has to deal with those rates that’s messing with you.

Looking back over your Posts there is something inconsistent with your Capture, Render and playback I don’t understand.

Thank You Graham, I read your reply too fast and I think I thought you were referring to his renders, I see where you are going with this now…..hopefully that is the fix.

Hi George – You Do? Well, maybe…. Our friend needs to get a consistent workflow that will accommodate his wishes.

Hey George and Graham!

Thank you both so much for looking into all this. It does look like it’s coming from my game video track then? I think what it is on my side is the “upscaler” device I use for the PS2 (allows their initial cable to turn into an HDMI cable for my Elgato HD 60 Pro device). On my original post, I had put that it seemed the game slowed down or sped up just a little while I was trying to record my face at the same time of play (probably unnoticeable to the naked eye) in order to keep the game’s graphics looking better than what they’re supposed to be. It is perhaps due to this that there is a variable bitrate?

Either way, that is the only method I have of record my PS2 gameplay. Other systems, as they have HDMI cables by default, go directly into the Elgato, and did not seem to have much issue with anything. I think I’ll just let my sub’s know that it’ll either always be choppy, or I’ll just go back to doing only my voice, which may be easier.

Again, I do appreciate both of you very much, and thank you as always,
Phil

Hi Phil,

Beings how you are stuck on your capture method, I would make one more try at using an intermediate file. I suggested this earlier in the thread, but I may have not explained it properly and I’m not sure if you tried it and if so what the results were.

After you record your game footage, bring it into a new project and render out an intermediate in something like Sony XAVC Intra or Magix Intermediate format(s). Either of those are going to be much larger (file size) than your original, but the Magix Intermediate is going to be the smaller of the two options.

Then bring that intermediate back into another new project and preview it. If there appears to be no playback speed changes, then I would use this intermediate rather than the original for your project that you do to include the face video.

If this works you have some extra steps and can decide if they are worth it.

Best Regards……George

Oh! Ok, George! I did read it but was not quite sure what you meant by it. I will absolutely try it out!

Thanks for the clarification and steps, because I am still learning Vegas in that sense. ^_^

Thanks!
Phil
