Improving editing of 1440p high bitrate videos ?

dape wrote on 6/19/2022, 7:41 PM

Hey guys, so i used to edit 1080p videos in VP without problems even with high bitrates (like 50-60 Mbit).

Changed the monitor to a 1440p and now i record my games in 2560x1440 to a 80-100 Mbit bitrate for good quality. Unfortunately now VP19 seems to struggle with editing these videos straight from my external usb3 6TB hdd..

Is there a way to make the editing more fluid without dropping the preview to Draft? I used to be fine with 1080p videos in Good/Half..

The system is pretty beefy: 12700k with 64gb and a rtx3080 - the only problem is the weak link to the usb3 hdd :)

Thanks !

Obviously try a sample file on your local ssd, it doesn't matter if normally that's not standard operation, it's the first variable to rule out. If you are using default NVENC new settings, you can try changing Max B frames to 1. You could turn on legacy AVC decoder. with a 12700K you don't need to use the subpar SO4 GPU decoder with 1440P AVC files created by OBS, you have lots of CPU

Thanks for replying @Former user !

I want to continue editing the video files on the usb3 hdd ! Editing on the smaller local ssd works great.

The files were recorded using Intel Quick Sync in Xsplit Broadcaster. Editing in VP is based around the nvidia rtx.

I'm gonna test the legacy AVC decoder and see if there is any improvement on the usb3 hdd based 1440p files.

You should make sure Xsplit is recording in CFR not VFR, maybe Vegas could handle 1080P VFR, but not at 1440P. Also if Xsplit encoder allows you to choose max B frames choose 1. They scrub so much more smoothly in Vegas compared to recordings with 2 B frames from OBS

You should at least look at the response time for I/O from your USB hard drive. Compare it to an internal NVMe drive.

I have a USB3 dock attached to my laptop at the moment. Here are the results for:

2TB Hitachi 3.5" HD

1TB Toshiba 2.5" HD

The Toshiba is still sitting in the dock from when I removed it from my son's laptop 'cause it's useless as a Windows boot disk if you want to get anything done.

As Todd mentioned, the format the video is recorded in will have a huge impact on whether or not it edits smoothly. If you still cannot get smooth performance at 1440p, you can always use proxies, right clicking on the files in the project media bin and selecting "create video proxy". This creates 1080p proxy clips that are used anytime your preview monitor is set to "draft" or "preview" quality. Setting it to "good" or "best" uses the original media files. Once you go to render, the proxies are ignored and it renders using the original media files.

I don't have enough space on the internal ssd unfortunately. I want to edit straight on the usb3 6 TB hdd.

Uh, i totally forgot about proxies ! Got so used to edit 1080p in Good preview that i.. forgot that feature.. Will try, thanks !

Proxy rendering is of course the stock solution.

Also, maybe back up and look at how you are capturing your gameplay. I agree that if you must use the hardware QSV encoder you will need that overly high bitrate as machine encoders generally suck in the quality dept.

On the other hand, if you can capture at the frame rate you want using say, x264 software codec with zerolatency tuning, which is all I-P, you should be able to get as good or better quality results at half the bitrate, or around 30-40 Mbps for 1440p. That of course, will preview smooth as butter on your timeline.

The first time I saw one in about '96 my first question was, "Does that thing really need that little fan on it?"

Can you share a screenshot of your capture settings?

@Musicvid

The thought just occurred to me that I still have a Pentium 120.

Actually, it was a Pentium 90 that I ran as a 120/60. I mastered and burned a lot of CDs with that system. My first SCSI CD burner cost $529. Notice the copyright on the chip '92-'93. I did my work ~1996-1997. After adding a SCSI CD burner, a sound card good enough to do the job, Sound Forge/CD Architect, I was into that project for $1200.

Thanks @Musicvid ! @RogerS Xsplit Broadcaster has a very very very basic Intel QS settings window, its just the old CQP where i can set few presets and custom, they all set qpi, qpb and qpp, thats it. I am thinking to go back to OBS which has a more refined QS settings part with ICQ, LAICQ and the old CQ.

Did not manage to power up the computer today but wanted to respond to you fine gentlemen faster. I may solved my problem with the proxy use: just few more steps of workflow for me for more fluid preview in VP..

It's a wonder!

Ordinary citizens (Normalsterbliche) call it bottleneck.

Alright: seems VP19 decodes the main video file (14 GB) by NVDEC (~40-60%) and encodes the proxy file using the CPU (~20-30%). Let's see.

Took like 5 minutes and generated a 7.5 GB proxy file, to be honest i expected a bigger proxy file :)

Wow: Preview Half works flawlessly but i don't like the video preview quality.. I switched to Preview Full and it is quite usable !

Thanks guys ! Proxy workflow for my 1440p videos from now on it is.

RogerS wrote on 6/20/2022, 6:32 AM

If you go back to OBS you should be able to get usable files directly from it. One additional hint is to change autokeyframe interval from 0 (auto) to 1 for better playback. Good luck!

Vegas proxies are XDCAM-EX (MPEG-2). I can see no reason to set your preview to anything but Best/Full.

If i change the preview to anything higher than Preview/Full i will use the original file so.. i am back at my original usb3 hdd bottleneck problem !

Oh yes I forgot it switches back. Comment removed.
