max resolution for 2:1 ratio renders in VEGAS Pro 18

Stephen-Shelton wrote on 7/4/2021, 9:27 AM

Hi. I'm creating a 360 deg video and struggling to work out the best/highest resolution that Sony Vegas can render in. 360 deg has to be in 2:1 ratio resolution. YouTube recommends 7168x3584 or 8192x4096 as best resolution to upload in, but I can't seem to make SV render to this. I've done 4096 x 2048 ok but it would be nice to have even higher detail. The default render options don't have 8k but I've worked out if you have your project properties at 8k then 8k render option suddenly appear. However these 3 only 8k options that appear in MAGIX HEVC/ACC MP4 format have set resultions 7680 x 4320 or 8192 x 4320, they are greyed out and can not be customised. So my question is what is the best 2:1 resultion format I can get out of SV? Any work around/trick/codecs to get me the best youtube options? Additionally does anyone know software that can render at 7168x3584 or 8192x4096 if SV can't? Many thanks

You could use a render type which allows the render frame size to be adopted to the project frame size which is the case for AVI and Voukoder (if installed).

Vegas Pro 18 will do 8192x4096, but you also need a codec that supports that resolution. You can usually type custom resolutions into the dropdown boxes.

Thank you - So next question if ok please; any idea what codecs will work with SV do 8192X4096 and where I can get them from or how to find them? I can't find any SV support/help for this anywhere, hence coming on here (I did try hard first!). As said, no customisation possible (as far as I can see) as the only 8k options I could find had the resolution greyed out, couldn't alter it and only 3 of them there, none at 2:1 ration. Many thanks

Yes, thanks, that did dawn on me. I'm just trying the process atm. First fantastic, the AVI method works, only of course it's making a rather mega sized file, but that's my problem to deal with. I've just rendered and now checking an AVI will upload to youtube? I have also just found and downloaded Voukoder and going to try that, hopefully that will be the ticket, smaller files than AVI maybe? thank you so much. I was just waiting to test them out before replying. My last comment was really if there were also any other options, but if this one works then no worries. thank you again!

Holy Cow! Voukoder is loads smaller. I'm testing a 4 sec bit of video. AVI was 8Gb Voukoder was 0.1Gb. Just need to see if they upload to youtube ok and how they appear, the latter not too compressed I hope. I suspect you know all this already, but just to let you know I'm following your kind and excellent help and for anyone else that stumbles across this searching for the same as I did. Thanks so much!

The file size of your AVI output depends on the codec you use for the AVI wrapper. There are some AVI codecs (like Grass Valley HQX, which needs a separate codec install) which allow for much smaller output data sizes than the often used uncompressed version.

But if it is used for YouTube uploads you should be pretty fine by using Voukoder and H.264.
Note that you can easily adjust the quality with Voukoders "Constant Rate Factor". Default is 23 which should be fine for most cases. But if you want to be sure not to waste quality then set that setting down to 20 or even 18.

It's all worked very well for me on my trial. Youtube takes time processing 8k but, hey, that's part of the course. Also thank you for the tip about setting the quality, I hadn't even noticed that first off but even the default of 23 looks pretty good. I can't thank you enough for this, it has totally changed how I'm now planning a whole range of videos I have in mind, as after my initial exploration in SV and www research I thought wasn't going to be able to do the optimum quality. You're an absolute star!! 🙂👍

I don't recommend using AVI for Youtube for a number of technical reasons, time notwithstanding. @Marco.'s advise is the best option available. Since you are using UHD source(?), the x265 encoder in Voukoder will produce smaller files yet, at the cost of increased encoding (and YT processing?) time. Start at RF23.

Unfortunately, the files we give to Youtube, assuming they meet nominal quality standards, do not affect Youtube's modest output quality, not even a little bit! That means the dog does not wag the tail, so fortunately for you, you can give up the search for the holy grail of upload formats. It doesn't exist, beyond supporting your format.

Also, keep in mind that you gain absolutely nothing by encoding and uploading at a higher resolution than your source format (you didn't mention what it is).
