vegas doesn't seem to be using the proxy I generated for it. I made a 720p60 AVC , can vegas use that as a preview?
I have preview set to BEST/FULL
my proxy file is in same directory as original. format of original is test.mp4 format for my proxy is test.mp4.sfvp0
So far I tried, Best Quality and Good Quality will use original. But Preview Quality will use proxy.
with my user generated 720p60 AVC proxy file. it looks like maybe it's using it in draft/preview modes. as I get full 60fps, but I don't with good and best. also good and best use gpu decoding, but draft and preview don't, which maybe means something . I still am not sure, it could be just that draft/preview will play fine but it's still the 4k file. Is there anyway to tell?
EDIT: sorry did not update page, yes we agree preview mode is using proxy. thanks
Only problem I have is that vegas17 does not use gpu decoding for proxies, but in it's defence, it does not natively create a video proxy file that can be decoded using GPU so was not needed, but with enough AVC proxies it would cause a problem at 720p60. I only chose AVC because 4K can be trancoded to 720P at 200fps and I don't think you can do that with any other format. I dont' like waiting, that's the problem
Oh sorry j-v I was confused...yes my prefs looks like that
@Randy Brown Suggest you uncheck using legacy qsv decoding and enable use of your video board in video preferences. You won't have any chance of working with hevc without all the gpu help you can get. I'd turn off the power switch before I'd turn off the video board. 😃 Also make sure you automatically generated the proxy file when you first loaded the footage... it's a file with the same name as the clip but with an ".sfvp0" file type. If it's not there or is perhaps broken, you can make a new one by right-clicking on the clip in the Project Media window and selecting "Create Video Proxy."
sorry Howard, I see nothing regarding legacy in prefs...I see
under video tab
and this under preview
Preferences > File I/O?
oh silly me...I unchecked it but noticed hardware decoder is set to Intel QSV...NVidia NVDEC is also available, should I use that.
On another note, I turned in a support ticket on this issue a while back and they just asked me to send them a sample of the footage so I dragged a clip on the timeline (and let Vegas set the project properties) and played a sample and got NO dropped frames.
I don't recall making any changes other than unchecking legacy just now so I'm confused as hell.
@Randy Brown regarding nvidia file io... maybe? Try it but don't be surprised by crashing/hanging
"I only chose AVC because 4K can be trancoded to 720P at 200fps and I don't think you can do that with any other format."
Actually the internal proxy workflow is frame rate agnostic and the proxies used for the timeline playback will automatically adopt to the source media framerate. The only reason I could see to use AVC 720p60 instead of the internal MPEG 720p would be to save data by using a high compression.
I mean to say due to hardware encoding of AVC I can create a proxy of resolution 720p60fps for my 2160P60fps at an encoding rate of 200fps, so encodes proxy at 3x real time for this 60fps example. I'm sure that's the reason most people dont' bother with proxies and instead complain when trying to edit 4k direct, the internal proxy creator just takes too long, files are large and interferes with workflow.
I've done further research into this. I imported a 10minute 2160P60fps in vegas. I ran vegaspro17's built in proxy creator , and then I used a transcoder to make 720P60fps proxy using NVENC. These are results
VegasPro - 16m18s
3rd party transcoder using NVENC - 2m45s
They are day and night results. People would use proxys if vegas could create them so fast, and this forum would have hundreds less threads of people complaining about how slow vegas is at 4k. In vp18 they should implement hardware encoded proxys as an option, and turn on hardware decoding for proxys, or create a lower resolution proxy than the 720p i use, 480P I guess.
I don't use happy otter tools, but apparently his software already does this, and that's great, but it costs $80
Thanks for that. I did not know about it, and as expected using the swap files option does use gpu decoding, but I don't like that it's a pseduo proxy. and if I hit render without swapping back i'll be using a 720p file instead of 4k. I use voukoder so won't have the render template option to swap back to original on render. Still it's another option for 4k projects
