Rendering slow? Is it normal?

[kiliand84824139]

Hello,

I do have a question. For some reason the rendering in Adobe Premiere CC takes forever. My system at the moment is a quite weak one so I don't expect a huge project to be rendered in less than 12 hours but it should not take up to 4-5 days.

I am using footage from different cameras, unfortiulay, and therefore the files are in different formats. mp4 and mts (full hd 25 fps). However, I had to cut most of the footage by "hand", so I did not work with Multicam due to some glitches with the footage. I do have 4 video-timelines active and 1 audio-timeline. I have done a pre-rendering with only one camera angle and it finished after 10 hours. The problem is, if I want to render the whole video with all the different camera-angles and colorcorrections, cuts etc. it will approximitly take up to 95 hours!

The files are stored on a NAS Server and the local cache and files are stored on an SSD. The rest of the system is pretty weak. It is an Intel Core i5-2450M and 8GB of RAM.

Even tho the hardware mentioned above is quite weak, I assume it should't take so many hours for a 3 hour project?

Have you enabled Maximum Render Quality & Render at Maximum Depth in sequence settings or in export settings if yes then uncheck both the Maximum Render Quality & Render at Maximum Depth option it should render/ export faster.

Thanks for your answer. I have unchecked these as well - same result. I also did check some settings, deleted the cache etc. and still the same. Could it be, that the system is really just took weak?

Work as suggest by Dean, it might resolve the issue.

Could you outline what else you're doing in the video?

I had a project file once (done by someone else) that gave an estimate of days for rendering. When I drilled down to why, I found that there were image overlays that were 5000 pixels wide (or thereabouts) stretched down to 1000 or so. The images were very large and were creating a lot of processing power to resize for every frame. When I resized the images, the render time went down from days to a couple of hours.

So, there may be some other things in your project creating a CPU load.

What you could do is take a small part of the project into a new sequence and see if it can render quicker. Going through each part may help identify the most troublesome for rendering.

Hey guys, thank you for your reply. The project is a conference, that lasts overall 2 Hours 51 Minutes. I haven't added anything except a .png (1920 x 1080) as an overlay for the whole project. I did some colorcorrections to the footage and I actually cut the last 30 minutes in a Multi-Cam sequenz, because these files haven't had any glitches.

However I tried to let it render over night in the office and after 14 hours it was at 22%. I cancelled the rendering and I have skipped trough the first 20 minutes that have been rendered and I did not notice anything, that could have taken so much time.

Almost 3 hours, 4 video tracks, color correction, weak machine: why wouldn't it take days? Yes, I'd keep that possibility in mind. Is the NAS speed a bottleneck?

I would select a 5 minute section of the timeline and see if you can render that. And calculate the full time from that sample to test whether that is simply the bottom line.

Are you just rendering? Or are you exporting?

[SAFEHARBOR11]

Make certain that the Sequence Settings match the footage, and that the Export Setting also match (unless you specifically need to change to a different resolution). If for example the frame rate differs at some point in the workflow, that can add a lot of render time for the conversion.

And what format are you exporting to? I don't believe that has been asked. Please provide a screen shot of the Export Settings panel, as this can often be quite revealing in finding issues. I've never edited off a NAS, but I can't imagine that helps any and is a likely bottleneck in moving data around. Could you maybe make the SAVE location of the export a LOCAL drive on the machine, so Premiere is not both READING and WRITING to the NAS at same time?

Thanks

Exactly JEFF !!! I forgot to mention that I once tried rendering and exporting footage

via a NAS system and that was an awful experience

When you click on 'Project Settings' - 'General' - 'Renderer'

What do you have as options ? can you send a screenshot ?

If it is software only and no other options available, rendering would become slow

especially if you apply color correction and specifically Lumetri

talking about multicam means there is a nested sequence, that which slows rendering speed as well

I suggest you only do the cutting first without any effects, export and then apply the effects and export again
