Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Low quality rendering video

Hi, I try to make a simple sequence with the new sequencer. When i render the cinematic, it rendered in low quality as if i put the scalability in low quality. In the editor the engine scalability is set to epic. Thank you in advance for your help Regards

just wanted to confirm the "Use Separate Process" worked for me! i knew in the past i was able to render videos out in very nice quality and for the last several times i used unreal the videos never came out sharp i thought maybe it was an issue with me running the engine in 4k and outputting to 1080p but using this trick i managed to capture a sharp clean video clip

thanks a bunch! seriously this is a MAJOR help as my main use for unreal is to make cool videos and no point in doing that if they all turn out low res!

Hi all, i had the same problem, when i want to render my sequence it starts ok but suddenly it seems like the scalability switches to low quality, no matter what i do always happens even if i set console commands for quality settings in BP it still lowers the quality, i dont know if you already have the solution, but i just figured out, and this is what i did...

Inside Render Movie Settings dialog, under General expand advanced parameters, there is an option called Use Separate Process and check it.

Now when you Capture the movie it will do in a separate process and not in the actual one in editor that its seems is very loaded so it cant handled everything.. well im a noob so maybe someone else can explain better.. the truth is that i dont have the low quality problem anymore...

Hope this help

Same problem here! We have solved in the same way: using the "Use Separate Process" options, and since we have many sublevel to load we set around 5sec of deley pre-warm up and 300 frames of warm up, but we hadn't to wait anything more than the time to open the separate process indeed (and everything worked perfectly)!

If someone from epic is reading here I'd like to add a point: it happened many times the exactly same thing but when I packed another project! To be more precise: in the editor everything was in good quality, even trying the New Editor Preview there weren't any problem, but as soon as I tried the Standalone Preview or the .exe after the package the scene was loaded as if was in low quality (exactly as in DaBoss' screen); the only way we solved was lowering the lightmaps of static meshes in the scene (hoping it doesn't low too much the quality of the scene); through the GPU profiler I found HZBO was taking ages to be calculated, but even tring to disable it and any other AO the problem continued and the GPU profile was saying a sublevel of "Base pass" was taking ages to be calculated; short story end surfing the web, finding few pages with high technical discussion in which I wasn't even understanding a word, and solved, as I said, lowering all the lightmaps!

Things to make sure of:

  1. Scalability are high (EPIC)

  2. At the rendering options of the sequencer, you uncheck "use comprission". Setting a high value is not enough to get you nice quality, but disabling it going to give you the best quality. alt text

Also a better quality could be always achieved by exporting sequence of images, and then put them togther with After Effects or such.

For anyone else encountering problems I found that in 4.20 I still got way better looking results by exporting without compression and then using a third party tool like Handbrake to compress. Make sure you have plenty of free disk space though!
