Video Rendering in Full and Extra HD

Has anyone done any rendering in Full and Extra HD (Pro version v2.5)?

Seems in a test using the standard Lumion hill top SkUp house example that I get massive bitrates, Full was 83,588kbps and Extra was 144,703!!!  Rendered at 1 Star.

Now this might be OK, except high bitrates cause staggering or stalling or just wont play in various media players, although  I can get the Full to play for this render in both WM and VLC(most recent).

For the Extra HD:
1. WM won't play at all, VLC will but stops or staggers.
2. WM won't play even if I cut the bitrate back to around 15k, VLC will
3. Windows (Explorer) does not seem to recognise the frame size and wondering if this is the issue with WM.

So:
issue 1: high/excessive bitrates with no ability to control except by post convert changes, meaning extra time on render process.  Is there some way to have the default bitrates set much lower?
Issue 2: problem with playback of Extra HD.

If you can play back the high bitrates depends on the hardware you are using ofcourse. If you need a lower bitrate you can always use adobe encoder or something like that to reduce the file size.

We use a high bitrate because the quality is better and you can always simply scale down.

Most gfx card support hardware accelerated playback of h264 1080p movies. If you have a harddrive and no SSD the speed of the harddisk also is important.

I think your suggestion is good to add a bitrate setting in the pro version for saving movies.

Our idea is that Lumion produces the possible quality and if you want to size down you just use a free tool like WinFF or commercial tool like Adobe encoder to scale down. There are even encoders that use the GPU so the conversion is quite fast.

I can imagine that with lower bitrates you might find out that you wasted time rendering because the final bitrate turned out to low and you have to render your movie again.

Hi Peter, thanks for taking the time to test the WQHD (2560×1440) format in Lumion.

Windows Media Player can't play 2560x1440 videos. This is a known limitation of Windows Media Player. VLC can play videos in that resolution though but this resolution/bitrate combo requires fast hardware.

Hi, thanks for feedback, and also confirmation on WMPlayer.

I heard of a brand new i7 with GTX680 and it couldn't play the Extra so wondering how high it too high?  Seemed 144,703 extreme increase on say about 15k for 1080p.  My PC's far less powerful, but for 1080p I know somewhere around the 8 to 15k is fine for playback.

If doing top end video size then there's bound to be most clients end user PC's unable to support anywhere near kbps rendered, so would need to play on own system or its ofr special large displays anyway, or be aware that need to chop kbps setting back in a post video edit for other playback.

I did a quick test in cheepo video converter and max kbps it supported anyway was 50k.  :D

You can always try Media player Classic Home Cinema Edition. It also has hardware acceleration.

If you need to convert you can just use WinFF. It's free and has the best h264 compression there is, just like Lumion! They both use ffmpeg library.

Good tip, Remko - Media player Classic Home Cinema Edition can play a WQHD (2560×1440) format video from Lumion just fine, even on my aging PC.

I find it the best player for windows on several fronts.

Ha, thanks Remko.

Haven't seen that interface around for sooo long, good old media player lives again  :D
