Wit Posted August 29, 2014 Share Posted August 29, 2014 I will have a screening tomorrow night and because the video files had to be transferred by web I send MP4 instead of the original files. What seize and format should a video have for a good sight when screening on a screen of approximately 2 x 2,5 meters? Is a mp4 of a HD 1920 x 1080 of 500MB enough?

utsira Posted August 29, 2014 Share Posted August 29, 2014 If the acquisition and projection format is 1080p then I don't see any reason to use a higher resolution. Difficult to say whether 500mb is enough without knowing the length of the film. If a blu-ray movie is say, for the sake of argument, 90-120 minutes at 15-30 gb total, then that works out as 160-250mb per minute. Quote Link to comment Share on other sites More sharing options...
Wit Posted August 30, 2014 Author Share Posted August 30, 2014 Thanxs - it's a 14 minute video of 500MB Quote Link to comment Share on other sites More sharing options...
dafreaking Posted August 30, 2014 Share Posted August 30, 2014 Thanxs - it's a 14 minute video of 500MB It's possible that you can have a few blocking artefacts depending on the complexity/details of the scene. Did you encode using CBR or VBR? Quote Link to comment Share on other sites More sharing options...
utsira Posted August 30, 2014 Share Posted August 30, 2014 I think the bit rates I suggested above are a bit high. 100 mb per minute or so should be more than enough. Do you have any way of previewing it? Even just watching it on a decent monitor, and really eyeballing it for artefacts can be useful. I'm sure most viewers will be engaged with the content and won't notice occasional blocking. Quote Link to comment Share on other sites More sharing options...
Wit Posted September 20, 2014 Author Share Posted September 20, 2014 I wasn't present at the screening but everything went ok I heard. Thanks everybody! @Dafreaking - Not sure what you mean I used MPEG Streamclip and your CBR or VBR were not there. Quote Link to comment Share on other sites More sharing options...
